Well, back from our mini weekend vacation in our new trailer, I did good buying this one, works out almost perfectly. One more TV for our bedroom and it will be perfect. The parts I ordered last week came in while we were gone, and aside from a bit of wiring, I should be ready to try to fire the 120R3 up again.
Doesn't take much room at all, and works with a light weight Life battery. Will help with balancing the plane since I can locate the battery where ever it is needed. The module itself is only .6 of an ounce.
