yea, return it, i used a iron with a cover over it and with the right amount of heat the covering will shrink without wrinkles, mine did anyways, these things happen when they build them in the summer and ship them in the winter, it creates havic on the frames.but as far as the other problems i had none of those, my plane was great and i did use standard servos with good results.

id cut the hole patnjim, you can get the wrench in the front cooling hole to loosen the nut to remove the jam nut and i did mine lots of time without ill results with no locktite or any thread locker except on the end that goes in the muffler to reduce oil leaking and burning onto my pipe.

yes CEEGEE, the edge is great and you guys wont believe me but the edge does the inverted flat spinjust as fast and flat as the do (but wont rise) but it is beeeeutiful im really glad i got one and i love the speed also, my first fast plane[X(]

i also found a good use for those red ucd booties

sorry about those baddd pics cause i am way better looking than that
