    Default Miss Geico 24 Upgrade -need help please!

    Dear all,
    To introduce myself first - Im Trutz from Germany all new to the rc thing.
    In advance please excuse my noob questions and my englisch as well
    I recently bought the Miss Geico 24. Its all stock still - 15t 550 brushed Motor watercooled 3,17mm shaft , 50A Esc; running on a 7cell 4500 nihm pack.
    Are there any small other options to improve the speed Without making her brushless? Prop for example? What do i have to look for to not burn the components when using a bigger prop and what size or Material sgould it be? Its Plastik 2 blades at the Moment btw.
    If not -can anyone recommend a good working brushless setup
    to bring her around 30mph?
    Sorry for my noobisch questions-still learning
    Regards

    I wanted one of these boats really bad for a brushless upgrade, but couldn't get answers to what prop I should use. So I went with a Shockwave 26V3 instead. I kept all the info I collected about the MG24 for future reference.

    As far as trying to make your MG24 faster, the stock motor is about the best you can hope for as far as brushed motors go. Brushless is the only way to go these days, the prices have come down so much that it's often times cheaper to go that way. The stock motor mount will allow you use most all common BL motors on the market, so you don't have to worry about doing a bunch of mods to your hull.

    I was going to use this motor... https://forums.offshoreelectrics.com/...t-1500Kv-Motor - had I purchased the MG24. Seaking 60A ESC (running parallel with the hull) would fit where the stock unit is now, perfect place for it because that's where the water line goes in.

    As I said in the beginning, I was having a hard time getting answers about props. The steerable outdrive on that boat means the prop is submerged; having a submerged prop means running on the small side because the entire prop is underwater the whole time.

    I attached a list of props I compiled that might work on that boat, I can't give you specific info because I don't the answers. Maybe someone can contribute with that info.

    Hopefully this info gets you going in the right direction, good luck

    Hey JW thanks for the quick answer. Looks good for the begining!
    How would the watersupply work for that esc? Can i just use the existing
    watercooling by adding a "t-part" on the entry an outlet of the boat and connect the esc to the same watercycle?
    Which lipo setup would you suggest for the combo?
    2x2s to get it eell ballanced?
    Regards

    ...How would the watersupply work for that esc?...

    It depends on the ESC model, some have 2 water pipes, some have 4. I'll use this model for an example because it's a popular brand (its exact same thing as Seaking ESC)... http://www.hobbyking.com/hobbyking/s..._Boat_ESC.html - you would take the water line from the transom & connect it to one of those pipes, left side pipe would be good. Yes that means cutting the existing hose to make fit correctly, remember too that you want nice even bends.

    Next you run a hose from the right side ESC pipe up to the left (port) side of the motor cooler (look at the pic in previous post) and plug it into the water pipe. Take the existing hose that goes from the stock motor's cooling coil to the outside, unplug it from the cooling coil and plug it into the right side (starboard) pipe of the brushless motor cooler, that's all there is to it.

    Attached is one of the pictures I collected while thinking about buying one of these boats, it shows you where I am talking about putting the ESC.

    BTW: It's best to cool the ESC first, then the motor.

    Batteries... I don't think there's enough room for 2x 2S LiPo's, and it would probably be too much power for that size boat; especially with the outdrive, they can get damaged from too much power. Single 3S LiPo would be the most you would want to use with that boat. I'm sure a 3S would fit the existing battery tray just fine.

    Here's a good example... http://www.proboatmodels.com/Product...ProdId=PRB0650 - it's the boat I got instead of MG24... Notice it has a 1500Kv BL motor running on a single 3S LiPo. There's a reason why Proboat did that

    The motor in that Shockwave boat is basically the same motor as the PB 1500Kv from previous post, only now it's made by Dynamite & pretty blue colour.

    Hope this info helped to answer your questions & give you idea's about how to upgrade to brushless.

    I have this boat and have run it a few times and its great but the battery doesn't last too long. Its the speedpack 2400. Will changing to LiPos give me a longer run time

    Yes if you go with a higher mah packs,
    And you will need to time your runs so you do not run the pack down to far.
    Do you have a good charger for lipo's ?
    It should be a little faster to.
    ? ONLY IF THEY WORK

    No my battery is Dynamite Speedpack 2400mAh Ni-MH 6-Cell Flat with EC3 Connector so I guess I would need a new charger. Would I need a new ESC?

    ...my battery is Dynamite Speedpack 2400mAh Ni-MH 6-Cell Flat with EC3 Connector so I guess I would need a new charger...
    My Shockwave 26V3 came with the exact same battery & charger as the MG24's, there both worthless piece of sh*t. PB put them with the boat so beginners can go to the lake right away.

    Update: most RTR boats & trucks come with a cheapo wall wart charger (see attached pic) that takes overnight to charge even a low mAh capacity battery. The Dynamite 2A charger is FAR bettery than those, but it keeps turning off before the battery is all the way charged - I tested mine to make sure it works. More info is here... http://www.proboatmodels.com/ProdInf...m_11-28-12.pdf

    The battery is also very good quality, but the low mAh capacity limits your runtime's as you have found out. That's why Lenny told you to get higher mAh capacity packs, it's the main thing that gives longer runtimes.

    I have cycled my SpeedPack batt twice (completely discharge then charge), both times it took a 3000mAh charge using Onyx 220 charger (1.5A charge rate, no safety timer, no trickle). The only other NiMH packs I have that are that consistant are those Associated batts I have.

    In the long run, you guys will be much happier with LiPo's, just be sure to get a good quality charger, you can get an adapter that will connect it to what-ever battery connectors you decide to use.

    I would recommend replacing the EC3 connectors, all they are is 3.5mm bullets in a pretty blue case, that's too small. Go with at least 4mm bullet connectors, most people on this forum say 5.5mm, EC5 connectors have 5mm bullets, for your setup they would be fine.

    Pick which connector type you like, change the connector on the ESC to that connector & get batteries that also have that type of connector, or change what ever the battery came with to your connector choice.

    Lenny suggested LiPo's, in a addition to higher power density, they are also much less weight.

    I have 2 of these... http://www3.towerhobbies.com/cgi-bin...ssing%20Data** - actual weight on postal scale = 10.10ozs

    Also have 2 of these... http://www3.towerhobbies.com/cgi-bin...ssing%20Data** - actual weight on postal scale = 14.10ozs (with Traxxas connectors)

    That's a quarter pound difference!! That extra weight is a lot to the stock motor. It means it has to work much harder to make the boat go the same speed.

    The ESC in that boat is the same as the one that came with my SW26V3 (http://www.proboatmodels.com/Product...ProdId=PRB0600), it does not support LiPo's, that's why lenny told you to time your runs.

    Here's an easier way... http://www.hobbyking.com/hobbyking/s...rm_2s_4s_.html - plug the balance wire from the LiPo battery into this device and it will sound alarm & flash the lights when you get to 3.3v/cell. That tells you it's time to bring your boat to shore and change batteries.

    HK has a couple other models to choose from too - pick out which ever one you like best.

    Hope that helps you guys out - happy boating

    You need to get a good quality charger that can do Lipo's, you can get an adapter that will connect it to what-ever battery connectors you decide to use.

    Lenny told you to go with higher mAh packs because that is the main thing that gives longer runtimes.

    If you like EC3 connectors fine, get batteries with that kind of connector. Or change the connector on the ESC to what-ever type connectors you like... Traxxas, 4 or 5mm bullets, etc. But it's a good idea to decide which one you like, then change your ESC connector & get batteries with the kind of connector you choose.

    Lenny suggested LiPo's, in a addition to higher power density, they are also much less weight.

    Just stay with a C rate of 30c or higher for lipo's,
    And look on hear and see what is working for other on hear.
    Just do your home work on handling the lipo's and you should be fine,
    Hears some info for you to read and learn about stuff.

    Hey Lenny...
    In this thread... https://forums.offshoreelectrics.com/...hockwave-V3-BL - the OP asked if this battery... http://www.valuehobby.com/power-syst...ah-3s-trx.html - would be ok for sport boating.

    I replied "Will that battery work? Yes, would I use it, no. Nothing less than 30C for boats - higher (40C +) for hotter setups / racing".

    You said 25C would be fine, just check temps.

    Now your saying 30C minimum, what gives??

    Please don't get me wrong, I'm not bashing (read my recent posts, I only say good things bout you), just trying to figure out why the conflicting info

    For the record, I still stand by my 30C minimum for boats recommendation & practice what I preach... all my boat packs are 30C - I don't race or run high current setups. Have 7x 2S Bashers + those two 3S's, goofy name but great packs. Becuz mAh & C rating is the same, I can use them for 5S in my IM31.

    I use the Onyx 5700's (25C) for my pede, they run cool to the touch, bottom of 8.4v humps get hot as hell. Have LVC set to 3.2v/cell per you recommendation, when the truck stops CellMatch tells me 3.5v/cell, probably cuz of the slight bounce back common with LiPo's.

    The op in this post is looking to mod the setup in his boat,
    So with modding 30c would be the better way to go or higher.

    Like I said,
    25c and and that stock boat will work fine.
    It is a low amp draw setup and the esc calls for no lower than 20c cells.
    I have tested 25c cells in just about all of my boats and have had no problems with them,
    You just need to have the boat setup right and running smooth.
    And yes the more C you have the more power you have when it comes to FE setup.

    Lenny is very smart about LiPo's, when I first started using them he helped me the same way he is trying to help you guys. Follow the links he gave you in post #11, there is a lot good information there.

    Most of the fires you hear about & see vids on YouTube are because of stupid people who do not read or follow the instructions & proper safey measures. Some of those fires are on purpose becuase somebody was bored and had nothing better to do.

    There seems to be mixed feelings about those "LiPo safety bags". Apparently there is a lot of difference in the quality, more money does not always mean better quality. A cheap bag isn't really going to help much if a fire does start. Probably better to buy those at your hobby store instead of the internet so you can see it in person before you buy it.

    The main thing with LiPo's is: read and follow ALL instructions, NEVER leave a LiPo battery un-attended while it is charging. Do not charge at more than 1C, 1C = mAh of battery x 1, example: 5000mAh battery, 1C = 5A charge rate, or less if your anal like me, I charge at 1/2C or less.

    Only use good quality chargers, not those cheap piece of sh*t like you see on eBay and most of the ones HobbyKing & HobbyPartz sells. The DuraTrax Onyx 235 is a good budget charger, doesn't have a lot of special / advanced features, just charges & balance's the battery.

    If you want features like: discharging, safe storage mode & so on, then you need to speed some extra money and get something like these...

    I also found some Hyperion chargers last night, forgot where, but they are also good quality and the prices are reasonable, about $100~$125(USD). They too have some of the more advanced features like the E-flite charger.

    About makes of batteries... here is an excellent thread with tons of good info on batteries... https://forums.offshoreelectrics.com/...s-for-the-buck - people talk about batteries they have good luck with and ones that are not so good. The main focus is on affordable batteries that are also good quality.

    Alot of people in that thread and on other forums say good things about Gens Ace. Alot of people also like Sky LiPo (and some don't), but HobbyPartz has been out of them forever.

    Ok, that should be enough info to keep you guys busy for awhile.

    Please be careful & safe so you can enjoy your boat hobby.

    Loving all the helpful advice on this forum. Glad I read this before purchasing a cheap charger off eBay!

    I'm now looking around for a battery, charger, motor but trying to get some tips on what to choose. Being a newbie to everything RC I am quite enjoying finding out new things everyday. For instance yesterday I found out that I can get a water cooled jacket for a motor! Sounds basic but when I was looking at motors I was wondering how the pipes attach to it!

    I have the Accucel-8 charger with 150w at 7a model 8150,
    This puts out some good power and works very good. http://search.yahoo.com/r/_ylt=A0oG7...5FCharger.html
    I also have a BC6 and two other one,
    But not sure what they are at the moment.
    The BC6 work pretty good to for what it is.

    And I run that 8150 on this PS.

    With these chargers can I just plug them into the wall. Just looking around and I'm a bit confused as I get the impression reading other forums that I need a special power pack connected to the charger to reach the charging capacity of the battery.

    Hi all. I'm new to this forum and RC boats. Like others I have recently purchased a Miss Geico 24 and would like to upgrade to brushless. I have found some good information in this thread, but still have a few questions. I have already purchased the motor http://www.advantagehobby.com/215909/DYNM3835/ and esc http://www.advantagehobby.com/215903/DYNM3810/?pcat=361. The problem I am having is that the shaft on the new motor is thicker so I need a new collet nut. I cant seem to find any specs on what size I would need. Can someone provide me with this info? Also can someone recommend a 3s battery to run with this setup. Is there anything else that needs to be changed, anything I should look out for? Thanks.

    Hi MagnumTA did you have any joy with the collet nut? Don't really have an answer but looking on this site http://www.funrcboats.com/ProductInf...uctid=DYNM3835 it says that motor fits the Geico 29 so maybe you need a collet nut to fit that model.

    That is a lot of motor for that hull,
    The shaft on that 1500kv motor is 5mm.
    You need to find out what size the flex shaft is in you stock boat.http://www.proboatmodels.com/Product...ProdID=PRB0507
    Or up grade the shaft and hardware to some thing better for easy maintenance,
    And all around better setup than stock stuff.
    This looks like a nice mod on the 17" hull that could be done to the 24" hull done the line.

    Do you think one of these would work? http://www.hobbyking.com/hobbyking/s...exi_Shaft.html

    I'm not sure what the od of the stock shaft is. This collet should work http://www.proboatmodels.com/Product...ProdID=PRB3308 as its listed to be used with that motor on the MG29. What is confusing me is that it is also listed as being used in the MG24. I have emailed horizon to confirm that it will work. I'll measure the stock one tomorrow when I take it back out.

    The stock flex shaft on the MG29 is .150 and the coupler is .150 to 5mm motor shaft.

    Great choice of motor, I got the PB version for my Rio EP, still suffered from torque roll, no where near as bad as the 1800Kv from the IM31, but she would still roll over at top end. I have to disagree with Lenny about that choice, if a SW26 can handle it, than there's no reason a MG24 can't, especially considering that the MG24 is much wider be-cuz it's a cat.

    DL the BJ26 manual, you'll find instructions in it for adjusting the outdrive. Between that and battery placement you should be able to get a good balance.

    I put the Tacon 2700Kv motor back in my Rio and ran it on 8.4v humps with a PB ESC from MG-v1, set timing at 0° and she hauled the mail, using the stock plastic prop no less - 1st time I've used the stock plastic prop with the BL setup, normally run Kintec CNC'ed alum props.

    Also replaced the mickey mouse aluminum coil coolers I've used in the past with this one... http://www3.towerhobbies.com/cgi-bin...ssing%20Data** -- no leaks, good water flow and the motor stayed cool to the touch.

    Only issue was the PB ESC kicking LVC in when there was still plenty of battery left. I've already replaced it with a Seaking 90-amp unit so turn off that stupid LVC and play with the timing some more. Last time I was on this board there were several threads on the subject of motor timing. Got me to experimenting, all I can say is; more is not always better, so far less has been better for me.

    I'm puttin the PB 1500Kv motor in my SW26 with a Seaking 90-amp speedo when I get the time.

    About the coupler issue... I used this coupler... http://www.offshoreelectrics.com/pro...ct-ocfhe5mm13S -- to connect the PB 1500 to the Rio's flexshaft. Got it and 3x of these... http://www.offshoreelectrics.com/pro...ct-ocfhe5mm15S - from Steve when we got a breif break from the oppressive heatwave that's been kickin butt on the western USA this summer.

    Used it once and now I don't have a use for it. The 5mm-> .150's are for my SW26 (with PB 1500) & IM31 + 1 spare.

    You guys gotta take Lenny's advice and determine the diameter of the stock MG24 flexshaft. Between all of you guys, somebodies got to have friend with a dial / digi caliper so you can measure, only way your going to know for sure. Once you guys have determined what the diameter is, then you'll know which of the Octura couplers you need - be sure to get a short one - they have the letter "S" at the end of the part number. I've got plenty of pix of that boat, almost got one, so I know what it looks like under the hood / boot (or is it bonnet??) for you Brits.

    That's my biggest complaint about Horizon, for some reason they don't like to provide specs... for any of they're stuff, and it's not just boats either, I've got 4-Blade heli's, try finding the deminsions for ANY of the Spektrum air Rx or Tx's

    About the battery question... http://rcjuice.com/Basher-Series/Jui...-45C-Lipo.html - I''ve got 7x 2S's + 2x 3S all 5000's, goofy name, great product. But the 3S 5000's are a bit on the heavy side (13ozs actual measured), that's why I'm suggesting the 3500's - those just came out recently.

    Hi JW, thanks for the response. I actually made the swap of everything a couple of weeks ago. Lenny's advice of the coupler being 5mm>.150 was correct. I have only ran it a couple of times on NiMH 7.2v and 8.4v packs. Everything was good and a definate pick up in speed. Can't wait to see what it will do with a lipo in it.

    However, I tried running it this past weekend after it had set up for a week and it would not come on. If someone could help me with this issue. The batteries were fully charged, but nothing happened when I flipped the switch on the ESC. I popped the batteries in my traxxas stampede and everything worked fine so I know they were good. Next, I wired the stock ESC back up to the receiver and still nothing. So... I'm thinking maybe the receiver has gone out??? Anything else I should check? How do I test the ESC to make sure it is on? Thanks

    Hi All

    Finally got my hands on a digital calliper and measured the flex shaft on the 24" and it read 0.147" / 3.78mm.

    I decided to fiddle about with the stock motor and wanted to take it out but I could not remove the coupler from the motor shaft. I loosened the tiny black screw but it didn't come out. I didn't want to pull the coupler from the shaft too hard incase I damaged the motor. Can anybody give me some advice.

    Take the set screw all the way out and it should come right off easy.

    If on a budget, the set up from a revolt would run well
