Wow Great Photography!. You don’t have an extra dual 5755 servo bracket lying around-do you? ? Do you sell the elbow ball bearing? how about the whole assembly?
I have been using a 6vdc 3.5amp supply as the servos never get anywhere close to stall. Sorry, I am unable to sell parts I use for prototyping. Best to wait for a real kit of parts.
Any word Jim on when we will see this in kit form? I look forward to bringing one with me to Las Vegas in April! I’m sure it will turn some heads! Even better, seeing it run on the new software!
I’m also very interested on getting my hands on this type of arm, If you could or have already figure out the amount of oz it can pick up that would be great, id be thrilled if it could do 12 to 20oz at the end, a can of soda or a bottle of beer comes to mind and it would be a good match for my butler bot 
. Please give us a update on part arrival.
I don’t know if this arm will ever be a product because Hitec apparently can’t make the 5755 servo work without being jittery. That is the truth behind the matter, and there is nothing I can do about it.
Id hate to see that this type of design would not be produced because of servo worry’s there are plenty of other high torque metal geared servo’s out there. maybe the HS-5805MG Servo is not as jittery? As well as the dual 1/4 scale servo bracket itself would sell, also the arm design in principle is sound porting that over to the standard size should not be to difficult, The streamline look of these arms would put a fresh look on you existing line of arms. Don’t get me wrong they are nice arms I just need more options in the medium arm section, inducing the pivot you used in this design in 1/4 scale. Though I would love to have the high torque per dollar the 1/4 scale servos provide. don’t give up on the design new servo lines come and go…
P.S if anything I will take the jittery prototype off your hands

I’m sure you can make it work somehow Robot Dude!
This is an awesome arm!
