hi I would like to build a reve limiter on my zenoah G26RC1, its stock with the magneto flywheel and has the kill switch buton to turn it off

This is for drag racing purpuses what I want is to have a really high rpm engagment on my clutch an be able to reve up to a disered rev limit right before the cluch engages and then when I launch just turn of the rev limiter to lauch at a higher RPM.

This is what they call a Launch control in the Super FWD Honda Drag Racing World. have any of you seen anithing like this or have an idea on how to build a unit like this on, it shouldent be dificult as the cut its self will be controled by the same cables on the kill buton

thanks
