Most Commonly Needed Spare Screws List:
Arrma 3S/4S Line:
Arrma 6S Line:
*Upper Shock Screws: 3x28MM Socket (when they bend just throw another one on, "tower saver screws")
*F/R Suspension Mount: 3x20MM Counter Sunk
*Wing Mount Screws: 3x20MM Button (If you don't have a flexible wing mount, grab a large bag of these )
*BulkHead Screws (bottom): 4x12MM Countersunk (will 4x14MM work here?)
*Motor Mount Slide Screws: 4x18MM Button (Better to go Socket Head w/washer here)
*Plastic side guard/Battery Tray Screws: 3x8MM Counter Sunk
*Plastic Chassis Braces: 4x18MM Countersunk (if you have metal braces best to go longer here, if the screw snaps you will have "bite" to remove the broken section)
Arrma 8S Line:
Bulkhead Screws (bottom): 5x16mm (IMO these are too short, I have used 5x18mm and they seem to work great, I think 5x20mm also works? (verification needed)).
Diff Cup Screws (Center, F/R): 3.5x16mm
Please post up what typically bends, breaks, falls off, or is just plain useful. I think this will be a great place to reference the sizes for the "good to have" spares.
Screw kits are a great place to start but also nice to have more of the common break sizes plus upgraded ones for the motor mount or longer screws where applicable. The kits as well, depending on the kit breaker are missing certain screws.
