Agibeaut.
I had the same problem. I ran into lots of these little clearance problems
in other places also.
I just ground a little notch in the top fuse skin to clear the horn. It
doesn't take much to allow the elevator to move a lot more. I also use this
as my positive down stop for the elevator.
Dan is correct, you won't even come close to using all the available down
elevator. Now you will use all of the up elevator on almost every landing.

I'd sure agree with Dan on this. The plane is so wonderfully pitch
sensitive that the stick hardly moves much, especially with the VG's
attatched.
Seems to me I opened a Pandora's box by monkeying with the bell crank and
for a while the elevator cable rubbed the inside of the stabilizer giving me
violent headaches and fits of frustrating madness! LOL There was a few
nasty words heard in my shop at the time......
I finally got it all worked out, but if you can, I'd try to do what Dan
said - nothing if possible!

I can't recall right now and the plane is at the airport, but I had trouble
here and checked and double checked the measurments. The bell crank was
hitting something or other, and seems to me I had to build a slightly
larger/longer/higher bell crank, but can't recall the details. I remember
being frustrated and thought I had screwed up, but all my measurments were
OK. That was long before I discoverd the group on Matronics! Wish I had
known about all you guys back then.....Found Matronics after it was
flying -dang it...

Once again, the Matronics List guys come through. I was about to do a bonehead
thing and start modifying the elevator horn, but you guys advised against it based
on experience. You are right.
I talked to Roger at ZAC and it is normal to have to trim the "L" angle at the
top rear Fuselage to allow enough movement to get the down angle correct. I'm
going to work to the minimum down angle also.
Thanks guys for your quick responses. I was in a really bad place there for a day
or two, and some of the same bad words that BokKat found in his shop turned
up in mine. They must come with the kit.

| Subject: | VHF & Transponder separation requirements on 701 |
Listees:
I am in the process of ordering my Garmin SL40 radio and GTX 330
Transponder and am unable to find minimum separation distances between
the two antennas. John at Stein Avionics seemed to think that 24"
would be sufficient. As I sit on my creeper in the hellhole I realize
that placing the antennas much more than arm's length away would not
be advisable. I also have to consider the location of the
Magnetometer for the Grand Rapids EFIS Sport.
I thought Bingelis would have the answer. If he did, I could not find
it. I also thought The AeroElectric Connection would have the
answer. Again, if it did; I could not find it. I remember reading
about radiating planes around antennas and needing them for maximum
communication distances but can't find the reference. I googled
Aircraft Antenna Locations and found "Mount the antennas at least 36
inches away from obstructions and as far as possible from other
antennas." It also said "On fabric covered aircraft...,it will be
necessary to provide a flat metallic surface or "ground plane"
extending at least 12 inches in all directions from the center of the
antenna."
Given the above background, I am considering mounting the VHF radio
antenna on the far starboard side of the tail section within arm's
reach of the Maintenance Access Opening (hellhole). I would mount the
transponder antenna on the other side, again right up next to the
vertical bulkhead. I would put the magnetometer between the two
antennas. The two antennas would be about 24" apart.
My question then is, from those who are flying their 701's: Is what I
suggest feasible, or; are you using a different plan that works?
All comments would be appreciated.

In general the comm. antenna goes on top and the transponder antenna goes on
the bottom (where the RADRA can "see" it and it can see the RADAR). On the
601 plenty of people have mounted the transponder antenna on the cabin floor
a bit behind the nose gear tube.

No idea what the minimum separation is.... BUT
The approach I took was VHF on the top and the transponder on the bottom.
Works on my Cessna, so I think it will work on the 701.
If you take that approach then you will have at least 36" of separation.

Stan.
I have mounted my com antenna on top at the front part of the baggage
area and the ELT antenna on top behind the baggage area and the
transponder on the bottom just behind the seat. I just had the
transponder checked and it tested just fine. The com radio works great
with the ELT antenna about 30 inches away.
