I was hoping to get input from someone who had done it already. I've been out of the hobby for a few years and just ordered a Senior Telemaster kit. I plan to power with a .90 to 1.20 4 stroke OS or Saito. I'll probably build it as the plans suggest to get my wings back, then build a set of clipped wings later. I figure you could just do the math to get the wing loading up to about 25 oz. It should still be mild mannered with that loading. I would suspect.
