I have a missileworks RRC2L dual deploy altimeter and was wondering if anyone knows if there's a minimum altitude/speed for proper deployment to occur? Thanks.

Depends on the size/weight of the rocket. What are the specs of the bird?

Off hand minimum recommendation would be 500' not knowing any other details.

There are simply too many variables for a one size fits all answer. Packing tightness and method, pre-deployment descent rate, drogue or drougeless, chute type and size, and risk acceptance are just a few considerations. You’ll best get to know the optimum main deployment altitude based on observed performance. Personally, I never go below 400 feet to start, and adjust from there. This personal practice applies to both conventional main deployment as well as Jolly Logic Chute Release.
