I have a commander. It's hit the ground in an adverse manner more times than a frog's butt, and it STILL flies...rather well, i might add.

All i have replaced is 1 propeller, and one wing (even though I learned how to fix the wings).

The wings will fold up- but they can be fixed. Cut a piece of coat-hanger wire about 8" long, place it across the crease, and tape it in place with some GOOD (i.e. 3m) packing tape. It adds some weight, but hey, it still flies ok (go figure).

Also, you can extend the control surfaces on the stock commander v-tail- just cut the control surfaces on out, and use a piece of packing tape on each side to join the pcs. together and act as a hinge. Works pretty good.

The prop damage is easy to fix- just put some packing tape over the damage. Or don't, since it don't make the plane fly any different (really!!). Yesterday my wing gave way and folded up during some of my acrobatic attempts and NOSEDIVED HARD from about 200 feet up....no damage. None. Unless you count the dirt wedged up in the nose

My canopy come off a long time ago. I just left it off (heck i dont even know where it is!) and rubber-banded the battery pack in, works just fine. Canopy or not, make sure the pack is rubber-banded in, because if it isn't, a hard nose crash will make it pop out (possibly taking the wires and circuit board with it).

I can fly my commander in a 100x 100 area at less than 10 feet of altitude, if i want. it's easy to control after you crash 1,239 times, and figure it out.

But for what it's worth, it IS harder to control than my PT40..
