Zinger 22-10s were doing about 95 mph on our T6s in 1992
Current T6s are going about 120 mph with the exact same planes and engines using the APC T6 race props..No other changes...
We pretty much know what works on G62s after racing for 19 years..
But nothing was ever said by the OP about this being a racing application. Racing props and sport / warbird props are completely different animals.
