Default GPM Aluminum Knuckles

yesterday I had the chance to run my alu knuclkles for the first time.

No problems all day long and I hit everything on the track because of radio problems.

I shattered my top deck in 6 pieces after a head on crash at ~40 mph, BUT the knuckles stayed on

Beware.... track owners can charge you an extra for 'stressing the boards'.

Regarding top deck. Ouch!!!!

I'm using 0.8 spurs as many others on the thread. Personally I liked them, lesser drag (but more delicate, and you need to pay attention to gear mesh), finer stepping on the gearing and others.

4.53:1 is to me a quite steep gearing, if you're looking better high end, probably a shorter gearing will make your engine and car shine at high-end.

Cool 4 mm chassis

Actually, since the bulkheads, and all attached suspension parts are sitting ON TOP of the 4mm thick, unrecessed chassis, the chassis mass is LOWERED I.E. THE BOTTOM OF THE CHASSIS IS NOW 1 MM FURTHER BELOW THE BOTTOM OF THE BULKHEADS. Since the only mass which lies below the level of the chassis bottom is the portion of the 4 tires and wheels, and since this remains unchanged at the same ride height the the CG must be lower with the thicker chassis.

Mugen made 4mm Chassis that have recessed for the front & rear bulk head, radio mount, etc.. That makes roll center the same as the stock 3mm chassis. Not sure of RD, Kawahara, 3-racing or others 4mm chassis.

WRONG!!!
because if you run 5mm ride hieght with both chassis, the four mm you have raised every thing 1mm higher than the 3mm chassis at 5 mm ride hieght!
