Jim, the OS 1.20 4-sroke also works well. Mine has unlimited vertical and keeps tractoring straight up even after a lively snap roll. I mounted mine at an angle per the GP motor template, but I like Don M's inverted mount with the inside header and the flex pipe. I would have done that had I seen it before doing the angled thing. The inside header and flex pipe are going to add a few shekels to the cost, for sure, but it would be a nice winter project to get the parts and a new cowl to do the conversion.

Yeah Jon that pilot figure must weigh 2-3 ounces -- insane!!

I also upgraded to the CommonSense RC rx battery, the 2000 mah 7.4-volt lipo with a voltage regulator. The whole shebang weighs about as much as a 1500 mah nicad hump pack. I have checked it very carefully a couple of times and can get 10 flights per charge (analog servos, absolutely no stalled ones), and can recharge in one hour if I still haven't had enough for the day.
