I agree with Bodywerks, the wing loading doesnt work in favour of Gas engines until you get into 50cc class airframes. You are better with more powerful and lighter glow engines though a 1.60 is gonna cost in juice, it eats 2.5oz of 30% glow per minute!! But its one of my personal favourite engines and i wont be without it in 2m (70in.) class aircraft, it just hurts the pocket a little at $10 a flight.
