I like 'em "BIG"!
Yup...exactly correct. Snug fit, purchased from TDRC. I also am now using them on everything. Oh how things have changed.They do not lock into place but they are a snug fit and you need not worry about them coming undone. Those look like they came from taildragger. If you see me avatar, I was using the green ones from dreamworks (same multiplex type plug) and they were still plugged in and working even though the plane was in pieces.
I also have the ones from taildragger in my slick that has 3 ail servos and they make putting together the plane at the field such a breeze. I have a few more sets from taildragger at the house waiting to go into my PAU edge. I also use the green version in my ef extra...pretty much every plane I have with multiple servo wings have them and I love em.
