Right engine for Extra 300 (.60)
This thread spans from another thread on which the subject came up. I want to know the best engine to fit into an Extra 300 (.60), probably the Goldberg or the Great planes. I have thought about:
O.S .75 AX
O.S .91 FX
Saito 1.00
Zenoah 20cc
O.S 1.20 Surpass w/o pump
Any other ideas are welcome.
