Hello we just purchased the developer kit. We are trying to attach the wheels to the 360 degree servos. The black screws provided fit in the brass fittings of the HD servos but there are no screws that fit into the 360 servo. The inside of the 360 servo also is plastic and not threaded in the center.
The wheels do slide onto the hub of the 360 servo but I am sure they will not stay attached once powered.
Pictures of the wheels attached to robots on the website seem to show black screws in the center of the hub.
Thanks for the help.

Link to the servo wheel combination for sale. If you zoom in you can see what appears to be a black screw in the center of the hub. Maybe they changed the design?
Have you tried the rest of the black screws that came with the dev kit? The black screws can be a bit fiddly to start screwing in. Below are the bits needed for a continuous rotation servo and what came with my dev kit. Hope it helps.
@Richard.
I stand corrected. They are indeed plastic splines. Sorry, I confused myself for a minute.
@Steve may be right... I have only a Hitec 360/422 servo and a Hitec HS645 servo to compare... They do use 2 different screws to hold their horns on... The HS645 has a metal spline so the screws are threaded accordingly... the 360deg have a screw that is self threading as it has a plastic spline...
Yeah I remember this now when I was attaching a horn when I first got my dev kit. There does seem to be two size black screws. One for plastic and one for metal servo splines.
its a black screw whit ruf treath on
Here's the two different servo spline screws that come with the dev kit. The one marked in green is the one you need.
