Just thought I would pop a post on here about the Viper volume control board.
I now have 5 of these fitted in tanks and find them a great addition. Being able to turn the volume up and down from the Tx is definitely a bonus, and much easier than other options I have come across.
I have these hooked up to a mixture of Clark and IBU2 boards and 9X and 9XR Tx's, and they work perfectly. Well worth look.
