RE: Going from electric to gas
I'm not trying to tell you what to do, just offering my opinion(for what it's worth). The glow fuel powered plane will be alot faster it will take more room to fly it if your not used to flying it. If you had one of those "oops,oops,oops, whew ...ok i got it now" with the electric the "oops, oops" will happen alot faster, maybe not giving you enough time to say "whew...ok i got it now" with the gas plane.
If you have someone available to help you it would probably be a good idea just incase you got into trouble.
If the megatec gave you the bug...your going to have the bug real bad when you fly glow fuel.
