Ok.....ive built 3 of these. The first onbe weighed 16.5 pounds with a turnigy 6364-230kv motor on 10s. It had an 18x12 prop and the sierra giant gear designed for the wing.
Plane flew well, landed rather easy with half flaps, but it did want to torque left...juts likem most tail draggers. My CG was 108mm. I did not add wedges to the gear, but did use a couple washers to rake the gear just a tad. Nose overs wherent that common, but I did try and use the stock spinner and that was the downfall of that plane. It shattered in the air(after a quick prop strike on a rare nose over take off). Plane took off, but about 10 feet up is when the spinner came apart.

2nd one I used a Dave platt aluminum backplate, fiberglass/resin spinner. Much better. plane weighed a little less at 16.3 pounds. Flew just as nice, but used an e-flite power 160 on 10s spinning a 15.75x13 3 blade. This one eventually went in becauseone of the serialed battery flight packs went south just after take off. Plane stalled and that was that.

The 3rd one still has the e-flite power 160. Weight is 16.3 pounds again, but prop is now an 18x12 Turnigy beech wood prop. Take offs are much easier as these props develop a ton of thrust.

Do make sure u gain decent speed on the ground. Don t yank her off. Keep the speed up some on landing of course till u see how it reacts at slower speed tests(up high).
