well boys we upgraded or 23 cc standard redcat engine and put a Darksoul cylinder head on and change piston and went racing this weekend/ today and we ran rich on half tank of fuel a nd striped main clutch gear off the clutch drive
but on the happy not it flys
we just need our metal gears to stand up to the treatment
