Bill, I am experiencing the same problem with making a "mini Guillotine", as it requires a higher degree of perfection and thus more time is required to fabricate the components. This increase adds labor costs which far exceed and savings in material costs. And thank's for posting that fantastic slow motion video which clearly displays how well your invention works! I hope 2017 will allow me to build something so that I can use your innovative creation! :handshake:As Rockdoc indicated, it's starting to get down to diminishing returns and I just don't know if 24mm is going to be worthwhile. I'll probably give it a shot at some point but they can't get much lighter and they can't get much shorter, and as the diameter decreases it gets harder to cram everything in there. It's also true that the cost of making 29mm guides is pretty much the same as the cost of making 38mm guides and I can't imagine 24mm guides getting any cheaper, so I don't know whether the pricing would make them impractical.

Been waiting forever for the 29mm... just snagged one. Looks like he's almost out...
Good to know. I plan on using mine sometime in the near future, and want to make sure I have all the latest tips on how to use them effectively.When properly used, after flexing once to get the rubber bands tensioned correctly and placing the guides all the way aft against the fins, fin strikes are minimized
Groucho, your going to love them!I ordered a 29mm one yesterday for my Mongoose 29 & Go Devil 29 builds. Can't wait to try it out!
That's awesome, thanks! Congrats to you two on the 12283' launch too!
You can see on-board footage of a 75mm flight below which includes a frame-by-frame of the initial boost at the end of the video (this wasn't my flight and I can't remember what motor was used).
Here's my MD M-2245 ejecting your 75mm flyaway guides, they landed about half a football field away from the pad, no damage:We've had success with some very fast motors, including minimum diameter flights with the Loki J-1000 (38mm) and Loki L-2050 (54mm). I honestly do not know what the most energetic M/N/O flight has been. I made a design change after the first few 75mm/98mm guides were made to go from a single rubber band to a dual rubber-band configuration with each band doubled over and the guides spring away more quickly.
