I fly 1/2a, and the other morning it was "too windy" I went anyway, the 1st flight was hairy, the 2nd went into the ground from my hand, the 3rd was too scarey,,the engine cut out after about a minute of battling my plane around, man was I glad to hear that motor die...its a 1/2a .049 engine no throttle, rudder ,elevator only plane...the tank only lasts for about 4 minutes(ie I can only bring it in when it runs out of fuel),,,,I could only hover forward,,I actually had to dive to move forward at full throttle....Foam wing, blow molded fuse (much the same as a kids plastic ball bat) simple stick type, I guess you'd call it......... you couldnt have flown a .40 trainer in that wind...I use a 16oz fuel bottle to fill my tank, it was about 1/2 full and it blew off the table when I was starting my engine...Rog
