you should be fine weight wise =)
try balancing the plane back a bit more with some weight on the tail in tiny incraments. See if this helps any. What about playing with different props? |

To post pics just scroll down to MANAGE ATTACHMENTS. It is pretty easy from there.

Yep! Thats the ones I have a whole case of them. I am going to use them for projects for my CAD/CAM high school students. A step up from the mouse trap race cars we just finished.
Anyway, Nice pics! Glad you got it figured out. Do you think 16 year olds could make a bump? |
