Rocket Launch 07/03/21
The 4th of July, holiday weekend, was a great time to be launching rockets. The temperature was in the mid 80’s, with the humidity lower than normal, making the breeze feel great in the shade. The winds were not to bad and we had a great time as always.
Rocket Launch 06/05/21
Beautiful day, humid, 85 degrees with hardly any wind. There were some dark clouds, later in the day, and it started to sprinkle around 3:45. We had another great day flying rockets.

Drill Bit Sizing Chart
Drill bits are used to remove material to create a hole. There are several considerations like the spiral (rate of twist or how it controls the rate of chip removal), the point angle (harder materials require a larger point angle where soft material require a sharp angle), the lip angle (the amount of support provided to the cutting edge)

Estes Super Vega Repair
Estes Super Vega is the upscale version of the Estes Starship Vega (kit #1320). It was designed by Wayne Kellner and first offered in the 1979 catalog for $6.50. The Super Vega (kit #2036) released in 1990 and is 36″ in height compared to the Starship Vega at 20″. Mine has flown great for years but would take some serious damage on the landing pods and the legs were constantly breaking off. I previously wrapped the landing pods in fiberglass. Now to work on those legs.
