Default EVR Hawker P1216 Plans

BT-20 Engine Tube, 2.75" long / 1 / BT-20J
CR-2055 Centering Rings / 2 / RA-2055
CR-520 Thrust Ring / 1 / EB-20A
Engine Hook, 2.75" long / 1 / EH-28
Kevlar Thread / 1 / SCK-24
Shock Cord / 1 / ECR-236

PART NOTES:
PNC-55IR Nose Cone can be obtained from the Estes kit #2183 Shuttle Express.
PNC-20Y cones can be obtained in Estes #303161 NC-20 Nose Cone 4 pack.
If using SEMROC balsa nose cone, make sure to add screw eye (not in parts list).

Parts view (JPEG should be 1/1 scale):


Front View (JPEG should be 1/1 scale):


Top/Bottom/Side Views (JPEG should be 1/2 scale):


ASSEMBLY NOTES:
Main Wings cut from 1/8" thick balsa sheet.
Tails and Fins cut from 3/32" thick balsa sheet.
Wingtip Rails cut from 1/4" x 3/16" balsa stock. May substitute dowel rod or launch lugs.
Be sure to swing test as some dimensions may end up slightly different. Additional nose weight may be needed for stability, especially if using balsa cones.

Enjoy (and if you build one, you MUST post pictures )!

Later,
EV

EV,

Noticed there is not a RockSim file for this one. Did you happen to work one up?

Thanks, Andrew!

I've made some adjustments to the file, based on the construction photos and EV's description of the build. The stability margin for this bird is about 2.13 on a B4-4, 2.15 on a B6-4, and 2.02 on a C6-5. This works out well given EV's description of the flight as being straighter than he anticipated.

EV, if you see anything in this file that doesn't match the prototype, shout!

Length: 19.77"
Diameter: 1.352" (BT-55)
Fin Span: 9.20"
Weight: 2.20 oz

Simulation runs shown below. All three listed engines work from a 36" x 1/8" rod.

Gee, thanks guys! I don't have RockSim, so I appreciate you pulling together these files.

Not to be nitpicky, but Craig, you did ask me to note anything that I see that's different from the real bird. I'm out of town for the week, so I'm working from memory here...

1 - Wingtip side missile rails are missing.
2 - Not sure if you noticed that main wings are 1/8" and the rest of the fins are 3/32" thick
3 - The rear horizontal stabilizers aren't that far aft. The rear tip of the fin is parallel with the end of the body tube, not the rear of the root edge. Overall is about 1/2" forward from where you have it now.
4 - Same thing on the lower vertical stabs. Extend the rear edge of the upper stab down to find the point. It's around 1/4" forward.
5 - I don't know the total mass, but I did happen to measure the PNC-55IR nose cone, and it's 15 grams. There's no additional clay weight inside.

Later,
EV

EV,

Thanks for the feedback. Andrew really did a bang-up job getting the RKT file worked up, so I more-or-less just used his file as a foundation. I'll tweak a new copy sometime tomorrow, after the Shuttle gets off, with these corrections.
