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.
Is there not additional screws in the developer's kit for the 360 deg servos? Maybe packaged with the wheels themselves? Maybe they fell out somewhere?
Only other screw is a silver screw but it would have to self thread into the plastic of the servo. Seems like if you remove the wheel nonce or thrice the screw would no longer grab and the servo would become unless.
Maybe someone who also has the developer's kit can confirm which screw holds the servo wheels on?
Hi Lauren. One side of the wheel should be threaded and the other side is not like in the pictures below...
You will deffo need the screw to secure the wheel, as you correctly stated, it will fall off. As Richard mentioned, maybe the little black screw you need fell out while unpacking.
I just read your last post. Self threading a screw will not work as the shaft inside of the servo where the screw goes is metal. The screw in the photo below is what you need.
The 360 servo hub interior is not threaded like the HD servo and the hub of the wheel is too small a diameter for the black screw.
@Steve, I think the 360deg servos have plastic splines not metal... So perhaps the self threading screw is correct?
My hitec HS422s have plastic splines and the screw that holds the servo horns on are indeed self threading....
