I started this thread, and flew my plane with a tower .46 untill last weekend. It always took the whole runway to get airborne, and seemed to bairley hop into the air right at the end. I found I had to keep it wide open, or close to it to keep it airborne. As soon as it broke ground which required a large amoung of up elevator you had to level off and build up speed. The plane seemed to have a tendencey to stall on take of every time. I think with the right motor this plane would be great. I have the Phoenix Sukhoi and run a Tower .75 in it and love it. Jumps off the ground.... I wrecked my Giles sunday, but I already ordered a new one, and am planning on running a Magnum XL80 4 stroke in this one. If you compare price on this arf, and its good quality you really can't beat it. I gave my last model pure hell. If you had a smooth paved surface to take off from you would have no problems with the .46 in it, but with grass you really could use the extra boost.
Mudbug1001: I ran a slimline pitts muffler on this plane because the tower .46 pipe is way to large. Tower sells them I think around $30....
