yea, dolanosa's price estimate is about right, or maybe just 20 or 30 bucks more to go with the good phoenix controller, and thunder power lipo, and yes, the 25 amp controller is enough, i just like to go way over on the controller since the all up weight will be almost the same and you get less internal resistance giving longer flights and longer lasting parts.

also good point about the wings, i forgot to mention that i did reinforce the wings on mine with clear packing tape, a few strips on the top, and a few strips on the bottom, full length of the wing, it makes a big diff, when you see what this plane does with the upgrade youll see why its a must the strengthen the wing, i think without it the tape, the wing would break. other than that the rest of the structure seems to be holding up just fine.

i did also have to relocate the battery about 3 inches farther back to get the CG right, i just cut a new spot for it, then glued a couple pieces of balsa cross ways over the hole that i made to make up for the support foam that i cut away, then added a loop of velcro to go around the balsa and battery at the same time, to hold the battery in place.

if you decide to do these upgrades, let me know and i will get pics of exactly how to do the mods, since i already have it figured out.
