I don't use O rings for ministick motors, only for LPP motors, but I have not built any LPPs yet  Cheesy

Here is a picture of it in use...sorry I can't seem to make it upright.

Regards

I fly indoors currently and yes, the motors are wound outside the plane. The torque meter is to control the launch torque, etc.

I'm confused. I have never used a torque meter, forgive me please. 
Are you winding the motor and then installing it on the plane?
Do you have a picture of it being used? 

Sorry about not understanding.

No...the box is rigidly mounted....the loop where the rubber goes has arm soldered to it, this arm presses against the load cell to give readings on the LCD.

Here is the picture of the arm.

Its a Digital Torque Meter replacing the analogue version shown here.

I ripped a digital scale and mounted the sensor/battery in a box. Built the arm to press against the sensor to give the torque readings when winding rubber.

Don't be shy, how does it work?  Looks like a very simple and handy tool!  Would love to hear more about it, please.
