Re: Nike Apache Half-Scale Project

Thanks 03flyer. Looking forward to finishing and flying this one myself! Don’t know your itinerary and apart from the Tesla Museum... the Russian graveyards are the best. Italy, Mediterranean Sea (with stops in Italy, France, Spain), Naples (including Pompeii, Herculaneum and Mt Vesuvius), Croatia, ...

Re: Nike Apache Half-Scale Project

Have you thought about using the main sled as a circuit board to connect everything? Every time I do one of these I think the same thing! I think the outcome would be spectacular :) I do that sort of stuff for a day job, so my inclination to come home and do the same thing is not strong. Here is a ...

Re: Nike Apache Half-Scale Project

Avionics Assembly I already have an avionics set for this rocket, but I am changing the Apache to the regular "skinny" payload bay. This is so I can get some more altitude out of it at Thunda next year :D . This necessitates a new set of electronics to fit into the 3" airframe. First...

Re: Question for L3 flyers

Back in about 2007 I build a Dynastar Orion from Apogee Components: dyna_orion03.jpg Lots of flights on D motors. Followed closely by a few from Sirius Rocketry, and then into HPR :D L3 is not that difficult, if you can research, and think, and work your way up at a rate that is appropriate for the ...

Re: EJECTION CHARGE!!??

How much BP? The right amount to do the job. Ground testing normally confirms the correct amount when using electronic ejection. Since you are BP limited you don't get that option easily. If you take the volume of the parachute compartment and get the numbers for diameter and length in inches (empty...

Re: SpaceX CRS-14 Dragon Mission

Autonomous Flight Termination Safety System is my guess. Used to be AFTS but they snuck an extra S in somewhere. Early versions were FTS (flight termination systems) which relied heavily on the RSO to terminate the flight, based on the data he was fed. The AFTS (or AFTSS) relies on pre-programmed no...

Re: Southern Cross Rocketry - Engine RSE files

If you are just estimating altitude, use one of the other files (Estes or Aerotech) with similar Ns energy and average thrust and you are likely to get a good estimate. Accuracy of this will degrade the more you go towards supersonic.

Re: Complete Newbie - Clusters and Clamps and Control (Oh No!)

I don't know the standing on this for either TRA or AMRS perspective. Someone else can possibly chime in on that. I will comment on the fact that you are guiding the rocket back to a known location. If you have the "known location" too close to your launch location you have likely increase...

Re: Complete Newbie - Clusters and Clamps and Control (Oh No!)

Check out this build for a great cluster ignition method. Sort of a refined version of "flash in the pan" ignition.

Should work great for BP motors.

Re: Complete Newbie - Clusters and Clamps and Control (Oh No!)

Welcome to the forum dmeeze. In relation to guidance you will need to check with the AMRS rules, or get direct clarification on their stance on this, since you are with QRS. In Tripoli Rocketry Association guidance is allowed, as long as it is not controlling the rocket towards a target. I choose to...
