I think most points have been covered in this interesting thread , but I emphatically disagree with Mark on one point, about twin battery setups, they do reduce the risk of total power failure almost to nil. KISS is great, if the simple approach will get the job done !

Tom, we are indeed reading from the same page but to muddy the waters a little I have just received a description of a new Australian product the, "I Switch," from RBA in Perth. This is a device to provide separate servo power, opto isolation and signal amplification in heavy duty applications, and makes the point that it is the plugs and sockets which are the weak link in current use (sorry about the pun) being rated at only 1 amp before voltage drop starts to occur. (I think Speedbird made exactly that point) so anyone who is using lots of high powered digital servos through just one JR deluxe harness, which use standard connectors, may be grossly overloading the switch harness.

On the Duralite cells connecting to my Powerboxes the cable is 16 AWG and the connectors are the heavy duty multiplex type, which match the Powerbox.

In reply to an earlier request , I believe MAS is no longer making the volt logger (or anything else) but try Intairco (www. intairco.net) they may have them, and they are excellent devices.

Tom, glad to hear you are back flying, driving to Oshkosh from Chicago last July, the countyside looked beautiful, green and lush, but I imagine its pretty bleak in winter. Last Sunday here was plus 25 degrees, (C!) light winds with scattered Cu at 3,000 ft., perfect, and a lot of Jet A as burned. Good luck with the Ultra Bandit, it looks superb.

Regards, David Gladwin.
