Post heavy duty RC servos?
hello to all,
does anybody know some heavy duty RC servos (quite as strong as the nxt motors), for building a Lego tetrapod (3 servos at each leg, to move an over-all weight of approx. 3-4kg ) ?
conditions: Voltage 9V (7-12V) , and mechanically easily fixable to the Lego Technic bars...

Check out these guys, they have allot of heavy duty servos just for walking robots:

And for hooking the servos to the legos, its a real pain. Thankfully mindsensors are developing some servo to lego brackets:

Good luck, cant wait to see pictures of the robot :-)

Heavy Duty as in, metal gears, or brushless, or even steel gears?
