I've been searching the internet for information on how to set up a gas plane. From what I've been able to gather, I drew up some diagrams.

I finally got the c.g. right on my 51 inch AJ Slick. I just kept moving it back, which required multiple tries. I think I flew it and landed it at least six times, bringing the battery back until it flew level inverted as well as upright. I was going to mark the c.g. at the wingtips, but after a hard maneuver, the canopy came off. I spent a couple of hours looking for it, but could not find it.
