Steve, this may be dumb question category, but I need clarification on your comment:

Yes, I do have the friction lock as tight as it will go, but I find in that configuration, with my cable at least, I get the best of both worlds. It only moves when I want it to, but I can move it without much effort.

Does this mean you can move throttle w/o unlocking? Or do you have to precede the move with release of the lock?

Mine is number 336 and I have no problems so far. I just tighten it to the point that is stays put and at that setting I can still make minor or major adjustments. This is hands down, the best flight video I have seen. Even though I live on the opposite side of the country, that is my favorite part of this grand country that we call home. Thanks for making it. It really is the coolest video I have ever seen!

Dick,

Yes, I can move the throttle without unlocking it. With the friction as tight as I can get it, at leaset with my fingers - not using pliers here - I can still move the throttle without excessive drag. So I don't change the friction setting (ever) and don't really have a creep problem (at least not throttle creep).

Mine as I have mentioned before has no creep, and I too just set the friction and fly, without any inflight friction adjustments. If I unscrew the lock ring the knob is slowly pulled in by the carb springs.

Last time I was in the plane I unscrewed the throttle control's lock ring to see what was actually causing the friction and saw two leather washers in there, one conical shaped, and one flat.

Although mine is not any issue for me, I am curious why others are not the same. My throttle is a Mcfarlane and says not to oil. Are all of them Mcfarlane? Has any one called Mcfarlane and asked about this? Anyone with problems oiled theirs? It would be neat if two planes could get together and compare hardware - One that creeps, and one that doesn't.

Default I have seen - -

3 other planes that were newer, and they did have a different throttle. I flew one of them recently, and did not do other than I usually do, unlock before adjusting. It was different than mine, but it did not slip, so not sure. I have not asked that owner how he adjust his throttle, and may try to next time I talk to him.

Steve, thanks for the clarification. This thread gets more interesting by the hour. Next flight I will see if I can operate the throttle w/o releasing the lock. If it works I guess we can call that pilot controlled creep?

Default Throttle Spring Orders

All of the throttle spring orders are being shipped out today, via USPS.
There is one exception, I still do not have an address for Mark Henderson.

Don't forget to modify your new springs according to Joe Gores posts.
Care should be taken to prevent stresses with tight kinks and tool marks.

Again, my email address: tomscub@earthlink.net

Good luck guys, Tom

Mission Accomplished!

Thanks Tom! Perfect timing! My engine will be here in time for Christmas. My son's coming home for the holiday from Edwards AFB to provide Engineering Support

Default McFarlane Aviation

FYI

I contacted McFarlane Aviation, which supplies the throttle control and this was their reply:

" The throttle springs that come from Rotax are two strong of a pull to be used with a friction lock control. They are more suited to a non locking throttle control. I will send you two new throttle springs to install. This should take care of the throttle creeping problem you are having. I will also send you a throttle control friction lock service kit. Just in case you are still having trouble after you install the new springs. "

Default McFarlane's Memo

Now you tell us.
Seriously, let us know what you get, what the part number is, and how they compare to the ones that I just sent out.

Tom
