Thanks to all for your comments, they have been very helpful.
I am very gradually getting to know how to drive the gigacontrol software.
One question, is it possible via the software to set up the neutrals independently on 2 mixed servos, such as the 2 elevators and if so how do I do it?
Using the tx, it is possible to adjust the neutral position of the 2 servos together, but this means they have to be mechanically set to identical positions and this can be difficult.

Comments please

Regards have a good weekend
