On my Sukhoi it looks like I have to shift batteries to the front to reach the correct CG location. Of course, my DL 50 is a lightweight, too. I don't think there is a problem ending up nose heavy withthis plane., unless you put a Zen-62 in it

Then space the engine out as much as an inch ahead of the cowl to help it balance, won't hurt anything and may make the prop a bit more effective.
