mixing arms

[kahn10]

when i first got my hurri i found that the upper mixing arms?tilt arms? ok the little seesaws on the grips and the mixing arms on the washout were kind of wobbly.the problem being when i tightened them up till they didn't the upper ones bound on the grips and the lower ones bound on the washout block plus the screws distorted the washout block so it bound on the mast.i loosened them off slightly so they didn't bind(but wobbled) and left them like that for a bit.i just made up some brass shims like the ones at each end of the flybar seesaw and put them on on each side of all four mixing arms. there are plastic stand offs on all surfaces but they don't seem very effective.and got cap screws that were slightly shorter for the washout. wicked difference now.everythings cranked up tight with no wobble the heads floating like a butterfly and the washout mixing arms are tight as with no binding anywhere.worth checking out and doing if you have plastic mixing arms and grip seesaw things......
