Hi John,John Reilly flew his Callisto on an I200 in the 29/360 case last November. I only ever had one set of 29mm closures, and I don’t recall there being an issue with the nozzle fitting in the closure. We…   Read more»

I have one of each but I’m afraid of having to clean that long freakin casing…

Bottle brush, followed by bottle brush with wet wipe over the end. Piece of cake! Now fly the silly things!Ken

I’ll buy the H268 from you if that casing cleaning thing continues to overwhelm 🙂 Just curious, can you tell by looking which closure they need?

Uh oh! 2005 was the last time someone burned an I200 or H268? Wow! We have been slacking!Art

Thanks – I’ll get w/ Tim T. and see if he has any? There is a chance that what he has in stock is sized to the older nozzle?JW

I’m curious if anyone has flown an H268 or I200 lately?I checked the launch logs directly and it looks like nobody has flown either of those at a club launch for a few years.+ + + + + +| event…   Read more»

Those rockets by Brad Vatsaas have got me thinking really crazy thoughts now…to hell with TFNC!!!I’ve already started on an upscale version of this scratch built rocket…5x 29mm and you get the idea. going to have to do single use…   Read more»

That is a pretty good start….Thanks

about the best site I’ve seen for this kind of thing is//www.dars.org/jimz/rp00.htmmore links for cool upscale info can be found at//www.oldrocketplans.com/perhaps the end all be all master of upscaling is Brad Vatsaas//www.vatsaas.org/rtv/hope that helps!

This item has been SOLD… thanks for the inquiries– JW

Well Doug, you have even more admiration from me – I’ve been using the cool tools since I’ve had access to them and would have thought you had some access to them given your job. Even more power to you…   Read more»

drew things up in either Solidworks or Pro/Engineer and had the software figure out the intersection shapes and possibly even make cutting templates or exported it to an NC tooling package like MasterCAM to cut the partsActually don’t use nearly…   Read more»

BTW, this project is called Double Feature named by John Wilke. Glad I could help 8) I’ll get out of your way now.This is probably the most complex rocket I’ve ever seen attempted? I feel like a total hack when…   Read more»

Doug, as always, I stand in awe of your projects. I thought I was gonna be the new cool kid at the launches with my NC machined parts. You’ve gone far beyond that.Warren

BTW, this project is called Double Feature named by John Wilke.Here is looking up the old wazoo. There are spars that run from the center motor mount tube to the outboards.A shot of the motor mount tubes without the skin…   Read more»

a.) how did you discern the pattern for cutting the tapered holes into the bigger tube? I assume this mathmatically derived… I’m just curious how you even begin to derive the pattern for where to make the cuts?Technically an ellipse…   Read more»

I would bet looking at what Doug has shown that he drew things up in either Solidworks or Pro/Engineer and had the software figure out the intersection shapes and possibly even make cutting templates or exported it to an NC…   Read more»

Slicing a cylinder you should get an ellipse. In this case you’d be slicing the motor mount as your cylinder. Then you’d get your ellipse and could draw that and transfer it. 🙂 Just one way to do it -…   Read more»

Doug, that is beyond amazing. Two questions:a.) how did you discern the pattern for cutting the tapered holes into the bigger tube? I assume this mathmatically derived… I’m just curious how you even begin to derive the pattern for where…   Read more»
