Malcolm,
Thank's to remind about trim separate, on my MZ-24 it's also possible.
Would you please to give me a link for Ultra Precigion...?
Also I think about to change the door cilinders to electrics like this one http://www.lado-tech.net/en/e-doors/...door-30mm.html or to do mechanical with Futaba S3170G Digital Retract Servo w/Planetary Gear

(friend of mine did install on his CARF Hawk 1:3,75 scale, working perfect).

Kind regards,
Sergey
