brilliant thanks

 

old gpm divided by engine rpm = multiplied by new rpm = your new gpm

26.26 gpm divided by 5000 rpm =0.005252 x new rpm 5350 =28.0 gpm with out changing a pill

so by removing weight from clutch causing rpm to increase @ the step lets say 35 grams = about 250-300 rpm
it will tuner right up & keep the fuel curve pretty happy , but will sometimes cause severe lifting of frt end and or spinning of rear tires this applies to most nitro applications
