MGL SP-6 Magnetometer

My whiskey compass has a very slow leak and needs new seals.  However, I "might" want to use that mounting hole for an AOA such as the AeroVonics (just bought by uAvionix!) AV-20s that is "probeless" and a simple installation, so I thought I'd go ahead and install a MGL SP-6 magnetometer connected via the CAN bus to my MGL XTreme mini-EFIS so I can remove the old compass and reserve that mounting hole for a future AOA or some other gadget.  I've already got the MGL RDAC-XF, SP-7 AHRS, and 2…See More

Forum Moderator's Note:I have initiated this topic as a central location for any plans or building details, errors, corrections or revisions that might be useful to other members - this is for all type-specific models of Zenith aircraft as the present forum format is inconsistent across the various type-specific forums and I can't "Feature" (similar to a "sticky") this topic in all of the forums. Therefore, it makes the most sense to centralize this topic in the Open Forum where it can be…See More

Those Darned Daubers!

Recently on a preflight of my 750, I found a mud dauber nest on my elevator cable. I tried to pull it off the cable and retrieve it, but all I succeeded in doing was breaking it off the cable to fall down into the fuselage!  I got a piece of stiff wire and a good light and peeked in the vertical gap between the rudder and the fuselage, thinking I could poke the wire into one of the nest's holes and lift it up and out of the top of the fuselage where the cutout provides clearance for the…See More

Cargo Tie-Down Rings

After reading Jim McGauhey's blog about his encounter with turbulence and canopy damage due to unsecured cargo, I have resolved to install tie-down rings in the baggage area of my STOL 750!  Although I don't have a canopy to potentially damage, I do have windows, a windscreen, and most importantly, my head!However,  when I looked for reasonably-small…See More

Banana Slot Block

My area of the country is plagued by mud wasps ("dirt daubers").  They love to build their mud nests in deep, dark recesses such as the multiple nooks and crannies found in airplanes!  I've had some success hanging "Rescue Trapstiks for Wasps" around the hangar, but invariably at annual I find at least one mud nest somewhere in the plane.  One favorite spot for them is in the top of the flaperon pushrod channel above the "banana slot," which provides wide-open access!  Lately, I've taken to…See More

Heatshield Products "Heatshield Armor" Exhaust Insulation

There is no doubt that reducing under-cowl temps provides many benefits - longer electronic component life, reduced chance of fuel vapor-lock, and reduced cooling requirements, to name a few.  Also, due to a carb mod I did, I had to install a small cabin heat muff on my exhaust pipe immediately as it exits the muffler, rather than being installed on the muffler itself.  My theory was that insulating the muffler (and the cabin heat muff) would retain the heat further down-stream and help produce…See More

STOL 750 Wing Attach Access Hole Covers

I have an Edition 1 with Edition 2 upgrades STOL 750.  In my part of the country (East Tennessee), we are plagued with "dirt daubers"/mud wasps when the weather turns warm.  The wasps are very benign as far as not aggressively stinging, but they love to build mud nests in nooks and crannies and an airplane certainly has  those!  Invariably at annual I find at least one mud nest somewhere in the plane - fortunately, they seem to avoid the cowl/engine area, but commonly I've found one in the wing…See More

STOL 750 - 500 hrs!

I accumulated this over 5 years and 4 months.  Annuals have been non-events for the airframe - finally had to install new brake pads during my recent annual and that's about it for parts over 5 years!  At about 100 hrs I did replace the 800 series tires with 600 series, but that was just personal preference.  They look like they'll be good for one more…

uAvionix skyBeacon ADSB-OUT Installation and Review

A while back I got hooked on watching The Walking Dead series - one of a number of shows and movies about a "Zombie Apocalypse" where most of the population is turned into zombies by a mutant virus, aliens, government weaponized virus, GMO's,  etc.,  - you get the picture - take your choice! The plot is predictable - a small band of "normal" humans makes a trek to find sanctuary from the hordes of zombies and…

Hello John,

First I want to thank you for all the good information you have shared with the forum.

I also have a question. Since the horizontal tail section produces a downward force in flight, I wondered if a larger horizontal tail section would cause additional drag. Have you noticed any reduction in speed due to your elevator extensions?

Hello, John

Looks like I can't reply directly to your comment re engine mount installation, so here it is:

I wasn't aware of the existence of this tool - it would probably have made life easier for the other three bolts, but I suspect it would not fit in the space I had for the 4th bolt.

Just inserting the regular C clamp took a great deal of maneuvering... 

But still, not as daunting a task as I expected. Patience and creativity go a long way.

Cheers

Carlos

John:

I hate to bother you again about this, but the "search" function in Ning is totally useless.

Briefly, I got a windshield which was flat across 80 percent of  the top, BUT the left and right ends were elevated about 3/4 of an inch. I got on the Cruzer forum and laid out my problem. Some of the members said that one could gently heat the ends with a heat gun to to make them flat. I tried this and could not evenly heat the whole end to lie flat, making these really ugly distorted ends that still had dips in them. I emailed,then spoke to Roger who said a small rise was not unusual. I can't figure this out because water will get under the rise. In the end, I reordered a complete windshield--which was expensive, but the shipping was almost as much as the windshield.

With that as background at an earlier time we discussed your installation and I bought enough butyl tape for the perimeter, BUT I cannot find the email or forum entry in which you set this out.

Would you please send this to me again.

Thanks, John for indulging my poor memory.

I got some 1/16 by 1/2 inch butyl tape ordered this morning. Amazon was nice enough to offer me 20 rolls for a total of $176. After a fair amount of surfing, I found a seller that would sell me one or two. Jon Croke had indicated that some of new bubble door builders had used adhesive on them. I ordered enough butyl tape to do the windshield and the doors--using the spacer bushings on both.

On the basis of your comments below, my guess is that the ideal spacer bushing will tubing will be the plastic fuel line that they use for model airplanes.

Thanks again. Ted Galdi

John:

Thank you VERY much for you reply concerning mounting the windshield. On the basis of a more recent post by you I had already increased the thickness of the windshield support to .050. I am going to order some 1/8 by 3/4 black butyl tape from amazon tomorrow.The idea of making a butyl "sandwich" sounds like an excellent way to seal the windshield.

What I did not see in your reply was a response to my suggestion that thin sections of 1/4 inch nylon tubing (like we have for brake lines) be put in the 1/4 inch openings in the windshield.

Did you leave them out?

Thanks again.

John,

I need to thank you for the tip about helicopter blade tape. I wandered over to the downtown airport last week and caught a mechanic working on a Jet Ranger (Sky4News) and asked him about it. He laughed a bit and told me to go over to Pep Boys and get a roll of clear rock guard tape, like is used on car rocker panels. Said it was the same thing, only cheaper. You might want to look at this.

John:

I still have not figured out a way to make my replies to your entries show up in them.

My current question is: How do you like your Conform Foam now that you have been flying the plane for a while?

Because of a motorcycle accident many years ago, I prefer a very firm foam on the seat base with no bolsters to keep the head of the femur off the seat. My experience with conforming foams is that they become soft and you sink in--which puts pressure on the hip.

BTW, the seats really do look nice.
