Just keep in mind that the FireBird only has 150oz of fuel capacity. With the larger Turbines and high speed flight you will have a short flight. I think 35 -40 lb thrust range is good for this airframe. You will have no problem hitting 300mph on 38- 40lbs. Also if you have never flown an airplane that fast you better make sure you have good eyes.. It gets out there really, really fast......
