Nickrummy,
Sorry to hear what happened with your radio. Hope you can find a way to get a bit of money back out of it. If you are looking for a radio to operate a tank with I would suggest that you check out the RC Tanks forum here on RCU. You can find that forum here: [link]http://www.rcuniverse.com/forum/forumid_369/tt.htm[/link] . I know that a lot of the tankers use different type of radios to control the various functions on their vehicles, and they would probably be able to answer your questions better than here.

Hope this helps

Ken
