I have been appointed an Australian agent for Mega aircraft motors! All sizes available!
Mega have been producing quality motors for some time. Their inner-runner motors have been popular in the past, and now thye habve developed a range that suit the current needs, and for trensing F5J events.
Being inner-runners, these motors overcome all the problems of fitting a motor to a narrow glider fuselage. There are no external miving parts to worry about. The ESC connects to cables that come out of the back of the motor.
The folllowing motors have been engineered to meet the needs of ALES events (like the Millennium Cup) and F5J events. Check them out and see what suits your requirements.
