Folks,

I have installed the Dynon EFIS, EMS, HS-34, and now AP-74 in my Velocity.  I have attached a picture of my panel.

I have been very happy with the EFIS and EMS products.  I have recently purchased the servos for both altitude hold, and autopilot.  I will begin installation of the servos shortly.

Has anyone else installed the servos in a canard aircraft?  I would interested to learn how the servo is being attached to the canard.

I look fwd to flying the autopilot cross country.  Tim

Let me know if you don't get any good info.  My plane is in storage now, so it will take a trip out to get pictures.  I currently have a TT ADI-2 installed and I upgraded from an old Navaid.  I plan to swap my HSI for a D10 in the near future.  The Navaid to TT servo's were a direct drop in, and my understanding is that the Dynon will drop in to replace the TT, so my installation should be close to what you need.  I like your panel.  I'm not going to cut mine so am considering the HS-34 and AP-76 on the tunnel ahead of the stick.  Not sure, but that seems to be unused real estate.  Let me know and I can make a trip to get some pictures for you if you can't find good info elsewhere.

Jeff,

Thanks for the response.  I am assuming you have a canard aircraft?  Tim

Installation Update:

Wiring - very straight fwd.  Although, I connected the disconnect switch on the control stick backwards.  We had fun trying to determine why the servos were not properly calibrating.  Finally we checked and rechecked the wires, and Dewey (my adult supervision) determined, flip the switch over - no problems after that.  

Menu setup – very easy to understand/calibrate (when wired correctly Smiley

Servo location(s) - we tested the servos about a hundred times before settling on a permanent location.  Dewey fabricated two separate brackets out of fiberglass.  The servos are secured to the bracket by four screws, two on each side.

Here is a picture of the roll bracket



 


Roll Servo - for a Velocity it is located behind the copilot's seat, in the passenger area. (many have been placed on the fire wall). Dewey did a lot of work to make sure that it is located in the area where it can be removed - if there is a future problem.  This proved to be a challenge.  The servo is placed fairly close the seat back.  It is too close to get a screw driver to remove the screws on the front side of the unit.  To solve this problem, Dewey floxed a piece of glass  (base plate) to the floor of the plane, with four bolts sticking out of the base plate.  The nuts can be removed, and thus allowing the servo to be removed/pulled out.  He also had to grind away an aluminum bracket (guide for the rear seat back cover) to make sure the control arm/bolt had sufficient clearance.  

Pitch servo – located on the fwd keel (between the pilot and co-pilot).  One again Dewey found the perfect spot for the bracket.  We test fitted a hundred times (drilled out four screw holes), and screwed the bracket and servo in place to make sure it truly was the optimal position.   It was then floxed in place.

Feel of servos on flight surfaces – I was curious about how much force would be applied on the controls.  When I purchased the plane in July, I did not have the roll trim hooked up.  I had about ten hours on it.  I then hooked up the roll trim, and it is a little too stiff for me. I will disconnect it.  It appears the roll/trim servos are not that stiff on the ground.  I am anxious to see how they feel in flight.

I will complete installation later in the week, and then fly!!  I will give my impressions after first couple of flights (and provide installation photos Smiley  Tim

Flying update:

Anyway installation is complete!!  I flew the Velocity with autopilot for about two hours today.  All I can say is AWESOME!!  Both roll and pitch were rock solid!  I am very happy.  I only tested the Nav and Alt hold mode (I do not test the heading/HSI, they will be next).

I even encountered some very bumpy air, and the Alt Hold worked exceptionally well.

Will report more.  Tim

That's great to hear. =)

What settings did you find worked well for you?  (Torque, Sensitivity etc?)

I did check the sensitivity - they (roll/pitch) are both set at 100%.

I flew for about three hours, and once again I was very happy with how solid the AP felt.  I did change from the NAV mode, and switched over to the heading mode.  Flew the plane with the HSI, and it responded well.  The plane did go into a 30 degree turn for the heading, it did initially loose altitude, and evetnually adjusted itself.

I pan to install my Garmin 496 on the panel (using the Gizmo/Approach Stack wiring System).  I will keep the group informed about this progress.

In summary - very happy.  I need to go on a long cross country to get the full affect - where should I go  Smiley
