Help with choosing right servos for helmet

[Frid4y]

Hi guys i recently bought an ironman mark46 helmet, it suits my head perfectly and its made of resin. I want to make the faceplate motorized and i need some help with the servos, i need the smallest servos suitable for this purpose. Any help? Where do i start?

Ps:i dont want to modify/cut the external side of the helmet, i want to make the opening of the faceplate movie-accurate.

The best servo I've found for *most* helmets is the HS-125mg servo by Hitec. A little spendy but definitely a good servo. Otherwise if you want a much cheaper option, the HS-311 also by Hitec are good servos. Basically you have to find the perfect servo for that particular helmet because each helmet is different. Really it depends on how your hinge setup. If your looking for good servo setups, take a look here.

for the hinge Setup i have used this linear actuator is the best one.

Thanks guys, can i connect these servos to an arduino mini? I need small things cause my helmet doesnt have much space.

I read on servocity that the hs-311 doesnt have the "programmable" flag inside the table. It says "analog" . so it's programmable or not?

P.S.: my helmet is made of polyurethane resin and it needs a paint job, do you guys know the steps in order to get a good paint job? I already have car spray paint, i need to buy the primer. (But i heard that people are struggling with this resin so im a lil unsure about the steps)

Thanks!
