I'm trying to figure out what pinions to buy. Rightnow I'm running stock 53/59 spurs and 17/23 pinions. The track that I'm running on is small with a small sweeper. I want to keep the stock spurs since I have so many of them but would like to change the pinions so that I will have more kick. Is that considered gearing up or down? What pinions should I go with.

M run 16/22 at HT and run 17/23 in South Austin and 18/24 at the SWS. That is what I was running.

If you need anything give me a call at the shop.

I don't run at your track, but you run these changes in the pinions and leave spurs stock? Have you experience any gear stripping?

HarKonnenD, I see that you mention in the post above about stripping gears, is this a problem with the mtx4? The reason that I ask is that I have a friend who is having major problems with stripping second gear he has tried every possible solution he can think of and it still strips them, Is there a reason for this that you know of?

Some said it was due to people running a high difference number between pinions and spurs, engine mount shifting, or that 2nd gear mesh was to be set first instead of setting first gear. Other people never had issues like this at all. Here's a great site I was recommended to as well as others about the MTX4. :tire:

Hey thanks Joe Maxey. HarKonnenD, when I first got the car, I was always stripping 2nd. I don't know if I'm just doing a better job at setting my gear mesh or if the one-piece engine mount is helping; but I'm not stripping them any more. Also, after every run, I look at my gear mesh to make sure it has not changed and tighten down the screws that hold the engine in place. I plan on running my TZ this weekend with the original engine mounts. I'll let you know if I start stripping gears again.

I have seen a few Brass and other metal battery trays here and there but never have actually seen one for sale on a web site. Anyone know where I could get one? A CNC aluminum tray would be nice. At the WinterNats a few weeks ago my car was very close to being to light in several qualifiers so I was thinking if I had to add weight I might as well add it to the lowest point of the car.

one piece engine mount
 

Hi guys,

I´d like to know what one piece engine mount you guys use or recommend. I´ve read that 3racing products ain´t good, but what about their engine mount? Yeah Racing has one too. I don´t know if Kawahara make this engine mount.

No.

try WWW.skylinercracing.com for some hop ups.

how much does that tray weight?

Has anyone tried the mugen new steering blocks? I did and I noticed that it steers more smoothly at sweepers especially exiting. Does anyone felt the same way with their cars?

anyone know if the Kfactory tit pivot balls made for the MTX3 will work for the MTX4? If so, are there any differences in quality compared to the Mugen ones?

As someone else stated, the skyline mount works. The Kyosho one-piece mount for the RRR is a very high quality one-piece mount that works in the MTX 4.
