I'm assuming your lipos are too tall to fit under rear bulkhead/shock tower in rear motor config?
If so, take the rear apart and shave down the underside of shock tower bulkhead area where lipos sit under by a few mm using a dremel or flat file, you should be able to fit any lipos then... i use LRP saddles and they have very chunky cases... fit in both my mid and rear motored 22's easily.
You only need a new body with higher sides in mid config if you decide to turn saddles 90 degrees side by side in front of motor, then you will have to trim side pods and use a clever mod i use to use velcro straps or you'll have to fit a lipo brace...
standard mid motor you have to use either saddles or stubby lipo and with saddles its best to remove battery front brace to fit electrics in comfortably... (i run speedo up front behind servo.... Savox low profile servo too)
its very straightforward, can't understand what all he fuss was about when the first came out, bit of common sense with install and anything will fit.
