You guys are really confusing yourselves. [sm=spinnyeyes.gif] Why do you want it make this plane into something it’s not. [sm=confused.gif]If you haven't seen this review I suggest you read it...

The power to weight ratio is the point. How much weight will you have to use to balance the plane? There comes a point were adding any unnecessary weight really defeats the purpose. What you gain in power you lose in control. It would be like flying a brick…you can make it fly but it will be hard to control and even harder to land. My suggestion for what its worth is to go with the recommended engine sizes or their equivalent in gas…a 150 four stroke at the most.
But if you insist in throwing you money away, I'll send you my address and you can send it to me...I'll put it you good use!

Good Luck and Happy Flying! [sm=cool.gif]
