Default New Throttle Handle

While avoiding yard work work this weekend, I decided to make a new throttle handle. I never liked the way the original felt and the fact that it wasn't centered over the quadrant. This handle is made from some 25mm OD 23mm ID carbon fiber tube from eBay. The end caps were turned from some 1" 6061 stock and there's another piece of it turned down and tapped 10x32, bonded inside the tube to attach to the throttle lever with the same hole as the original. Works great and has added 5kts and reduced fuel flow by 1.5gph.

Hey Jim, did you update your weight and balance - or just the performance section in your POH?

Now.... While you're at it. I would mount a little TO/GA button on that throttle handle. For sure that'll add another 2kts. ;-)

Herman - I had to update both, the new handle is a whole Kilo lighter than the old one!

You know, I did think about that, even left enough room for the wire inside the handle. Just got to think of something to replace the existing TO/GA button. Chaff maybe?

I would put this in there. https://www.steinair.com/product/pus...pdt-momentary/ Drill a hole in the left handle end so your thumb can get to it, but recede / countersink it so you don't accidentally activate it.

Default TO/GA Switch.

The TO/GA button already installed is a DPST. Dual poles are required to isolate the ground between the GTN650 and the G3X. I hadn't seen that SteinAir had a DPST micro switch until you pointed it out. The TO/GA function really is nice, I've used it many times practicing approaches, surreal the way that Garmin A/P flies the missed...

Paddy, that's an awesome home brewed modification! I'm sure it required going back into Phase 1 with that much change to the air frame. Ha!
