Do a search here, and you will find a ton of info on this fantastic plane. Keep it light and it's a gem. Not much of a 3D machine, but does Imac beautifully. Keep the elevator throws in the recommended range for the first few flights. It flies best on a 1.20 to a 1.60 size 2 stroke or a 1.50 to 1.80 4 stroke. I don't recommend using the stock 3mm pushrods. Build yourself some nice 4-40 rods.
