so you mount your rudder servo further forward, not toward the tail right? I looked at it, but there's not much wood (if any) at all further forward (but that's why I guess you reinforce it and make your own mount I guess right . I assume that this is a pushrod config, not a pulll-pull right?

Also with the rudder servo this far back, how far do you need to mount your battery to obtain the CG you wanted? And what size battery do you use?

Thanks
