am i the only one running gms?
mine works great (gms .47) go to the field hook up the starter and away she goes.
the engine is a piece of cake to tune, im a noob at tuneing but have yet to have a dead stick in the air (running coolpower "pink" 5%nitro)
the gms is cheaper than the supertiger and a hair more bhp.

gms produces 1.47bhp
