Re: So what do people want from a "flight computer" ?

I agree that $50 is a rip off, dunno how that happened :-( I hope to get one together and start testing in March, hence the need for some G64 & G76 reloads. I reckon doing really well I could get the board up in a rocket at Doonside 6 times/mnth or more if they go along for a ride in some other ...

Re: PCB Manufactures

Not sure if I already mentioned it but futurlec dropped their prices substantially just recently ie just after I ordered some...... I will always make the first 2 or 3 prototypes at home using the kinsten process. However, now knowing how cheap it is to get them made I'd probably pay to get them mad...

Re: Mythbusters rocket sled

It is a great demonstration of E = 1/2mv^2 ie kinetic energy is proportional to v^2 !

Frightening thing is that the US navy now have operational rail guns pushing projectiles at Mach 8.

Re: Oh Yes!.............We truly ARE committed!

Airframes are a waste of time rearwards of the motor's forward closure :-)

On the darkside, typical vehicle construction is a motor case with fins clamped on (or a composite fin can) with some form of airframe attached to the front of the motor.

That doesn't look like a a pressure spike (pressure increase would look like a lower altitude) rather an artifact due to an acceleration pulse during deployment.
