If anything the price should be cheaper than the 007 here is why:
- EU car has no alu multidiff but the delrin spool plus a rear plastic diff
- US has no alu diffs but two plastic ones with plastic outdrives
- they did not add the alu shocks they just announced so the same old plastic comes in the kit
Last time I checked plastic parts are cheaper than alu parts... I'm not questioning if those are better or not for the application but they are easier and cheaper to manufacture for sure.
I'm just guessing here but I think one reason why xray went with the plastic is the ridiculously low minimum weight EFRA came up with for the 5 cell (1350 grams). They are trying to shave off every gram they can...
The US version may not fit the 4800 Orion (23mm thick) but the 5000 maxamps (18mm thick) should not be a problem...
. I think it is Kokam's turn to come up with a thinner LiPo cell design in the 4800 capacity range.
