Re: log grapple
What will you be putting the grapple on? Maybe a cable driven system like a clam bucket on a crane would work?

Re: log grapple
i made one just using a small srevo work ok but i need to do some reworking on it you should find one with metal gear's cus my plastic did not last long when i was towing the shop's push broom around. what are you looking for it to go on?
or this is a cale one i made has more power but should have made the grapple arms thicker and interlock to stop twisting.

Re: log grapple
You could try using a standard servo..Hitech makes a few very strong ones that you could try and hide in the grapple body and use mechanical linkage

Re: log grapple
servo would be easy and the size you want a standard servo would work

Re: log grapple
not sure how much torque you want but hobby city do some heavy servos at good prices http://www.hobbycity.com/hobbyking/s...&ParentCat=189 id avoid the bluebird servos though as ive burned a few of those out on my monster truck steering
