Actually GG if I fitted the 62 disguised as something smaller, I'd probably just dig a bigger hole in the ground than I would with a 52. It was not my idea to run an over-sized engine, just that of a perfidious compatriot on an English website!

Talking of which I've just had a couple of flights this afternoon with "Boris," the Baron which I finished in Russian WW1 colours for last year's event. It flew well and drew some appreciative comments. The Magnum 52FS is running well.
