hey guys this is a question for the ones that have built showtime 50`s, i put a saito 91 in mine and it`s a little nose heavy, i put about 2 and a half ounces on the elevator hinge and it balanced great, i really just want to move the battery, but i really can`t see a good place to put it, i`m sure someone`s had to do it, i know it would be hard, but could you post some pictures??
thanks for all your help.

I have the same setup, but only needed 1 oz of weight in the tail to balance.

I did not move my battery back, but you can install a battery tray just behind the hatch. You can cut a piece of plywood to just sit on top of the ridge on each fuselage side.

BTW, I found the stock engine mount too flexible for the Satio 91 and went with a Dave Brown 90FS engine mount instead.

hey frank, thanks for the help, i rebalanced the plane, and it balanced great, it must have been something i was doing, i don`t know.. the dave brown fs90 mount? will it mount in the same holes as the plastic mount??

No, you have to drill new mounting holes for the Dave Brown 90FS engine mount.
