    My LOC 7.5 Goblin arrived the other day!

    I love the custom two toned bat logo on the box!

    I have 6 rockets that need to be finished before I start this beast.

    I kinda have to laugh at these boxes.. it's a large box with hollow tubes inside! A lot of volume for little actual material.

    Although the kits are cool, the box art is also pretty cool too!!

    Okay, the tubular nylon shock cord connects to the eye bolt on the top centering ring and the other end to the nose cone and parachute. Won't the tubular nylon shock cord get singed by the ejection charge? I have a nomex blanket to wrap my chute, but what about protecting the shock cord?

    Yes, and that is why I always use a short section of Kevlar (1000-2000 LBF) from the eye bolt to just above the top of the body tube. In addition, I add a small (~3") piece of material on that Kevlar at the top (near the BT edge) for wear protection.

    Just wondering how much nose weight was added for your LOC Goblin? Based on my RockSim model, I'm finding ~200g works for 38mm and 1-2 grain 54mm motors.

    I flew mine on a I245G using the LOC 38mm adapter with no nose weight. Then the LOC boys and I aired them out at Bong last weekend. I flew mine on a K456DM, and the LOC boys upped me a little by using a K535W DMS. Mine went to 3956', and the LOC boys got ~4100' ish. No epoxy in my rocket at all. I did shake the external fillets loose. It pulled almost 24 G's. I'm gonna pull them off and use TB III this time... I think the Mould and Trim didn't soak in good enough.

    I just picked up a Goblin from my local shop for a winter project. Looking forward to my first LOC build!
