Try a profile like the (Omp) Edge 540 or the Morris hobbies Sledge 540 if you wait until Jan the Yak 46 will be ready to buy as a kit. And you will not have to make any mods it will do all the 3-D tricks and will make you a OMP LOVER. If you wait they will be ARF the planes soon It will be great when they Do. There is a need for them. Go Mike (OMP), O If you make them better let me know.
