Phantom 4000 Build

[Texas Rocketman]

I just completed building an old North Coast Rocketry Phantom 4000. I've had the kit laying around for over 10 years and decided to put it together. I utilize a 29mm Aerotech RMS 29/40-120 G64-10W reloadable motor which fits perfectly in the original 28.5mm engine tube. Other than the engine modification, it's pretty much original. This is an easy rocket to build. Can't wait to see how it performs on Aerotech engine. I've attached a pic of the completed rocket. Who says you can't have fun with the old stuff.

Nice looking rocket!

Before flying with that motor, check out the flight report below regarding delay time.

I have a huge soft spot in my heart for these! Love 'em, but check your mass, sim it and drill the delay! Mostly 3-5 secs.for the smaller motors.

Lol that's why I got a big chute on it. I want it to come down fast but not so fast as to damage the rocket. I want it to fall for awhile. I don't like chasing them. Too old for that. I built it pretty sturdy just in case it does take a smack. I built rockets before and launched them without chutes or streamers and had them repeatedly land safely. Down here in South Texas, the wind is slways blowing so you want your rockets to come down as fast as safely possible or else you're going to have a nice ride in your car chasing down your rocket.

Wow! I bitch about a mile walk and you guys use your cars? Everything's big in Texas!
(didja hear about the old oil baron that had the windshield in his Rolls ground to his prescription??)

Lol, with the wind....you need a car. It's nothing to chase a rocket down 5 miles or so if your chute pops at 1500 + altitude. No walking or running to it.lol

Hard core~! Very jealous...can't (would like to) imagine rocket recovery and then stepping back into an air-conditioned car-what luxury!! I'm afraid with wind like that-I'd be setting some very low altitude records.....

[Texas Rocketman]

Lol.....95 degree days, wind is always blowing (except for early in the morning), semi upper desert arid conditions.......definitely need a car and some AC. what ya do is set up your rocket on the pad, hook your launch controller to your power outlet inside the truck, fire your rocket off, then hop in the truck and chase it down if ya have to. The object down here is get it back on the ground as fast as possible to prevent chasing them down too far. Streamers work great. Big chutes and long delay ejection engine combinations work pretty well, and short delay ejection/small chute combinations work good too. When using a chute, a little experimentation has to be used to get it right and like I want it. Big rockets and low altitudes, i like long ejection delays and big chutes. In general, low altitude small rockets, I like short delays and small chutes, streamers or no recovery devices at all. High altitude rockets (both large and small), I prefer long delays and small chutes.
