I have a buddy that got an aircraft replaced and he had a BME102 on it, so the warranty is a non issue.
I have the zdz80 on mine, its under 25lbs, and performance is very good. I would like to see that 75 powered one go, Being heavier with a smaller motor its probably less performance than mine. Have any video? It may have more vertical than you can handle, but wait until you want to do 3D.
Here is a video of mine with the zdz80 on a pro zinger 26x10, I have since replaced the prop with a Menz S26x10 and performance is WAY up.
BUT, IMO, I am still putting a DA100 on it for more power.
