Well, I got my gearboxes today. The good news......the gears are 1000% better than the metal ones. Bad news... I got the low profile gearbox and it wont mount correctly in my Tiger!!! The gears are arranged differntly in the low profile gearbox and they cover the forward mounting hole in the left gearbox. I called Bill at RcCommand and he suggested that I use the old gearbox and put the new gears in it. It took a little work, you have to press off the small gear on the drive shaft and flip it around and press it back on,but I did it and its all back together and works AWESOME. I asked Bill if there was a diffenence between the motors with white caps and the steel ones and he said go with the steel ones, there diffently better. Now, I have to wait for my working machine gun to come before I can get the Tiger back together. I've had this tank since the first week of 09 and I've gotten to run it about 15min. I've been spending the time painting and detailing. Oh, and in case you dont know, the new steel gearboxes come with plugs on the wires, the old motors where soldered on the back(top) of the board. I realized there are plugs on the other side(under) the board. You just need to plug the new motors in. Then remove the old motor wires from the top of the board. Im glad I saw the sockets under the board, I almost cut the leads!!!
