Very, very nice work!
Ingenious CRC 1:12 stylee battery straps!
Only thing you should beware of is that the batteries can be thrown around quite a bit if there's a hard impact. On the 1:12 the rear damper got bent by the batteries giving it a knock... LiPos are much lighter than NiMH, so not a big problem anymore though...
That weight adding system is just perfect!!!
