I'm sure Van's can send you a list of what you'll need to send back.
The parts will need to be like new and they may not credit you 100% for
all the returned parts (their site says they have a 10% restocking
fee). Since the cost of the -7 fuse and finish kits are cheaper than
the corresponding -7A kits, I would suspect you'll still get a bit of a
refund even with the return penalty.
On the technical side, if you've done no work on the fuselage, there
should be no problem whatsoever changing over to the taildragger.

Hey Dan,
It is certainly doable...I have a friend building a 7a form a 7...I.e
going the other way to you.
Now I wonder if I could set you guys and maybe you could help each other
out to swap the parts if you have all your on hand?
Let me know if your interested.

Subject: RV7-List: Change of Heart 7A to 7 ???
--> RV7-List message posted by: "Daniel Storer" <dstorer@OKWiFi.com>
Big question, but first the short story. 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.

Dan,
The quick answer to your question is yes, it has been done, but in
reverse. The current factory model RV7/7A was originally built as a
tail dragger, and then converted over to the 7A which it is today. I am
sure it is just a matter of swapping some of your parts such as the
engine mount and landing gear legs. The brake line bracket for the
firewall is different and I am sure there are a few other parts.

Conversion from a *completed* -7A to -7...
Starting with the rear half...
Remove the rudder and elevators. Probably want to get the aft elevator
pushrod out to make room.
Drill the tiedown bracket off the rear bulkhead, no big deal. Cut the
"mouse hole" in the bottom of the tailcone skin for the tailwheel spring
mount.
But can you even get a tailwheel spring mount in there between F-711 and
F-712 once the aft deck is installed? Will it fit into the inspection hole?
And then can you phenagle it to get it oriented?
Probably doable, but I'm guessing it's tough at best. Good friggin' luck
getting back there to rivet that stuff in. I actually think you'd be better
off drilling out the aft rivets on the side skins, or at leastt one side,
and peeling that side skin back (forward) to gain access to the bay between
F-711 and F-712, and a little access forward of F-711 for
bucking/shooting/squeezing. I personally wouldn't want my tailwheel spring
installed with pop rivets, but that's just me.
Careful on the alignment when re-riveting that side skin and the tailcone
together. Take care not to introduce twist.
Install the tailwheel spring and tailwheel. Install chains or a rocket
steering link or what have you. Rig that up.
Moving forward...
Remove the steps, then you gotta patch those holes. Or just keep 'em on,
but you don't need 'em on the taildragger. If you do remove 'em, will you
have to drill out the baggage floor skins? Don't think so, since I believe
the steps just slide out and aren't fastened inboard, but I'm not positive.
Double check that.
Move to the front half...
Rip out all the brake lines. Most likely rip out your fuel supply tubing as
well (easy to redo once the weldments are gone).
Pull the engine. (yes, pull the engine)
Hoist the plane.
Remove the nose gear. Remove the engine mount. Replace it with a
taildragger engine mount...you will need to cut clearance notches into the
bottom corners of the firewall flange for the new location of the mains.
Remove the main gear legs. Install them in the new engine mount. Jeez, can
you even do that? I understand the mains are match-drilled to the engine
mount. You may need to get new gear legs that are match drilled for your
new engine mount. Figure that out.
Plane is now on gear again.
Remove the weldments from in front of F-704. Fill all the holes with
shorter bolts.
Now you've got exterior holes to patch:
- step holes
- old main gear holes in the fuselage
- lower cowl old nosegear "slot"
Cut new holes in the lower cowl, aft lower corners, for the new mains.
Install new brake lines through the firewall. Don't forget the
reinforcement "patch" on the firewall where the fittings pass through.
Possibly install new main gear leg fairings. New upper gear leg
intersection fairings.
Redo your weight and balance. Do the requisite flight testing.
....
I personally wouldn't want to go through all of this. Just build a
taildragger from the get-go if that's what you want!

Note that in the original question he said he "had the fuselage kit on
the shelf ready to start this fall". So, fortunately, the original guy
asking the question will _not_ have to go through the lengths suggested
by Dan here. :) Thank goodness, for him!

You might find someone in the area that is going to build a -7A and is
just about ready to order the fuse kit. Have them buy the -7 kit and
trade parts. Otherwise I think it's basically sending back your main
gear weldments, the engine mount, the rear tie down, and the nose gear
stuff. Then you'll get the tailwheel weldment, the tail wheel spring,
wheel, etc., the other engine mount, the little fuse gussets and
probably some hardware.
The only thing that I can think of that might bite you would be the
holes in the VS rear spar. On the -7 your not supposed to drill them
until you mount the VS to the fuse but I don't know about those "other"
planes. :-) I think the NG guys have four AN3 bolts and we TD guys have
three AN4 bolts. They probably don't interfere since the conversion has
been done on other aircraft. If you haven't drilled the holes in the VS
then it doesn't matter.
Since you haven't built the fuse then this is just a parts exchange.
Other than the VS attach holes there are no differences between the -7
and -7A on the tail or wings.
Godspeed,
