After finishing my Black fly build a couple weeks ago I got the urge to start yet another build! Being a fan of short stubby rockets the Big Daddy is one of my favorites so I have mapped out a design using standard high power components which will end up being a 4" diameter, 26" tall, 38mm replica of the Big Daddy from estes. Parts: LOC 3.9" nosecone. 12.5" long LOC 3.9" airframe. 12" long 1/8" aircraft grade birch ply ttw fins (x4) LOC 38mm motor mount. 8" long 3.9"-38mm 1/4" ply centering rings (x2) 15ft of 1/2" nylon for shock cord. 1010 rail buttons Eye-bolts for recovery attachments. 24" or 30" chute? will know once I get a final weight. Planning on flying this with single deploy, possibly trying out a JLCR for higher flights. I will be modding the nose cone with a bit of nose weight (how much depends on where the cg is at) and also will secure a eye bolt either into a bulkhead that is up in the front of the nose cone or into the epoxy nose weight slurry itself. Either way I will have enough room to house the chute/shock cord burrito in the NC. For motor retention I will be using two tee-nuts in the rear CR and have screws with small metal brackets holding the motor casing in place. Simple diy solution that cost around $1 compared to other motor retainers I have used on my other builds. I have ordered all my components and they should be arriving Tuesday. This morning I took a trip to my favorite hobby shop in PHX, Duncan's R/C, to pick up a sheet of ply for the fins. Duncan's keeps a great selection of rocketry parts and motors on hand! So far I have cut out and sanded the fins so they are all uniform. I have the 38mm motor mount tubing on hand so I will be cutting an 8" section of that today as well. More to come soon!!
