In my larger jets ( KingCat / Eurofighter ) I used the powerbox combination and it worked well. After talking with Jorge at Jets Over Whidbey in August I bought the A2 unit. It arrived last week and I have had a chance to play with it. I absolutely love it. Nice small, compact unit that is easy to program and install! Two receivers, servo synchronization, built in battery redundancy ( using 7.2 volt Nimh packs ) , safety switch, synthesized frequency that tunes very accurately to your transmitter.
