I have just fitted the rudder
s and controls last weekend. I have built
almost the complete model
but held off from fitting the deck until I had time to consider this problem. The best I could come up with was to reverse the control arms so that their screws fixing them to the rudder
s were accessible from the front after the deck had been fitted. Doing the linkages this way means that you have to bend the control arms to miss the strength rib in front of the rear skin and also you might have to reverse the servo
travel direction on the Tx. I had to do this.😉
I have included a picture to show what I have done. it does not solve all of the problems but makes adjustment possible.
I have also included a picture of the dual speed controller
. I know you have solved this problem but I have tested this unit and it works very well. I hope this helps in some way.
