This is a design by C. P. Mcgraw
Barclone page is here:
Lots of cool designs with Rocsim files for parts and templates.
This is my first Barclone build.
The Stryker came to my attention when I noticed the laser cut fin set available at erockets.
I was not familiar with a design called the Stryker so I emailed Randy Boadway to inquire.
Comes to find out that it's on the Barclone page at Ye Olde Rocket Shoppe.
Parts:

Laser cut fin set, nose cone, ST-10 tube, and EM 7-10 engine mount from erockets (ordered a long time ago, don't know if they're still available).
Other small parts coming from my stash (chute, launch lug, screw eye, shock cord, Kevlar leader, snap swivels, etc.)
Don't remember where I downloaded and printed the instructions from.
Maybe YORF.

They have some cool plans there. That one might look nice with a little cardstock canopy on the nose cone, like an interceptor.

Good idea. I dug this out of my parts stash:

Although it's for a BT-55 tube I think it can be sanded to contour an ST-10.

Assembled the engine mount.
0522202156[1].jpg


Copied the fin alignment guide (overhead type) to heavy cardstock and glued an expended engine casing to it.

A piece of scrap BT-50 tube will slip over this and telescope into the ST-10 main body tube for alignment purposes.

The two main wings are built from 3 parts, the main wing, forward strake, and rear strake.
Arranged the six pieces with the root chords abutting a straight edge on wax paper.

Glued the pieces together and covered with another sheet of wax paper.
This is weighted with a heavy object and allowed to dry overnight.

Calling it a night.

The wings came out straight and flat, no warpage.
0523200829[1].jpg


I cut the vacu-form canopy out and wrapped a piece of sandpaper around a scrap ST-10 tube.
Then contour sanded checking the fit frequently.
When the fit was good it was glued with thick CA to the nose cone.

Mounted the airframe to the alignment guide and lined up the launch lug line to the spot.
And started gluing the ventral fins

The two tail rudders (I trimmed the guide at this point because it was a bit unwieldy).
0523200855[1].jpg


And finally the two wings. They're heavy, so I used my 2 point spot CA tack method.

And from the side with nose cone on.

Almost there!
Need to let these dry before filleting.

Nice, I like the addition of a canopy.

Looks great! I agree with Beels; the canopy really make the whole thing pop.

What are you thinking for paint?

Maybe I should add orange pods on the wing tips?😄
For paint I was thinking red white and blue with contrasting colors on the leading edges of the wings and fins.
That's why I left the edges square. ;)
And thanks to GlenP for the canopy suggestion.
Assembly update later today.

Launch lug was glued on and everything got fillets.
0523201852[1].jpg


Recovery gear was assembled and dowels were glued on to the tail rudders.
0524201217[1].jpg


So assembly is complete.

Will be finishing this and a bunch of other builds in the next couple of weeks.
Finished pic will be posted then.
Laters.

very nice! you don't need tip pods, but could just paint the wing tips orange or just a stripe, maybe, if that fits in with your color scheme.

Actually I was thinking of gluing my left over Trajector orange plastic pods on the wings.

Just kidding!
I was being facetious when I mentioned pods.
