Just bought myself a second hand Corby. General concensus is a Magnum 70FS is the motor of choice so will have to chase one up. As my Corby is second hand, I don't have the instructions so am wondering if someone can tell me the CG position. I do fly off water, we have a large dam we are able to use in the next paddock beside our flying field, and the idea of the Corby on floats really appeals!
