You may try the carbon shaft upgrade its lighter. Some prefer the stock aluminum shaft for low turn motors since its more durable.

Yeah i've had to replace a main shaft before. It was an old and battered item. Scored horribly from the servo ears and from various wires that rubbed it.

Some good long hrs of use with a novak ss5800, and then a GTB 5.5 resulted in a shaft that was wobbly and caused vibrations. Even worse, the pins on the end did not line up! (looking down the shaft) The actual shaft itself had gained a twist. Talk about power...

so in went a new one and some alu centre drive cups. Very smooth and wobble free now.

So your using the HPI cabon shaft and aluminum center cups now? How does it perform on lower turn motors? Can it handle mod motors 12T and below?

correct.
the CF shaft is ideally for stock or 19t racing. very lightweight and improved acceleration.
stay with the stock aluminum shaft if your racing low turn mods.
from my experience even with lowturn mods...mine developed a wobble
after a few runs. so keep several backups in your pitbox.

Huh?... who said carbon? LoL...


no the new shaft was another alu number. I didn't think the HPI one was rated for anything below 12t? .. did someone throw that number around?
I'd love to get a whippler one, but to be honest it's not something i need.

besides, i have a sapre alu shaft as well b/c rc model took 4mnths to send my shaft. I got one locally instead. not much use 4 mnths later is it.. that's ALOT of missed races...

I have been making/selling a carbon fiber drive shaft for the HPI Pro 4 for $35 shipped anywhere in the US. A similar shaft I made for the TC3/TC4 has been tested with mod motors as low as 8T and foam tires without any damage. As the Pro 4 is more durable in terms of fore-aft flex than the TC3/TC4, it should hold up just fine. Click on the link below for a few more details.

I still have one or two more left in stock and after that I will take orders for them during the spring-summer months. If interested, send me a PM or email (ewippler@hotmail.com).

Thanks. I just bought a Novak 4.5 brushless system. Would this carbon shaft withstand the speed of the 4.5 motors?

I think what he was alluding to, was that it should be okay. Seeing as the pro4 is built better than the TC-4 you should be right. Then again, there are no guarantee's in this business. No matter how you put it, a low turn motor (eg. 7t or 4.5R) still gets up some serious shaft speeds.

The Stock alu shaft can still sometimes bend.. but if i was a US resident then i'd prob. give his shafts a try.

I have the wippler carbon pro4 shaft and it is rock solid. Obviously with Carbon if it bends in a crash it will go back to shape unlike aluminum


Anyone seen the Square front shock tower in stock anywhere?? All my usual sources are out of stock

A picture with your post, when trouble shooting, will probably get more rctech help than without...
