I received my Hellcat in the mail and it is Awesome!! BUT retracts, I am not too sure that the Robart 615's I have are going to fit without a bit of re-engineering. I have made preliminary measurements and now am making templates before I cut the covering. The covering is fabric and paint. The paint seems a little soft as I managed to scratch the Blue pretty easily. The construction and glass work are better than the GSP P-51D. I finished one of those last month. It is powered by a YS 1.20 and the Hellcat will get his brother. I have the FW 190 and Corsair sitting in my basement waiting in boxes. They too will get YS 1.20 engines except the Corsair. It will get a YS 1.20AC.
The Hellcat is going to be definitely lighter due the build up wing versus the sheeted foam wing of the Mustang.
I have seen other construction articles here with pictures. I will charge up my digital camera and post pictures here.
The Hellcat is a well built ARF and I am anxious to get it together.
It has the same 10 page instruction sheet that most ARFs have with not a lot of detail. Just pictures and Arrows. This plane deserves retracts and I will figure out how to get them in and operating.
