I have one of these that my neighbor gave me still set up for electric. It was originally the 3 channel version but he installed ailerons but said that they needed to be redone because they didn't seem to work too well. I have a like new Thunder Tiger GP15 that is going on mine. I'm almost finished redoing the aileron setup. After that I'll recover the wing, install the radio gear, engine and fuel tank and get her ready for the maiden flight. I'm also debating whether or not to make it a tricycle gear setup. I'll have to see what the AUW is when I'm done. My neighbor has 2 more that are glow powered. One has an O.S. 25 LA and the other has a 15 LA. He says the one with the 25 is a rocket and the one with the 15 is more relaxing.
