I am going to be buying a Tekno MT410. I have been looking at all the upgrades to buy before the build. I am wondering if the stock gearboxes break ever? I see ALL Racing makes the aluminum ones and wondering if they are the way to go? Tired of breaking the gearboxes on my 1/8scale ebuggy and need a real Basher that can handle big air and crashes that go with it when not landing perfect. If anybody can put together a parts list with all the great upgrades would be very helpful. Thank you.
