Thanks Tom. I know we discussed this before, but the more I thought about the rudder servos in the tail, I finally decided to put them in a pull/pull configuration instead. I'm using an SWB self-adjusting servo tray and I intend to mount it further back in the fuselage. I am using 3 A123 batteries (2300mah). The ignition batt I have already mounted on the tube. I have a C/F spinner and will be using a lighter weight wood prop...Looks like I'll need to instal the 2 Rx batteries directly in the tail.
