OK just for grins my approach is as follows: Fly the plane level parallel to my landing strip at approximately 6-8 meters high and reduce throttle to half. Turn the plane around 20-30M away from the landing strip aligning it with the runway and heading into the wind, reduce throttle to idle. Glide down to the landing strip making small throttle adjustments to prevent stalling. Pull up briefly before touchdown to reduce speed even further and to get a postie attitude (so the plane does not noseplant) Touchdown, and the plane flips over.

The plane has a battery hatch, which happens to be the only place the battery will fit, the weight that the plane comes with is insufficient to balance it out, or perhaps i dont know where to put it. I could rip off the glued cockpit and create some kind of closing hatch to put the battery farther back in there, but i would like to exhaust all alternatives before i start ripping things off my plane.

I will disassemble the rudder and elevator assembly today to see if i could fit that lead weight somewhere far aft, i am reluctant though, putting that part of the plane back together is a royal pain
