Good morning!
Well, this is a disappointing read. lol! However, I am not surprised. The airframe as you see it weighs in at just under 3 lbs. So a finished, rtf model would be at least twice the weight. I have been down this road with an old Kyosho P-40 arf designed for a 52 4 stroke. Decided to put a heavy Saito 65 in it. It flew nice but it had a pretty high wing load.
At least I don’t have anything into this yet. I think the nacelles are way over built.
Thanks for your input.
