It is cheaper to operate than any 140 setup-and costs less -
also italso has far more power - no needle valve fussing - a wooden 19x12 prop - it is quiet -
For those who really want a 2x2 mm plane that is easy to do and inexpensive and reliable - try this approach--If you have no idea as to what airframe to use - just copy the new Predator by JR Models - or any similar airframe .
Mine is std foam wings -and a light wooden fuselage - the only carbon fibre is the wing tube.

You don't have to believe it - but the quiet planes around here , are the gasoline models - with very few exceptions.
