Are you sure it's hitting the filter? Mine was sticking in the sleave so I greased it and worked great after that.

So if someone tells you to use the FG linkage .. just make your own then , it will be alot cheaper and can even grab a few Thousands of a inch thicker rod to help with flexing also .. use aviation linkage at your LHS

Good Luck m8

Hi Whizzy,

I had some stiction problems with mine when I first set up mine, and it was because the slide on the throttle arm was not horizontal, so when freshly oiled it was fine, but within a few minutes of running it would start to stick.

My solution was to fit a spacer between the servo arm and the slider, no problems since.

What filter are you using, I've got the MCD one with a D&D pre filter, and whilst the linkage is close, it's never caught up.

I'll post a piccy later

That makes sense, as the RN filter is wider than the MCD one.

Here's a pic of mine to show the spacer.

hi iow basher i did the mod on sunday using the fg stuff works a treat and for a mere £5 each i think it was worth it although i already had the stuff here to do it and when the mcd one was removed i felt it sticking so hope that resolves the problem
