Looking to get 50 mph out of her, she is bone stock right now. What would be the most cost effective reliable way to achieve this? Can I use stock motor and esc and just upgrade batt and prop, or should I purchase a 120 amp or better esc? If you can give me exact specs that are recommended that would be great. Thanks

swoopo, check the neighboring threads, plenty of info on how to achieve 50 there. Youre looking to upgrade to either a 5s or 6s lipo, you'll need a new esc either a 120 or 180 amp. Also will need a higher KV motor. If you get a high discharge 5s lipo setup you can get close to 50 with an x642 and the stock esc.

I replaced the stock esc with a turnigy 180 and run a SS 230 s/b by dasboata and my GPS read 47 mph on 40c 5000 mah 5s zippy's. I also run a kintec off set rudder. I think with a little more ajustment I can hit 50. Also replace all connectors to 5.5 bullets.:rockon2: This was on the stock motor, you don't need a new motor just a good set up.

I am looking at buying a seaking 180 ESC or Turnigy 180 ESC but cant find them anywhere in the US? I would like to get expedite shipping from us location, ebay is all HK or UK?? Anyone know who stocks these in US? The set up i have decided to run is 180ESC, (2) 6s 5000 mah turnigy 35c lipo's, 42x55 grim racer prop on stock motor for now. does anyone see any problems with that set up?

Ah 2 6s lipos? You mean either 2 2s or 2 3s?

As far as I know the only place to grab the 180s is hobbypartz.com or hobbyking.com or other chinese sites... Steve is out of them at the moment (stinky). Thats a good setup if the 2 6s batteries is an error (are you running them in seris or parallel?) otherwise youll hit the moon with that setup... then it'll blow up

OK forgive me, im trying to educate myself through the forums for this is my first brushless set up. Right now i run (2) 2S, 30C, 5000mah venom hard pack lipo's with a 42x55 grim racer prop, esc and motor are stock, from what i gathered through the forums is install a 180 ESC, and bump the battiers too (2) 6s packs, is this wrong? Am i running 4S total right now beacuse i have (2) packs? So if i bumped too (2) 3S, 5000 mah, 30C lipo's that would mean im running a total of 6S? sorry! Thanks for the help!

Ok to answer your battery question...

If youre running them in seris (like the stock setup) you'll be doubling the voltage... so two 6s lipos gives you a 12s lipo without increasing mah. This setup would destroy your esc (as it is only rated to go to 6s). In parallel you would maintain the 6s but double the mah rating.

See this here:
http://offshoreelectrics.com/info-pages/serial-parallel.php

For more info on setups and such check out the tips section on the main OSE page... you can also browse my website as I have been collecting and putting forth basic information on rc setups here: https://sites.google.com/site/jac4412/electronics-batts-etc

You either want 2 3s packs to give you 6s in seris or a 2s and a 3s pack to give you 5s. Most of the users on here run 5s at around 50 mph... that is dependent on the motor, battery discharge rate, prop, and esc.

Don't apologize for asking questions! Keep asking them its the only way we learn and get better, it's a community to help each other!

Happy to help

FYI theres alot of little things youll have to do as well... like switching the stock dean connections over to 5.5 bullets, and deciding whether to use a separate battery pack or not. Ask away!

Ok now i get it, i might go with 45C lipos from John's battieres i found on ebay, says you can get 45mph plus out of then and its (2) 2S packs 5000mah, i can use all stock componets. Maybe that with the 42x55 prop will get me close to 50mph? Thanks for the help!

Mmm...

I saw those batteries... call me skeptical, I question all of those "custom" battery packs, plus I've never seen anyone us them... maybe someone can pipe up who has used them? Theyre also pretty darn expensive... shop around a bit before you pull the trigger! Plenty of options out there

Also, read through all the information... With youre setup you'll have to watch temps on the stock esc

LOL...May be wishfull thinking..Your just not gonna hit 50mph on 4s..Not with the stock electrics.Youll barely get even close to 50 on 5s..Ive tried it all..If you want to go faster your just gonna have to either run on 5s or get a different esc and motor..Thats just it..

What prop is recommended on 4s and 5s with the stock esc and motor on MG? (pls include brand and spec)

mike I believe darin said he hit close to 50 on stock electronics (maybe I'm just misremembering something but I'm pretty sure he hit like 48)

I use johns batteries fastrcbatteries 2s 45c 5000mah with noticable difference on acceleration and top speed from my hobby people 2s 35c 5000mah. I wouldnt say 45mph probably high 30's with stock setup and x642

Hit Ben up for the 180, see when hes getting more in.

Im running a Turnigy 120, 4S stock motor and a worked M445 and getting 44mph. I wouldnt see why 50 would be un-acheivable w/ 5S? I havent tried it as I run my boat in the LSO class and do not wish to change it, however, I may play w/ it one day just to see what it will do. Id have to go back, but I thought Darins run was on 4S and thats whay it was so "impressive". :confused: high 40s on 5S wouldnt be....

Here is a US seller. I've purchased several times from Alex and had good service.

yup on 5s...

Just Pmd Darin. It was on 4S :buttrock: BUT, Darin knows his ish and knows how to seriously work a prop. Im sure 50 is do-able on 5S w/ the factory motor, its just gunna take some tinkering. I ran a 32" cat w/ the PB motor and esc on 5S and ran 52.7. Its on here somewhere from about a year and a half ago. 32" Imex Nichols cat. then it went :flashfire:

Heres a 49.3 mph 5S run w/ Proboat esc and 1500 Motor out of the BJ26. I changed the prop 1 run after this which was several weeks later and it made 2 successful runs before it bit the dust. this is in a 32" much heavier boat...
Sorry for the camera quality and filming.. its hard to do everything by yourself at the same time.

Using a Prather 230, on 4S, I was able to consistently run 46-47mph with the stock system, and I hit 49 at one point. Not sure I'd recommend it on the stock 45A ESC for very long, however. Looking at over 80A continuous.

Gens ace batteries from hoppypartz.com are awsome roar aproved and relatively cheap! I hit high 40's on 4s but changed motor and esc m445 prop seems to give the best all around performance. If you got the time replace the esc and play with adjustments you can achieve high 40's all day long with stock motor on 5's but there is a lot of fine tuning to get it just right and every boat is different in some way. Also keep checking the swap shop I found my 150a hobbywing and my seaking 180a there for very good prices there's always one every couple of days just have to keep checking and be first in line to get it. Also as most have mentioned upgrade connectors ec5 connectors for the battery and esc are great and 5.5 bullets for the motor are a must when you start playing with big vlts and high amp draw

Also... This was using quality Thunder Power batteries. Don't underestimate the benefits of having REALLY good cells....

Deff go with the t180 esc after you kill that motor as I did on5-6s you can chage the bearing or get a cc1512 1800kv than you can run all you want knowing you have headroom with your esc and a quality motor with replaceable parts replacing bearings in the pb motor is a pain and the castle motors run so much more smoothly

:iagree: I had one start to go, I gave up trying to replace the bearing. Kudos for sticking w/ it and getting it done. I yelled at mine and the Mrs said I had to fight nice or I couldnt play with it anymore :cursing:

Cc1512 is nice but not enough power for my needs but definetly a good reliable motor. I've only had 1 outing with it but on a windy choppy day while taking on water (kept losing a cooling line off my esc) on 6s my best was 48.7mph with a m445. I'm sure with a few more adjustments no wind or chop id hit low 50's. Also the taking on water didn't help the matter never a zip tie around when you need one so had to call it day early. Ill give her one more try tomorrow before I move onto my next motor

I did all this with a bj and it's a little smaller for grins I put in a 1515 on 4s and a m545 and it's a different beast but that was reaching the hulls speed limitations in the bj so I'm moving on to project break a ul1

Btw 1512 1800 on 6s is plenty a handful
