I started a similar thread on YORF but I thought I would ask the same question here.
This will be the first National Rocket event I will be attending that hasnt been in Pueblo where I live. I was just wondering what new or old models some of you are intending to bring. I started to build myself some new models a cople weeks ago so I thought I would share what Ive got done so far. Since Ive got almost two more months to go Im sure Ill build a couple more smaller models as well.
From Left to Right.
This one is a sport scale model of the DoorKnob. It uses an Estes BT-101 body tube and a nose cone from the Estes Maxi Brute V2 which I found to match the contour better than a standard Ogive. It has through the wall 3mm birch plywood in the center of the fin with 1/16 bass wood on both sides. The leading edge is tapered. The motor mount is 29mm. The next model is the Estes Maxi Brute V2 with a 29mm motor mount. The vacuum formed fins are reinforced along their inside edges with epoxy resin and chopped glass so they are much stronger then the originals. Next we have a BT-20 size Scissor Wing Transport for 13mm motors. The last one on the right is a 4 diameter upscale of the Estes Goblin. It has through the wall birch plywood fins with 3/32 sheeting on the sides. It too will use a 29mm motor mount. Up front we have intakes that are simply tapped together in the image for a 3 diameter upscale of the Estes QCC Explorer. It too will have a 29mm motor mount.
This is what Ive got going, so lets see what the rest of you are bringing.
