I have the GSP/Jamara P-51 with a YS 1.20 in it and it is awesome. If you are looking for a good flying warbird with no bad habits. Then this is the one to get. I have the FW190, P-47, Corsair & Hellcat kits (unbuilt). I am having too much fun flying the Mustang. It did take a long time to get the kits from Germany, but they all arrived in excellent condition. If you have assembled a few ARFs, you should have no problems with these. I did paint my Mustang to dress it up a bit. I scaled it after the 4th Air Force, 336th Fighter Squadron (Red Nose) group.
I flew it yesterday and my buddy said, "I thought this is a Mustang not a Pattern Plane." It does a nice job of flying manuevers.
The FW190 & Hellcat are next to be finished.
Sorry no pictures at this time.
