Sonny Weller does most of the RV stuff here at DVT and is very well respected by all of us. If you have the RV, He does not have an RV available. His # is 602-463-4863 Good luck, Larry
I recently flew with Sonny in his Pitts. We did spin training, upright, flat, inverted and cross over. He is and excellent instructor with a very comfortable teaching style.
