My OMP little Yak is 1830g (4.007lbs) with a OS .50 SX on the nose. If you're going to be using a .46 on it you can get it under 4lbs if my theory is correct and the TT is about the same weight as a .46 FX. Get the 47" Yak! It's a jewel! Love the way it pinwheels and tumbles. Hovers are sick stable and so is the upright and inverted harriers. Flat spins either way is easy to lock into. All in all just a very forgiving and silly fun plane to fly! Oh and yes I have dorked mine. Lost power in a low torque roll and she nosed in from about 9feet up. New prop and carb clean she was in the air again.
