I was thinking that some of you would sure be able to clarify me something that I was told by an RV 6 builder that I met. I asked him suggestions about building an RV 4, which is what I am aiming to do as soon as possible. (Well, I am still at the decision phase about what kit to purchase). He was busy, during a home-builder meeting which I was attending as a tourist or little more, so he explained me the thing rather quickly and I am not sure I understood it well. Basically, when he heard me talking about an RV 4 (which I love and had enjoyed a chance to fly), he suggested me to prefer an RV 8, instead, because of the different kind of rivets Van's adopted on it. He said that the RV 8 type of riveting is completely different and makes the structure stronger, expecially in aerobatics. Is anybody of you able to explain me the differences among the two, and confirm me this thesis? Thank you very much.

This saves a great deal of time for the builder. I built a RV-6A in which all parts measured and marked by the builder (Me!) before riveting. I am building a RV-8 which is pre-drilled for the most part. The time saved is astonishing. The newer designs from Van's Aircraft are for computer-aided cutting, shaping and drilling machines - the RV-7, RV-7A and RV-9 and RV-9A designs have even more of the parts pre-drilled than the RV-8.

As far as I know, the 8 is only stronger by design not rivets. Matter of fact the factory to me you could take out 1/3rd of the rivets in an RV-8 and it would still meet the structural requirements of +6 -4 g's At 04:06 PM 10/15/2004 +0200, you wrote: >--> RV8-List message posted by: "Alfredo Santoro" > >Hello, everybody. >I was thinking that some of you would sure be able to clarify me something >that I was told by an RV 6 builder that I met. >I asked him suggestions about building an RV 4, which is what I am aiming >to do as soon as possible.

If this is only news to me, my apologies. Problem: The canopy frame is made from round tubing. I hate round tubing! Where do you drill? Well.... Canopy Skirt: Take a flat strip of thin aluminum that has been laying around awhile. Next, lay it across the canopy frame to simulate the skirt so that it touches as many spots as possible on the fuselage side, frame ribs, etc Now the trick...Press down and move the aluminum strip around in a circular motion maintaining that position. The corrosion on the aluminum rubs off onto the frame tubing. Now stand back and you will see a perfect line on the tubing indicating the exact location where the canopy skirt will touch the canopy frame tubing. Canopy itself: This is different as the angle the canopy sits on the frame is different from the skirt. The way you handle this is to put the canopy in (final) position. Now with two pieces of aluminum, one stationary to protect the canopy and the moveable piece between it and the frame; move the aluminum around to mark exactly where the canopy will touch the canopy frame tubing. The back end of the canopy gets a little tougher...need someone inside, but it beats guessing! I am hoping that the more accurate placement of the holes will help prevent cracking and give a more precise rivet line. Time will tell.

You will see a faint contact line form where the canopy rests on the tubing. Just drill centered on this line and perpendicular to the canopy. Works on the windscreen as well as the canopy.

It really made the contact line stand out. - Larry Bowen Larry@BowenAero.com http://BowenAero.com > -----Original Message----- > From: Jim Daniels [mailto:jwdanie@comcast.net] > Sent: Friday, October 15, 2004 10:14 PM > To: rv8-list@matronics.com > Subject: Re: RV8-List: RV8 - Canopy Frame Hole location Tip > > --> RV8-List message posted by: Jim Daniels > > > Canopy itself: > > This is different as the angle the canopy sits on the frame is > > different from the skirt.
