Hi
I am building the ultrafly extra 300s which is now supplied with ultrafly's b/06/10 motor (no gearbox) the kit has no instructions for mounting this it only has the ones for the gearbox motor, anyway it looks reasonably simple appart from the shaft doesn't come out of the front of the motor and it should be fitted with a prop adapter (supplied) the shaft is long enough but sticks out the back of the motor not the front? at the back of the motor is a circlip so i can't just push it through, anyone built one of these yet??
