ROFL... OS 160 2 stroke on a 60 size plane. Might have a slight ballancing problem ... along with the 4 pounds of fiberglass to keep the firewall attatched to the plane. [:P]
I have an ASP 1.08 in an Ultimate ... and I've got an OS 1.08 FSR in a U Can Do. Both spin an APC 16X4W and both have unlimited vertical. The Ultimate weighs about 13 pounds and will go vertical as soon as the tail clears the ground. The UCD weighs in at just under 8 1/2 pounds, and I can't keep it still.
