Chris,Yes the shaping has me headed for balsa as thats a lot of tapers, maybe next project I’ll look at some of the foams (dinylcell, etc), has great compression strength and reasonable shear resistance. Wish I could figure out a… Read more»

I’d go for the balsa in this case. Easy to shape, and phenomenal compression strength (end grain). Honeycomb might be a pain unless it is foam filled or used with prepreg.Should be an incredible project – I can’t wait to… Read more»

Why not bring it to the NCR Meeting and Swap Meet and find it a new owner. We’ll be meeting at the VFW Hall in Ault on January 13th, doors at 11 and meeting starting approximately at noon.

You’ll hate this… I had one, too. And I still have it, made to carry telemetry transmitters. Yes, I desicrated a classic kit! Still have the box it came in, full of body tubes now. As far as its… Read more»

Keep in mind that CJL thinks every 29mm rocket needs an H268… 8Oof course he’s probably right too , although I favor the I200 myself. A full 29/360 is the important part :DToo much, he got grief from me over… Read more»

Agreed about the rail buttons.They will provide a nice, stable platform for it and prevent any rod whip.It would definitely scream on a nice H motor – H268 perhaps 😯

8) I too have a Can. Arrow. I added Ply fins and foam to both the tail and nose. The nose foam hold a large bolt for the recovery harness, and adds needed weight. I also added a full coupler… Read more»

Well, if you were going to do a tower launch, you would need something to guide all 4. However, I would just go with a launch lug, as a canadian arrow/v2 design is hardly an optimized MD screamer, and will… Read more»

Maybe the idea of limiting to 2 rockets is because SOMEBODY has the club records for F-J with 5 different rockets?

This is a GREAT idea and it sounds like it would be a wonderful event. That said, we have had a really hard time getting folks to even fly their single solitary SSS or SSSS shot each year…. doing ten… Read more»

Make it even more fun and require a different rocket for each motor size, regardless of whether you have an altimter reading for the smaller ones. Recovery of each has to be accomplished before the next size up is launched…. Read more»

Would all motors have to be individual flights? Can you say mixed cluster? I knew you could! :DThat might be a quick way to use up the smaller motors as strapons, etc. with the bigger motors. Since most of the… Read more»

why even have a weight limit? the altitude penalty extracted should suffice IMO. The other thought I have as opposed to cumulative altitude, you get place points for each impulse, and the total number of points wins. This then equalizes… Read more»

I would say you have to fly all 10 motors. If you did your A-F/G motors motor eject with altimeter for recording only. Your H, I, J would be DD. You’d have to be ready to fly when you got… Read more»
