Thanks, guys.

What do you think ? Doug and Frank, Using relays to control main power negates the concept of a true external master kill switch. Rough battlefield conditions could cause relay contacts to weld closed. I require all of our student-built vehicles to have an external master power switch. Personally, I recommend the 75A push-pull switch from Robot Marketplace. It is relatively compact and has never failed for us. The only downside is that you might get accidental shutdown by backing into an object. Conversely if you get a runaway vehicle during testing, you simply swat it in the ass with a broom. http://www.robotmarketplace.com/products/0-SW75.html That said, I have no problem for tanks in our hobby to use relay kill switches. However I recommend to include a true master power switch somewhere albeit internal. Joe -- -- You are currently subscribed to the "R/C Tank Combat" group.
