ace models ALL STAR BIPE??
I had one way back when. It was a little heavy with standard s148 servos. It still took of in under 20 feet with a O.S. FP 15 in the nose. I would try to build it as light as possible and use HS-81mg's and go with a .15. With a .25 the prop clearance may be a problem. It was never a floater but with a little power on it would slow down for landings.
