Didiwatt, I had also purchased those HV69 (8) specifically for this jet....when I found out they didn’t fit, and because, I really didn't want to destroyed these beautiful servo mount
on most jet I normally have to redo all the mounts.....These were well done.
I just when through my drawer found a micro Ditex it fit perfectly so it on the rudder....and 3 HV93 that also fit nicely so I got another HV93 for ailerons and elevator’s....used the HV69 for Steering and Flaps....sold 2 to a close friend....and will used the rest eventually (3) for doors or something....
