I've been trying to make a flying wing (in FAR), and want to use airbrakes to keep it as close to the pure flying wing design as possible (asymmetric thrust control would be ideal, but I digress). The problem is that the airbrakes in stock KSP open and close far too slowly for effective maneuvering. Are there any mods that add airbrakes which open/close quickly, or that speed up the vanilla airbrakes?

Reminds me a bit of the F7U Cutlass. I've tried numerous times to get something that can go fast, but the best I've gotten is a measly 380 m/s! I'd blame it on FAR, but I'm pretty sure that the problem lies with me.

Is something like this what you are thinking of? (Apologies for using MS Paint)
