When in doubt... build hell-for-stout!
Which one? I could swear it was through the CG.It was in one of the Apogee papers. Who knows?

It was a report for canting clusters to fly if one motor didn't light. Everyone for years said to cant through the CG, but it turns out halfway between is optimal. Not much of a difference in reality. This would have been around 2012ish. For one motor would there be a difference? Rocket science is hard!Which one? I could swear it was through the CG.
An insane idea, I like it!
And here I thought I was the King (or Court Jester) of the Asymmetry Mole Hill (at least for fin placement!)Point the C/L of the motor through the CG of the "all up rocket" (The front centering ring needs the I.D. hole offset from the O.D. hole.)
Thanks for the tips!And here I thought I was the King (or Court Jester) of the Asymmetry Mole Hill (at least for fin placement!)
If you aren’t going to go with Tractor Motors (one each side of the straight part just before it starts to curve), I think Lake’s got the most viable option.
I think larger fins will help. I’d go with 4, the ventral and dorsal can line up with the plane of the Cane with its curvature, which will also line up with Lake’s motor mount. The right and left should line up with the axis of Lake’s motor mount through the CG, NOT with the straight segment of the Cane.
About the only thing you CAN’T do is name this “Peyronie One.”
I’d also go with one medium to long lug on the MOTOR MOUNT and a second smaller lug on the curve of the cane, again lined up with the axis through the CG.
Decorating tip. Electrical Tape is the only tape I know that can truly make a Candy Cane (or Barber Pole) style helix around a cylinder. Easiest least elegant way is to paint the whole thing white and use red electrical tape to make the red stripes. Alternative is to paint white, MASK what you want STAY white with any color electrical tape (black is usually cheapest). Paint Again With WHITE over the tape to seal edges. Then paint RED. When dry pull the tape.
@Pabsst idea of inverting it would also greatly simplify things, but may not satisfy the Vibe you are looking for. Tapering/pointing the tip will be aerodynamically more efficient. But this ain’t an altitude maximizer bird, so a blunt nose cone, even a bulkhead, would work just fine.
Cool project.
How do ejection charges and parachutes work with tractor motors?
We were planning on painting it white, adding a helix of masking tape, and then painting it red. However, I'll try adding a coat of white on top of the masking tape now.
REAR EJECT! REAR EJECT!The tube pressurizes... and pushes the laundry out. If you were using tractor motors, you'd likely want a rear eject.
Flying the candy cane and then the banana will set you firmly on the path to the Dark Side. Forever will it guide your destiny! Oddrocs rule! Love those crooked rockets!After you master the candy cane rocket, I hope that you move ont master the more common banana shaped rocket.
That makes getting rocket parts soooo delicious!It's not MP yet, but if small tests go well it may eventually be built as MP!

Here is an image of the rocket before launch:Wow, great first flight of the Candy Cane!
It looked like it got more stable as more of the motor burned, so maybe a more nose weight would make it fly straighter up.
Sorry that the ejection event failed. All part of figuring out rocketry. I'm sure you'll have success if launched again.
I may have missed, but what type of motor retention was used?
As long as the rocket plus the G80T weigh less than 53 oz ( 1500 grams ), as I understand it, the only altitude limit would be the laws of physics and the size of your launch site.I think we're going to build a traditional rocket and try to launch it as high as we can with the G-80. Are there any limits to how high we can launch?
