I live on a grass field in Oklahoma, and at one time we had three RV's on the field plus several factory planes. So after much research and time making promises to my wife, I decided to build an RV 7A. I've got the tail done and the wing almost there (after a three month absence working honey do list). I also have the fuselage kit on the shelf ready to start this fall. So my big question is what if I wanted to change to a "7" tail dragger... what would it take? Just looking at the two aircraft on Van's web site it looks like the change is in the fuselage kit, so I would have to send my engine mount and landing gear back and get the tail wheel, is this correct. I'm sure I'm not the first to change their mind. One might wonder what drive me to a big change in plans. Believe it or not it was safety. Grass fields and tail wheels go together, plus don't forget the sexy look of a day gone by. Can anyone tell me if they've ever done the conversion at this point of the game? Thanks, Dan S.

It says "enlarge this hole for flap rod access" (or something like that), but does not call out a dimension. I assume it's pretty small considering how close it sits to rivets on either side, but I'm curious what size hole is called for here. 2) The other is the static port. The location is clearly shown on DWG 28, but not he size of the hole for the port. Anyone? And thank you Bob St. Paul, Minn. ________________________________ Message 3 _____________________________________ Time: 07:13:08 AM PST US From: Dwight Frye Subject: Re: RV7-List: Change of Heart 7A to 7 ??? --> RV7-List message posted by: Dwight Frye Dan, Absolutely. I made my switch from a 7A to 7 prior to ordering the fuselage kit ... so for me it was a non-issue. However, the factory RV-7, which had been finished and flying for a while, got converted to an RV-7A (the opposite direction to what you are proposing, of course, but it shows how alike the two models are parts-wise). It took a little work, but they were able to even make that switch in fairly short order. Since it sounds like you have not started on the fuselage, you are right that it is just a matter of switching a few parts. I'd suggest calling Van's bright and early on Monday and talking to them about exactly what is entailed .... but your assessment of mount/gear as being the big issues is pretty much on the money. -- Dwight do not archive On Sun Jul 17 09:14:20 2005, Daniel Storer wrote : > >--> RV7-List message posted by: "Daniel Storer" > > >Big question, but first the short story.

It has to accommodate the size of the rod end bearing. I waited until I mated the wings and had the flaps on and then gradually enlarged the hole until there was no interference with the pushrod. Then I traced the hole onto a piece of paper and transferred it to the other side. I had a couple of pictures of other people's planes that I used as a starting point. The hole is kind of an inverted V on the side of the fuselage and kind of a slot on the bottom. The hole actually took out 2 rivets on the bottom. Probably the best thing to do is wait until next week and trace someone else's holes at Oshkosh and use that as a template for yours. As far as the static port hole goes, I believe this is just a #30 hole for the rivet. I'm not positive about this but if you track down the static port rivet itself you should be able to tell for sure.

In taking off the left and right skins, I realized today that there are 4 vertical rivets -- apparently #40s -- just forward (maybe 4-5 inches) of the big center section bulkhead. They were not drilled and nothing in the process up to this point apparently called for them to be fitted to anything. But DWG 28 says these are dimpled rivets and if I'm going to dimple these four, I need to do it now. I checked the various drawings and could not find the use for these four rivets.

If so, don't dimple these yet as you will use them to match drill the vent angle. You can dimple later with a pop rivet dimpler.

Careful when you first run the flaps down the first time or you may bend the flap pushrods if the fuse holes are too small........don't ask how I know. Start the holes small and run the pushrods a little at a time so you can watch the action and enlarge holes where needed. I have over 60 hours with Van's static kit & have had no problems.

Difficulty level would depend on how far the fuse has been completed. If you have not started the fuse, it would just be a matter of exchanging parts and carrying on.

The DRDT-2 (www.experimentalaero.com) will be on display at the EAA sheet metal workshop and or the Avery Tool booth at Oshkosh. I will be at AirVenture from Monday through Saturday. Stop by and give the DRDT-2 a test drive. For those of you who already own one, I'd enjoy meeting you so stop by and say hi. Paul Merems ExperimentalAero
