Does anyone have the tube fin layout dimension for the King Kraken? I have some LOC airframe and centering rings laying around for a scratch build. Thanks!

During HPR launches I usually slow down a bit with a more laid back mid power flight. I have a Big Daddy that rocks on a 24mm CTI F50 skid mark. So I decided to get a second and convert it to 29mm power. I papered the fins, added some nose weight, Estes PSII 29mm mount and Aero Pack retainer...

My daughter is a big Steelers fan and she asked If I could build as rocket for her with Steelers colors and logo. I chose the Mini Magg for its billboard style dimensions. The rocket is finished in automotive base coat /clear coat with graphics by Stickershock. Though it is equipped to fly...

The second launch of my MAC Peformance 3FNC at URRF 6 found the very full and flowing drainage ditch not far from the away cell. When I first got to the rocket, the airframe was floating with the recovery harness and nose cone snagged on the bottom. Mike Crupe and I returned with a telescoping...

How can I get a motor motor file to be added to Open Rocket. I saved a Rasp. file on a Loki H125 Cocktail, but cannot figure out how to get it into my motor selections...

I have never figured out how to add stripes, color breaks, logos or text in the "appearance" tab in Open Rocket. I can color the major components, but thats it. Would appreciate any tips to get started.

Looking for a Rocsim or Open Rocket file for the Estes Monarch. I am looking to upscale.

Pouring rain here in Central Illinois the past week, so abandoned plans to paint a HPR build and pulled Super Big Bertha from the build inventory. What a great kit. Love the laminated fin design.... just like the Mega Der Red Max. Would be great to see more PSII issues with this construction...

Does anyone have the Rocsim or Open Rocket file for the Estes V2 BT80 size kit ?

For some reason Open Rocket is to saving my simulations. The sim files on my older rockets are still in tact. Any thoughts?

My MAC Performance Rayzor took a core sample at Potter last June as a result of a failed apogee charge. Proved to be due to a bad e-match. No resistance reading on the Ohm meter. I got a new payload section, coupler and upgraded to a Wildman FWFG nosecone. Fortunately, I had paint left over...

Curious as to why there are several ancient posts that lead the Hi Power TRF posts. Titled "sticky". What gives with these posts?

About a year ago I ordered some heavily discounted PSII kits and airframe parts from Estes. I concocted the Eclipse from Estes Argent airframe components, built a baffle into the aft coupler, beefed up the transition harness anchor point, added a 1/4 inch kevlar harness tag ..... and fins cut...

I just received the first release of the new MAC Performance Ethos 2.0. It is a longer, lighter and simplified version of the original 4 inch diameter ETHOS designed around 38mm power in a singly deployment configuration. It will fly on larger G motors, but is also a great L1 cert platform...

I just received the first release of the new ETHOS 2.0 from MAC Performance Rocketry. It is a simplified version of the original 4 inch diameter ETHOS but is longer and lighter and will fly on a wide range of 38mm Motors (large G through I and up to J for the experience flier) in single deploy...

Flew my MAC Performance Rayzor on an Aerotech J350 Sunday at URRF4. The "Up" part of the flight was perfect and in the exact direction I wanted for wind drift. Unfortunately, the drogue section did not fire. The rocket came in ballistic. The main deployed at 80O feet and we saw the chute...

I installed a MW screw switch on a MW altimeter bay sled. The screw doesn't appear to have a means to resist turning out of contact. I could foul up the treads a bit, but before I do I would like to know what other users have experienced.

Does anyone know what the latest news is on CTI motor production? I need 54mm hardware for a new build. Have been flying CTI 38mm and like the ease of loading and flexibility of the spacer system. My concern is motor availability. Lots of empty supplier shelves from what I can tell

Drove 776 mile to get my L1 and L2 certifications at the recent URRG launch in Potter NY. The Mac Performance Rayzor flew to 3,974 feet on a CTI J285 Classic. Thanks to Mike Crupe for mentoring my progress in HPR since April and to Dave McCann for the great photo work. Also thanks to Dutch...

Is Tripoli Ft Myers still alive? The last pics on there web site are from 2013. I am looking for an HPR launch site as close to the Florida Keys as I can get.
