hi guys,
first of all THANKS for the help.the pics is very interesting!
the plans shows a bellcrank made of plywood and a bolt or something. no bearings! thats why i started wondering. the futaba s5303 is a very large servo abd has two balbearings. do you think it is still needed a belcrank?any idea where to find ones with the bearings you mension?
one reason i am asking this is that i am thinking that a 223oz torque is very much for this plane. am i wrong???
85in j.bates SBD plane

also i am wonderind about ackerman . in many threads everyone says it is necesary. i canot understand why it is important to have slack in the non pulling cable.
thanks again
