WOW! Thanks for the links guys, appreciate it
And the crappy battery that came with the gun is an 8.4 V mini, but I plan to go to the local RC shop and pick up a suitable charger and battery.
As far as the fore-grips go, do they fit just like the regular handguards, as in split into two parts?
"Replace your standard M4 handugards with these. Simply slide them into the delta ring, the same as normal. Caution: Batteries will not fit with these. A battery box or rear wiring to the stock is required." That quote off Velocity Arms seemed strangely worded to me.
Last question for now: If I was to buy a stock to house the battery, would i need to rewire it, or could i just get long enough wires to loop back around the gearbox?
