I did not see - what size & length lines are you using?
Warps & tip weight sound like likely causes. The warps part incudes double confirming that the flaps were glued on straight, if not they make really big (out of ) trim tabs!
Like Tim said the necessary tip weight will be greater with an electric because there is no engine & tank hanging off the side of the fuse. Can you weigh the outboard wing tip? Put the bird upside down, resting on the top of the fin, use a box or something similar to hold the nose up so the (inverted) fuselage is approximately level. Presumably the outboard tip will drop - however put a scale under the outboard tip (prop it up so it is roughly at the level of the wing) I'd suggest overkill for starters, add weight until the tip weighs 1 oz. If that is too much you can remove it after you get a few flights on it.
About the CG: you said you have it at the same spot as the IC version, but the IC airplane gets more nose heavy with a full tank of fuel, so the electric should be balanced further forward than the IC. Move the CG forward at least 1/4" to 1/2" CG would not by itself make it turn in, but CG & leadout position work together.
After the first crash, did you check to see if the elevator was damaged? Trying to remember, doesn't the Akro have the two halves of the elevator joined by a wood stub? If so, if you applied UP elevator and if only the inboard side moved it could cause a roll-in.
Next up would be to try a pusher prop, to get the torque working for you.
Don't give up - success is in sight!
