My son has just moved house and donated his RC tank to me after 15 years of it sitting in his loft. It works fine but the gun does not fire. Having taken it apart I find the 24/8 nylon gear has a tooth missing. I have now spent days searching for a replacement and just about given up. I am starting to think that its just too old, bit like me! But as a last try I thought I would ask the experts. So am I wasting my time? or can I buy the gear or mechanism anywhere if so please point me in the right direction or put me out of my misery adn stop me wasting even more time.

thanks
Colin
