Thanks for the kudos guys!

Fred: Thanks for the link! It looks like a good solution. Have you linked two of them together? If so, how? Also, does the unit run of off the Rx battery pack? Thanks!

n6iap: Hmmm....I thought of trying that but didn't want to let the magic smoke out of the unit. Stepping up the battery to a 5-cell will be my next step. If that doesn't work, I might go with the above suggestion. BTW - why did Keleo put the exhaust at 9 o'clock instead of at the bottom? Thanks for the battery info!
