    Ring Tail Issues in RockSim

    I picked up a couple of parts from a free parts bin at my local launch, and want to build a ring tail rocket with them. My current plan has a 4 inch body tube and a 5 inch ring tail that is 1 inch long. However, I am dubious of RockSim's accuracy on the matter. Adding a ring tail to the rocket...

    Junior L1 build

    Hey guys, I haven't been too many places on this forum, having joined it late 2019, but because this is my largest project yet, I thought it would be a good idea to share it here, and mabye get some expert advice. It is being built on 4 inch cardboard airframe, and I plan to fly it on a Cesaroni...

    Rocketry clubs in the Kansas City area?

    I live in the Kansas City Kansas area. I currently fly some low power rockets and quite a bit of mid-power, but I would like to get my Junior HPR Level 1 with either the NAR or TRA (whichever has a club closest to me). I am not yet old enough to drive, so the limit of my search range is however...

    Build Thread: New Mach 1 Rocketry Kit, the Nemesis! 54mm BT.

    With all the rainy weather and lack of any high power launches this year for Northern California (last one was Dec. 2018) I've had a LOT of time to build some high power birds. Hoping to have TEN new high power vehicles ready for next weekend's LUNAR launch. Steve has a few new kits and these...

    Can AeroTech Mirage (Modified) Be Used For L2??

    I've got an AeroTech Mirage that went CATO and destroyed the lower half of the rocket. It's originally made for 2G 29mm motors but I modified it to use 3 grain without issue. Instead of just repairing it, I decided to look at upgrading it so I could get my L2 with it also. I have the stuff to...

    LOC Hawk 7.5'' Build Thread

    I ordered the LOC Precision 7.5'' Hawk around Thanksgiving and immediately opened the box without bothering to take pictures. I have already done a few steps, such as assembling the RNWS, but I think I can still do a build thread for the bulk of the remaining steps. I have created a sim file...

    What is considered as "too many fins"? (L2 high powered build)

    I have a 3in thick cardboard tube that I plan on building a rocket around, but to get it stable without an absorbent amount of nose weight, it would require 6 fins on the bottom. Here are some details: - 6 1/8in thick fiberglass fins, 2.5in tall (for anti fin flex) might try 3D printing some...

    FOUND WTB Loki 54/4000 Motor Case

    I'm looking to buy a Loki 54/4000 motor case. I'm mainly using it as an assembly jig/fit check while I'm building the airframe for now (I'm trying to "perfectly" align two separate 54mm motor mount tube sections in the middle of a larger airframe). I don't necessarily need a grain to go with...

    Hermes: Custom 38mm MD Build

    Welcome to my ambitious build! A little backstory: My name is Caden, I'm 18 years old and this is my first year in HPR. I've recently completed my level 2 certification and ever since I've been anxious to move onto something bigger and better (I know I'm another hot shot young guy). Below are...
