Just bought a Pica 1/5 scale Waco ymf-7 kit from ebay. What would be a good engine to use for this biplane?

The RCV 91 CD will fit totally inside the cowl

One of our club members has this plane/engine combo. He gets very 'scale' performance which is exactly what he wanted.

I've seen them fly with 120 4 strokes and G23s. Flew well with both.

I'd recommend a g26,a friend has one with a 180 saito in it and it flew good although it was a lead sled . He bought it second hand and it weighed 18#'s,it needed nose weight so you might as well go with the heavier engine.

Best of luck, they're nice planes.

Thank You. From what I've bee reading I think the new g26 will do fine. Thanks again

Mine uses the OS 106 twin. It fits completely within the cowl, and the power is excellent. I'll post some pics for you tonight.

Moki 1.8 or 2.1 is a good choice for this plane.
