Last comfortable launch of this year...
 
A few of us got together at the local LPR/TARC field - report here:

Rocketeer's Corner - A warm December launch...

Surprised the SkyDart II flew well on a B6-4.
The original calls for a B6-2 or B4-2

Great launch report! This post made my Monday morning. Nice pics! Wish I could have been there. Keep-em' rocking.

I was a bit surprised too, as the few gliders I have call for short delays too, but it makes sense when conditions are right. A less than perfect boost angle or some wind would still probably call for the shorter delay with the II. As a standard rocket example, I use a D12-5 on windless days for my demo flights with the 2.6" Goblin, but it needs a D12-3 if there's a breeze that noses it into the wind during coast. Both motors put ejection right at apogee, with the 5 seemingly hovering before ejection in no wind. Also, I wouldn't be surprised if the B6-4's average 3.68 second delay is a little shorter than it was back in the days of the original Skydart. Bill may be good at building light too. :)

Bill's builds look like catalog display models at close range (closer than 6 feet).

That's not the lightest way to build. ;)

The Skydart belonged to my friend Allen - mine would have fallen like a brick :)
