How to Improve a Swing Arm system
Posted: Mon Nov 12, 2012 1:31 am
I am rebuilding an Old Hickman EC-12 and as Sails Control I will use a Swing Arm System with a different approach.
I will use a Hitecc HS-5805MG servo, rated 343 oz. and speed .14 sec. and a Swing Arm not longer than 5 inches so I can secure the servo just on the lead.
Using Single Blocks w/Becket attached on the "Hull" and Double Blocks on the Swing Arm, I will be able to improve the Power of the servo to 1372 oz. at the same .14 sec. speed and have enough Main and Jib sheeting.
This can be accomplished because the mechanical advantage of the Pulley Physics that as described is equal 4 .
I Hope it will help somebody, the servo is very affordable and the all system is not complicated.
