Ok o here are the pics maybe an oval guy can explain it to me but if I add the left front and back it's very close to the right front and back. 56g difference. So if I chose a different motor and esc as per tekno I would be completely balanced.

-----------------Serpent--------------------------------tekno
RIGHT SIDE: *1858g ---------------------------------1679.5g
LEFT SIDE: * 1914g ----------------------------------1659.2g
DIFFERENCE: *56g------------------------------------- 20.3g

FRONT: * 1852g----------------------------------------1609.3g
REAR: * 1920g-----------------------------------------1729.4g
DIFFERENCE: * 68g------------------------------------ 120.1g

So the serpent is more balanced front to rear as the difference is 1/2 of the tekno and 36g greater difference left to right. I don't see any validity to their statement on neobuggy. I'm sure I could also swap out motors, esc's and batterys as they did to get the values even closer. (my values above are also with the body on, if you looks at the pic with the body off the totals are much closer to the tekno car)

Here are the pics






And a pic of the killer CF batt straps. Nice product
There was another serpent at the track yesterday that was running them too and he was very pleased as well. Chris managed to beat me again by 2sec
