I tried posting this question in the radio area with no results yet. I am hoping there is more response here. So I am looking at the Powerbox Cockpit 4610, Down and Locked Secure Flight, or Smart-Fly EQ6-Plus. Who is using what, in what, and what are your flight pack requirement? I am looking for a system to retrofit into a few WWI & WWII 1/4 & 1/3 scale birds. I currently fly the Futaba 12FG, and looking to maybe upgrade to the 14SG. No gyros yet, but my next build will have one on the nose wheel.

Thank you.

keep it simple and use a powerbox Gemini a 6014 receiver and a orbit powerjack this is the system I use in my 1/6 f16 works fine, the powerjack boosts signal the servos and with the 14 channel receiver you have spare channels for extra servos

I have the exact same set up in 2 planes, except in one I have a Powerbox sensor switch rather than the Gemini. The Orbit powerjack goes an increased signal without the need for a Powerbox.
In my next plane I will have a Powerbox srs so I can use the latest cheaper receivers. The 6014 is a great receiver but it is very expensive. I use A123 batteries in all my planes 2 cell for receiver and 3 cell for ECU.

I too have a 12FG which I have had since they came out and see no reason to change for the moment.
