This plane with a .46 would be very very under powered. You would have to build it very light. I wouldn't do it. I would put a good .61 in it. You can get a good used one in the sale forums for not a lot of money. It flies great on a .61, but I would not do it on a .46. It would not be worth flying if you got it in the air. It would have no vertical, and would probably have to dive to build speed to do loops. If you pulled up too steep on take off, it would likely snap. I wouldn't advise it.
