The above diagram is how the wiring was done when I got it (and still is that way).  I havent touched it...other than to take the battery out.  I found it odd as it only had 1 battery and all of the gassers I have seen have always had two, one for each ignition module and rx unit.  But there were no other places for a 2nd battery to plug in and looking at the wiring, the original builder/owner decided to do it this way and run 1 large battery pack.

Again, I didnt think it was the best practice...thus my post.  And am grateful for all of the replies in describing as to why its not the best practice.  I'll make sure to make the appropriate changes.

As far as servos...both of the elevator servos are side mounted at the tail and the elevator servo is inside behind the CG but not all the way back.

There is a battery compartment inside the firewall box that the original builder did not utillze.  I feel with running a 2 battery IGN/RX system and putting them both there...will allow me to remove most, if not all of the weight from the firewall.  I may or may not redo the engine mount.  Although it is very crude...it definitely is strong and I am not concerned it would fail.  IF I were to replace it, it would be because I needed to shed weight for balancing.




PS...I made a typo on the graphic...it should read 4cell 4.8v battery pack.  Sorry.
