Rotaxers,



I'm scratching my head trying to figure out how to substitute a conventional throttle with a throttle cable for the T-Handle throttle supplied with my kit.  I figured it would be easier to operate and keep the RPM at a cruise setting compared to the T-Handle.



My problem is how to connect it to the Bellcrank.  There has to be a way, but so far I've not figured it out yet.  The throttle cable is an ACS model with a friction lock.  The cable is about between 1/16- 1/8 diameter.  Surely there is a device somewhere out there that will work.



Any ideas?

Tommy,

     A picture or drawing of the part you want to connect and the place 

where you want to connect it would help us all help you to figure it out.  I 

personally would install a verner throttle cable.  This is the kind that you 

can push in or out for general usage or turn to get fine adjustments like 

when you are flying formation.

This is from our friend from Iceland, Johan, who has finished his very nice

I used a vernier throttle in my 601. It works very well. One thing about a vernier type throttle is that will make the second throttle useless because the vernier mechanism locks the throttle cable up in such a way that it can only be operated from the vernier. I couldn't see any way to make a second throttle function with a vernier on the other side so I eliminated the entire throttle system supplied with the kit and fabricated my own bracket to hook the vernier up to just the pilot's side of the panel. In a pinch, the right seat co-pilot can switch hands on the stick and reach across to operate the throttle. Since all take-offs and landings will normally be flown from the left seat, this arrangement presents no problem.

Tommy, I converted mine to the ACS throttle as well. It was actually quite

easy. I made a part from aluminum stock on a lathe to adapt the wire to

the bell crank.



I'm not the originator of the idea however, Johann in Iceland is. Have a

look on his 701 website for pictures of the adaptor here:

Great idea from Johan,  

My comment,  I will just add a little drop of Locktite to the bolt tread...  Will not hurt and will prevent loose from vibration.

Hello Tommy.



I used the Vernier throttle from ACS wit the solid wire end, A820 on both sides. I started with the throttle on the left side, and then decided to install it on both sides, because it was the perfect setup.

The old T from Zenith is still on the right side in the picture on my home page. 

Did not like that long stick because it was hard to control.

If you need the part to attatch the cable to the steel rod, I could send it to you. Just contact me off list with your address, and I will ship it to you.



Best regards,

Johann G.
