Stick Grip Start Button

[rv4dude17]

I want to dedicate one of the buttons on my stick grip to energize the starter, but I don't want the button to activate the starter if accidentally pressed after start or during flight.

Any Ideas?

The RV-8? I’m buying has a Starter Enable button on the panel. Once the engine is running, that gets turned off. Viola... No electricity to energize the stater.

i have a starter button on the top of my infinity stick grip and i am very happy with it. Hitting it after start has never been a concern of mine.

Three easy possibilities:

1. "Arm" switch on panel;
2. Oil pressure switch (to deactivate starter power when running)
3. Time delay relay (gives power for a set time, then cuts off)

My -7 has the starter interlocked with the mag switches ... I wired it so that left mag (impulse mag) is ON and right mag is OFF to enable the starter circuit. My button's on the panel, but easily could be moved to the stick. Any other mag config will disable starter circuit.

Just curious, what is the rationale for having it on the stick? I don’t see the need to have a hand on the stick while starting and definitely don’t need it during any emergency.

Since I used relays to switch all loads, it was easy to build an interlock on my Master switch. YMMV.

With a nosewheel, no. But with a taildragger and a typical big throttle, fuel injected hot start - the stick better be hard in your stomach or you will be on your nose in a second.

I set my-8 up with start switch on the stick and com button on the throttle. I have an arming switch on the panel with a LED warning light on when armed. Works very well on a taildragger.

Not difficult to trap the stick between your legs during start (that's what I do in my RV-8), and if you're running the engine up to full throttle immediately post start you're doing more things wrong than not having the stick back.

That said, I've had the engine in the RV-8 at full throttle without the tail getting light...but I've only got 180HP and live up at 6000' DA most the time, so I likely have less power than the majority of folks are dealing with.

That said...none of the WWII airplanes have starters on the stick, and they are more likely to nose over than an RV I'd suppose.
