Re: Screw Terminals
Rick Hall
I have several of a similar design in my bucket. The terminals, not the completed fuse block. +300 hours, none have loosened up or failed. +5, +12, GND at my EMS module. 'quick' disconnects at the wing root for the NAV/Strobe cables. Pmag uses them too.

As to the fuse block design, it's quite elegant :) Unsure I'd want to push more than 10-15 maps total through it though. That said, you can get ATO fuses with a built in LED. A bit pricey at about $.60/fuse vs .12/unlit fuse, in bulk. The plain terminal blocks are available from various sources, most common in a through hole configuration. Digi-Key, Mouser, and Jameco all sell them. The ones I have are flush mount (free hanging?) so need some sort of a mount. VHB tape has worked for me. I have a few in the parts bin, can bring one to RR if interested. Rick

Re: COZY: Screw Terminals
I installed a VPX in my Varieze. It works pretty well. Depends on a third party efis however and you have to switch pages to get to the controls. I don’t have a zillion breakers on the panel and the wiring is a bit simpler.

There are alerts when something g pops and some additional circuit load data not available with a traditional system. Pricey though. If you have the money and are comfortable with EFIS displays it adds enough value its worth looking into. I put one in my Cozy 4. Izzy

Screw Terminals
Saro Marcarian
That's not a suggestion. It's not a special area in a far off airport. It's also not a semi vulgar expression. I'm curious about the use of Screw Terminals - the kind where the terminal block directly clamps your stripped and otherwise unterminated wire. I've come across an interesting solution to handle power distribution / fuse protection for the instrument panel which utilizes these terminals. Just wondering about folks' thoughts on this type of terminal in an aircraft environment. I have a simple audio mixing circuit (http://www.fdatasystems.com/ap-60-audio-mixer) that happens to use this type of terminal for audio signals and it fared well after a couple of hundred hours - albeit in a low current, signal capacity. The specific fuse / power block I was thinking of is https://czh-labs.com/czh-labs-din-rail-mount-ac-dc-532v-10-position-power-distribution-fuse-module-board-p0445-p0445.html. Has LED blown fuse indicators, handles 40 amps total, up to 10 amps per circuit. -Saro

Re: Auto pilots
Bruce Hughes
I need to clarify what I said before: 1. The Trio Avionics ProPilot is excellent as far as I know but I have been too busy to give it a fair trial. 2. The price is OK but I thought the hookup cable was a bit expensive so I complained to them. THEY MADE A SPECIAL CABLE just for me at a reduced cost. THAT WAS SERVICE ! 3. The special cable had 3 power lines (normal in all the cables), One ground (normal), 5 for each actuator (normal), and a pair for the twisted pair to the GPS (normal). 16 lines. 4. I screwed up (and they did too) because I don't have lines 14, 17, and 33 which are needed for the fuel sensor. So I cannot read the fuel flow until Olympia Avionics gets around to putting those 3 lines in. It has been 4 months, now. 5. The cable that I thought was so expensive has FOURTEEN MORE lines that I (and you) would not need. 6. YES, the two actuators are a bit hard to get in place due to their size. You will have a little trouble attaching the elevator actuator to the elevator tube. Each time you take the canard off, you will find it difficult due to the actuator. I was lucky as the company that I found locally (2 blocks from the airport and the owner is a pilot) charged me VERY little for their work. It is not a big job to make you own aluminum part if you are good with metal work. I few layers of bid can do the job but I think my part is the best possible. 7.Their CUSTOMER SERVICE IS THE BEST YOU WILL FIND ANYWHERE. Bruce Hughes

Release tape a 5 gallon bucket. Lay up 3-4 plies of BID approximately 1/3 way around the bucket. "Pop" off, trim sections out for your deflectors/ramps. Sand to fit cowls, flox in. Trim narrower to balance cooling. Rick

Axle grease? The standard is (I think) 3 coats of mold release wax (cheap) followed by 3 coats of PVA (less cheap). I have the best luck applying the PVA with a paint spray gun. I even wax duct tape when I use it, one quick coat.

Getting ready for RR, A glass question for CHT balancing. What's a good mold release?
Del Schier
Hi all,
You may have followed some of my recent posts about a Dynon EFIS and my autopilot; both to get ready for RR and another trip planned up North.
The EFIS D-10A is installed and working great with the new display thanks to someone here. I also got lots of help from the guys on my Navaid autopilot servo; especially from Chuck at Trio. The servo is working quieter and smoother but probably not the problem. I think the autopilot will work again with careful little setup and flight testing. It may have been me pushing the wrong buttons with inflight adjustments, we will see.
The last thing is to get my CHT’s balanced better. I put a deflector in the left side of the bottom cowl to balance 1 and 3 which worked great. Now my imbalance is between 2 and 4 with 2 running about 80 deg cooler than 4.
The last cowl deflector was made with pour foam, this time I would like to use aluminum flashing to make it a faster and easier project. What is a good household mold release?

Corection - Navaid Servo needed or help me fix mine.
Mike Tooze
Dell, I may have spoken too soon as re-reading your email I see that you are not flying in that you are not flying zigzagging like bouncing off the walls of an imaginary corridor. That is the symptom of the limit cycle I mentioned. It seems your problem is on the ground, testing the servo. I assume that you have gone through all the setup procedures, gain, damping, etc. It is a digital system driving the servo via PWM so a certain amount of movement/judder can be expected. If you have done the best you can with the adjustments then when you fly you should find that the air loads tend to reduce the vibration but will not eliminate it. It is a good thing that it tends to overcome any (small) friction and indicates that your a/p is alive. ;^) If I lightly hold my stick I can feel the vibration as the servo works - I believe this is quite normal. Coming back to my original point. Any backlash in the aileron channel will exacerbate the limit cycle effect. On a VE this can be virtually negligible. I don't know how it is with a Cozy with its different aileron arrangement. Apologies for any confusion. Best regards, Mike T ----- Forwarded message ----- From: Mike Tooze miketooze@...

Dell, What you describe is probably a 'limit cycle'. The output shaft on the Navaid is staked with a roll pin. This part of the train is after the servo pot/shaft which accurately positions the shaft but any slop in the roll-pin to shaft causes slight relative movement in the arm causing the servo to hunt between backlash positions. All you need do is to disassemble the output arm from the shaft by removing the roll pin and seal it back into position with, what I used, some flox so that there is zero play in the shaft to output arm. Mine needed this and still works well after xx yrs. Many of these units suffered the same prob. Few seem to do the ez thing and fix them. Nothing wrong with the Navaid single axis a/p!

Re: Was: Navaid Servo needed or help me fix mine. Now: more to the story.
Chuck Busch
Hi Del,
On the Navaid servo that gap is used to allow the solenoid plunger to lift before actuating the pivot arm. I’ve “tuned” a pile of these here at Trio and know that if you decrease that gap significantly the solenoid will not actuate properly. What I see in that picture looks about right based on my experience.
What exactly is not working correctly on that servo?
Best Regards,
Chuck

Hi all,
I got the servo out of the Hell hole and on the bench. The potentiometer is a very high quality one and it tests well for no dead spot near the middle, at least best I can tell with a digital VOM, wish I still had my analog one.
There is something fishy with the solenoid mechanism that meshes the gears when you engage the AP. I think a nut came loose but the position of the nut may be some kind of gear mesh adjustment. I am pretty sure Navaid is out of business and there is no way to ask them so I will ask the group.
In the attached picture you can see the locknut that attaches the solenoid armature to a pivoting bracket that pulls in the gears for the motor. It appears that maybe all I have to do is tighten the nut but what do you all think?

Re: Auto pilots

Hi Rich,
Actually with the Trio controlling the trim I have had the reverse problem. It had set the trim and when I turned off the autopilot I was way out of trim. It may have been the setup on the Trio but I am sure the trim direction was right. Either way you don’t want a surprise with trim settings.
