Well based on the claimed weight of that plane as under 4 lbs the LA46 will be plenty of power for that plane, i have an OS .40la and while not very powerful i think it works good for sport planes around 3.5lbs or slow type fliers up to 5.5lbs. My .40 on a 11x5 prop was turning 10500rpm which by the thrustHP calulator is 4.84lbs of thrust and .605HP, the .46 will make more power so if the extra comes out around 4lbs you will have a good setup, the LA was my first engine and i will tell you it doesn't get any easier than a LA engine.
