Is this normal for a HED3 front not to spin for as long as my stock Ritchey front wheel? No I have not timed it but you can tell just by watching, the Ritchey seems to spin for ever. The Ritchey came stock on my Felt DA 700. Thanks, OH, the RENN disc seems to spin for a long time also.
It may not be a good thing that your HED3 does not spin as long as your Ritchey, but the spinning freewheel test has been disproven in terms of aerodynamics and raw speed. You may just have a slow wheel that spins for a long time.
This is a possible problem with any wheel that I have ever owned that used cartridge bearings. There is no maintenance free wheel. I was at a race this weekend where a guy had his new Zipp disk had exactly the same problem, the preload was way too high and the wheel did not spin.
