Have you room to attach the push rod to the opposite side of the servo arm?

Forgot to say that whatever method you choose, it’s always good practice to check everything works as it should on before you launch. I’ve seen some nasty accidents when this isn’t done.

Please forgive me if this sounds critical or personal. Getting the basic instalation right is central to model boating. Making or modifying a pushrod is normal stuff, I made one the other night, took me 10 mins.
Maybe I’m getting old and a misery, but electronic ‘cures’ for an instalation problem seems odd.

Turning the servo round 180 degrees won't alter the direction of rotation of the disc on top.
An electronic speed controller may put out less power in one direction than it does the other. In that case you would need another reversing lead if you didn't want to use the reversing switch on the Tx.
My solution would be to make out a 'settings' card for each model e.g.
Name of Model:
Control (e.g. rudder)
Reverse switch setting i.e. N or R
Just refer to it before operating the model and, as Charles says, make sure you check the directions before launching the model.

It's cheaper than buying reversing leads.

I've no idea whether or not all servos run the same way; I can't see why they should, but there's no reason why not either. With servo-reverse switches installed on all new sets it shouldn't be necessary to tamper with the servos.

Before we had such a luxury we used to reverse the rotation by swapping over the two motor wires and also swapping over the wires at each end of the feedback pot track. These days with SMT electronics it's impossible – 'cos there ain't no wires no more!
