I originally hijacked another thread with this , and would like to correct that now.
My Leopard had a bad turret rotation motor and a sound problem
Thanks to the help of YHR, also known as Dan ---- an excellent customer support representative named Murphy has resolved my situation with the Leopard 2A6 that I got during the Mato Labor Day sale.
A new turret rotation motor is on the way. Also, how to adjust the sound (and smoke) with the transmitter was explained to me, and shown to me with a Video !!!
The buttons to control the volume and smoke are in the place where the frequency crystal used to be. They are small side by side buttons and I didn't notice that. I need to wear my glasses more. The instruction manual identifies that place on the transmitter as the "crystal socket" on page 6. I guess I have an old manual.
So everything works great and now I am happy with my Leopard, Murphy and Mato.
I should have given more time for a resolution to this situation to be worked out before I shot my mouth off on a hobby forum, so my apologies to everybody are in order.
Thanks Dan
Rex
