It didnt come up very well after the run in its a little loose , its got a lot of taper on the cyl and too much exhast timing and also sub piston induction that I dont want , I will fly it next week in the same model as my No1 Silver Swallow and see how it goes

its out to about 1.8 cc 's with a long crank like the first one and the 11mm longer conrod made it heavier

Its got a bigger counterweight in the crank shaft
