Boat questions Shockwave 26

[pandianightcross]

Heya all. Im new to the website and RC boats , not RC in general I love my offroads. I had a few questions concerning a boat I got.

First the boat is a Shockwave 26 brushless. I love the look of the boat and it performed very well for the first run I took her out. However on the second run the prop broke one of the blades in less than 2 minutes , I was still able to get it back to shore luckily but dissapointed than in less than 2 runs I am having to already replace the prop. I run a 2s lipo , lipos are all I use now in all my RCs.

Running stock is fine with me , Im not a racer just someone that goes down to the park and will run his boat at the local pond for fun.

Anyway is there anyone that makes a steel prop for this boat that has about the same specs as stock? Durability here to me is the key , dont want to replace a prop every other run.

Another thing I noticed was on the rudder , the shaft between the u joint and the prop , on pictures Ive seen the white plastic bushings look almost flush , on mine they are not and have just a tiny bit of space on each side of them. All grub screws were checked and everything is tight and good. Just needed to know if that was normal or not.

Sorry for the long post and any help would be appreciated!

Hi contact horizion hobby they will give you the updated metal prop for free the new boats come with the metal prop because the plastic ones on the first boats always broke.

also there should be a little play in the drive line.

It sounds like you are happy with stock speeds, which is good!

I have seen on these RTRs that the electronics are pretty much maxed out, so beware that getting any bigger prop may kill the ESC. the hull is designed for those speeds and could easily turn into a headache if pushed to go faster.

Yea I am just a casual boater do it for recreation and relaxation. As for the prop situation , its turned into a headache!!!! Horizon replaced the prop for no charge with the stainless , wich I managed to install with no problems.

But now Ive ran into a bigger and much more of a headache!!!!! Ran the new prop , and ran great for about 10 minutes , luckily it was close to shore when it quit running and I was able to get it pretty easily. Popped off the hatch and was met by a billow of smoke! I quickly yanked out my battery , the battery was fine no damage , no puffing at all. I noticed the esc was smoking to holy heck , I quickly disconnected it from the reciever and pulled it out of the boat.

Ive never had problems ever dealing with a esc on fire , Ive dealt with esc that have gone bad in my RC trucks , but never a issue such as this. I was running a 4500 mah 2s lipo , the lipo is completely fine (I always balance charge lipos). The esc was on the lipo setting so that wasnt the issue. Ive had this boat for 2 weeks and im getting frustrated cause now the inside of the hull where the esc was has a nice burn damage , outside is still fine and boat floats with no issues.

do I contact horizon again and let them know and hope they replace the esc? Or do I just pony up some more cash and just buy a seaking esc? I really dont want to have to sink a ton of money into something for just leisure play , maintaning a rc is one thing and the occasional repair is cool. But after 2 weeks is annoying awfully fast!!

Any help would be welcomed!

Sadly this is a problem with this boat and the widowmaker. Both boats share the same motor and esc and that esc has a HISTORY of burning. I would contact Horizon for a free replacement, but I would use it as a back up or sale it on ebay and grab yourself a seaking esc for reliability reasons. I think the problem has something to do with the switch for lipo/nimh or so I have read. Either way there is a long slew of problems with that esc... Happy boating and welcome to OSE

Why buy a Turnigy/Seaking from an oversea's vendor and pay large shipping when you can buy this stout 120a swordy for 69 bucks from Steven here at OSE.

I had that boat and the widowmaker and so far no problems running the stock esc?
Sounds to me like you over ran the boat 4500 ten min run do you time your runs? I run my widowmaker with the same motor esc with a 5000 lipo and run it for 7min no more and that drains the lipo low enough.
Don't push the boat running that long it's probably over kill and you should never run the lipos in the boat untile the esc's cut off comes on that's to low and if you do this alot your lipos won't last long.

Im not new to the rc world just the boating world, and dont over drain my lipos they are too expensive not to take care of. And those 10 minutes werent high speed full throttle either. And after doing some research on the Diesel is right there are so many reports from beginners to seasoned boaters about the unreliability of this esc.

As for getting a esc , I have a source in the USA for seaking esc so thats not a issue. Very nice esc in the link though , just way more than I need , and probably way more than the boat can handle.

Anyone have any suggestions on trying to repair or clean up the burn damage inside the hull , didnt go all the way through the inner hull , but sure looks nasty and smells worse!!!

[SweetZ28]

Well that was the problem... you should never just cruise around with a boat they are not like RC cars if you do this with a boat all the electrics heat up very fast... with a boat you kind of want to always have it going top speed without alot of throttle fluctuation as possible and it will run it's coolest.

and the ESC send it back to horizion they will give you a new one.... call em first.

Everyone that has posted in this thread has offered valuable info. Deisel is right about the escs, but z28 is correct in saying that limiting your time is a good idea. Heat will build up in electronics and even the nicest setups can get hot if ran long enough.
Boats are a world different in cars in that the load is so much greater, making the current draw a lot higher. Its really not even comparable.
As far as lipos, if you are putting more than 80% of the rated capacity back into the battery when you charge it, its over-discharged. So with a 4400mah battery, it shouldnt take more than 3500mah to charge. Overdischarging may have a lesser effect when just running cars because of the lower current draw, but you will start seeing a difference in boats. They are harder on lipos and much more sensative to lipo quality.

Now on 1 of the forums, someone ran across a lipo limit gadget for .99 cents where 3.3 is shut off limit where a horn goes off to let you know.

With newer lipo technology, the Low voltage cutofs dont really work. My lipos are discharged at 3.6V/cell.

Well much thanks for all the help , ran into a guy today at the park who has a supervee 27 brushless , talked with him a little bit. Said the Supervee is a much much better boat , while the downside is running a dual battery setup and needing a LVC if you use lipos. The electronics are so much better , he has never had a issue with his esc or motor. He said they do get a little warm but never overly hot.

So Ive considered just parting out the good stuff from the shockwave and investing in a Vee , found a few nice used ones online very reasonable priced!

FRED here. I found the low voltage limit for lipos which sounds a horn at 3.3 voltage for 1.00 = 1.69 for postage and bought 2 of them. ebay----seller ouyou2010 (15776 ) 7.4-14.8v RC lipo Battery low voltage Alarm indicato 130497915967- Price US $1.00 - cost for 2 is $2.00 + s and h $3.18= $5.18.--- Now for one is 1.00 + $1.59 s and h = $2.59. LOL- It says i saved .20 cents on shipping from ouyou2010.
