Adam Wolley's video: Sealing the canopy frame with V-Seal

V–Seal is generally used on the inside of the vertical stabilizer to seal the rudder. This works well and is easy to install on both the right and left inside of the vertical stabilizer once the rudder is removed. With some trimming and great care, you can use V-Seal on the front and aft part of your canopy making your cockpit significantly quieter.

How to operate a TRT 800 menu upgraded from TRT 600

Operate the menu on TRT 800 upgraded from TRT 600

TRT 600 vs TRT 800

The challange is: the panel normaly is not changed, making labling confusing when reading the manual.

By disregarding the button marked VFR on an 800, the 600 panel has the "same" buttons. Then, using the labling from the TRT 800, one can read the manual for a TRT 800 and use the buttons on the TRT 600 panel.

With the same logic, the rotation button at the bottom right should have the same function on both. Note that the 800 has only one rotary switch.

The setup menu will apper when pressing ID (TRT 600: "FID") for 47 seconds. Watch the counter. For the different menus, see image below.

Use the MODE button to select sub menues.

If changing the NMEA, use the rotary button on lower right, then save and exit with MODE button.

Originally published Moutain High FAQ

Q: Is it true that medical and welder’s oxygen differs from aviation oxygen?

A: There are no different grades of oxygen being produced or contained in cylinders under DOT regulations.

Contrary to common myth ~ medical oxygen contained in a medical cylinder is no different than that contained in a cylinder marked aviators oxygen or otherwise.

Furthermore, because of the chemical nature of oxygen it must be as pure and dry from water as possible if stored under pressure. Oxygen is produced to be better than 99.9% pure, if not damage or contamination will result to equipment. Oxygen even holding the slightest amount of water moisture~ which is added during delivery for medical and industrial purposes may have helped to cause confusion in the industry.

As far as the FDA is concerned any oxygen cylinder marked as USP or medical is a drug, and has to be held~ dispensed~ and used under strict medical protocols outlined by the FDA and cannot be lawfully used for aviation purposes.

Oxygen cylinders labeled as AVO, which is aviator’s oxygen, or otherwise is not under the auspices of the FDA and are lawfully used for aviation purposes.
