Hi there. I just thought I would give my 2 cents about this great plane, that is great for an experianced pilot. I have had 2 Northstars and soon to be a third with a D/F on it. The best thing I can tell you is to balance this bird RIGHT ON THE C/G from Laddie (the plans). Also as far as the engine goes I had the best results with a Tower 46 and a 10-8 Master Air Screw prop. My bird turned out at 5.5 lbs and really screams. I tried other combo's and that engine prop works best. I moved the servo bay as far forward as the height of the servos would let me and this greatly reduced the nose weight needed, I then added a fifth servo (dual aileron) Now I have flapperons.

There is a lot of different engines out there. The best thing is to build a strong and light plane. If you are not into really tweeking things and are not comfortable bashing then stick to the plans. More engine = more weight which means you need 4 times that ammount in the nose to balance. Remember an 11" prop is the max.

If you want HOTTTTTT and can afford it the very best 9thrust to weight and rpm) is a JETT.46.
