LSP 972- The most recent GP Skybolt ARF is pretty much the same as the earlier ones, with their selection of wood that thay use. I bought mine used/ wrecked at a swap meet, and only the firewall, and front formers were damaged. The previous owner that I bought it from has an OS 91 4 Stroke in it, and on his 2nd flight, he ground looped it, and the OS 91 went straight back and took out the firewall and F1-F4.
I did a refurbish of it, and have an article in the "Crash/Rebuild" forums here on RCU. If u go to that forum- go to page 4, and look at my article "GP Skybolt crash find" near the bottom of P4, and u will see how I rebuilt the front end, and added a lot more structural integrity to the front airframe. When u go to fly urs, make sure u let ur groundspeed get hi enough, and it will lift off effortlessly. You also may want to cut, and add an additional 1/8" ply firewall to the existing one for added support. I'm flying mine with an OS 61SF long stroke, and it will do anything I want it to. Here are a couple pics, but u can check out my article if u like. Let us know how u will progress with ur assembly, and maiden flight- Best of Luck-- Dean
