2024-04-21Goblin Deez, 4" Loc Goblin  Flight Preflight, inspection, and launch were all nominal. I used the UDDT to drill out the delay to 6 seconds. I must have not done it correctly, because the delay was ~ 10-12 seconds. The shock cord zippered the body tube down both sides of the camera, destroying the rocket. I MAY be able to repair it ... [More]
Maximus Periculum  Flight Great launch and ejection. The parachute failed to leave the body tube so it streamered down. The chute was found to be outside of the BT at the crash/landing site. unknown why it got hung up. I will use generous amounts of baby power in the future - G74-6 [More]
2023-10-22Mega - Post Launch Report Build Entry Before giving the launch report, I wanted to mention that I was still tail-heavy. Even after adding the modified IPL nosecone avionics bay/sled. One of the mods I added was a 6mm hole at the very top of the sled. I cut a piece of all thread to size where it would fit into the tip of the nosecone. ... [More]
2023-10-21Goblin Deez, 4" Loc Goblin  Flight Great launch. DMS Delay was too long even though I drilled it according to specs. No damage as a result, though. - H130-6 - CRASH Launch Site [More]

2023-10-01Mega Build This build was based off the Estes Der Mega Red Max kit originally created by Estes. I was fortunate enough to be able to purchase a 4-in nose cone and body tube, which were available from their website in September 2023. I secured a plywood upgrade kit from Rocketry Works. All the other parts I ... [More]
Mega - Decals Build Entry I created the decals by scanning the waterslide decal sheet from a standard Der Red Max kit. I converted this to SVG and imported it into Cricut Design Studio where I resized them (sort of) to scale. the black band around the forward end of the body tube and the squared-off crosses are spot on but ...

Mega - Stability Issue Build Entry I have decided to cut the bottom of the nose cone off and fit the IPL ebay. This will also give me interior access to the nose cone to include a counterweight system. The top of the ebay sled has a hole for 1/4-20 all-thread that will allow me to capture weights above the ebay between two nuts. ... [More]
2023-09-13MegaMax Build The two rocket designs that I just love are the Goblin and Red Max. I have built several Red Max versions but I wanted one in a big boy format. Since the only kits available are astronomically expensive on Ebay, I decided to scratch-build this one. Here's a list of the parts and where I got them: ... [More]

2023-09-12Cookie Monster - Doorknob Scratch Clone Build Based on the Estes Doorknob kit, I scratch built the Doorknob clone called, Cookie Monster. The build thread can be found on The Rocketry Forums [More]
2023-09-03Cookie Monster  Flight It was a beautiful day to fly a beautiful rocket. Well, until launch. I measured out the CG which seemed fine but later discovered that my CP was further up than I initially calculated. This made the rocket just on the cusp of unstable. After the rocket cleared the rail it started to wobble, not ... [More]
2023-08-19SpiderMax  Flight Great Flight with beautiful blue flame from the Blue Thunder motor. Recovery was uneventful (in a good way). Unfortunately, upon arriving back home, we noticed one of the fins was cracked. This is very difficult to repair (maybe fiberglass). It is unclear how the fin was broken but the onboard ... [More]
2023-08-06SpiderMax  Flight The flight was unstable because the stock nose cone was used. The rocket made two loops and then lawn-darted - G74-9 - CRASH Launch Site [More]
GoblinLicker Flight Perfect flight. Up and down was as good as it gets - D12-5 - CRASH Launch Site [More]
2023-07-24Balerion - Goblin fincan bashed with custom Nose Cone - Same Great Taste Just a Different Color Build Entry After the rocket gods took Mk1, I ran another print for Mk2. I tweaked the print just a bit, but nothing of consequence. [More]
Chimera MK2 - Maiden Flight Build Entry I launched this on an F67 at Hartsel, Colorado and it flew amazingly. There were no electronics on this one so I would estimate the altitude to be around 1,200 ft [More]
2023-07-23SpiderMax  Flight The flight was sub-optimal but successful. The rocket shed some weight at launch by dumping the onboard camera onto the ground at the pad. Then the motor case was ejected from the rocket because of several issues: The retention cap was too deep (tall) making the motor nozzle recessed and this ... [More]
SpiderMax  Flight While this was a successful flight, I had many issues. At preflight, I noticed that I had the extended 29mm retainer cap instead of the shorty. I should have taken note of the difference because this plays out later. I used the Eggtimer Quantum Altimeter, Estes Altimeter, JollyLogic Chute release ... [More]
2023-07-21Balerion - Goblin fincan bashed with custom Nose Cone Build Introduction: I found a couple of different 3D models that I have been tinkering with and came up with Baleron. The fincan comes from Digbaddy's Estes Goblin - BT60/29mm Motor Builder's Kit and the nose cone was sourced from Vecinimod's Minimum Diameter High Power Rocket . I used ~ 180mm of BT60 ... [More]
2023-07-02Chimera MK2 Build Same as the original Chimera with a shock cord retainer integrated. I also build an EBay for the center tube but I want to test the airframe before employing that. The middle tube can be screwed onto the top and bottom tubes and the Ebay is also retained with screws. I built a passage under the ... [More]
Chimera - 3D printed Build I found the model for Chimera on Printables . I like the concept but I wanted to modify the MMT and retainer, so I beefed up the fin can, so it would accept a 29mm MMT. I also printed one of my go-to retainers and assembled it. Printed in PLA+ with black for the nose cone and fin can, and the body ... [More]
Hobgoblin - 3" Goblin Build 3" diameter Goblin clone, upscaled from Estes Goblin kit. I started by 3D printing the fins with notches for the centering rings (also 3d printed) on a 38mm MMT. The motor retainer, nose cone (3pcs) and the electronics were also 3D printed. Once I got the tube slotted, I felt like I wanted ... [More]

2023-05-07SkyLicker XL - Maiden Launch Build Entry Had two launches today (5/7/2023).
The maiden flight was on D12-5. The estimated altitude was ~35m. It was very slow coming off the launch pad. I suspect the thrust to weight was pretty low but it was stable. The parachute failed, which has now become a tradition ... [More]
2023-05-01ESAM-58 Xtra Special Build I will be modding this kit with 3d printed:
* centering rings
* motor retainer
* shock cord mount
* fins
Also, I am upgrading from 18mm to 24mm for extra boomies
Pictures will be posted throughout the build and 3D files posted to my Printables account after ... [More]
2023-04-15Banana Bitch Build Using my 3D printer, I printed the nose cone and fin can from a file on Thingiverse (https://www.thingiverse.com/thing:2840419). Added: Kevlar thread shock cord 12" Parachute No motor retainer so the motor needed some masking tape on the backend to keep it in place. Note: On the maiden ... [More]
