For Christmas, I got the 4 BSD Horizon. This kit is great! The rocket features a 4 inch plastic nosecone, strong 4 inch airframe tube (kind of like LOC tubes), 38mm MMT with 29mm adapter, 3/16 plywood fins, tubular nylon for shock cord, eyebolts for attachment of shock cord, 30 chute, launch lug AND rail buttons, vinyl decals, and blind nuts and hardware for motor retention. Construction was fairly easy. It was just like building a giant size Estes kit. I first assembled the MMT tube, which involved gluing the CRs to the MMT. Next I installed the blind nuts and the eyebolt. I forgot to get a picture of this assembly before I glued it in place. Sorry guys! Next, I hand cut the fin slots. I test fitted the fins for a proper fit and they fit well. I took the fins out and epoxied the MMT in place. When I first got the kit, the CRs and the bulkhead were too tight of a fit to insert them into the rocket, so I sanded them. I sanded the bulkhead perfect, but I sanded the CRs a little too much and they were too loose to stay in place while the glue dried, so I took a small screw and screwed the CR in place temporarily until the glue had set. Next, I took out the screw and epoxied the fins in place. After that, I put the eyebolt into the bulk plate and epoxied the bulk plate into the tube coupler, which was also a little tight of a fit. I have decided not to glue the tube coupler into the payload tube yet until I decided whether or not I will attach threaded rods so I can use the payload bay as an altimeter bay. Next, I tied the shock cord in place. The shock cord is very long, about 18 feet long! After that, I installed the rail guides. I put the aft rail guide in the hole where the screw was that held the CR in place. I put the other rail guide 6inches down from the top of the airframe tube. The only thing left to do with this rocket is pour glue fillets, pour glue over top CR, finish payload/altimeter bay, epoxy rail guides in place, paint the rocket, and apply vinyl decals. I will fly this rocket on a H165R for its first flight. This is a great rocket and I recommend it for anybody who wants a simple, yet large rocket to build. If built properly, this is a great L1 and L2 certification rocket! I love this rocket and I cant wait to launch it!
