i have a lightning vx its pretty quick i killed the 44 th throttle gear though and im waiting on the new 1 the tires wear thin fast on them and make sure theyre glued on good 1 my right rear wasnt and it flew off the rim. i bought a couple extra gears and some m4 grub screws because they fell out of the rear universal joint so check all your screws also the crystals for the servo were two different so if the cars not responsive thats why
