    Subject: RV6 Control column
    --> RV-List message posted by: "Clive Whittfield" <cazw@ihug.co.nz> Listers Trying to set up the control columns per the instructions and refering to DWG 41 I find that I cannot get the sticks parallel while maintaining the stated measurements. The 19 inch bolt centre measurement for the end bearings on the F-665 seems a little too long. With everything in place tops of the control sticks slope slightly inward ie the distance between the tops of the stick is about an inch less than down near the pivot points. I have wound the rod end bearings in as far as they can go, and have double checked all measurements making sure the weldments are correctly manufactured etc, and all seem to be correct. The easy fix would appear to simply shorten the F-655 to suit, but am reluctant to commit to that option without some advice first. Has anyone else struck this or am I missing something?

You can change washers inboard or outboard to modify the angle of the dangle. Actually, you should first check that the spar attach brackets are correctly mounted...... After setting mine up it came out parallel - but I don't have enough threads left to turn either heim joint a full turn inboard...that tells me that they're close right out of the box.

It absolutely does not effect the rules that apply to other aircraft. If someone buys an RV-12, they will have a choice to certify it either as E-LSA or experimental, amateur built. In either case, it can be flown by a sport pilot because it meets the definition of a LSA. The definition of an LSA is based upon certain performance parameters, weight, and number of seats etc. It is not in any way defined by the certification it receives, ie - standard, E-LSA, S-LSA, or experimental, amateur built.

    Subject: Heavy Wing
    --> RV-List message posted by: "DAVID REEL" <dreel@cox.net> I have a VERY heavy left wing on my RV8A. Full aileron trim doesn't begin to correct it. I measured the flap angles and found the left flap to be 1 degree more up than the right flap. I also checked the wing incidence and found them to be within 1/10 of a degree of each other. So, I'm contemplating cranking the left flap down 1 degree and fly to test. However, I thought I'd ask if you thought that was too big a change to make all at once from your testing experience and in addition whether a single degree would be likely to make a big difference. A related question is how can I tell whether the flaps are in neutral trail more accurately than with the wing template. Maybe I should be raising the right flap? With the wing at 0 degrees incidence, it would seem that neutral trail on the flap would be a specific number of degrees as measured, say, across the top of the flap. Do you know of such a number? I've never seen anything like this on the list but I bet Vans design computer could spit this right out. This would make it much easier to set the flap angle.

    Subject: Re: Heavy Wing
    --> RV-List message posted by: dsvs@comcast.net To set the flaps you need to first set the ailerons at 0 degrees relative to each other. Do this by setting a straight edge along the tooling holes of the outboard wing rib and align that with the trailing edge of the aileron. Do this fon both wings independently. After the ailerons are set leave the straight edge attached to one wing and set the ailerons to neutral (in alignment). The flaps in the up position should align with the ailerons at this time. Another thing to look at is that the flaps and alireons are not at an angle to the wing inboard to outboard. Hope this helps.

    From: Jeff Point <jpoint@mindspring.com>
    Subject: Re: Heavy Wing
    --> RV-List message posted by: Jeff Point <jpoint@mindspring.com> Another thing to look for is the height of the aileron relative to the wing. Despite my best efforts, my left flap was 3/16 or so low at the outboard end. The ailerons can be set to the proper angle and still cause a heavy wing. A new aileron hinge and about an hour of worked cleared it right up. Van's has a good write-up on the heavy wing problem. http://www.vansaircraft.com/pdf/Wing_Heavy.pdf Jeff Point RV-6 Milwaukee > >

Still after a about 110 hrs in her, if im flying along and see something I want to circle over, I pull a heavy turn and next thing I know Im climbing 500' min. Anybody have a fool proof method of automaticly setting the stick to prevennt this? (I was once know as a very presicion pilot)

Dave, While flying, if you bring your flaps down just a hair, do you notice any difference in the wing heaviness? I'd personally be more inclined to bring the right flap up a hair rather than move the left flap down. Of course, this makes a lot of assumptions about your exact installation. Do you have any "guru" builders in your area who could come have a look? The other suggestions have been great, and I've read here on the list that you can get a lot of effect from the aileron squeezing method. Good luck - and let us know what you learn! -- Mickey Coggins http://www.rv8.ch/ #82007 finishing do not archive
