RE: Pull-pull ailerons for biplane
I ordered some servos for this project today - the Bluebird BMS 380 MG for the ailerons and another for the elevator (which will also be pull-pull). I got a BMS 380 for the rudder (p-p) and a BMS 371 for the throttle. Haven't used micro servos before, having only built sport planes up to now. These little guys will definitely make the rather cramped interior of the Camel a bit easier to manage.
No problem making pulleys - but what about the pivot for each one? That will be a friction point to worry about as well. I suppose I could use a brass bushing with a screw or bolt going through for the axle. Ideas?
