I have the grey tiger with smoke and sound, but the remote and tank stopped receiving signal from each other. The tank turns on, but the lights just blink. I took the remote and tank apart and did not see any loose wires or anything. From reading other post I'm guessing the main board needs to be replaced. Is there anywhere to buy that besides matotoys? The shipping cost more than the parts.
Thanks for any help

Swap out the crystals with your spare set. Check the antenna and connections too. I always advise that everyone buy a smoke and sound upgrade kit in lieu of the board the first time around. You'll get an extra transmitter, crystals, speaker, smoker, screws, etc. Great value. Buy that, some metal tracks and a PZIII and the shipping won't look so bad when you're done shopping!

Hello K_2yle
I have just had the same thing happen to me twice in the last month on two new tanks I ordered.The lights on the tank would flash,but that was it.The problem in both cases was the crystal in the tank that plugs into the main board.After checking each crystal on a working tank,each one in the transmitters was OK,but the other half of each set that went into the boards was bad.Also check that the one for the transmitter ( has TX on it,and the one off the board has RX on it.)You can also check that they are the same frequancy.(Now this was on new tanks) in your case if you had been running them and this happened it could be a problem some where else.But if you have another tank that you can swap crystals i would try that first before anything else.Also push on the crystals in the radio and in the tank to make sure they are not just loose,this happened to someone else here on the forum and it was just a loose crystal.Good luck and hope its just something simple.

P.S. you can buy crystals from tower hobby that will work in these radio's,(RC RED HAWK BRAND)They are around $5.00 dollars a set and shipping is like $3.99--You can order several sets and the shipping is still the same price.(hope your in the U.S. --Didn't look to see where your from,price and shipping applies here in the states)

Since the tank won't start, I agree I think this is a TX/ RX problem. Make sure you have fresh batteries in the transmitter, and the antenna is hooked up. I doubt very much this is a board problem. Lets us know how you make out with this problem.

ok thanks guys I'll try getting the spare set first from tower thxs bigmig
