Bose Aviation Headset X Repair

I've had a couple of Bose Aviation X headsets for a number of years.  One headset had chunks of plastic broken out of both yokes (the parts that hold the earcups).  I believe I'm correct in that Bose…Continue

Bose Aviation Headset X Repair

I've had a couple of Bose Aviation X headsets for a number of years.  One headset had chunks of plastic broken out of both yokes (the parts that hold the earcups).  I believe I'm correct in that Bose no longer supports these headsets, and even if they did, they charge a flat fee for repairs that is/was very expensive!  The audio quality of the Bose headsets is unsurpassed, but it is inexcusable that they are so fragile for a $1000+ item!  To add insult to injury, Bose drops support on old…See More

Inexpensive Action Cam - Akaso EK7000

Recently, I designed and built a wing-tip tie-down mount for my GoPro Hero 5.  It works great, but I have to admit I really worry about having that expensive GoPro hanging out there!  Also, I thought I might like to make some videos with 2 cameras - one outside on the wing and one inside behind the pilot/passenger.  So, I did a bit of searching and decided to get an inexpensive camera for…See More

Oil Separator Catch Bottle

My 750 STOL has a Jabiru 3300 with a Motion Aero oil separator.  This has worked great and I have very scant drainage from the separator's vent tube, which terminates just below the lower firewall's edge.  It has totally eliminated any oily streaks on the aircraft's belly!I keep my 750 in an insulated hangar and use a thermostatically-controlled Hornet aircraft cowl heater (explosion-proof, solid state…See More

McFarlane "Vernier Assist" Throttle Control

I now have several hours on my McFarlane "Vernier Assist" throttle control.  I designed and fabricated a reversing bell crank which was necessary since I use a Sonex/AeroConversion "AeroInjector" throttle body carb on my Jab 3300.  The details of this installation are in a blog I posted here.  I really like this throttle control.  The ergonomics are great - when your hand is on the…See More

Throttle Reversing Bell Crank

Some time back, I replaced the Bing carb on my STOL 750/Jabiru 3300 with a Sonex/AeroConversion "AeroInjector" throttle body carb.  The AeroInjector's throttle body slide operates in reverse to most other carburetors in that the throttle cable pushes in to close the slide and reduce the rpm's to idle and the cable pulls the slide open for full throttle.  Typically, most builders use an AeroConversion throttle quadrant to reverse the cable direction.  By attaching the throttle cable below the…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

Hey John,  Thanks for the heads-up n the DAR question. I normally don't visit the 750 forums.  I'm happy to "act" as a DAR consultant whenever I can help.

Maybe there could be an "Inspector Consultant" forum.

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.
