RE: world models ultimate .30
Mine has a .52 Magnum fourstroke, and it's a nice plane. I can stick it in the back of the SUV, assembled, pull it out and fly it, even in the winter. During summer, I prefer larger models, but this one has always been dependable.
I have posted in at least 3 threads about this plane, so I know you can find that many threads with a search.
This plane would NOT be good for your first venture into glow, unless you've been flying taildraggers that rise off ground and land fast, in whatever power configuration you've been flying. The plane is very NIMBLE. That means, for the inexperienced, it's unstable. You have to fly it every second it's in the air.
Good luck,
