I just launched my GP RV-4 on its first three flights this weekend. I am absolutely impressed. It flew awesome. Either Great Planes designed it well or I surprised myself in my building skills on this one...but I suspect it was much of the first and a little of the latter. For those of you out there trying to hone your building skills and flying skills, the RV-4 kit is a great way to accomplish both at a great price. My model is finished in white and carries the stripes just like the box. I added some blue diamonds to the underside of the wing so that my tired eyes would have an easier time keeping track of it. Flew it without the cowl and wheel pants for the first three flights. Buy the way, I heaved the plastic cowl, wheel pants and wing tips and invested in the Fiberglass Specialties fiberglass parts. They fit great and I don't have to worry about them cracking if I look at them wrong. I installed the OS .50 SX with Brisson Pitts muffler and it provides plenty of power for this aircraft. Tried to get it to drop a wing in a stall but it flat would not do it. Flew very smooth on approach with the flaps down or up. I took some of the advice of the threads here on RC Universe and did long easy approaches because the RV-4 does like to float as she gets close to the ground. Anyway, I recommend this airplane kit for novices and experts alike. Fun to build, fun to fly, and looks good in the air or on the ground. Razorback11
