Sure glad to see you get back to this plane!
 Mine is 95% done... being new to the 35% game and it's new technologies is stressing me out.
I went with the Booma Smart Buss Extreme and for me, It didn't make things easier.
For some reason I believed it was going to have the auto servo matching. Phhht   NOT!
Then I got to the supplied opti kill...  I again learn that it has to have a separate battery!
Why in the hell would you design a power dist. without considering the ign. power???
   Other assy. Threads were saying they were coming out tail heavy. So in my infinite wisdom
I installed a plate over the tunnel and placed the tank and batts there. And put the SB in the original
 tank location. I haven't checked the CG yet ...  but I have butterflies in my gut that I may have to completely 
redo the innards of this thing. 
 I'm really looking forward to see how you set yours up. I need some better ideas to follow then the ones
my feeble mind keep handing me.
