I took my trusty dremel and grinded the case down a little. No problem adjusting the idle now.

AERO II

Anyone of you guys tried the new Taurus AERO II body from HPI? It's ROAR legal, so it must be not too bad!

Yes, I'm usually carrying alot of momentum into the straight. I run my tires anywhere from 58-60mm and anything beyond that will drop my lap times. I've also played with the adjustment point on the 2 speed. My r40 loves a small tight tracks though. All I need is just a hair more top end to give me the confidence for big tracks. I can remember seeing a 22 tooth some where, oh well I have some researching to do.

Jeff B- Let me have your gears!

You can use the kyosho fantom 22T or the mugen 23T I think. My strategy is usually run newer tires (62-59 mm) on the bigger tracks. I know the G4 had no problem at Cincy last year and it's top gear ratio is 4.86, vs 4.93 for R40 and 5.05 for mtx3. The longest straight I have to run is Cincinnati at 270' and the G4s had no prob with that last year and they even had undersized tanks.

I tried the electric one on my Tc3 for carpet season and it was OK, it felt fast down the straight (is that why it's called aero). Maybe I 'll throw it on tonight and compare w/pf alfa 2.

I'm leaving Atlanta tomorrow. I should be up there Wed night. I'll try to make it to dougs on Thur and Fri, but the weather channel is calling for isolated T-storms.

Default Adjusting Clutch?

I just finished building my R40 and went to test it out today. I noticed I have to rev over 1/2 throttle to get the car moving. How do I adjust the clutch so that it engages earlier? Thanks

Its some way u can just take a small alen screw and stick it in the hole of the clutch bell. Or you can take off the clutchbell and loosen up the thing that holds down the screw.

Try decompressing the motor slightly with shims. It works wonders and keeps your motor cooler on larger tracks.

Ummm, the lowest gearing on the G4 is 4.66 with the 25T/46T combo. The 4.86 FDR that you're referring to is using 25T/48T combo. That's probably the reason why the G4 does not have problems in Cincy.

Amg you are right about the motor running cool just by adding shims. It's also easier on the plugs.

Proteus I will see you at dougs on Friday. What time will you be there?
