Sparkfun has a 9DOF board - 3axis accelerometer, 3 axis rate gyros and 3 axis Magnetic (compass). That plus an Arduino or other small micro-controller and servo-controlled fin tabs might make a dandy ...

Balsa end-grain is almost as light and considerably stronger from my understanding. Another option to consider is foam-core fins. I built a fin can for someone a couple years ago made up of a skeleton...

I've worked with the stuff and plan on an M-powered bird that will fly with 1/8" Nomex honeycomb fin cores. Unfortunately I don't have a weight for you. I plan on putting beveled G10 strips for leadin...

Quite frankly, traipsing about the prairie searching for rockets has never been high on my list of enjoyable activities. GPS saved the hobby for me.

I will add one thing here. Making plate stock for fins or building integral fin cans isn't difficult. Both can be done without v-bagging or other fancy techniques of any kind. For most sport rocketry ...

I might add that Adrian's comments are good - particularly for smaller jobs. My first v-bag project was a 24mm altitude bird and was done with a shop vac, plastic garbage bag and duct tape with a klud...

Right now I'm waiting on some Nomex honeycomb fin cores from Giant Leap. When those turn up and I get the airframe slotted, and then post a Saturday date for doing a v-bagged layup. I'll be happy to h...

Given the amount of interest in this the last year or so, I should probably do another class. I have a vacuum pump I bought reconditioned from Aircraft Spruce for $150 that will pull 25-28" of Mercury...

My DC-20 is mounted flat on a bulkhead with the antenna going straight up into the nose cone on my 5" bird. Even uses the same mounting screws.

Actually one of each would suffice as would a 9" coupler although the 12" would be better as I need a 2nd short piece of coupler and figured to cut it from a longer chunk. I definitely one piece 48" -...

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...

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 b...

My congrats too Sean...

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 ...
