I think it would be neat if the guys got together at a RC flying field and made a
"inertia" starter.It would need no electric battery. Make a flat stand/table too set the airplane on about 2 feet high. On end of stand would be a heavy wheel with a crank. On the wheel would be a starter cup....hand crank on other side. Get the wheel spinning with crank...and shove the spinner on your airplane into the spinning starter cup. You would never need too get your fingers near the prop...and airplane could not shoot forward. So you guys that got some ambition...give it a try ! Capt,n
