Flexing servo tray

[secrtwpn1]

I noted in my 2.5" Subdriver that my servo tray is flexing when the servos for the rudder and diving planes are operating. It appears I need to put in some type of support. Any suggestions???????

Thx

Farlan,

First thing I suggest doing is to figure out why the tray is flexing. Is it because the servo is pushing against some resistance? (e.g.: rudder or dive plane at it's maximum deflection) Or does the tray flex even with the smallest amount of servo movement? Also, do you see the flexing if the servo is disconnected from the pushrod?

If you do need a support, you should be able to add a brace at the end of the servo tray that sits on the lower, inside of the dive module tube.

i will check the resistance when I get home. Thx! Never that about that!

Make sure the linkage is not binding going thru the seal at the back bulkhead. It needs a very straight shot going thru there and the servo arm changes the angle of the rod some as it rotates.

As they said above, check the binding. Servos are torquey little buggers, and they can overcome a lot of resistance without you knowing it. The linkages should travel through the entire distance of travel with no binding for proper operation.
