So, if it would fit in as a retrofit, I would be interested in one of yours,

PM sent. Of course, anything can be retrofit with enough labor and $$$! The #10 c/s attach fastener pattern is ~2 9/16" W x 2 11/16" H

$265 ea.

Our lever guides are delrin; the levers are SS; the friction lock is a SS spring. Very smooth action, the friction setting STAYS SET; and it won't corrode when used in formation (sweaty hands, ya know). I put a dab of light machine oil on the throttle lever (just a bit less friction) so formation work is easier.

Carry on!

PS Smokey's setup (single lever + 2 verniers) is a good one too, esp for fine mix adjustments -- BTW didja notice those rear rudder pedals? That's using your head for more than a hat-rack!

Here's a better picture of the throttle in N8RV. Since I had to lower the mounting to accomodate the size of the throttle lever, I had a row of rivets to cover ...

I can toss in a thumbs up for Mark's throttle quadrant--I have one in my -8 and it is one of the things I would do again in a heartbeat. It looks good and works very smoothly.

That's sweet. I was thinking of retrofitting delrin guides onto the Van's deluxe unit, but since you've already done it...

Mark- How wide (thick) is the unit? What is the current price? Are they on your website?

Mark,

Why did you put the levers in that order ?

Normally, the prop sits next to the throttle and the mixture is furthest away.

Looks a very nice unit - may yet be tempted.......

I don't see a reason why the balls for mixture and prop couldn't be easily swapped putting the mixture on the outside.

1 7/8" wide; you can order direct thru my email:

Carry on!

PS the shots with the knobs misplaced are in error - the knobs are placed correctly. I sent one to Fatboy for test fitting of his throttle lever knob - have not heard if it fits or not. I hope it does!

Carry on!
Mark

Default FatBoy meets F1Boss



Hey guys,

I've talked Mark into letting me sell his quadrants. They are soooooper smooooth, to say the least. No sticking whatsoever, and same pressure throughout the travel range. All 3 levers are identical in sensitivity. Drive down the tension nut where you want and throw your tension knob out the window. Mark testifies that no amount of vibration is causing slippage.

See my site for details -- I take the FatBoy grip, rework his throttle lever, and voila, you have the "FatBoss1". Keep going through Mark of course if you don't want the throttle grip on steroids, switches and all that, but I have to say, this is a quality product for sure. More pics/info at my site:

http://www.fatboythrottles.com

Flyeyes -- Just wondering how you mounted this in your 8? I'll post notes and other folks' install stories for reference on the site. Doesn't look too difficult, as it drops in clean, just need to tweak the attach hole placement a little.

Take care all -- Andy

Mine isn't standard, as I have relatively short arms, and don't like the stock throttle position. Mine is moved back and inboard a bit, and I would do it exactly the same way again.

here and

here

I'm very interested in your grip--would it be a drop-in replacement for my current throttle lever?
