RE: starting up an .049 engine
Underaged Pilot,
The good ol' PT-19 Control Liner!!!! That was the plane that lead be down this path of 1/2a flying and was my first plane at age 12. While it was easier to just fy off a hard paved surface what my buddy and I would do is lay out 4 or 5 pieces of ply wood, sheetrock or what ever we found in our dads' barns and used it to take off from and made a low ramp at the end. Your right the PT-19 is just to heavy to hand launch.
Also DO NOT use an electric starter on the stock engine. You will grind the front end of the crankcase down and push the crank into the backplate in short order if you do.
Later,
Tim
