oh yes. i forgot about this
ive switched to a a35 cdi box, and flywheel.
differences ive noticed is a little less low end, but a increase in top end speed and rpms.
here are pics of the stock a55 ignition
note the raised piece of steel and the trigger that reads rpms.
whats great is the cdi advanced automatically in the low end for more power, but automatically retard in the high rpms.
its a good/reliable system, but lacks if you want a top speed.
go a35 or HPI
what you'll need from the a35 motor, is just the flywheel, and the Cdi Module
hope this helps~SABAT!
