Estes Shark #1111, Build, Part 4, D.I.Y. Nose Block (Coupler)
Blog
The coupler was cut to 1 1/4" long. The original kit nose block was 1" long. I feel better having a longer, more stable sliding joint. I decided to make the coupler bulkhead wall out of 3/32" basswood. The BT-50 coupler was set down onto the basswood and the interior diameter traced with a sharp pencil. Two circles were cut out. The sides were sanded to a circle. Both were glued cross grained. A ... [More]

Estes Shark #1111, Build, Part 3, Engine Mount
Blog
The 20/50 rings were notched for the engine hook and Kevlar line. The lower ring is on the left. I highlighted the notch with pencil. The upper ring is on the right. Note the Kevlar notch directly opposite the engine hook notch. The instructions would have you position the upper ring above the top bend of the engine hook. I position the upper ring lower, over the top of the hook end making ... [More]

Estes Shark #1111, Build, Part 1, Background
Blog
In the early 1970s, Damon bought out Vashon (Freon propelled "cold power" rockets) and production moved to Estes in Penrose, CO. CLICK HERE Initially, the Vashon line remained unchanged. In 1973, Estes started producing their own branded Freon propelled kits, the "Cold power Convertible" line. CLICK HERE All six designs were BT-50 based. The initial kits included RP-100 ... [More]

Some Estes Kit Font Names?
Blog
I was fortunate to work in a print shop as a graphic artist doing paste-up. I also spent too many hours setting headlines on a VGC Photo Typositor. When redrawing some kit decals I've had to search online for fonts. A few specific fonts show up again and again in many Estes kits. I can assume that Estes had a limited number of fonts and reused them many times. My hometown printshop had 35 ... [More]

Estes Time Warp Build, #7321, Finished
Blog
The model is taller than you would expect. The upper payload section could be used for an altimeter. I used some masking tape on the nose cone shoulder for a tight friction fit. The yellow adapter was glued into the white BT-50 using Fabri-tac. If you are trying to match the face card paint, the fin mask is difficult. Overall, the finished look is very good. [More]

Estes Time Warp Build, #7321, Part 16, Lower Decals
Blog
These two wiring and instrument decals go between two fins. There is no third decal on the launch lug side. The "shield" decals go on each fin. There are six CAUTION decals, each going on the rear of the BT-5 motor tubes. The engine mount was finally glued in using epoxy. The slower dry gave me some time time to insure movement and alignment. The marked masking tape was my depth and fin ... [More]

Estes Time Warp Build, #7321, Part 15, Upper Decals
Blog
The roll pattern decal is shown positioned all the way against the top of the BT-55 tube. This could lead to upper edge peeling. I'd recommend leaving a little of the clear above the upper edge. Position the top of the decal a bit below the top of the BT-55 tube. The roll pattern has four black vertical boxes. How can you center four boxes over three fins? Well, you really don't. Center ...

Estes Time Warp Build, #7321, Part 14, Fin Mask Fix?
Blog
The black fin was masked off by rolling a strip of tape over the rounded leading edge. I attempt to "blend" in more sprayed yellow paint. Notice the tape around the brushed and sanded white undercoat is "floating", not stuck to the surface. This makes a smoother merge of the surfaces. You have to be sure to spray directly over and not from the sides. You don't want yellow spray on ... [More]

Estes Time Warp Build, #7321, Part 13, Fin Masking
Blog
Most of the masks turned out well after the tape was lifted. There were some scraping back of the black to round the leading edges. Whoops! I had some black bleed around one fin leading edge. The black was scraped off for a touchup. White paint was touched up for a light undercoat. Yellow is a translucent color and needs white underneath. It took three applications of the white. ...

Centuri Alien Encounter Flying Saucer 3/4 Size

Flight
Just as advertised, at apogee it turned over and "floated" down landing on the wire legs. - C5-3 - ROAR, Christmas, FL [More]
New Way Firecat 4

Flight
On dislodged fin at touch down - B6-4 - ROAR, Christmas, FL [More]
FlisKits M.A.C.M.E. Shrew MMX

Flight
It is stable - to about 40 feet. The short MMX ejection fired before apogee. The narrow streamer slowed descent. - 1/8A-1 - ROAR, Christmas, FL [More]
Quest Striker AGM

Flight
I reefed the chute for a faster descent which led to two fins broken off. The lower 2/3 of the fins didn't adhere well to the plastic tail cone. The smaller fairing fins were still securely glued to the body tube. - C6-5 [More]

Estes LTV Scout

Flight
Boost was labored but true. Altitude was probably about 400'. I set the build up with two chutes instead of the single one in the kit. Both ejected and opened. At landing, two of the small fins popped off and were found nearby. - C6-5 - ROAR, Christmas, FL [More]
Centuri Skylab Clone

Flight
The model was rigged for horizontal recovery but the chute lines got tangled at ejection. One solar panel fin and one side booster broke off on landing. Looks like an easy, clean repair. - C5-3 - ROAR, Christmas, FL [More]
Semroc Excalibur

Flight
First launch of the Semroc/Centuri EXCALIBUR with a B6-4. Arrow straight (obviously due to the six fibre fins) to an estimated 400'. No damage when picked up. - E B6-4 - ROAR, Christmas, FL [More]
Fliskits Saturn V MMX

Flight
Unstable! Probably got to 8 feet in that loop. Ejection on the ground and closest to the pad. - 1/8A-1 - ROAR, Christmas, FL [More]
Excelsior Rocketry Honest Goon

Flight
It's a bulky, heavy bird but always comes through. With the C6-5 altitude was around 425'. Full chute and no damage. - C6-5 - ROAR, Christmas, FL [More]

Build Entry
The A Frames and Fins were pressed together. The C Frames are pressed into the A Frames and Fins. Be careful handling the Fin paint while assembling. Silver or metallic paints are easy to dull with fingerprints.
