bearing size for hpi 14t vented clutchbell

[pjoseph]

I recently purchased the 14t vented clutch bell (link below) and wanted to confirm the bearing size for it.
I am using 5 X 10mm bearings but they seem slightly loose to me, and i do not have any 5 X 11mm around to try them out.

The HPI clutchbell (part #:77104) uses a 5x10x4mm ball bearing.

ok thanks, so i have the correct bearings but they just seem very loose fitting for some reason.
