RE: 2 stroke suggestions for Senior Telemaster kit
I don't know if this helps, but my .40 size Telemaster had a Magnum .46 bushing (2s) motor, weighed ~7 1/2 lb with floats and took off in ~250 ft on water. I don't know how much static thrust a OS .60 FX produces, but the OS .91 (4s) will give you ~7 1/2 lb static thrust with a APC 14x6 prop. Perhaps someone else can give you some 2 stroke data. One thing I would look for is a 2 stroke that can easily spin a 12 to 14 inch prop and give you static thrust equal to ~70% of the RTF weight. Note, my electric Sr Tele weighs 10 1/2 lb RTF. My guess is the Tower .75 should be in the ballpark for you. BTW, I'm starting to break in a OS .55 AX (2s) and it swings a 12x7 APC prop. Good luck!
