balance came out right on the money, seems to be just about right. I put both my lipo batteries on the right side about mid way of the fuse compartment andone regulator and receiver on the opposite side same area.

I also considered shortening the standoffs a bit to make the engine fit more inside the cowl, but elected not to in the end. One at our field does not use a spinner and mine does, both look OK with the engine mounted on the stand offs as sent from PEAK. Try it first, if you don't like it, you can modify it later. PACO
