1st float plane suggestions ...
>>I have a set of Great Planes 60 size floats and was expecting they would be about right for the Telemaster.<<
Yep, probably just about ideal.
>>What set of floats are you using on the Senior Telemaster?<<
I make my own. White foam, v-bottom, tapered sides. Sheeted with balsa except for plywood near the step where it sits in storage/transport. Covered with aluminum Coverite. They look something like scale EDOs, but I don't taper the nose in the "Plan" view.
What engine are you using on the Senior Telemaster?
OS.91 Four-stroke. Rotated 90 to the right. Onboard GLow.
Oh, yeah. I bashed mine to make it look like a Beaver. Round cowl (courtesy of a Tupperware Iced Tea Pitcher), Dehavilland-shaped vertical stab, Funny-shaped window stickers. It'll fool you if you stand back and squint.
