Thank You Ray Doerr 40250 N519RV -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of Larry Rosen Sent: Saturday, May 12, 2007 9:13 PM Subject: Re: RV10-List: Additional item to check at condition inspection time. Ray, How much engine sag did you experience? After how many hours? Larry Doerr, Ray R [NTK] wrote: > > I'm in the middle of my rolling condition inspection and one of the things I did for the Firewall Forward was to shim the two top engine mount bolts because initially when I did the cowl, I allowed a little too much (5/16") for engine sag. So I thought that after 245 hours on the plane the engine would have sagged enough to just correct the rest of the spinner alignment by shimming the top engine bolts where the engine mount meets the firewall. Two steel washers measuring 1/8" thick on each side did the trick and the spinner matches the top of the cowl perfectly now. Well with this done, I buttoned up the cowl and went for a test flight. Everything was fine for engine run-up and off I went. At 2000 AGL I leveled off and adjusted throttle and prop to 20 squared. While screwing out the prop, at about 1" out it started to get a lot harder to screw out. I kept going because it wasn't too bad yet, but then all of a sudden the engine went from 2300 rpm to something like ! 10! > 00 or so. I immediately started to screw the prop back in and headed back to the airport. > On my way back I had a few moments to think about this and figured it was the prop linkage hitting the upper air dam. What had happened is the rod-end was up inside the air dam when the prop is fully in, but once you screw it out about 1", it gets to the point where it was hitting the cutout in the air dam, then as I kept screwing it out, it did nothing to the RPM until it finally popped out on the underside of the air dam and this is when the RPM went from 2300 to something really low all at the same time. Once I was back on the ground, I looked at the rod-end bearing at the governor and sure enough, it was hitting the air dam. Since I shimmed the engine by 1/8", it not only dropped the engine at the spinner, but it also moved the engine forward just enough so the prop linkage was hitting the upper air dam. A stupid thing to overlook on my part. > Anyway, I thought I would share this with everyone so they check the clearance of the prop linkage as it goes up through the air dam at there condition inspection. This is important because as the engine sags in time, the clearance you had at first flight may be different now and you may need to remove a little more of the upper dam to have the proper clearance. > > > Thank You > Ray Doerr > 40250 > N519RV > > > ________________________________ Message 2 _____________________________________ Time: 06:18:47 AM PST US Subject: RV10-List: N-numbers From: Of course, you could be a lot more creative if the US was like a lot of other countries and used all letters instead of numbers. For example: G-SPIT (British-registered Spitfire) G-FAST (some sort of jet) And a favorite I remember seeing G-NADS Try to get the FAA to go along with that one! Notice that the airlines do buy up blocks of numbers so they can have N-numbers like: N987AA (American Airlines) N342NW (Northwest) N404PA (Pan Am, rip) TDT 40025 Tim Dawson-Townsend tdt@aurora.aero 617-401-2522 ________________________________ Message 3 _____________________________________ Time: 07:05:45 AM PST US From: "Chris Hukill" Subject: RV10-List: NIKE G5 They didn't roll the plane, they shut down the left engine to depressurize the Combined hydraulic system, so they could re-sequence the gear, that had jammed. No aerobatics required. The Gulfstream tecks talked them thru the event. I'm really surprised that the media got it wrong!

Smith" Hi All, I'm to the point of wanting to install antenna doublers in my airframe. The two options are placing one comm antenna under the rear seat and one on top of the tail cone behind the fiberglass top. Or two comm antennas under the rear seat. My aesthetic preference is for the two belly mounts. However, have those running with just belly mounted comm antennas had any problems with radio communication when talking to ground control, ATC or anyone else for that matter? In searching the archives I've found some discussion but not an answer to this question.

I'll try not to get too windy, but: Start with the transponder antenna location as it transmits at very high power and has the most restrictions. Minimum 3 physical feet from transponder Max of 8.8 feet of RG400 Minimum distance to COM antenna 30" Try to keep it somewhat away from the gear legs. Com antenna notes : Use RG-58 or RG-400 Bent whip on belly hidden by gear legs and set 3" inside gear legs = VSWR 2.6 (poor- reflection from transmitter is bouncing off gear legs and flows back into antenna and up into cable cancelling some of the transmitted wave energy) Bent whip on belly just aft of the baggage bulkhead = VSWR 1.8 (good) Straight antenna located between gear legs approx 8" inside = VSWR 1.6 (exceptional) (Doesn't look as pretty but increase in range very noticeable. Additional feature is ability to measure the height of grass.) It is much better to locate the primary radio antenna away from the gear legs even considering the longer cable. Backup radio will work fine with the whip antenna located near the gear legs. GPS antenna notes: Easiest to locate. The GA56 antenna can be located underneath the windscreen or somewhere on the top of the fuselage. (Not aware of ground plane requirements here but someone else may have more information). It is an active antenna meaning it has an amplifier that is driven from voltage traveling down the coax center wire. Note that if you intend to get your G430 or G530 upgraded to WAAS the GA56 must be replaced and the minimum cable length is 8 feet - so the best initial location is probably on the upper fuselage just behind the baggage bulkhead. Locate away from the COM antennas. Have fun, Bill DeRouchey WTD Aviation Technology N939SB, flying Tim Olson wrote: Not even the slightest problems with communications with the dual-belly antennas.

It gives me a real appreciation of those doing slow build. It is hard to believe the amount of work in the fuselage section until you see the amount of parts/pieces and rivets. The quality looks very good. It should save at least one to two years off the build time. Looking at it I got the same overwhelmed feeling the day the empennage kit and tools arrived. I guess the old saying of "How do you eat an elephant?" is true. One bite at a time. I have maybe two weeks left on the rest of the empennage, except for the attachment that I will do later. My 3 car garage is getting very small.
