    power to weight ratio

    I am just preparing my self to enter the world of 3D. I am looking at the great planes 27% Cap 232 12.5-14lb plane. I have read and heard that you need a 2:1 power to weight ratio for you engine. This means that I would need an engine that produces 28 lbs of thrust. that size of engine would not fit on to this size of plane. is it true that you need a 2:1 power to weight ratio for true 3D manuvers?

    Please help me resolve my quandry.

    RE: power to weight ratio

    2 to 1 is great, but if you only have 1.5 to 1 that is fine. 1.25 or less and you basically are above 3/4 throttle to hover, which does not leave a lot of margin in the wind if you are 3D'ing close to the ground. I've been there.
    Best of luck.
