Fishing reel releases tend to lock when under load. Some of them lock very effectively even under a light load.

They probably will still be shiftable, but it's never going to be as easy as when they're unloaded.

Re: Quick release

I would use a small pneumatic actuator that came in the kit. We used this on a prototype to hot swap the trailer and it worked great even under tension.

Re: Quick release

Could you PM me or provide me with more information as to how this winch system worked? We are very interested in this type of design. Thanks!

Re: Quick release

We are thinking of using a winch as well. We are thinking of having a winch to pull some cable back, which loads tension on some surgical tubing. Once tensioned, we plan on releasing a "clutch" that will disengage the winch and release the tension in the surgical tubing, thus kicking the ball.
