RE: Telemaster engine??
Scott they are OS 25FX's And the only bold statement is I love Multis and I love the time honored modelers art of 'Kit Bashing'.
What made me think of it was This one and a bunch others. Donor here of my original Quad Kaydet is a Senior Kaydet of course:
Back to your ship which I beleve you will love, I,ve also flown them with two stroke Sixtys But I think your small four stroke will be a bit disappointing as you surmised. I,ve also set up some airplanes that I did deliberately use smaller that the recommended engines So give it a try if ya like to experiment. Its all good.
