If you wanted to get crazy power, look at the tower .75 two stroke.. about 95 bucks and it is a killer engine.. I have one on an Ultra Stick .60, and it hauls that thing straight up like a homesick angel..
Even the tower .60 would be a good choice..
I have not heard much about the tower 60, but there are TONS of folks on here who have had great luck with the tower .75..
P.S. on second thought, it looks like that plane has a wt. of around 6 pounds which is what my Stick weighs.. So it wouldn't be "crazy" power, just a tad more than ya need.. Never a bad thing!
