Geoff Combs is local to me so I could see what he did with the door seals. Another good source is Ivan Kristensen. Take a look at Ivan Kristensen's photo album. http://ivankristensen.phanfare.com/2292606 On the cabin door album, about half way through the photos, he has a video that will show you enough information to get you started. I flew with Ivan a couple weeks ago and his RV-10 turned out great. I'm not sure what you mean about too snug at the door pin areas. I didn't have any issues there at all. It sounds like you may have more of the rain gutter left than I have. Without photos, it's hard to tell. My door seals will go around 100% of the opening. The same is true with both Ivan's and Geoff's. There are many others that have been successful too. Les Kearney wrote a word doc explaining how he did his doors. I highly recommend Sean's safety latch and strut attach bracket. Both will make your life easier. bob -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of johngoodman Sent: Sunday, September 19, 2010 8:27 AM Subject: RV10-List: Re: Door Attach Struts --> rleffler wrote: > It drops the mount point for the strut down about 1/4" so that it > clears the McMaster-Carr door seal. > > bob > > -- Bob, You're the guy I want to ask - how much sanding did you have to do to get the doors to close properly on the door seals?

The RV-10 doors are definitely the achilles heal of the plane. You should not need a ton of leverage to close the door handles and I think this would be an unsafe sitution or when you are out at some small airport without cell coverage you will bust your door up and be stranded. You may have tried all these but here are some recommendations. Some things I have seen are door pins that bind going in the cabin guide and structure, make sure the pins are extending going in parallel to the outside skin and level through the guide. Run a 7/16 reamer through your door guides and structure on the same plane as the pins extend. Super tight seals (like mine) that you have to relieve a little. I ended up squishing my seal so damn tight that the door would flex, I opened the reveal from the door to the cabin lip by 1/16 and it made a huge difference and the seal is still really squished. I can't remember if you bought my door pins. Of course you think I am trying to sell them BUT the angled pins and Delrin door guides make a huge difference with ease of door closing. The delrin acts as a good bearing surface and the angled pins allow a full 7/16 of mis-alignment. Bullet pins only have 7/32 of misalignment allowance.

I also have flush handles and had one seize for the same reasons you have experienced. Here are a few suggestions that might help: 1. Get some white grease or similar and use liberally on the door mechanism. Be sure to get it into the rack and gears. 2. Carefully disassemble the flush door mechanism (there is a small ball bearing in a recess with a small spring so don't loose them. 3. Grease the inside of the flush door handle. I found that there is a huge amount of internal friction in the door mechanism. A little grease makes the door action very sooth and light. If there is any significant resistance to operating the mechanism when the door is open, find the source and fix it. I made my door pin holes on either end of the door slightly oversize as I found that they were binding there as well. You may also want to see if the pins are not exactly running straight through the guide blocks. If the rack is a bit off center from the pin, you may find putting a slight bend in the pin will allow it to travel straight through the block and not be pushed up or down by the rack (which can cause some binding). A bit of grease on the guide blocks helps as well. Another factor that may cause a lot of problems is the amount of pressure required to close the doors. I found that if the doors require a lot of pressure to "Pull" the doors into place so the pins engage, then it takes a great deal of effort to insert the pins. I moved my door frame inboard by about 1/8" on the bottom to reduce the pressure on the door seals. The amount of effort required to pull the doors in enough for the pins to engage is not quite light.

Now they close really great. However, I believe that after a few months I will replace the Vaseline with some type of good quality white grease. Also, my doors are completed with the McMaster Carr door seals. Conrad Booze in Georgia -------- Conrad Booze Sr. Engineer P. O.

Two albums on the subject listed below. Some observations along the way: 1) Regarding the door seals: I went the McMaster route, however, when I got done trimming the door jambs back to the proper depth to allow for the bulb on the seal, I went one step further. The door jamb profile doesn't naturally match the U shaped profile of the seal, so the seal would be prone to slipping off without some type of adhesive. I decided to use a scrap piece of the seal profile as a mould to add a filler/epoxy profile back to the door jamb that exactly matches the door seal. I took a 2 foot section of door seal and injected a mix of west system epoxy and structural filler, (used the cake decorator bag trick to fill the U shaped profile) then installed the seal section on the door jamb and let it set- up. Remove the seal and repeat 6 more times around the door jamb until the whole thing has the exact mating profile to the seal. Now the little retaining tang inside the U shaped seal channel has something to grab hold of and the door seals hold onto the door jamb very well. 2) Regarding filling and sanding around the windows: The electrical tape technique for masking off the windows works great, however I found with black electrical tape it was very hard during the sanding process to distinguish between the tape and the filler. I switched to orange electrical tape, a huge improvement!. As I'd sand the filler down to the tape the color of the tape line would really stand out providing much better guidance in terms of sanding depth onto to the tape. 3) Regarding vacuuming up the filler dust: Whilst all this sanding and filling is going on I found that when I would clean up the plane with the shop vac I'd develop an enormous static charge on the plane, then when I touched it, wham! the mother of static shocks would almost knock me down. Solution, I grounded the plane!. Problem solved. I just took an extension cord with a metal box on the end and laid it in the tail of the plane. All better. http://picasaweb.google.com/rcnewman64/BodyWork# http://picasaweb.google.com/rcnewman64/DoorsLatchesSeals# Bob Newman TCW Technologies, LLC www.tcwtech.com builder #40176 ________________________________ Message 11 ____________________________________ Time: 07:22:40 PM PST US From: "DLM" Subject: Re: RV10-List: performance The autopilot is very sensitive; I can manually trim so that the electronic trim wheel disappears but shortly thereafter it reappears due apparently to slight pitching of the aircraft. ----- Original Message ----- From: "Tim Olson" Sent: Sunday, September 19, 2010 3:10 PM Subject: Re: RV10-List: performance > > Your autopilot was out of trim...did you notice it when you were > flying?

I find that if I trim for hands-off, and set the autopilot, it stays pretty much 99.9% of the time until descent with no out-of-trim indication. Very occasionally I get it, but so rare that maybe enroute cruise I've only seen the indicator a dozen or 20 times in 650+ hours. It does come on during descents sometimes though if I don't re-trim. Do you have safety-trim or some other speed control system that allows you to get the trim real precise? Maybe for some reason your AP servo's sensors are extra sensitive?

For around 600 hours I had no lubrication on my pins and guides at all. I was totally shocked at the difference made by simple lithium grease on the pin ends and guide blocks. There may be better grease solutions, but I just had some handy and decided to give that a try. It was amazing how smooth it was after that. Now I wish I had done the rack gears and stuff.

I have the HIDs in the wingtips and they focus and merge about 50 feet ahead of the aircraft. During taxi this morning before daylight I followed the taxi lines over a rubber chock set. After examination the nose pant rear fiberglass is cracked and I will have to repair. Still to be determined : whether this is due FBO stupidity /carelessness or deliberate by some disgruntled airport visitor. The chock was left on the centerline about 50 from the start of the movement area point. The location is the only path between the runway environment and the majority of hangars and covered tie downs. Authorities are still trying to determine why they were there.. Of all the places to drop these chocks, if unintentional, this is the only place on the airport guaranteed to cause damage in the dark. A nose mounted light might have helped; the wingtip mounted lights were disadvantaged by a 90 degree turn prior. ________________________________ Message 15 ____________________________________ Time: 09:06:53 PM PST US From: "Pascal" Subject: Re: RV10-List: Doors and body work 3) Regarding vacuuming up the filler dust: One thing I will caution is don't use the vacuum when brooming will work. The fiberglass will literally destroy the shop vac. In my case the dust was fine enough to clog the filter and cause the vac to overheat or something, it literally started to spark and smoked and that was the end of a very reliable vac I had for years. If one is going to vacuum, and I do when needed, clean the filter often Take it for whatever it's worth.
