I respectfully tender the following. I was talking with Dave Ronnenberg at Berkut last week on this very subject. He and most of the other fast glass kit guys recommend a fuel tank coating product by Jeffco. They are a San Diego area company. Jeffco has their data/spec sheets on the Internet. This stuff is impervious to most chemicals. Check it out it you want the simplest solution to sealing a glass tank. Look into this before you decide that glass tanks are such a big worry. Ronnenberg probably has built 50+ glass planes and rebuilt another 25+ bent birds. He works with the Rutan folks all the time, not to mention all of the black projects he consults on. If he said it is OK, I think you can take that to the bank. Dave commented that most glass tank leaks are builder caused and not normal if good construction practices are followed. These comments are not intended to start a firefight. I just would like folks to consider facts and not speculate. Are alum tanks better, sometimes, but there are plenty of kit metal bird builders who have their share of leaks. Welding is the best method to use if you elect to use alum (IMHO), but you still have plenty of issues of securing the tank and connection/movement challenges in composite, as well as in other types of aircraft constructions. There are a more than a few thousand glass tanks in service out there. Yes, you can find the leakers and they make great stories over a can of beer, but most of the time you will find bigger issues with homebuilts...like pilot caused accidents. I believe lack of currency in type would be a bigger issue to worry about if you have too much extra time on your hands and need to worry about something!

The plans (my set) says the design stress limit is +/-7g's at 800 pounds or 5600 hundred pounds. This would be for the standard design wing and not the extended wing that many builders are using. Divide your expected gross weight into 5600 and that would you the G rating for your airplane and you can decide if you are comfortable with that. Perhaps one of the engineers on the net could enlighten us on the design stress limit of most "spam cans" and the difference between design limit, ultimate limit, etc. Make sure to use a high enough gross weight number when you license your KR so that you won't be violating the FAR's every time you go flying by being over gross.

A little here and a little there and the elevator was about ready to glass. On Saturday= I only had about an hour to work so I traced the elevator on plastic and cu= t the fiberglass and pelply. On Sunday afternoon I went to the garage ready= to lay up some glass. I microed one side of the elevator and then started wetting out the glass. When I went to transfer the wet glass to the elevator, I discovered I had the wrong orentation. Not wanting to waste a= ll this glass I peeled the plastic off and smoothed out the glass and squeeg= eed it in and it looked good. Then I noticed that I had forgotten to flox the trailing edge so I pulled the fiberglass off, trashed it and squeegeed as much resin out of the foam as I could. I then took a long break to collec= t my thoughts and went out and glassed the other end of the elevator.

I have flown in a RV-4, but not as PIC. The RV-4 is a very fine plane and can handle a much more powerful engine than the KR. The KR is not made for aerobatics. The RV-4 is a much different plane than the KR-2. One of the things I liked about the RV-4 is that it seems to have more room because it is tandem seating. You are not sitting shoulder-to-shoulder with your passenger and each of you have room to move around and fly the plane. And it flys like a P-51. GREAT RIDE! If you can find a ride in a KR and a ride in a RV-4, you may find it easier to make your decision. Either one will be a great project and a LOT of fun.

However, I don't recall any one post pulling these together as a single issue. There is no single correct answer for any one KR as most builders build to fit themselves, as it should be, and is one of the nice things about the KR. Here is my opinion on the matter for those that care to read on. Start with the seat. Select the seatback angle and seat height that gives you your desired visibility over the panel. This will be different from builder to builder. Generally you'd want to keep it as low as possible so the canopy can be as low as possible for less drag. After the seat height is established, have someone use a level on top of your head while you are seated in the KR and measure the height from the top of the seat back to the bottom of the level. Add whatever distance you want for head room and this is the measurement you want to build your canopy to. By using this process you won't end up with an airplane that "won't fit" because someone said to put the seat X inches off the floor and/or just building the canopy to the height the material comes in. This is the route I took and you can see from the pictures on Mark Jones' web site that I got a pretty good fit on both. I'm sure my KR will be a bit slower because of the taller canopy but at least I'll be comfortable for the ride.

It is an equivalent of total drag of the plane including parasite, induced and slipstream drag. Airplane designers use it to select powerplants, get the best performance of the airplane (Lift/Drag issue) prop designers use it to balance out thrust and drag at the highest speed.

I'm in San Antonio and Oscar Zuniga just moved back here from Oregon. There are two KR builders here who are not on the net (they're in my EAA chapter) and I know of one KR in Austin and a new KR owner in Houston who is on the net but (I think) out of town on business at the moment. I'm sure some of them may contact you soon. I know Katy is a little ways from San Antonio, but it is real good to have you on the net. Bob Stone is up near Killeen, a good ways from you, but he's on the net and has a couple of KRs under his belt and he's full of good advice. There's also some guys up in the NE corner of the state between Dallas and Arkansas, but they are almost as slow builders as I am. I'm not sure, but I think at least one of them probably has a still hidden in his shop somewhere. They're a lot of fun to hang out with, but I'd be careful about any advice they give you. Again, welcome, and I know you will have a lot of fun both on the net and with your KR. By-the-way, if there's any way you can get up to the Gathering, it is THE best way to meet a lot of these guys and a lot more who are NOT on the 'net, not to mention seeing a lot of KRs and a lot of great talk about building and flying them.

I didn't mean to scare you guys. I think if there's a fiberglass tank that doesn't leak, it might be mine, but I'm prepared for the fact that I could be wrong about that. I laid up all of the internal surfaces on a sheet of glass to make absolutely sure that I didn't have any pinholes (see http://home.hiwaay.net/~langford/wingtank.html ), and used lots of flox and layers of tape and resin in the corners. One of the things that worries me about mine is that it's rigidly mounted to the main spar and might be subject to external twisting forces which might crack it. I think vinylester is not as brittle as some resins though. Maybe what I should have said is that there's something to be said for building the tank completely BEFORE installing it, then test it and make sure it doesn't leak before installation, whether composite OR aluminum. You have to admit that composite tanks are more prone to degradation over the years due to different fuel additives. The key to building one that doesn't leak is to use vinylester resin (AS&S sells it) and lots of excess resin. I'm not a big believer in sloshing compounds though. I've heard too many tales of clogged filters to go that route, especially with the auto fuel manufacturers putting whatever they feel like in their brews these days. For 100LL guys that might be alright, but 100LL isn't going to be around forever...

Our tank is glass and I certainly hope that is true. I know that Jerry was very particular about the way he built it. The tank in the Little Beast is aluminum because at that time I did not trust myself to build it out of glass. Daniel R.

It is tough using someone else's stuff when you are not really sure what is in it. It might be good to discuss it with the builder to see what kind of material he used. Do you think that if you build the tank on the other side, that you can build it the same weight as the existing one? I would not worry too much about glass, it they are built right. Daniel R.

Rule of thumb is 1G less for every 100 lb (45 kg) over gross. So if RR = states 7G at 900 lb gross then at the Australian limit, max. loading = becomes 5G.

YEEE HAAAWWW !!!! Sorry....I just had to get that out... I shall remember this day for the rest of my life !! This evening, 5/4/02, at 7:40pm, I took off for my first flight in NX770CG. YEEEE HAAAWWW !! Doug Bryant did the first three flights, in recent weeks, and we worked a few bugs out. Doug reported that quite a bit of aft pressure on the stick was required for level flight. We tweaked the leading edge of the horizontal stab down, with the flying wires, and he said this progressively helped, but it still needed a little more. He also said the airspeed and altimeter seemed to be sluggish in reaction. I'll drill the static holes out to #40 before the next flight. The engine also wanted to stop running when at idle, on short final...gotta work on that. The time between opportunities to fly seems to be long. This evening, brought near perfect weather conditions, and it was MY turn. Sam had the Stearman out, and Joe was in his J3 Cub. These two planes are of the pride and joy of Benton Airpark (beside Doug's and my Pietenpol's). I did a thorough pre-flight, and went out and did some taxi's up and down the turf runway, at Benton. I got the tail up a few times, and it all felt good. The sock at the North end lay limp, but the one at the South end showed a little bit of a left crosswind. As I rounded the North end and set up on runway heading, I once again asked for the Lord's blessing, and added full power. With some forward stick, the tail came up within several seconds, and I still wasn't quite sure if this was going to be my take-off roll. Pull power, or leave it in...decision time...then the noise of the ground went away, and the earth began to get further away. OK...leave it in. Out of ground effect, I glanced the A.S.I. and it indicated 40 m.p.h. Nose down a little...keep airspeed. Climb at 45 or 50...WE'RE FLYING !!!!!! YEEEE HAAAAAWWWW !! I gotta go by feel...the airspeed, and altimeter is still sluggish in reaction. The green Kansas countryside is just simply AWESOME, from an open cockpit airplane !! Nothing like I've ever experienced. This sky is HUGE !! Look left, look right, I didn't even notice the radiator in front of me. Glance the instruments...180 engine temp, 10 p.s.i., ASI 45 m.p.h. ..lookin' good. 400 AGL, bank right ...crosswind...oops... not enough rudder to keep the ball in the middle...lead turns with rudder. Stay in the pattern. We did about 10 or 12 laps around the race course, at almost pattern altitude. Check pitch control, roll control, yaw control... get a feel for it. She really tells me what's going on. Very sensitive on the controls. I like it. Bernard Harold Pietenpol is a genius in design. He got it right. OK, the sun is about halfway below the horizon, and it's time to land. The good Lord kept me safe so far, and now it's time to land. If you weren't there to see the landing, then it was a perfect landing !! In actuallity, we did 3 landings. I kept the speed up a little, and was probably a little low on short final, but we landed without any incident. YEEEE HAAAAWWWW !!! I'm going to make this 40 minute log book entry in RED !! Joe had to leave, but his wife and a couple of friends, and all the kids are running around down at his hanger, and I had to give them a YEEE HAAWW and have a couple of beers !! A day for the history books !! I hope to fly off the hours, and make it to Broadhead to meet all you guys !!
