Light, plenty of power, more than enough current and reliable as is necessary...nothing complicated here.

Duralite 6.0V Failsafe Switched Regulators - ignition, receiver, receiver
Never had a problem with these switched regulators. Duralite service is excellent. The two RX regs are matched at exactly 6.05V (read when attached to RX). Six volts is on the upper end of the range for DA, but runs the engine just fine and doesn't dissipate too much energy to heat.

TBM 2350mah Lithium Ion Batteries (3)
To slice right through the debate, it works. Great flying times...10 fifteen minute flights - easy on this battery setup, perfect for a long weekend of flying! Anything more and I would add weight. Each battery is only TWO cells...nice.

JR 945S PCM Dual Conversion RX
I decided if I was going to run only one receiver I would run the best that money could buy. Maybe that will be Spektrum next year, but right now it is dual conversion PCM.

DS 8611 servos for all flying surfaces
Why not supply the flying surfaces with as much torque as possible in a standard sized servo case? Ok, the case is a hare larger, but hey, it was worth the little bit of trimming I had to do. So far the metal gear JR digital servos have performed flawlessly over more than one hundred flights.

Hitec 5245 MG on throttle
Metal gears keep vibration issues from being a problem by stripping the gears on my throttle servo, digital gives me the same idle as well as the same throttle position throughout the range of my input and the mini size gives me plenty of options during mounting.

Hitec 225 MG on choke
The same size as the throttle servo but digital isn't needed on this little guy, but I stuck with the metal gears to combat that vibration. With well over 55 oz/in at 6V this little servo should be able to handle the choke actuation without a problem in the event that my throttle gets stuck and I need to shut down the motor in an emergency.

What better than some nice black self wrapping hook and loop fasteners to hold everything down over silicone rubber padding. I chose the 1/2" thick foam so I could smash it down a bit while tightening the fasteners and still have a 1/4" or so to isolate the electronics from any vibes that might make it back to the radio compartment.

As for the layout, we'll see if I have to move those batteries back, but for now they are in a fairly neutral place. The regulators were the furthest away from the switch mounting holes that Tom so graciously had drilled for us right behind the trailing edge of the wing. Everything should mount up with few flailing wires. Any loose wires I will secure with JTec fasteners or hot glue!

My receiver antenna is going to go straight down and out the fuselage, run along the bottom of the fuse and be held mildly taut with a properly sized rubber band or two. Notice: I taped in my RX crystal...HIGHLY RECOMMENDED!
