    Well, the fact that it appears to be intact, in the second photo, suggests a successful flight . . . Looking forward to the video !

    I need to get mine built. I have the SpaceX falcon 9. I also have the boyce heavy conversion parts. Just to many rockets in th pile. Honestly, I think I may sell a few.

    Nice flight! I see that your video is also on the Boyce Aerospace product description page for this upgrade.
    Hmmm, wondering if anybody thought about clustering this baby? Or is it just me?:D
    Cheers.

    Leonard, I see in your build that you used all four of the original clear fins: Two on the donor core and two on the outboard boosters.
    But I was reading the assembly instructions for the upgrade and they say to use only two fins attached to the core.
    Did you add the outboard fins for extra stability? I'm wondering how stable this will be if I follow the instructions to the letter.
    Because I have yet to see a stable two finned rocket. Thanks.

    That's pretty cool, and lighter than I thought it looked. Definitely wouldn't have pegged that as an E12 black powder flight

    For you builders out there, I did get a reply from Boyce. The outboard boosters act as a set of fins, so the upgrade is stable using only two of the plastic ones. He says that some builders have used four and reduced the nose weight. Think I'll sim a cluster and see if that will work. Laters.

    I was worried about the stability so I added the 2 other clear fins to the side two boosters. It would have been unfortunate to see this one come off of the pad, take a horizontal turn and coneplant in the dirt. I see you contacted BA and found 2 fins would work. I was too chickens**t to try that. 4 worked just fine. I did think the rocket was underpowered with the E12-4. Thoses are the largest motors I use. I have not grauduated to anything larger. Especially re-loadables. I lose too many rockets already to start leaving that kind of money in the live oak trees around Charleston SC. The field I launched in will not be there too much longer. It's a industrial park outside of Charleston and a new warehouse is going up soon.
