Mcfarlane throttle

[jiott]

I bought both the medium and the light McFarlane throttle springs for the 912. I tried both and definitely like the lightest ones the best.

Not sure what springs they send with unit do you have a part number for the lighter springs? Will I be able to set it up appropriate with springs they provide?

Not sure what you mean by "they" provide. Rotax provided springs are quite heavy. Don't have part numbers, but if you go to the McFarlane website for Rotax 912 parts, you will see that they offer two throttle springs-get the lightest one in my opinion.

I ordered the throttle and was wondering what springs come with the Mcfarlane cable. It actually ships with 2 springs that have lighter pull than the Rotax and conduits. You mentioned even a lighter spring and that is what I was referring to. Thanks for your help here....

after flying with a push pull cessna type throttle and trying to find the sweet spot. this mcfarlane is the answer. i used the light duty srings to assist and what a breeze.Actually fly and apply friction and still use the veneer feature.
Super nice to find that sweet spot in throttle settings. Higly recommend. I purchased from CPS Chief no longer sells them. A bit more money but I got it.
Any questions ask...

We installed a McFarlane vernier throttle in my 7SS project. It comes with a set of the lighter springs for the Rotax. Seems to be a very high quality item. Needed to trim about 1 foot of the cable shroud to fit. Use caution not to pull the throttle handle out too far before trimming cable shroud. Little parts will fall out of the throttle mechanism. Not hard to put back together as long as no little parts are lost. Used a dremel with a cut off wheel to very carefully cut through the cable shrouds at the desired lengths and not nick the cables inside.

Anyone interested in a Vernier throttle cable off a model 7? It has the push button and twist adjustment. I bought a different one . It worked but I was not used to the button. I see McFarlane has a rebuild kit for it available as it is about 14 years old.
