GPS cripple-no way. My first year with the W10? AZ to WI no nav equipment, chart and compass. last summer NY to AZ my GPS and IPAD were both inop most of the way.? I am still trying to understand why the RV accelerates so well with only 160 hp. I think it would be very close to the Pitts S1T with 200 hp and at least 200# less weight on takeoff. The climb would not be as good as the Pitts but still impressive.
