As a matter of club policy, the only acceptable altitudes reported for club record purposes is the direct, unmodified and unprocessed output of a stock, unmodified commercially available altimeter uti...

I absolutely agree - what I and other amateur composite folks do pales against properly engineered composites. However, were recovery impacts considered in the layup design? I, for one, because I don'...

Doug, Have you thought about a layer or two of Kevlar at the ends of the upper airframe? Far more able to take impact than carbon or fiberglass. Of course you have to cover it with at least one or two...

Very interesting... and I would say a prime motivation for adding an ambient air temperature sensor and data point along with every altitude data point. This certainly makes sense to me. I had long he...

After seeing the parts in the back of Art's car at the February launch, I knew we were in for something special - between Art and Dougs skills, there are two of the most experienced large rocket build...

I might be very interested in this bird Mike. I've been wanting to do a big EX Hybrid, though it was somewhere down the road in my plans. What remains to be done to complete the bird? What about GSE c...

Use Cotronics high temp epoxy on the leading edge of the fins and the tip of the nosecone. There is insufficient heat soak during a flight to cause significant softening of the epoxy although at the s...

I found the only way to deal with the tape sticking too well due to heat is to remove the motor while it is still warm. I actually destroyed a CF fin can and fins trying to remove a motor stuck to it....

Historically we've always accepted NCR member flights regardless of where they are set so long as the witnesses are NCR members as well. Warren

Congratulations Adrian, I stand corrected. Get me the info and I'll update the records page. Warren

Mike, I'd definitely be interested in reloads if you have any that fit AMW 54mm or the AMW 75/6000 cases. Warren

Mike, A fully appropriate use of the forums - fear not. I will admit, I'm definitely saddened to see you stepping back from the hobby. On the other hand, I do know how other hobbies can distract one f...

For Estes type paper tubes, I use a small miter box and an X-acto razor saw. Need to do a little touch up with 220 sandpaper afterwards and then you're good to go. Welcome on board. Warren

I have sketches for a design for retractable rail buttons that would pull back into the airframe as soon as the button leaves the rail. Unfortunately, the spring tension in the current would be compre...

A guitar player in a band I played with back in the 70's pulled a radial arm saw almost all the way through his hand (someone yelled for him as he was making a cut and he looked up and kept pulling). ...
