An ingenious solution for securing the fin tabs at that angle. Thumbs up!!
I’ll go you one better. Cut a 3/8” length piece of whatever motor Mount tube is, cut a lengthwise segment out (just enough so it will roll up INSIDE the same size tube without overlap. Slightly too BIG a cut is better than too small, you don’t want overlap.Tip: You can peel away about half the thickness on the motor blocks, just take some needle nose pliers and take it off the i.d.
both true, not necessarily a deal killer.Rotating the fins 45 degrees would have the fin intersecting the motor tubes at an angle and not perpendicular to the motor tube surface.
Rocketarium cones?I got my tubes and cones in the mail so builds #4 and #5 are making more progress. Build #4 is BT-70, build #5 is BT-80.
I think they both are, from erockets.Rocketarium cones?
Aha, just checked and see the Rocketarium cones there. I hadn't known erockets carried them.I think they both are, from erockets.
All things considered it turned out to be more work and problems than I wanted. If I had not gotten so far into it I would have probably rotated the pattern 45 degrees so that 2 of the fin tabs were longer and extended to the valley between motor mount tubes. But I already had the fins made and papered by the time that came up.Also really like your solution to the four fin cluster engine mount.
Lovely Sapphire. Re. Fat Boy, I wonder if there's a market for water soluble shock cords and shroud lines.In other news the Fat Boy is probably still hanging from a very tall tree in Arlington. It has a kevlar shock cord so it probably won't come down anytime soon.
Probably not, at least for LPR rockets. As the rockets themselves are usually made of water soluble materials (cardboard, paper and wood).I wonder if there's a market for water soluble shock cords and shroud lines.
Eventually the body of that one will come down, by then nothing will be usable except for the engine hook. The nose cone might come down then, or the kevlar might be tangled around branches enough that it would never come down. That rocket body is built with big glue fillets and fins extending to the motor tube so it won't come apart very fast.Probably not, at least for LPR rockets.

Sorry I missed seeing that flight. Was once again too busy to make it to the launch. That's a beautiful liftoff, and I'm sure the whole flight was spectacular.I was finally able to launch the Double Nova today on a pair of D12-5. This turned out to be a great combination with the rocket flying straight and to a decent altitude for my purposes. My sim said 875 feet and it seemed to get all of that.
