    Subject: Rudder Trim
    --> RV10-List message posted by: "John Kirkland" <jskirkland@webpipe.net> Hope Randy sees this now that there's a flying airplane in the group. I was wondering if anyone that has flown one of the RV-10's has thought that it needed a means of rudder trim? After flying 4.2 hrs XC yesterday it occurred to me that stepping on the ball during climbout gets old after a while, and I like the Cessna 182 rudder rim wheel so you can center the ball once climb is established and you're not so busy. Not sure if anyone would notice this in a quick demo flight, but by now I'm sure Randy would know! John Kirkland #40333

First, you're not going to be spending a lot of time climbing to altitude, and second, rudder pressures are so light that the average Joe's size elevens with just the slightest hint of pressure will center the ball. The RV10 rudder is very sensitive (even more than my -8) so you don't have to stomp on it to get the desired effect. My one flight in Van's -10 was just terrific and not once did I feel a need for any form of rudder trim. I guess I'm just used to not having one so the thought never crossed my mind! For level flight, yaw trim varies from airplane to airplane. A small rudder tab of either sheet metal or glued on balsa trailing edge stock from the hobby shop does the trick very well. My -8 flies ball centered in level flight with feet off the pedals. The earlier RV's (4's, 6's) often have small tabs attached from what I've seen over the years. This helps trim out the plane in climb and cruise, but has to be compensated for in descents. It just depends on what's important to you and what you have become accustomed to in the airplanes you typically fly. I'm sure Randy will have some valid input on this in due time. Lucky guy. ;) Brian Denk RV8 N94BD RV10 '51

    Subject: Re: Rudder Trim
    --> RV10-List message posted by: Tim Olson <Tim@MyRV10.com> That was just what I was thinking too, Brian! At over 1500'/min, I don't expect to be climbing very long in the -10. In fact, that was one of my biggest selling points. I fly with my wife and kids most of the time. We're always trying to get to a smooth altitude. Sometime's in the summer it's a hassle trying to get to 9000'. I don't expect to be waiting too long in the -10.

    --> RV10-List message posted by: "John Hasbrouck" <jhasbrouck@woh.rr.com> If you look at both of Vans -10s they have a fixed wedge screwed to the trailing edge of the rudder on the left side I think. I assume this was to provide some trim for right rudder deflection. Anyone else notice these..... John Hasbrouck #40264

    Subject: Tank skin to baffle rivet question
    From: "John W. Cox" <johnwcox@pacificnw.com>
    --> RV10-List message posted by: "John W. Cox" <johnwcox@pacificnw.com> This is a great time to expand the discussion to what causes a line of smoking rivets seen over time. Also covering the correct treatment of metal prior to final exterior paint. Stein are you there? John Cox -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of John Jessen Subject: RE: RV10-List: Tank skin to baffle rivet question --> RV10-List message posted by: "John Jessen" <jjessen@rcn.com> One question that a friend of mine raised, which I couldn't answer, has to do with a slight variation of this. She wondered whether or not the primer's ability to provide its protection is compromised by the rivet. That is, when a rivet is seated, does the primer around the rivet head "break," thus creating a, I would imagine, microscopic weak point where moisture could invade. This came up in my, seemingly, never ending discussion about which primer approach to use. The question about epoxy raising the rivet head, and/or the rivet head "cracking" the primer were two questions lacking an answer.

    Subject: More Missing QB Fuse Parts
    --> RV10-List message posted by: Tim Olson <Tim@MyRV10.com> If you have a QB fuse, you probably should check the quantities of some of these parts. Some are not even listed on the inventory sheet. If you have more to add to this list, send it on and I'll perhaps post this on the website. Front Floor panels: If you didn't get the floor panels, you probably didn't get the hardware needed either. They will send that with them. I was still short 8 CS4-4's in that hardware pack. Also, there were no K1000-3 nutplates to put under the front legs of the gear brackets (the ones that bolt through the floorpans). Hardware bag 1455 includes 2 K1000-3's, but you need 4 to do the floorpans. You probably should get a couple extra K1000-3's because if you were short already by 4, who knows how many more will come up. I got tipped off from another lister and found these missing too: For brackets holding fuel/brake lines under front seats: AN515-6R8 (qty 8) AN960-6 (qty 8) AN365-632 (qty 8) I found you will be real short on the K1000-8 nutplates. They do include 40 in the hardware bags, but I found at LEAST this many required: P. 28-7 (6) P. 32-5 (2) P. 33-7 (8) P. 33-9 (5) P. 34-7 (4) P. 35-3 (8) P. 41-5 (6) P. 33-10 (24) That totals 63. How they missed by that far I have NO idea. AN257-P3 Hinge: I have a 3' piece, but you need to have about 3' for the 2 rear seats, and about 2' for the baggage door. I'm going to press on and cut my 3' piece for the baggage door and get them to send another 3' piece. MS21053-L08 None are in hardware list, but 4 are required on Pg 35-3. AN3-6A 4 are required per side....attaching the control bracket under front seats. pg 28-14. None are included in the inventory list. F-6114B and F-6114C: These are blocks that go in the rear baggage wall...I think for friction prevention where the seat belt cables come through the rear wall. 2 each are required on P. 33-10, none are in inventory. LP4-3's: They send a quantity of I think 275, but I am now running out. I can see that I used 196 on the rear seat area, + 39 in the baggage area for misc. panels, + 14 in the rear passenger floors. Then you get to P. 35-3 to put the bottom on the bracket that holds up the rear seat and it requires 50 right there, pushing you over the top. You will need to buy a Baggage door lock ES A-510-2K with Mag Switch or you won't have a way to latch your baggage door. On the front section, right above and behind the NACA vents, there's a "wire cover" that gets screwed down. There are 3 spots for nutplates pre-drilled in the longeron F1040-L & -R. They hold down the wire cover F-1042G-L&R on page 35-7. My longerons are pre-drilled. I couldn't find the spot in the plans where these get drilled for nutplates, or if it's done at the factory, but, I also couldn't find out where the nutplates are installed, so I have no idea what type are supposed to go there. I'll have to call in to verify this. Hopefully this list will help you people with QB Fuselage's not get stuck at various points along the process. I am very frustrated that every time I went into a section, I ran into a barrier of a missing part or something that had a dependency. Then I'd start another section and go until I ran into another missing part. I would not be nearly as bothered by this if at least once in this process I heard of a builder that actually got contacted by Van's, and told "Hey, we figured out that your kit was probably missing these parts....if you check for these, we'll send you out some if they're missing". But, it looks like they just fix the quanties in the kits....and they let the previous buyers slide until they figure it out and complain. That bugs me a bit. I got QB fuse # 40, or is it #44....but I suppose that's still early enough on to be finding mistakes. Tim -- Tim Olson -- RV-10 #170

    Subject: Filling pin holes
    What's everyone doing/using to fill the pin holes? I use epoxy with mircro baloons. I don't mind sanding but this stuff is hard as a rock after it cures and a bear to sand. Of course I have filler over 75% of the working surface because I see pin holes everywhere. Can smaller holes be ignored because the primer will fill them later? I'm thinking there might be an easier way or softer filler available to speed up the sanding. Anh #141

    Subject: The impossible rivets - 1 won, 1 lost
    --> RV10-List message posted by: Tim Olson <Tim@MyRV10.com> I found 2 "impossible" rivets, and the solution to one of them. QB fuse, by the way. #1 is on the baggage door latch bracket that goes on the fuselage. There are 2 nutplates to attach. 2 of those 4 rivets are not accessible by squeezer or bucking bar. I did, however, find that I have a very small flat squeezer set and I could drill a hole and enlarge with a unibit in the flange underneath the rivet, and get the squeezer through. I just don't know how else you'd do it. Here's a couple of photos. http://www.myrv10.com/N104CD/fuselage/20050530/RV200505260017.html http://www.myrv10.com/N104CD/fuselage/20050530/RV200505260016.html The other impossible rivets are on the very forward hole of the rear seat panels, on the sidewalls. There are holes that are completely inaccessible by rivet gun, or pop rivet tool. This photo shows the location, a couple inches NorthEast of the rivet set. http://www.myrv10.com/N104CD/fuselage/20050530/RV200505250013.html Short of drilling a hole through my seat bracket, which is NOT worth it, I can't find a way to fill that hole. The ones on the other side of the floor panel by the tunnel could be popped in from the tunnel side I suppose, but you'd have an ugle rivet sticking into the seating area. For now I'm just going to leave them empty. If I got desperate, I'd GLUE in a rivet for looks... then everyone would think I figured out the secret. :) Tim -- Tim Olson -- RV-10 #170

IMHO, I would NOT put ANY composite propeller on a 4 cylinder 4 cycle engine unless the propeller manufacturer has done a valid vibration survey. From what I have read from the people flying the Whirlwind propeller, I would guess that this hasn't been done. IMHO, if a 3 blade propeller is used in place of a 2 blade propelller and there is not a very noticable difference in vibration, then there is something VERY BAD happening with that 3 blade propeller. A 2 blade propeller has a 2nd order harmonic that does not occur with a 3 blade propeller. The 3 blade vibration level is VERY noticably LOWER than with the 2 blade propeller. And you don't need "no stinking instruments" to tell the difference. :-) "Stinking instrumentation" is required to determine what is happening along the blade.

I'm happy to be re-educated here but I thought the main reason for riveting the nutplates was to centre the plate and prevent rotation during bolt installation/removal (since the nut plate acts like a 'nut' once the bolt is tightened).

    Subject: Re: The impossible rivets - 1 won, 1 lost
    --> RV10-List message posted by: Tim Olson <Tim@MyRV10.com> Ron, It's not that it's a strength issue. The problem is, there are no provided countersunk pop rivets in 3/32" to fit the nutplate. It would be acceptable if you had them. The closest thing we have is the MK319-BS rivet, that is 7/64", so you'd have to drill out the nutplate to 7/64". That actually MAY work, but the nutplate wouldn't be as strong...not that it needs extreme strength though. It also wouldn't be as pretty. I don't know if everyone has one of those small flat squeezer sets, but it worked perfectly for the task...just took some thinking as to how to get to that solution. The squeezer set I used is only as wide as the squeezer shaft itself. it's come in handy a few times on the kit. You're right though, on nutplates, they don't need a heck of a lot of rivet to hold them. It's just an anti-rotation thing.

    --> RV10-List message posted by: "DejaVu" <wvu@mail.ameritel.net> I drilled the holes like Tim did, one under each "ear" of the nutplate, and back-riveted the nutplate on.
