My son dropped and broke my TQ3 tx that I use for my Tmaxx. A long time ago I put a rechargable battery in it, with a charging port on the back, so I really don't want to replace this remote. He broke the wheel off that is used for turning, so I took it apart and it's actually a very small black piece that I need, but can't seem to find anyone that sells parts for these.
Can anyone help? (I know it's old and a newer radio is the way to go, but $ is tight)
