i tested with stock gears, soft tires (pink) in the rear, and hard tires (blue) up front, single cell 200mah
king 4.2 pro works pretty well with booster cars........i still dont like the unboosted mode as compared to the boosted mode.....the car seems like it needs 2 sets of tires, one for unboosted, and one for boosted.........or something to prevent rollover........unboosted needs more like 3/4 power and then the full power boost..........my $0.02
but the king 4.2 is pretty damn fast.........the 2 im playing with flip the cars like nothing ive seen........looks like more tuning.......i tried my hand with suspension springs before and didnt like it, but i think now i need them springs.
the king motors leave the perfections 3.8 behind off the line and finish by a good 2 to 3 feet on a 16foot straightaway, good torque but i think i need stickier tires.
my last bit test was with full pullback wheels, this seemed the best for track racing.
on a zip-zap, the king 4.2 eats the 3.4 NX motor up, theres just no comparison. great speed and good control (soft pinks at the back, stock tires up front, single cell 200mah)
the king 4.2 motors eat up the batteries.......
bit booster, 200mah i got about 30 mins of runtime on a track
bit single speed, 200mah i got about 20 mins of runtime on a track
zip, 200mah i got just under 19 mins.
i dont have a phast motor
