==========================

Start:

On the video shown it is extremely important to note that this type of release has a pocket for the release pin end to be inserted after going through the first string to be released.

If the release pin end did not have a pocket to fit into, the release activation cord, with too much slack, could catch under the pin end making it impossible to release.

The pocket that the release pin tip fits into can not be absent.
If someone would use this video to pattern a home made release they must understand that much planning went into this release and the slightest deviations in a home made copy may result in a release failure.

Also not all that clearly depicted is the need for each string release to be of a smaller diameter cord as it progresses toward the release pin.
Using release strings of the same diameter cord will eventually result in a capture causing the release to fail.

To date there has not been made on planet Earth a hang gliding tow release that is one hundred percent infallible.

Dear Tad!

It will be fine to heard your opinion. It is very important for me because I am going to make web-store to supply such releases to USA as well and it will be needed to make all right. I will have more questions for you before I started it. And first of all: may be Russian Mouth Release (RMR) is not good for towing and nobody in US will bought it?

But... let's wait and see.

Feel free to use my posts and video. A bit later I will make one more and sent to you the link.

Cheers!
Aleksey

PS: I just finish reading of your post and have several correction:
1. Aleksey VIlkov
2. Alexander Kaluzhin
Ka - like a car
Lu - like a Lucas George
Zhin - like gin with tonic
3. Just for info))) Central Ural region, Yekaterinburg. The city found by Russian emperror Pert 1st and named as his wife Katrin.
https://en.wikipedia.org/wiki/Yekaterinburg

now seriuosly:
I can perform the loading test and suspend the 500 lbs to RMR and try to measure the force needed to hold the clothes -peg. May be it will clarify something.
BTW, I am connecting the RMR to one shoulder loop and bridle to enother one to reduce the load for RMR in two times. Innitially, it was common practice, the tow line was connecting directly to RMR and RMR bounded to harness via small Y bridle. I think it is not best way to set-up the towing system.

about the small spring inside RMR:
That spring is neede to provide tow-line disconnection with zero tow force, means without tencion. Everithing is possible during the towing... e.g. lock-out///save me God!!/// and it could happen that it will not be tension at tow line that why Kaluzhin add the spring to RMR.

about the friction into Bowden cable:
Yes, it is one of disadvantages of the system. Pilot should ceep RMR clean, without dust and periodically use grease to lubricate the hosing from inside. I am using several drops of this https://kennethtangnes.files.wordpress. ... wd-401.jpg

There are some backtalk, some in Tad's forum and some in Oz Report. See all. Discuss then in US Hawks. Start that has some links for tracing discusssions: http://www.kitestrings.org/topic7-720.html

[JoeF]

Calling all releases into the US Hawks forum! Links are invited. Study. Summaries. Etc.

Here will provide some food for thought: http://www.kitestrings.org/topic7.html
Has anyone yet made a comprehensive listing of all tow releases? Then controlled scientific studies?
