RE: SR Telemaster engine choice
Not to be nit picky but the ARF fuse is not sheeted at all. It is flimsy enough that after a season of flying (with a tower .75 for power and no crashes) the tail would vibrate at full throttle to the point I was afraid to fly it.
Be it the kit or arf, I would recommend sheeting the fuse. I had some 1/16 balse laying around and after stripping, sheeting, and recovering the cg didn't change much. The structure is much more solid for minimal weight gain.
