Tail shake? From: "3benny3" How much if any play (can pick up rear of wing by rear mount 1/4in) play is in the castle nut the bolts universal to the fuselage frame and from universal to wing. Another notch on the castle nut is too tight, while where it is, is to lose I believe. Thinking about using very thin washers to get a "half notch" on the nut. Anyone else have play here, if so how much? On another note, seems like everyone's horizontal and vertical stab have some flutter/vibration in them. How much do you have if any and how much is ok? Anything you have done to help stabilize/stiffen this area? -------- 912 King Kolbra NC27 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=491440#491440 ________________________________ Message 3 _____________________________________ Time: 08:22:14 PM PST US Subject: Kolb-List: Re: Rear wing mount universal fitting play? Tail shake? From: "Richard Pike" Not exactly sure of what your question is asking, but here are some things I have learned: You can scrounge/create a very thin washer to put under your rear universal joint big castellated nut and get the play down to very minimal. You can fit as many washers as you need around the fitting that comes out of the wing root rib & joins said universal fitting to take up virtually all the slack. Keep fooling around with it, while mine is not totally tight, play is probably less than 1/16", and in flight, is unnoticeable. If your tail cables are tight, flutter in the horizontal stab will be unnoticable. All Kolb vertical stabs/rudders have slow pulse flutter in them, if you take your feet off the rubber pedals the rudder will start to flap. So keep your feet on the pedals! Or put a counterweight on your rudder similar to what Kolb sells for the ailerons.
