I drilled a hole in a pair of airscrews then soldered in some 1mm clutch cable. Made the cable long enough to come to side of frame. Then made a little knob for each end. Now i can adjust the mixture anytime.

Funny thing is, when i mention this to Matt at tyga, he sent me a pic of same thing that he did years ago.

This is without a doubt the way to go. Perhaps some motivated entrepreneur can make some for a small profit.
