Phoenix Models makes a quality Tiger copy in a few sizes, and I decided to make the 71 inch 15cc version into a twin. Running two OS 46AX engines, it is a fast plane to fly! Those ARFs out there make good platforms for all kinds of conversions. The plane actually flew on a single OS 46AX on the nose but it had anemic performance for aerobatics as one would expect, and it was floater on landing.
