Hi all,
I am in the process of planning a stick change in my RV-8 (pilot's seat) from a Ray Allen G205 grip to an Infinity Grip (hereafter referred to as IG)
Right now the stick functions are:
PTT
Flaps up and down (2 buttons)
Auto-pilot disengage.
The elevator trim is a ON-OFF-ON rocker switch on the instrument panel. I'd like to move that to the coolie hat of the Infinity.
I have a few questions regarding this project and I've worked out a basic plan about which I would appreciate comments/criticism/suggestions.
Instead of writing about everything in one massive post I'd like to present a question or issue one at a time.
Issue #1: Relays
=================
The Ray Allen web page says this:
"The modern design G101B, G205 and G207 stick grips use four, flush fitting pushbutton switches to control one or two axis electric trim. These SPDT, momentary contact switches are rated at 5 amps. They can be wired directly to Ray Allen trim servos, eliminating the need to wire relays in your trim system when one grip is used."
The IG web page sells a relay deck so my assumption is that for the flaps and elevator trim servo I need a couple of relays (each) on the relay deck.
Question #1:
============
Do I need a relay for the PTT? What is the current like on a PTT
switch?
Or can that be just a direct connection to the PTT switch on the IG?
Thanks!
