I was curious about the gap between upper fin root and the tail cone. I saw this cover picture on the November/December issue of Sport rocketry.
This is Jon Stenberg's Argo D4 Javelin model.
Enlarge the picture and you can see the the fin root gaps. So maybe I got it right this time.
With the HoJo fins and tail cone you could probably use them on this model.
Here's the model before decals.
It looks pretty good without them.
On this rocket you've got to do a little pre-planning before soaking the decals.
The top edge of a black band wrap is even with the end of the body tube.
Cut close to the black top edge. You can leave a little more clear border on the bottom.
The nose cone decal is set over the recessed line around the cone.
I'll cut this decal in two so there won't be a raised gap over the rut.
