ok that's right I bolted mine on as well ...the engine should be powerful enough...not sure changing the prop would have any effect.....im guessing here but its either not powerful or too much drag......I would have to see it ......is the rear axel in line with the aluminium spar or further back towards the engine...it looked right in the picture...it sound that it cant rotate for some reason........lift....thrust.....drag......weight......the front opening on mine is about 2i to 3 inches deep gauze.....I assume the wing inflates but cannot rotate..i also had large wheels oh yes try flying her with out the body first..just in case...j
