    What did you do rocket wise today?

    Added decals to my rocket ahead of a potential launch this weekend.

    "Starship" - L3 Build Thread

    Good to hear. Wild Thang Extreme looks like a promising choice for me. It's either that or the Darkstar Extreme but I'm a sucker for the way Wild Thang Extreme's fins are designed (similar to this build) and the fact that it should be considerably more straightforward to build. Thanks for the...

    Of course I had to join the Wildman Club, Drago 4 XL looks mighty promising as well.

    Wildman Darkstar Extreme or Wild Thang Extreme looks like a solid choice for a similar build / performance. Anyone have experience with the quality of the kits?

    "Starship" - L3 Build Thread

    I did not think to have the design approved at the time as at the time, I could have it approved for my L3 attempt after gaining L2 experience with it. The rules now are you must get the design approved before manufacturing it so this rocket can just be used to gain L2 experience which is still...

    Yeah I was working off of assumptions from previous rules which is dangerous. Good opportunity to build another rocket I suppose.

    "Starship" - L3 Build Thread

    Well that's a bummer. I remember the Tripoli rule of being able to use a rocket that has previously flown and was hoping that was still the case. Suppose the best way of going about it would be making a new rocket from scratch after approval from a TAP/L3CC. Kind of a shame that I would have 2...

    "Starship" - L3 Build Thread

    Thanks for the reply Steve! Are you familiar with if a rocket that is already built but is documented still qualifies for a L3 attempt? I did not get it approved by a TAP / L3CC before making it as I originally only planned on using it for L2 experience. I would be more than willing to go back...

    "Starship" - L3 Build Thread

    Transferring schools/states has kept me busy the last 2 years, starting to get really settled in now and getting back into the hobbies I was into. Repeating the K is certainly a good idea, it's just the L/M that is a bit conflicting for me. I know the L3 is very complicated compared to L1/L2 and...

    "Starship" - L3 Build Thread

    Long time no see! Planning to get back into rocketry and resume this project / quest towards L3. I think the logical steps would be to get back into launching with a smaller motor (like the K used in the test flight) then moving onto good sized L motors to get a flight profile similar to a baby...

    It was a beautiful day. Perfect day to launch as the weather was great and best of all, no wind! You were attending something a "bit" more important. Hope to see you next month if the weather is nice!

    Best Sim Results, OpenRocket or RockSim?

    Both OpenRocket and RockSim are accurate if you put in the correct data. The leading cause of getting inaccurate results is not measuring your parts individually and relying on an inaccurate model for the simulation. The key to accurate results is to input the mass of all your components...

    Spill hole questions

    Spill holes increase the stability and reduce the drift at the cost of a higher landing velocity. For low power, a spill hole would likely help it recover faster and therefore drift less. Low power rockets typically do not have much mass associated with them so it is very unlikely that adding a...

    What did you do rocket wise today?

    The video shows that there are tabs that go in between the centering rings that hold the fins to the body tube while locking the centering rings into place. Pretty cool idea but I'm sure it comes at a mass penalty with the metal screws and a lot of 3D printed material.

    "Starship" - L3 Build Thread

    My main is set at 900 with backup at 700 for the first flight. Depending on the results the main might be lowered to 700 and the backup at 500. This gives it time to fully open and settle. I'll test with 1.5g but will probably reduce the main charge to around 1.2-1.3g with the backup at 2g.
