RE: .30 Saito gold anniversary edition
Vintage?
The Tiger Shark is that, for sure!!
If you can scratch build, I suggest the Tiger Shark.
You could size the model to fit the engine.
Mine has an Enya 120 4S in it but I sized it to 72" in span.
Not many know this model, but, in some ways, the Tiger Shark started it all. That's the fuselage of my Tiger Shark on the bench.
Here's some photos.
