Another Terry Posted August 25, 2020 Share Posted August 25, 2020 Can anyone supply a wiring diagram so I can make up a Y lead for the Flaps on the Lil Cub. I have seached the www and can only buy ready made ones. Quote Link to comment Share on other sites More sharing options...
kc Posted August 27, 2020 Share Posted August 27, 2020 Welcome to the forum Terry. Nobody has answered yet which is unusal...... The answer is that you use Y leads which connect the servos in parallel. The horns for flaps are not the same as ailerons - ie not handed. Its just as cheap to buy ready made Y leads as to make yourself. About 5 pounds for 5 from Banggood including shipping or about 2 pounds each from The Component Shop Edited By kc on 27/08/2020 13:34:42 Edited By kc on 27/08/2020 13:42:22 Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted August 27, 2020 Share Posted August 27, 2020 Assuming you've installed the servos such that they need to rotate in the same direction it's just a simple parallel conection. If you need to reverse the direction of one of them then it would be possible to invert the pulses electronically but ready made units are very cheap. I would recommend installing the servos for the former condition... Edited By Martin Harris on 27/08/2020 13:40:58 Quote Link to comment Share on other sites More sharing options...
Geoff S Posted August 27, 2020 Share Posted August 27, 2020 There are two ways (3 if you you use a servo reverser as Peter did). 1: If you've installed the servos as per the drawing then you need to use separate receiver channels and reverse one of them. 2. You could turn one of the servos round so they are no longer mirror images (as the aileron servos are) and then a stndard Y lead will work (as will separate channels of course) 3. Apparently there are servo reverser modules but I've never needed to use one and prefer options 1 or 2. In that case the reverser is used to reverse the direction of one servo. Seems over complicated to me. The L'l Cub I intend to build will use number 2 which provides 2 options and doesn't have any disadvantages.
