I'm not sure, 2nd gear on it still has a fair bit of go in it. But then it's all geared down so hard to say.
Low end and reverse is ultra smooth though, it's definitely worth the upgrade. If I built another I'd go for the 2200kv though, bit more money but even slower and smoother on the throttle.
This is everything I can remember.
Traxxas Trx4 Kit Version (Comes with 2 speed gearbox and remote locking differentials and you get the fun of building it from scratch)
Carisma SCA-1E XL Pajero Body Shell (very cut down to clear the wheels and approach angles)
Fastrax Aluminium Motor Mount
Traxxas 9t Pinion gear (to drop the speed down)
Traxxas Diff Spools (to permanently lock both diffs)
Hobbywing Quinrun Fusion 1800kv Motor (Turns so bloody slowly it's ridiculous, also has the esc built in, waterproof with a 7.4v BEC output.)
Custom led light bars (super bright, run off the receiver and modified to work with the remote switch that used to lock the diffs)
SRT W45 Waterproof steering servo (standard traxxas servo is about 9kg of torque, this is 45kg and can run at 8.4v)
Jumper cable to run servo direct from the battery.
Yeah Racing Low Centre Gravity Battery Plate.
Injora Deep Dish steel bead lock rims (these also have 60g of weights glued in the front wheels)
Injora Underdrive gears 10/35t (dropping the speed down even more, I may overdrive the front to help with climbing soon)
Injora Dual Stage Foams
And then Brassssss lots of brass.
Injora Front bumper with servo mount (moves weight forward and down lower)
Injora suspension chassis links.
Injora Outer and Inner portal housings.
Injora C knuckles.
Injora 12mm Hex extenders (wider track)
With all the brass, roughly it's added around 1kg over the front axle which really helps it climb steep ground without looping out.
