After carefully studying the pictures I trimmed the counterweight as shown on the plans (E-714 Trim Detail). The part remaining is 5/8th (like the picture shows). After reading it again I think I was supposed to do this when balancing it. Is it okay I did it now? Or will my weight be too light? If so, do I need to buy a new weight or can I do something to fix this? I don't think I will just be able to slide a new weight in there cause the skin that goes over it fits real tight and when it will be dimpled it might be really hard to slide this one out. Let me know.

The holes have to be larger because the wedge is thin, causing the countersinks to cut into each other from each side. The dimples/holes in the skins that go on top of this are the proper size and will clamp the wedge in place (the proseal helps with this). If you dimple the skin and countersink the wedge per the plans there is no way around this, so I didn't see it as a problem :) Kevin D.

I have been told > enlargement of the holes is indeed inevitable here. Another option is to flush rivet one side and leave the other side square-headed. It's less pretty, but it's going to be a lot stronger. If you're countersinking both sides of that wedge and finding that the countersinks are meeting each other, you'll have a knife-edge around the hole, which isn't condusive to long rivet life. On the Elevator, at least, you could put the square heads on the underside. -Rob ________________________________ Message 6 _____________________________________ Time: 05:35:42 AM PST US Subject: RV-List: Re: Tite Seal From: "Rick Galati" --> RV-List message posted by: "Rick Galati" rveighta(at)earthlink.net wrote: > I just completed the fuel tank SB on my left tank, using a gasket & tite seal. > That was a day and half ago and the stuff is still wet.

Lets all rack our brains and see if we can help make this race happen. I would think that lots of our suppliers could benefit from this kind of exposure! John Huft ********************************************************** Copied below is a slightly edited version of the latest information received direct from Race Director Eric Whyte (the excellent website is still saying the entry forms will be available before the new year 2006 - http://www.airventurecup.com ). Bob Axsom ******************************************************************* Hi Guys, Sorry it has taken so long to get back to you, I was in the USVI and the internet connection was really slow so it was kind of a read only situation for a week. Not a bad place to be stuck on a 6 day layover though! So here is the deal, we need to find our own sponsors. We need any and all leads you guys can come up with. The good news is that EAA is giving us our own separate checking account so all money we raise goes directly to the race. No ... Tax as in the past. Also if we should raise enough to have money left over at the end of the year all the better it goes into the kitty for the 2007 race. So once we raise money for the event it stays until we use it up or stop having the race. We are obviously looking for a large sponsor if there is interest but we are also looking for many small level sponsors. There are very few companies that are willing to spend $15,000 to sponsor an Air Race but we are hoping it would be easier to find ten companies that are willing to donate $1,000 to $5,000. The other part of the bad news is that EAA is charging us full face value for the wristbands so that is something we will need to look at. I dont necessarily agree with but that decision was made above my level as they say. The good news is we have one sponsor already on board that has committed to the lunch and breakfast in Dayton. Yes those are not the most critical of items we are looking for but they were offered and I am not going to look a gift horse in the mouth. ( The Sponsor is Commander Aero the FBO that hosts us) EAA is staying on to provide the insurance coverage and some publicity. We have control over the website and they have agreed to run a blurb about the website in Sport Aviation and also on the e-hotline. I have been really bogged down with work recently I was on the road 22 of 28 days in February, so I have not been able to get the race staff together yet. I dont see that changing anytime soon. I just got summoned for jury duty and crew scheduling blew a gasket and is frantically trying to get me out of it because apparently they cant live with out me for two days. It is nice to feel appreciated I think! In the e-mails you guys sent me several of you mentioned possible leads for sponsors, I speak for the entire race staff in saying we need all the help we can get. Since I am on the road nearly continuously at this point e-mail is the best way to contact me. I will keep you all posted.

Then it started back up again at 20 hours. I called Hartzell and they were awesome to work with. I flew to Piqua, OH had the prop fixed and also dynamically balanced on the plane. They fixed it all PDQ while I was using their courtesy car to tour the USAF museum in Dayton. They also gave me a tour of their factory. Overall, it was more like a mini vacation than a trip to a repair shop. I highly recommend them. BTW, their prices were VERY reasonable.... the repair was covered under warranty and the balancing, which made a VERY noticable difference, was something like $150 or so. Very cheap in my book. And all the work was done by THE experts.

If you don't put in the counterweights, or if the elevator is not balanced as per Van's instructions, it is quite possible that there will be destructive elevator/HS flutter at a speed lower than the recommended VNE. Flutter, if it occurs, could cause the HS and elevator to fail very quickly, causing a fatal accident. Put the counterweights in as per Van's design. This is not an area to experiment.

As I indicated in my previous post, I used it a few days ago on my left tank. Today I gassed up the left tank and checked my fuel gauge and the @#$% &*'d thing wasn't working. Checked the wiring, didn't find a problem, then drained the tank to remove the float/sender. To my surprise, after the last drop of gas had drained, Tite Seal began oozing out of the drain opening! So, I then removed the cover plate and using a mirror, saw there was an accumulation of tite seal in the bottom of the tank. Naturally, this has me concerned about the merits of tite seal versus proseal. Sure, Proseal makes it hard to get the cover off, but if you apply too much tite seal as I obviously did, it's a tad unsettling, since the stuff can run down the inside of the tank and possibly even get into the fuel line. I think I'm gonna clean this goo out of the tank as best I can then use proseal and pray for no more SB's. Some food for thought for those using tite seal.........

The F-4 had its engines 2 degrees down in the rear. Any extended engine runs or afterburner use on the ground melted any asphalt and was very hard on concrete behind the aircraft. A tailwheel jet will be very hard on any surface. There was no need for prop clearance either. I am sure there are "real" reasons but I don't know them. :-) Tom "GummiBear" Gummo Wild Weasel #1573 USAF, Major Retired http://mysite.verizon.net/t.gummo/index.html Apple Valley, CA Harmon Rocket-II N561FS - 270 hours - Still big smile do not archive ----- Original Message ----- From: "Ron Lee" Sent: Wednesday, March 22, 2006 5:56 PM Subject: Re: RV-List:keep the wieght off Nosewheel > --> RV-List message posted by: Ron Lee > > At 06:06 PM 3/22/2006, you wrote: >>--> RV-List message posted by: "D.Bristol" >> >>Long ago, my instructor explained that the nosewheel was there for only >>one purpose - to hold the nose up when the airplane was parked, and it >>should be landed accordingly.

But I do admit, the TD's sure look cute on the ground though! Flame Suit is on, ...I am good to go for the firework (...and for a lil'xcytmnt?)

I had a C-172 for about 6 years and she never saw it - 'cept in pictures. There is one feature that an airplane must have before she'll fly in it. Can you guess what it is? Two engines? A parachute? Nope. A restroom.

There used to be an RV around the area named "Divorce One" and I see a "Divorce Two" in the cards if he can't get his wife to change her views. Some of you guys must have had this problem--how did you deal with it? Did you get her to accept your flying & still have peace in the family? If so, how did you do it?

They needed something other than an airplane that melted & torn up taxi & runways. With the 8th airforce and the early 262's destroying runways, they picked the tail up & were able to off the ground to go after the B-17's and maybe have a place to land an hour later. I watch "Wings" on TV.
