Waldo, on my last job we used to fly these for da military. I have the Goldberg version. We didn't have a manual or book and I have never seen one for it. Pretty much flew it w/ K.B. .61/.65; HB .61/.61 PDP engine. We used standard 5 min. epoxy for assy as we had to build purty quik if da gunners got lucky. I don't recommend anythang bigger than a .90 unless you do some serious strenghtenin'. on da wings; as it only has a piece of packin' tape runnin' spanwise. Also the nose area needs some reuppin'. These planes weren't designed to last that long and therefore quite expendable.You gonna have to be a little creative w/ da servos, L/G etc. I plan on mountin' mine using a standard nosegear from G/P or Sullivan. Also using standard alum. main gear. Naturully using plywood inlays for a mountin' surface. Also some of these guys lately have been using Gorilla Glue for foamies and fiberglass. Li'l goes a long way tho'.Anyway IMO youra gonna have to be creative, but try and keep da weight down if you want a good flyin' model. Also there was an article in MAN about using LOW-temp covering for your color selections.I plan on goin' this route when I get around to it. Sorry to many other projects ahead of it.Anyway just mods are in order as these planes weren't built that strong or to last long. Thanx,Rob
