I have one of these from Raidentech. and as stated earlier the directions leave a lot to be desired. However, the quality is very very good.. I am planning on a 90 degree mounted O.S. 46 LA with a slimline Pitts and a 11X6 prop. Since I am planning on taking off of grass from time to time I have removed the wheel pants and added a little bigger wheel. Hope to have a pic soon it is white and purple. Can't wait!!!!! [8D]
