From: Galin Hernandez Since my plane is down until the engine overhaul is finished I have been checking different things I have always put off. One is that the airplane has always flown left wing low. Today I set everything to neutral and found that the right flap is slightly lower when the left flap and both ailerons are neutral. This would explain why the airplane flies left wing low. Rich told me a long time ago it was an easy adjustment, but he knew what he was doing. So now my question is how do I raise just one flap? Can somebody provide instructions, preferably with pictures of how to slightly raise just the right flap? Thanks. Galin ________________________________ Message 2 _____________________________________ Time: 11:10:51 AM PST US From: Robert Reed Subject: Re: KIS-List: Flap position adustment? Galin, >From the Builders Manual on my website. I can tell you that it is a trial and error process but the following should explain it. SETTING FLAP POSITION If the small plastic square that rides in the flap actuation "track" is deliberately drilled slightly off center, it can be a possible adjustment mechanism to assure symmetrical flap position. A side offset of roughly .020 in. and a vertical offset of .040 in. will give you up to .08 inch of corrective travel if required in .02 in, increments by relative rotational position of the blocks on each side. More severe corrections can be obtained by greater offsets, but the actuation arm may interfere with the sides of the "track." When the two flap sides are equal, it is a simple matter to adjust linkage length to place the flaps in proper position for normal flight (as checked by the airfoil template." Actuate the flaps through full travel, and clear any interference problems and assure free and positive operation.

I don't think there is a simple way of adjusting the flaps relative to each other on the TR-4. The easiest way is to bond on a little shim on the trailing edge of the wing root fairing so when the flap is retracted it will contact the block and hold the flap slightly down. I would start with a 1/16" block. I used phenolic in my TR-1. I have a 1/8" shim for my right flap. There is enough flexibility in the flap mechanism to absorb it.

From: Alfred Rosa Galin, You would either have to adjust the angle of the actuator arm on the right flap tube, or adjust the angle of the channel guide that the arm slides in.

This is one case where a change from the plans that I made were beneficial (and logical). I was concerned about unequal flaps during construction, because of the feedback I got from an RV builder after his first flight -- "it was a little wing heavy, so I took a couple of turns out of the flap actuator and then it was perfect". Hmm I thought, I can't do that. I then decided to do a split flap actuator at the center of the plane. Purchased a second arm that goes in the center, and mounted it beside the regular arm, with the torque tube cut in half. Then I made a special push rod that had two bearing ends to attach to the two arms. Then turning the bearing ends independently would allow slight changes to the flaps. Sure enough, after 1st flight I had to make a couple of adjustment. I thought I sent picture of this to Bob's web site. Bill Schertz To disconnect? Can you remove the bolts at the end of the torque tube so that the flap can rotate further down to free the block? -----Original Message----- From: Galin Hernandez Sent: Tuesday, September 30, 2014 1:15 PM Subject: Re: KIS-List: Flap position adustment?

Galin, Check out Bill's modifications by clicking on the following Flap Modifications You can try disconnecting the actuator to the interior actuator arm and see if you get enough movement otherwise you may have to remove the bolts on the actuator arm that connects to the flaps.

Galin, Not sure on your plane. I have set mine up with removable hinge pins so I pull three pins and the flaps are free. My first shot on yours would be to disconnect the push rod from the flap actuator arm on the inside of the plane. This should allow the flaps to drop down farther than they normally would and hopefully they would allow the outside actuator to come clear of the channel. If that doesn't work the only choice would probably be to remove the bolts that connect the outside actuator arm to the torque tube. Those may be rather difficult to get at and remove so I hope the first alternative works. Removing the entire flap would be the last resort since it's a bear to reinstall with all those screws. All I can say is GOOD LUCK!!! Bob PS: I got to work on my project this weekend for the first time in 10 months. If you can call washing all the dirt off and cleaning the hangar working on the plane. Spent most of time cleaning but did spread thin application of filler over entire plane in preparation for sanding and primer. Next weekend I will proceed with my most favorite of all ......SANDING!!! ________________________________ From: Galin Hernandez Sent: Tuesday, September 30, 2014 5:12 PM Subject: Re: KIS-List: Flap position adustment? Okay let me try that first. Can you unscrew the flap at the hinges without too much problem?
