A word of caution here: My Senior Telemaster ARF is powered with a Thunder Tiger Pro 1.20 two-stroker (sounds like overkill don't it? it's a glider tug, so I need all that surplus thrust). Anyway, while towing last weekend at the Alpine Soaring Adventure (Wallowa Lake OR), my engine pulled clean off the firewall. The engine mount beams ripped free of the inside fuselage sides. They had used hot glue (yup!) to adhere the beams, and the glue joints failed.

My fix will be to strip the fuselage and plank the sides with 1/32" ply, plus I will mount the engine with a glass-filled production engine mount bolted to a new 1/4" firewall. I already beefed up the aft section of the fuselage with 1/64th ply veneer, as the tail had way to much twist and flex in it. Lesson learned: the Senior Telemaster ARF is a cheap-o Chinese product, with way-too-soft wood and poor quality glue joints (hot glue cripes!). Don't assume anything with regard to structural integrity, and if you decide to overpower it, plan on adding some more stiffness with ply sheeting like on mine.

Enjoy, the Sr Telly is a wonderful flyer.
