Buggy:
BTT engine
6mm restrictor
steel flywheel
4 shoe clutch (2 composite & 2 aluminum)
springs (composite shoe springs BLACK .036 25°)(aluminum shoe springs GREEN .036 30°)
9901 pipe
41021 header

Truggy
BONITO engine
7mm restrictor
aluminum flywheel
4 shoe clutch (2 composite & 2 aluminum)
springs (composite shoe springs GREEN .036 30°)(aluminum shoe springs GOLD .040 25°)
9901 pipe
41021 header

My questions are:
Lighter flywheel has what effect on motor?
Heavier flywheel has what effect on motor?
Lighter spring on composite shoe engages first, what advantage does this have?
Heavier spring on aluminum shoe engages later, what advantage does this have?

I run a RC8.2 with the same setup except a 6.5mm restrictor and a RC8 clutch with all aluminum shoes and 1.0x3 springs and my RC8T same except a 7.5mm restrictor 9853 pipe and a 41020 header and a RC8 clutch with all aluminum shoes and 1.0x3 springs...........
