The SSS has NEVER required carbon or composite construction. My first SSS - powered by an H180, was plain phenolic. Every one of my G80 powered SSS birds were either plain phenolic or even paper tubin...

Doug, the issue is that the code does not exist to enter "one more piece of data" - the database schema doesn't currently have the field for it nor does the code that dynamically generates the input s...

The AP bonfire has ALWAYS been an automatically computed result from the input of the flight cards. If it requires anything manual beyond entering the flight card data and occasionally updating the mo...

I'm intruiged by this E9 concept... Low and slow... hmmm. Ideas? Warren

Simple answer is the code, when originally designed, only took into account single motor flights. The launch logs and flight cards that preceeded the code didn't have provision for it and both the ori...

AP Bonfire is determined not by total impulse but by manufacturer's propellent weight. W

The big issue is the motor database needs a thorough clean-up and major additions. I'll do what I can to get it done. Joe is the primary responsible party for Launch Log entries and he should be addi...

Except for the first year of the Single Shot Sweepstakes, we have focused on single use motors. First the Aerotech G80 and then the Roadrunner G80. Personally I feel that given that this is an altitud...

I ALWAYS plug my single use motors that I use for altitude shots. Pull the paper seal, dump the black powder and fill the hole with a bit of epoxy. On some motors I've epoxied in an screw-eye. Warren

Indeed - more Rattlesnakes in one day than I've ever seen - reports of at least 7 individual snakes in a wide range of locations although I personally only saw 3. We saw multiple snakes on the western...

Above D impulse, I do believe you would have to do electronic deployment to get maximum altitude in an optimized design - I think that's a given. For every altitude record I have chased from E on up, ...

Excellent point Adrian. One thought that brings to mind is it seems to me that C-slot and moonburner motors more often than not "wobble" or "wiggle" or whatever in flight, particularly in minimum diam...

Don't forget two things - the principle of moment arm in leverage and laminar flow. Air flow close to the airframe is different than airflow further out. Also, stubby fins in terms of semi-span relati...

How about the Apogee F10? A local vendor, a VERY constrained mass, tight design requirements a given... and the possiblity of 7K or 8K given the 8.5 second burn... The motor is cheap too. Just throwin...

Brad, First - Hybrids are fine for cert flights. Most definitely. Of course you need to have your electronics act together as far as a deployment controller and most folks don't do that until at or af...
