OS K1 Escapement Instructions?

Post by iflylilplanes » 27 Mar 2019, 08:43

Hi All, I have aquired an OS K1 escapement in a model built and flown back in the 1960's from a flying mate

I would like to get a scan of the instructions that came with the K1 to keep with the K1 in my collection.

Can anyone help with a scan please?
Cheers,

Dave

Here ya go Dave. The K-1 is the compound escapement.

Great escapements, the push, pull output looked like you could afford motorised actuators. Weird thing was that OS recommended press and hold should give LEFT rudder. I always reversed horn location to give RIGHT like standard Elmic operation. Also from memory you could compound them together to give up and down elevator plus a spare function such as flaps with another esc...Just like the Bonner compound set up gave. Great in theory but very difficult to operate reliably.

Used one in my scaled up KK Cub years ago on one of the prototype s/c encoders.

Thank Shaun,
I have counting the K1 5 different OS escapements now, and, would like to have a couple up as a working demo set like you have in your videos, with this instruction sheet I now know how to wire them together.
Cheers,

Dave

Thanks Wayne,
I found the same pdf online about 11:30 last night, thanks anyway. I have a large collection of escapements now, Wright, OS, Elmic, Bonner and Babcock, all but the Wright's are usable and working. I may even use one in a model just to see how it was to fly with a rubber powered servo.
Cheers,

Dave
