But think of it! Little mosquitoes marching into the cockpits with little bomber jackets on, stoically saying goodbye to their friends and loved ones as they launch off in their individual drones with insectoid pinups for nose art....
I'm of the opinion that the hypersensitive insect keys would be more effective than trying to do some sort of mind-machine interface at this point in time. It doesn't need to be particularly complex; if you have a 6 legged insect with wings that gives you eight inputs. Add in a mandible twitch to fire the weapon, and you've got the basic directions (up/down, left/right, forward/backward), the wings controlling pitch/yaw, and speed plus on/off. Maybe not as fancy as a human pilot might manage, but simple enough for our purposes. If we expect to go through a lot of these drones, we might even create a fabrication device to churn them out.
Actually, why not just make a fabrication device that uses nanites to replicate whatever parts are needed? That has to cut down on manufacturing time for custom parts ("I need 27 screws of this unique shape and size"), and with simple enough designs we might be able to just have them fed the raw materials and out pop a spare Armsdriver or the like.
Did we want to make a duplicate power cell for our armor that we could have charging/in stasis that we could swap out with our current armor battery? It seems like it would be faster and easier that way, plus if we use the same battery type for most of our Tinker equipment the modularity would become handy all on its own.
