    --> RV-List message posted by: "Jim Nolan" <jamespnolan@earthlink.net> I've got to order the wing and fuselage for my RV-7 project and I need to know if Van's has redesigned or fixed the problem with the Tip-UP canopy's leaking water when it rained. I'd like to have a Tip-Up but if they still require taping the front seam to keep rain out of the radios, I'll go with a slider. Jim Nolan N444JN

These were installed by the builder about 2/02 and still starts fine at temps in 30's. I think the suggestion to try another starter is a good move. We are probably going to SYI Sat. Come join us.

    Subject: Re: Cylinder Blocker
    --> RV-List message posted by: "Pat Hatch" <pat_hatch@msn.com> Hey Len, This seems to be a pattern in the RV's where the #3 cylinder runs much hotter than #1 and somewhat hotter than 2 & 4. The blocker baffle in front of cylinder #1 seems to even everything up. You have just so much cooling air and I think the idea is to distribute it in the most efficient way--keep CHT's even and in the 350 degree range in cruise and below 400 in the climb. Beyond that, I think exit air area is the key, so if CHT's are still too high, I would begin trimming some of the lower cowl ramp area to increase exit air. Also, I believe you will get some success with smoothing out the exit air flow by adding a rolling-pin shaped baffle on the lower firewall area as many have done.

Not always so simple - I had about 400+ landings on my Van's cheapies with no vibration/shimmy problems. I replaced them with Michelin tires (on the mains), and have consistently had a fore-aft shimmy at 22 knots ever since. It is a compromise between reduced air pressure, which helps the problem, vs difficulty pushing the plane back into the hangar. I don't sense that they are out of balance, because in that case, I would expect a little vibration just after liftoff, which I don't have. Every vibration is a spring, mass and damper. Change any one, and the vibration behavior changes. The Michelin tires are noticably heavier than the Van's ones were.

    Subject: Navaid pushrod safety
    --> RV-List message posted by: Fiveonepw@aol.com Howdy -list! Just installed my Navaid servo in the right wingtip similar to Bob Butler's installation outlined on Sam Buchannan's website: http://home.hiwaay.net/~sbuc/journal/navaid.html and after eyeballin' them itty-bitty #6 screws on the rod ends, I'm a tad nervous about what would happen if one of them were to let go- If either end of the tube comes loose, you could be in for an interesting ride, to say the least. Has anyone come up with a way to keep the pushrod from interfering with the aileron linkage if it comes loose at that end, or with the servo or wingrib if it gets disconnected at the other end? A couple of ideas include "hanging" each end of the tube with some light extension springs to hold it up and away from stuff if it does come adrift? Or maybe an upsize on the rod ends to #8 + safety wires? Yeah, so I'm paranoid- anyone else? From The PossumWorks in TN Mark Phillips -6A 51PW & still grinnin'!

    --> RV-List message posted by: "Doug Rozendaal" <dougr@petroblend.com> Maybe not paranoid, That is exactly what we do in the Mustang on the gear retraction pushrods, they have a pushrod with a rodend bearing that pushes the gear up. If that rodend fails, which has happened, the pushrod can jamb preventing the gear from freefalling to the down/locked position. To preclude that we have a small spring on the pushrod that will pull the pushrod up and away, allowing the gear to freefall. FWIW.

Grinnin' like a 'possum, eh?! Yep, those screws do look very, very small. However, unless something totally unanticipated or atypical happens, they are never under much load. When the servo is powered down, the clutch has no drag. When the servo is running, it is moving the ailerons a tiny amount. Biggest load I can think of is if when we overpower the clutch by moving the stick when the servo is energized. But even then the properly adjusted clutch breaks loose with minimal effort. Your idea about springs that would pull the pushrod up out of the way in case a screw broke may have merit if you *really* want to eliminate all possibility of jammed controls; the tricky part will be setting the springs to be strong enough to raise the pushrod without adding loads to the servo during normal ops. However,if a screw broke, more than likely the pushrod would be under so much tension it would jam in spite of the very light springs you are proposing. As far as I know, broken pushrod screws have not been a problem with the Navaid installation. Sam Buchanan

    --> RV-List message posted by: "Ken Brooks" <kenbrooks@charter.net> I'm trying to seal up a 1 3/16" hole that has a 1/4" cable going through the center and am having trouble locating the right size rubber grommet (Wicks, ACS, etc.). Seems like the ones that fit the large bulkhead hole size all have larger holes for the cable also (1/2"). Has anyone had any luck making their own rubber grommets by cutting/punching out the right cable size hole in the middle? Any suggestions would be appreciated. I'm trying to seal well and look good too. Ken Brooks Roscoe, IL RV-8 spaghetti everywhere

    --> RV-List message posted by: "JOHN STARN" <jhstarn@verizon.net> Not that this happened to us ....BUT.......as Tom says "Put the landing light in that bay" and start using a smaller bucking bar for those tight places. We started with the large "hammer" looking type bar but was given a much smaller one. Approx 2 X 2 and 1 1/2" thick with holes drilled in for the differant size rivets and four poliched sides. It was made from a larger bar and is small emough to fit between the cleco ends and a lot easier to handle at arm lenght and out of sight. OK....OK.... "we" (read "me") dropped the larger bar three times and were able to install the landing lights and eliminate two of the three dings.

I am getting "failed to deliver" bounces on e mails that have my address as the orignator but which I have never sent. So having Norton's or other antivirus protection (which I have and are great) or even a hardware firewall (as I have) won't protect you from someone "Hijacking" your e mail address. Your "Hijacked" e mail address is then used to send a virus to someone who may not even be on your address list. In fact your computer is not involved in this operation at all. Just the use of your e mail address. I have recieved bounced messages indicating that I had sent a message to someone who was not even in my address book. Apparently there is a portion fo the message you can right mouse click on for "properties" and perhaps discouver who the real send of the message is, but that's where it just starts to get too hard for me. Like what do you do with that information? My IPS provider adamantly tells us not to respond to a "remove me from your list" link as all that does is confirm they have a valid e mail address - so what to do?? So if you get a virus from you good old buddy, just realize it it likely not from him at all. Fortunately, Matt's protective measures keep that type of stuff off of these lists, but these bad guys can "harvest" e mails addresses in many ways and from many sources. Hope they find a fix soon.

I think Mark is more concerned about the little bolts actually breaking from extreme overload. I am almost certain I have nyloc nuts on the bolts in my plane. This is another example of where the bolts should be pulled down tight so there is no rotation of the bolt itself or the ball part of the bearing. All rotation should be the rod end around the ball bearing.

    Subject: Navaid Servo Installation
    --> RV-List message posted by: Hopperdhh@aol.com Hello Fellow Listers, While we're on the subject of Autopilot Servos: I think that my installation came out great. I don't have a website or any pictures of it, but while I was building the right wing I fitted the servo into the bellcrank bay. My pushrod is only about 4.125 inches long. I installed aluminum doublers and nutplates on the forward side of the spar web. The doublers are to keep me from worrying about the web cracking. There is room to get to the servo to adjust it fairly easily, and it can be removed using an allen wrench. I had to cut off two of the mounting ears and mount a plate across the bottom of the servo to get it as far as possible from the bellcrank. A longer piece of aluminum tubing was found and threaded for the 6-32 rod ends. The linkage angles were calculated to give equal left and right travel of the pushrod to the control sticks for equal servo travels from center. I only had to drill a single hole through the lower side of the bellcrank to put a 5-40 screw for the pushrod pivot. Maybe when I get time I can get some pictures. Regards, Dan Hopper RV-7A (almost done)

    Subject: Starter
    --> RV-List message posted by: Wheeler North <wnorth@sdccd.cc.ca.us> Jason, Although this is not universal, high current Voltage drop problems that change with temperature are often due to carbon in a poor connection. The connection changes as the temp changes. First thing would be to check the contactors and the various connections. Have a helper and do voltage drop checks at every connection and contactor. A V-drop check is done best with a DVOM in V mode and just leap frog the leads from point to point starting at Bat + and ending at bat -, cranking at each check with the mags disabled/plug leads disconnected, but leave the plugs in for cranking load. (be careful here, but if you have some good quality long test leads its very doable, and the best way to diagnose the problem) Anything other than the starter having more than .1 V-drop is a problem although some cables are long enough and small enough to get up to .5V drop. My bat/mastersol/startersol/starter/eng gnd/bat gnd loop is 00 cable and is less than 4ft total loop length. This weighs less than 2 lbs The trick to using large cable is to keep it short. If there is not significant V-drop, and the battery is good, then your starter is the culprit, probably carbon in the commutator and or weak brushes. W Time: 08:07:55 AM PST US From: Jason Sneed <n242ds@cox.net> Subject: RV-List: starter problem? --> RV-List message posted by: Jason Sneed <n242ds@cox.net> I need some help to diagnose a problem I am having. When my airplane was built the builder did not think the battery had enough power for the airplane because it did not spin the prop very fast for startup although it usually would spin it enough for startup. The builder installed a motorcycle battery in the luggage compartment for extra power. During the winter I had a time or two when the the starter or battery just barley turned the prop and I had to jump the plane in one occasion. I noticed the battery in the plane was old and I thought a new one would fix the issue. I order a new odyssey battery and that seemed to fix the problem. After about 30 hours of flying with the new battery I decided to remove the 10 pound motorcycle battery from the luggage compartment thinking I did not need it anymore. I flew another 5 hours (warm weather 70's) with no problem. two nights ago the low was 40 degrees down here in NW florida, yesterday it was about 55 when I went flying, sure enough the starter/battery just barley turned the prop enough for the engine to start. nothing drains the battery when the master is off (no clock ect...) and the voltage on the battery is 12.8-12.9. With the alt on it shows about 14.4 volts. Does anyone have any idea what my problem is? I only have trouble on the first start of the day (my guess is that once the oil heats up it is MUCH easier to start the engine.) Could I have a weak/bad starter (it is a lightweight starter)? any ideas or things to check would be great. Thanks, Jason Sneed Commercial Lending Officer First National Bank and Trust

Kent Paser's book "Speed with Economy went into this in depth. I would advise caution in closing up the barrel porting of the baffle too much since this area is not normally instrumented and I would have no idea what the minimum dimension would be before high barrel temps might become a problem.
