John, one of the biggest sellers was the power needed to fly, yes the JL version is bigger, the Large version of Skymasters can fly useing a 20 to 36 lb turbine. I also watched the video of the SM L-39 powered by a jetcat P-80 and it flew great and on landing it comes in at a very low speed.

I should have mine in less then 2 weeks and then I will start a step by step build thread.

time to get out to the garage and clear off the work tables..
