New ShockWave 26 Brushless

[ALD]

Stock prop 1.34 inch x 2.06 pitch+2.760.
y535 Pitch=2.125. Less pitch than stock prop.

I know for a fact that the drive shaft was bent because I had taken the boat apart before running it to grease the shaft, rolled the shaft on a glass counter. it ran but was noisy.
as far as Horizon is concerned, parts are cheep so i don't really care

I used the 3 blade 435 for 12 min with no heat on 7.4 lipo 25c. Everything work good with this set up, but very noisy going to check the shaft may be bent too.

Did you have any heat problems with the motor or esc? The 3 blade prop that you use is it metal?
Thanks for the info

Hey Guys,

Just thought I would post since I am new here. I also have a Shockwave 26 brushless:






I am running a y535 prop being I went through 3 stock props in 3 runs (not even full runs)


Looks like maybe I should run something else?

Also, if my shaft was bent would that cause the motor to move up and down when I turn the prop on the boat? because when I turn it by hand the motor will go up and down as I turn it...

I am having an issue with removing the shaft, the back set screw on the motor coupler will not come out and I emailed horizion and they told me to use a soldering iron to loosen the thread lock, however it still will not come out (got the front one out finally after heating it, but that doesnt help me any to remove the shaft) so the back screw is stuck and now stripped from trying to remove it so I am waiting to here back from horizon on what to do, since I cant get the shaft out to grease it etc...

Sounds like the shaft might be bent anyways, so I will need to replace it..where would I get one?

Boat ran a GPS verified 26mph with 4200 NiMh battery..hoping for more with lipos..

I used a y535 metal prop on my shockwave 26 with a 2s lipo and quickly smoked the esc. My boat was brand new 2 weeks ago and had a bent shaft and spun the blades of the prop just like you. So when you move to lipos( do not use the y535 metal or you will smoke the esc) Look on the forum they will tell you that prop is to big. Easy way to remove that set scew is to use a drill. Then you will be able to remove bent shaft. The motor will move somewhat when spinning prop. You need to loosen all motor mount screws and spin prop to adjust motor screws to minimize movement. I installed a new shaft and never did get all of it out. Call Horrizon hobby and they should replace props and shaft. They have great customer service but the boat is of poor design/quality. I have just purchased a 25" prince from Kintecracin and will use the radio/reciever for it along with the servo.
I will retire the shock wave, not worth upgrading. Lesson learned. Part of the hobby.

Well Crap, this was my first boat (new to R/C and decided to get into boats) and I guess I shouldn't have bought it.

I have no money to "retire" it and get something else, as I figured this boat would be good when I bought it...guess I will just have to try to fix things and hope for the best.

If I get the right size prop, (what should I go with?) and a new shaft, and run it on 2s 25c lipos should it be able to do 30-35mph?

[ALD]

Fix the things that are bad and call Horizon Hobby and they should replace all your props and shaft. They did that for me plus 2 esc's. Great customer service. The boat is a good first boat and you will learn a lot. Just about every rtr boat needs up grades. Iwould stick with nimh batts til you figure it all out. The forum has suggestions for prop sizes. I recall they recommend props in the 400 series it your looking to run lipos. I believe with the right prop and lipo you will difinately get 30+mph. Good luck on your info search. The guys on this forum are great and very helpful.

Excellent! How is the speed compared to stock?

[Visual Perfection]

Thanks ALD, I will definately Call horizon tomorrow and talk with them, as email doesnt seem to solve anything very fast.

I just took the boat out before it was dark and I don't regret buying this boat at all...like you said it is a great boat for a beginner and it definitely is fun to drive even on Nimh's.

Just have to get the little problems worked out with it and I am sure I will be very happy.

I also remind myself that this boat has only been out for a few months, so I guess there is always a risk with buying a new to the market product before all the kinks are worked out.

Might have to give that 435 prop a try, sounds like it might be good.

[ALD]

super quick w/2s 25c lipo w/the y535 prop. When I did a hole shot, the boat jumped like a rocket. I gues 30+ til I smoked the esc. Stock blades with this setup would just spin the blades off but was still very fast. I never tried the nimh batts.

[Visual Perfection]

With the y535 i am running my batteries are getting very hot and the motor and esc are getting much warmer than the stock prop...this is all on 6 cell Nimh..

gonna order a x435 prop I think.. the m435 that harry12cars is running is a 3 blade, but I am thinking a 2 blade will be better for this style boat, am I right in assuming this?

[ALD]

I would try the 2 blade. Run for a minute or less at full throttle then the check the motor/esc for heat issues. No heat issues then switch to lipo and check for heat issues. Make sure your lipo/nimh switch is in the correct position for the battery used. If you forget you will destroy the esc.
I learned the hard way and the esc stopped sending power to the motor.

Visual Perfection,
this was also my first decent boat. I have had and driven others, but for the cost and what you are getting I think it is pretty good.
what you are probably going to have to do is cut the shaft off before the motor coupler and just replace the whole assembly. the parts are cheep and available if Horizon doesn't give them to you.

Driveshaft with U-joint:SW26BL $8.99 [PRB3152]
Motor Coupler: SW26BL $4.99 [PRB3156]

and if you feel inclined you can remove the brass stuffing tube and polish the shaft to make it run even better.
removing the stuffing tube is difficult but it can be done.

Well I Can tell you right now the 535 prop does just fine with my 6 cell 4200 NIMH batteries and I can run through the entire pack (about 7-8 minutes) with no heat issues with the motor and esc other than they get nice and warm..nothing that concerns me too much, being the water cooling everything comming from the ponds I am running in is over 90 degrees to begin with..

Now my batteries on the other hand get very hot after the run - which I have been told might be caused by running the pack too low before bringing it into shore?

I am mainly going to the x435 so I can run lipos safely...

I don't want to spend $35 for a balanced/sharpened prop to find out it isn't the right size so that is why I am hoping to be sure I make the right decision, as i have already done it once and got the wrong size...

Thanks for all the suggestions and comments guys and GEO I will probably end up having to cut it like you said, or drill it out like was suggested earlier and then replace those parts. Hopefully Horizon will replace them for me.

And I agree that this boat is pretty decent for the cost of it. I was either going to get the Traxxas Villain EX or this boat and I decided on this boat. I am still glad I got this one just for the fact it is much quicker in stock form (Villain from what I have found does about 20mph stock..plus you have to run two batteries, it has two motors etc..)
