Scratch - SR-71 Blackbird (Scratch)


Contributed by Scott Turnbull

Revell SR-71 Blackbird PMC


This describes a semi-successful plastic model conversion of a small Revell SR-71 Blackbird kit. A 13mm motor mount was added to the kit.


This was undertaken as part of the EMRR 2006 Rocketry Challenge. It represents my first attempt at PMC.

I chose the kit for its classic styling, potential for stable rocket powered flight, and apparent ease of conversion. Various flying rocket versions of this plane have been available over the years. A ready to fly starter set is currently on store shelves. The challenge of rolling my own, albeit a smaller version, drew me to this one.

Upon opening the kit I found it to be a very simple build, consisting mostly of an upper an lower fuselage/wing combination. A narrow channel ran from nose to tail along the central body, narrowing at each end.

Revell SR-71 Blackbird PMC While an 18mm would offer more thrust to power a heavy kit, the restrictions of the airframe barely lent itself to a 13mm mount. I determined that a Gnome body tube was a nearly custom fit for the main body channel. Even that small tube didn't fit inside the kit as shipped.

I used a heat gun to soften the airframe and press it around a length of copper pipe. This stretched the central core of the ship until the Gnome tube could be sandwiched between the two halves. I also heated and deformed the Gnome nose cone to fit it into the nose of the SR-71.

Once the rough heat molding of the airframe was done, I used a razor saw to slice the SR-71 nose off. This would be glued around the Gnome nose cone to provide a press fit into the Gnome tube inside the rear airframe.

I used Gorilla Glue to bond the Gnome tube to the upper airframe. I used Testors liquid model cement to glue the airframe together around the body tube. Once the airframe was assembled, some additional spot heating with the heat gun was used to fine tune the fit.

Revell SR-71 Blackbird PMC An elastic shock cord was fitted to the Gnome tube prior to sealing it within the SR-71. To help increase stability, I packed the nose cone with BBs and plastic model cement.

The final assembly consisted of using Testors liquid plastic cement to glue on the tail fins and engine details. A second launch lug from a Gnome kit was separated from it's ring and glued to the bottom of the SR-71 near its center of gravity.

Odd'l Rockets: An Odd'l Parachute Endorsement!
A post from TRF: From Jerry - "I love using my well used/broken in 18" JonRocket parachute. There are no more memory fold lines. It's very soft and fluffy. Even the shroud lines are super soft from all the talc and not hard and whiskery. I have had dozens of flights with this chute and it just gets better like a well worn hat or shoes." Hi Jerry, That's good to hear! I designed those parachutes for JonRocket and BMS. They are also used in RSR amd Odd'l Rockets kits. My goal was to produce the best LPR parachute out there. The chute material is 1.5 mil thick, a bit thicker than most kit ...

Model Rocket Building: Estes Lynx, Kit #7233, Build Part 1, Parts
This is one of the two newer "T" engine builder's kits, The Lynx. The Lynx is brother to the other new mini engine kit, The Scorpion. I picked the Lynx over the Scorpion simply because I liked the design better. All the parts are of high quality. One of the BT-5 Intake Tubes was a little out of round. Not a problem, you only use half the tube on the cut intake. These are the small cooling vanes that go around the outside rear of the engine mount tube. These are tiny! I'll have to fill and prime them before gluing on the tube. Sure you don't have to do this, but filling ...

Model Rocket Building: Lonnie's Shroud Line Hook
Did you ever have trouble getting shroud lines through the tight loop on a snap swivel? Lonnie Buchanon showed me a tool he made at the last R.O.C.K. launch. TIP: The end of a stiff wire is bent in a tight, long "U" shape. Hook the "U" around the shroud line loop, feed and pull it through the swivel end. Simple and effective.

Model Rocket Building: MRN Idea Box TIP- From February 1969
Mojo 1986 was selling some older Estes Model Rocket News (MRNs) on Ebay. For me, one of the most valuable pages was "The Idea Box". I did some screen grabs and will feature some older ideas that still have some value today. "This safety cap by Hervert H. Maston of Lavonia, Georgia works well as a wind direction indicator in addition to its primary function. The tube may be a plastic straw or an LL-2D launching lug. The flag may be of red plastic tape or of painted PRM-1." How many eyes were poked by people leaning over the launch rods? Launchers are typically low to the ground and I'm ...
