RE: Name the plane?
The model in the picture has swept leading and trailing edges (to the rear). Sig's Kobra, nor did the Kougar, feature a swept wing. Yes, it could have been bashed from one of those Sig kits.
If it is a stock kit of some model, it wasn't very popular because I do not recognize it and I would recognize it if it had been popular.
It's not a bad looking model. I'd like to fly it a few times.
