Launched it this past Sunday afternoon on a 29mm Econojet F42-4T. Perfect flight and recovery! 4 second delay was just right. Used two 24 inch chutes.
As I got further into the assembly it became apparent it was going to be significantly heavier than I expected as it approached 500 grams, so I did switch gears on the engine mount. Luckily I was able to cut out the 24 mm mount without too much trouble and Continue Reading
I finished it last night. I used vinyl stickers from Stickershock. Of course after I got all the stickers on I realized I forgot to paint the top of the nose white. Doh! But that’s okay. I might spray it with some dull coat to make the decals not so Continue Reading
Making real progress now, it’s starting to come together. I’m basically following the Estes plans. I epoxied all 6 fins on. I took my time I did them one at a time to make sure they went on straight, which was easy, as Leo did an excellent job on getting Continue Reading
Put the motor mount together. 24mm, I figure if I conclude the E12 won’t lift it, there are 24mm composite options, like the E30. And if I crash it, I might be unhappy, but I can always build another. Since it might fly with an E30, I used a heavy Continue Reading
To help with adhesion of the fins to the body tube with epoxy, I am drilling small holes in the back. To ensure I don’t accidentally drill through the front of the fin I am using my drill press so I can control the depth.
I’ve printed the last pieces from Leo’s files. The cable covers, the charge retainers, and the shock cord plate. The combined weight of these last parts is about 26 grams. long cable cover 9 gramsshort cable cover 6 gramscharge retainer 2 grams eachshock cord plate 7 grams I put these Continue Reading
The Lower and upper fins have been printed. The lower fins weigh about 10 grams each and the upper fins 13 grams. These fins are not scale, they are upsized for stability to match the Estes kit.
I’ve printed the 3 sections that comprise the nose cone. The sections have been dry fitted. My caliper measures my wall thickness as 0.80mm, and the combined weight of the nose cone parts dry fitted is 113 grams in total. Wow, it’s huge!
In the 70s I remember being at Service Merchandise and they had all the Maxi-Brutes, but I had only enough money to buy one. At the time it felt like the hardest decision of my life. I finally settled on the Honest John, but I always wanted the Pershing 1A Continue Reading
