RRP failed me!

[rcmedic]

I was doin some light bashing with my wraith. I have a tekin sc4x 7.5t in it(love this motor!), anyways i was jumping a little ramp and next thing i knew i didnt have front wheel drive. I picked my wraith up and saw my mip driveshaft hanging and my upper driveshaft spline gone. I looked arounf the parking lot and found it with the pin still in it. This is what i found...

I've see this happen before. The main reason I still run the stock drive shafts. I rather them break than my RRP one piece bottom gear.

Yeah I have heard the same story!! I hope mine lasts a little longer. I am using only 2S with a Tekin RS and Redline 13.5T motor.

Thats the thing, 8'm going to a tekin pro4 HD soon... And that is 3500kv 4pole 550 on 3s

[wildmanMG]

I'm running a Pro4 3300kv. I haven't had mine break yet. I would try to contact RRP and see if they might help you out.

Sent from the foot hills of Tennessee.

Got a buddy that has twisted and bent 2 of these. One of them just driving in the yard. I don't think RRP will be wanting to replace it but keep on them and they should. I know they didn't want to replace his.

Or contact supershafty.com & get...



Chromoly Extended outputs up to 8mm!!!
Broke a couple of those just like the pic shown.
This trans is nearly bulletproof!

Just imagine what would have happened to your stock diff... LOL

You're pushing the envelope ....expect things to break

[rcmedic]

Just broke the rear. Thats a 2 pole brushless motor doing that! I was driving around in my loving room not even going fast. Just putting around and the rear shaft fell out.

I piece bottom gears, meh.

Get a good quality steel gear and use a better output like SuperShafty or stay with a stock output.

Carpet crawling is not good for your drivetrain. There is t much 'give' on your traction.

[Lentsnh2012]

SuperShafty or the outputs from Crawler Innovation.

I have the outputs from Crawler Innovations put up against a 6900kv Castle 4 pole motor and a Mamba Max Pro and MIP driveshafts. My Wraith probably weighs about 8bs with a 5000mah 40C 2S lipo in it. There's no telling how many times I've "bumped" a rock trail and doing a full throttle landing.

Why would you want to run Any output shaft with a hole in it? I know it was made that way, but anytime you put a 2.8mm hole in a 5mm shaft your asking for trouble. Just get the Scx10 Rpp outdrive without the hole, locktite a 3mm setscrew in there and never worry about it again. Just my $0.02........

It makes sense, but the way I'm thinking about it, when you just have a set screw torqued down and locktited on, you still have the possibility of it becoming worn on the bottom side of the set screw (just from wear). Whereas, a screw pin, you have a bigger contact point and the set screw is spreading out the load caused by the torque.

It might sound like I've had wayyyyy too many tonight (I have had a few)

We used to snap those like crazy too.

Beefy = better

I like a through hole design, no chance of driveshafts spinning or popping.

I got it back sometime ago. But it looked like to me, and alex chen that they had welded the ended back, re lathed it, and drilled back
