I've got a G45 on mine, and it comes out pretty nose heavy with that. Another guy here is putting one together with a G62, but hasn't flown it yet. I think you'll probably have to add a good bit on tail weight, but should still fly OK. Mine topped out at 23. If you like the other Telemasters, you'll love this one. I had a build thread on it some time back.

The G62 I would use has been modified by Ralph Cunningham. It is one of his G62 Lite engines with EI, which should be considerably lighter than your G45 (used to own one of those too, nice engine).
