Actually John, I’d be just as happy with convolute-wound glass. Two 48″ x 4″ sticks and 12″ of coupler. How much for that?

Rolling tubes isn’t so hard. Rolling GOOD tubes, especially larger than 54mm is very difficult.I was hoping John that you would be a reliable source for PF tubing – I need about 7′ of 4″ carbon and 1′ of carbon…   Read more»

I’ve come to the conclusion that Curtis is incorrigible. Not a single attempt at an order has come through in any kind of reasonable time frame. Nearly every one required multiple phone calls – some bordering on very nasty. A…   Read more»

Hmmm… I like the idea of epoxying in a piece of arrow shaft or something. That would work on a lighter weight bird. You could even drill a hole through the airframe before inserting it and epoxying it into place.

Yes Bret. Drill some 1/4″ or 3/8″ holes in the bulkhead.

Well, if not an eyebolt in the motor case, my other choice would be to build the booster section zipperless and install the eyebolt in the forward bulkhead.

Congrats Daddy….

Wilke still uses the free version of Rocksim 4.0 I think.

At least with Rocksim 7.x I’ve seen that the manual optimization works far better than the automatic. Rocksim 8 (paid for) doesn’t work on any of my systems at all.

Looks cool. I expect it would be quite heavy compared to an equivalent composite or paper/phenolic rocket.

I’ve seen carbon tubes fly that were a single wrap of 5.7oz fabric. You could nearly flatten it with your fingers, but it was rigid enough for an H motor. It is a matter of what you’re trying to do….   Read more»

I have 2 or 3 old AT I69’s and a half dozen G55’s… one of these days I’ll have to fly them.W

John, without those extra hands and fingers in there holding things and mixing epoxy and such, I don’t think those jobs would have worked out nearly as well.By the way, be sure to bring unLeashed with you to the meeting,…   Read more»

Yes. I made some 1/16″ plate from it a couple years ago for someone. Works just like plain fiberglass pretty much though I recall it being more like carbon as far as wetting it out – the epoxy didn’t soak…   Read more»

Bruce, my Aeropoxy lite has been around for 4 years and is most definitely still good after being stored in the garage the whole time. I swear by this stuff and it is the best filler I’ve ever used. Pot…   Read more»

This is the stuff I use.http://www.fibreglast.com/product/Polyester_Release_Peel_Ply_583/Vacuum_Bagging_Films_Peel_Ply_Tapes

I use teflon coated polyester fabric for peel-ply. Breather fabric is breather fabric – essentially the same as what quilters use to fill between the layers of their quilts.I use Fiberglast.com or Aircraft Spruce for my supplies. Good prices, quick…   Read more»

I lay up all the tip to tip for a given layer at once – sometimes 2 or 3 layers on each even now that I’ve got the procedure dialed in.Picture a 3FNC bird – number the fins 1, 2,…   Read more»

This was obviously NOT an optimized design, but a platform to test a variety of things and given a few “experiences” during the years leading up to my L3, I wanted something that would survive a fall from significant altitude….   Read more»

Those U-bolts are there purely for backup in case the eyebolt in the motor closure fails or unscrews itself. I use 1/4″ quicklinks – 1 per U-bolt and I have a short loop of sewn kevlar set up in a…   Read more»
