Spoiler arm auto-deployment
Hi gents!
I've been playing around with my LEGO Mindstorm-set (don't act like you don't envy me!). I've been thinking about the spoiler arm deployment / retraction. On the 737, the spoilers are automatically deployed upon ground contact or in the event of a RTO. Should a go-around be initiated after landing and the spoilers are up, they will automatically be retracted. This is something I want to add to my TQ.
So here's the idea:

In short, this solution will automatically raise the spoiler arm from the down detent, and then depoy the spoilers. The secret is a bell-cranck, which is a L-shaped contrapment that transfers horizontal movement into vertical movement (other uses are possible too).
The important thing to achieve here, is that there should be a bit of "play" in the linkage from the servo / motor to the spoiler arm to remove the load of movement.
Any comments, suggestions and improvements are VERY welcome! :)
