anyone notice that the black belt system makes more noise than say.. the stock one? I recently changed over and i seem to be getting a high pitched sound at higher speeds.

i say belt because its the only thing i changed, could it be somthing else? my gear mesh is the same as before

I honestly havent touched a 48 pitch gear on a sedan in almost a year now, 64 pitch is much better for fine tuning. Just try to get the same final drive ratio with your 90 tooth gear as I got with the 128/30.

My car is very quiet with the black belt, and I havent used any grease or anything. Check to make sure it's not too loose and rubbing on the tunnel too much.

What do you guys think is a good digital servo for TC racing? Anyone know which Airtronics servo the team drivers use?

James Nguyen

Either the 94357 or the 94452. 357 is faster but the 452 is slightly slower and easier to drive with.

I think they use 94452 but not sure

I use a 94758 and I like it I also had a 94357 and it was also good !!

James Nguyen

A lot of the mod guys are using the 452 now but for some odd reason airtronics just discontinued it.

I like the 357 personally, if it's too fast, just turn the speed down on the radio. I generally like the car a bit on the twitchy side though.

For the budget racer i'd use the hitec hs-5925mg. It's fast, strong, digital, and about 79.99 @ lhs. I'd like to start using the KO Propo pds-2343 but I don't have that in the budget yet.

I've had a lot of problems with Hitec in the past, in fact one of their servos stopped working conveniently at full throttle on my 1/8 scale buggy on the straight. This is after I bought a Lynx 3D that wouldn't even transmit a signal. I wont use them for anything anymore, and for just $30 more than that $80 price you can get the 357 and propably never see a problem.

I've got the same 357 in one of my cars that I got 2 years ago and it works great. I run them in all my cars.

i used the 357 in my xxxs, then my tc3, now my b4 and xxx4, and its soon to be the stearing servo in my 1/8th scale, i love them, and like randy i like a twitchy car, alows me to throw it thru bad situations more

Can someone please tell me the weight difference between the graphite + and the plastic chassis, with everthing except electrics in it? My car(plastic) weighs 1589 grams with everything in it.
