bobo,

I've converted a few glow to electric, and used there recommended CG, and they flew great. One of my best conversions was a Sportsman Aviation Corsair, and I used there recommended CG, and she flew very well, with minor trim. With glow yes the CG is going to move forward because of the location of the fuel tank, and the weight of the fuel. But they consider an empty tank scenerio, where you run out of gas and still the plane is flyable.

My biggest concern with a new product that's new is the correct documentations. Most of these planes come from China, and we know the language, and translation thereof can be difficult at times and misspelled, and eventually misprinted. So it is critical to double check there calculations. In this plane, I followed there instructions and it was off by alot.

If you do use a fuel setup with that CG listed of 85mm, when you fill up the tank your CG will be foward, but then when it starts going empty it shifts rearward, and thats when you could probably lose it.

As stated in the other thread, I have nothing against the plane itself, It is a beauty. It's just a pitty that I couldn't enjoy it.
