I did the Sig kit 1/6th clipwing a couple of years ago. The motor I used is probably irrelevent now, being an inrunner that's not around in the US, but your 46 would likely be too powerful and too heavy - I'd reckon their 32 would be fine, with a reserve of power, and their 25 fine if the model's not too heavy.
The image is the only one I could upload from my 1/6th Sig build. Being Sig, it's way better than most - their owner owned and flew the one they used as a prototype - and it had the scale hinged entry door and side window. The window got left off - 'legal' in a full sized Cub, for air conditioning - and the door could be popped open off its magnetic 'lock' to allow easy battery access.
The battery - 3S or 4S Lipo - sat on a balsa tray over the UC to achieve proper balance and could be easily removed for charging. I put the fuselage servos just aft of the cockpit, accessed from underneath.
Sold it a while back and don't have the exact figures, but on 3S it had around 350 - 400W into a 12 x 6 or thereabouts and flew very Cub-like at around 68 - 70oz.
If you can't alter yours to something that easy for battery access, taking the wing off to 'refuel' can soon grow old, especially if you have to deal with wing struts. If that's the case, go with A123s and build in access to a charging point.
Good luck
