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

New Zenith Model?

I called Zenith the other day with a technical question and was having difficulty understanding Roger because of a whining noise in the background.  Finally, I asked him "what the heck is that noise?"  He said, "It's a Czech TJ-100."  "Why are you running a jet engine in the factory?", I asked.  Roger said, "I'm not supposed to talk about it, but we're strapping a pair on a 701 ... it's going to give near-VTOL performance!  We're looking at take-off rolls on the order of less than 10' and…See More

Tie-Down Ring Camera Mount

My kids gave me a GoPro Hero 5 Black for Christmas, and during an episode of "cabin fever," I decided to fabricate an external mount for my STOL 750.  I had seen a similar, commercially available mount with a cam lever bolt that allowed for quick installation on a tie-down ring without tools, so I decided to make my own version:I happened to have a piece of 3/16" 6061 that…See More

GoPro Settings and Playback on Windows 7 Computer?

The kids gave me a GoPro Hero 5 Black for Christmas.  I mounted it above and behind the seats in the STOL 750 and used a case that could accommodate a neutral density filter to cancel the rolling-shutter effect that makes the prop looks weird.I took some videos yesterday, and the playback is beautiful on the GoPro and on my Android phone using the GoPro app.  HOWEVER, apparently GoPro only supplies and supports software for playing their videos on Windows 10 computers and have taken down and…See More

VDO 360 001 Oil Pressure Sender

VDO 360 001 Oil Pressure Sender as used on Jabiru and many other engines.  0-80 psi resistive sender wtih M10x1 thread, which is interchangeable with 1/8 NPT threads.  This is a a genuine VDO sender, made in Germany, and in its sealed, original packaging.  I carried it in the plane for about 2 years as a back-up spare, but have now switched to a solid-state sender and no longer need…See More

Swift Solid-State Oil Pressure Sensor

It seems that the VDO resistor-type oil pressure sensors commonly installed on the Jab 3300 routinely wear out every couple of hundred hours - or less!  I'm at 550+ hrs and noticed my 3rd VDO sensor was starting to show signs of failing - usually evidenced by sudden spikes of high pressure.Some have tried to avoid this problem by either mounting the sensor on the lower oil gallery port (which gives lower oil pressure readings and has to be taken into account) or remotely mounting it via an oil…See More

Zenith "Donut" Nose Gear Suspension Installation and Testing

At Airventure, I expressed interest in the new Zenith "Donut" nose gear suspension system and Roger recently provided me with a kit to retrofit my STOL 750 so I could provide an early evaluation and testing (Zenith has been testing this in-house for a year).  This system will also be available for the Cruzer and the 601/650.  The 701 system will follow, but apparently it will need some modifications from this design.The original bungee system works well, but it does have a single-point failure…See More

STOL 750 - 500 hrs!

Posted on November 29, 2017 at 10:00pm 5 Comments

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…

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.

John:

There was a posting on the Cruzer forum about building the vertical stabilizer. I replied with the "draft" email that Roger had just sent me. It is not there now.

Did you delete it?
