Excellent, thanks both, that might be exciting Chris with no neutralising spring (?) Wasnt the Webra 'Pico' the same?
The little DigiSpark looks lost in there!
It is true, that the Webra Picco does not have a neutralizing spring.
But it is a lot easier to use than you might think. I did a lot of flying with my converted Picco Tx.
One advantage, you do not need a trim lever.
Fortunately the Command Master still has its return spring. (AKA heavy duty crossed hair pin!) It is a bit difficult to see in the photo. Very similar to setup to a Hobby People 1 plus 1 that I converted awhile back. The Command Master is pretty roomy! It was a fun build. Off to convert more radios!
