It's not the backup I am concerned about.....it is RF interference coming down the long lines in the UltraBandit.....even if a lead to the smoke pump or NG happens to be shorter, it runs close to longer lines, and may pick up some stray RF......there has been much discussion about the servo motors themselves generating a back EMF of suffiencient strength to cause glitches in the RX.......so it is best to protect all the lines coming into the RX.....

It seems that these Powerboxes, from all the manufacturers, were designed for Giant Scale Sport Prop planes, who were the guys to use them first when the Duralite PowerBox came out a few years ago.....and they don't usually need as many channels as Jet Flyers do.....I see no other reason why they would design a box with only 7-8 channels......

If Smart-Fly can do a 10 channel box, why not Duralite and Emcotec? Maybe size constraints as my 8 channel Emcotec is a pretty large unit as it is....
