RE: 8611's in Comp-arf 2.3, won't fit elev.
interesting....didn't think of this until I saw your post....I bought the 8611"s based on a reccommendation of a friend, for my 2.3......
I didn't think they would fit but can, but not exactly.........
The overall center distance between the mounting holes is larger because the servo is larger.....
the 8411 measures .75 X 1.34 X 1.36
the 8611 measures .82 X 1.58 X 1.56
I opened up the mount on the width, and there wasn't too much needed on the length. It gets close to the skin, but there is more than the thickness than a typical cap strip with the epoxy glue so I don't think it really matters
I do need to add holes for the servo leads to come back.
FYI the servo mounts for the wings have the same center distance problem, and so do the "plastic" mounts from horizon hobbies.....They all can work, just a minor adjustment for have the laterst and greatest
