I've built several of the Sig Pigs and love them. I have put anything from .61-1.08 2-strokes and several types of .91 4-strokes in them and never had a problem with any of these engines. I have run small props with deep pitches and large props with shallow pitches. None of these have created torque problems on takeoff.

You can slowly advance the throttle and control it on the ground or you can jam on full power and be off the ground in about ten feet. Either way, if you take time to set up your tailwheel steering you won't have a problem.

I prefer the .91 4-strokes over the 2-strokes. I normally run a 14x6 prop with no problems. I can't imagine why the other guy was having any problems on takeoff. Good luck with yours, you'll love it.
