The lonely life of a theodolite
A panoramic shot of LUNAR’s Snow Ranch launch field in Farmington, California starring one of the club’s theodolites, used for tracking altitudes of contest models.
In a sketch prepared in November 1964, Dr. Wernher von Braun envisioned developing a Saturn V S-II Stage into a space station.

C Dual Eggloft Altitude
Diagnosis of a total failure! The piston failed in one of the very infrequent but sometimes happens cases. The piston head became stuck about 6 inches behind the motor, where the motor thrust burned through the piston tube. No piston assist plus the additional loss from having to free itself of an unsealed piston meant the rocket was not traveling very fast at all when it left the tower. Ejection was way past apogee and the model suffered a lot of damage. Then it hit the ground, causing scrambles!

1/4A Helicopter Duration
This is a really tough event. Building a small, light model that can coast for 3 seconds, deploy blades and then come down slowly is quite difficult. The easy way out is to build a Tasmanian Devil, as shown above. No moving parts, and my biggest problem with these models is that they spin so fast the blades will come off in flight sometimes (okay maybe that is only a problem when you put D and E motors in them).
Anyway, above is the 13mm build of this plan:

Trip Barber’s NARCON 2013 talk about International Rocketry Competition, long but lots of details!
He (and Chris Flanigan) recently put together this huge and incredibly detailed site on FAI competition: https://sites.google.com/site/xfaispacemodeling/

Pretty cool post about rockets (and airplanes) from the UK. I have a model of the Black Knight, but it has a different (less cool) color scheme.
Some might find this interesting.
all of these are test prototypes produced by Companies in the UK that have been Years ahead of their time yet the Government has pulled funding and candled the projects. Total madness.
1&2. Black arrow / black night rocket. A full operation orbital delivery system that successfully placed a communication satellite Prospero into orbit (1971) built and deployed entirely by the British. Interesting fact this was a HTP system requiring a smaller engine and fuel capacity. The black arrow variant was a long range ICBM capable of transcontinental flight. This was candled when the UK government purchased trident from the US. (Great idea spend money when you could provide jobs and stimulate own economy)
Building a reliable, dependable rocket for Set Altitude
160 meters or 1/10th of a mile is the target with C motors.
