    Must Have Tool!

    I wish I had this tool in the 1970’s when I was building my first Estes rockets. I’m using it now to build a Laser X2 for one of my grandsons. The fin alignment guide is easy to use, parts fit well, and a must for getting my fins on aligned and straight.

    Idea good- found it impracticable for my needs

    Getting back into the hobby after almost 50 years , I like seeing new things. I recieved this as a gift and wanted to try it with an Alpha Rocket -

    Probably be ideal if fins were already “set” and didn’t move - when body tube is above base , it created issues.

    I also had a hard time with fins being “perpendicular- and overall found the device to be more troublesome then practical (just my view )

    HOWEVER- once fins were to my satisfaction- inverting the rocket and leaving the fins up to let dry , this was an awesome stand for that purpose

    I will be trying it again as I have a few kits to build before my next STEM event in July. Will update later if better
