wohoo - finally my first post on RCtech

Let me jump right into it: Is there a trick how to properly mount the pinion on the slim shaft with this brass insert they give you in the kit? The pinion always comes loose with the LRP Vector Micro Motor I'm trying to use. It also has the a slim shaft, so I need to use the insert... I don't get it to keep the pinion fixes though

Hey welcome Don!

I've not encountered slippage on the Sport Tune380 so I can't say. Your LRP motor is high output (6900kv) so I bet the torque itself just causes it to slip.

I don't need that much power so I use a HobbyKing S2838 motor running 2S. It's 2800kv output and still quite fast running a 15T pinion (much faster than the SportTuned 380 motor, faster than a 21.5T FWD m-chassis). It uses the 3.17mm shaft, so no sleeve adapter needed. And the motor fits without modifying the steering linkage.

Some people use a piece of antenna tube instead of the brass insert. HTH

Use some retaining compound like the one sold by Loctite for retaining bearings on shafts and such.

That's a good idea. Is this product removable? Not that I need it, just wondering.

Got around to making a front upper camber arm for the front. The solid plastic rod was bothering me as the camber setting was too aggressive for my liking even with the longer "A" rod.

I used 2 damper ends with one of the two trimmed off by 1mm, used a 9 or 10mm set screw per side. I now have adjustment from positive camber to the "A" rod length. I'm currently using -0.5 degrees.

Yeah, it's just going to be a little bit more difficult. But it's not going to come loose on its own at any rate.

Thanks for the info. I'll keep this product in mind if I encounter something like this in the future.

Decided to run 55mm Shimizu's instead of the Tamiya D60's. Also lowered the upper deck back to stock height, removed motor fan, lowered body, 3.5mm ride height. Blue springs up front, White (?) stiffest springs on the rear. I also shortened the damper throw.

Very grippy and fast on my track. ..

Little dirty from all the tire dust on the body..

Woo-Hoo! Just ordered a TA-05 M-Four. Late night impulse purchase. Couldn't pass it up though as I'm not sure how much longer they would have these in stock at that price. They are going for about $100 more and up on ebay right now. I'm such a Tamiya fanboy.



Looking forward to getting it now!! Will probably be picking your brain sakadachi here in the near future.
