Hot Rod Rockets sells kits with a square chute. They're quite nice, actually.

I would say that the square design fails in that you get significantly less drag per unit area of material. It's all...

Looks Awesome! I love the offset motor tubes/fins.

It's always better when it looks like the rocket wont fly... and then it does.

Looks great! I love your fin alignment method, with the spent motor glued to the sheet. Nice!

I agree, looks very far from redneck. It's a beauty though!

Last BT-55 rocket I made was 2-stage,...

Thank you! I've been trying to compile something like this for myself, but this works way better!

Funny you mention this, this why I was so interested in this! Except with a 54mm motor...

Where did you find such a glorious piece of hardware? I must have one. Or two. Or three.

Any possibility of a 3.3v SMD regulator board, along with the extra pyro outputs board? I love the fact the Eggtimer uses seperate batteries, but I know it's hard to fit two batteries in a small...

Is the storage unit for just storing things? Or are you using it as your rocket workshop? (Can you even do that?)

That's one big Nike!

I'm right with you. It is very penguin-like

I would be more than happy to share the scripts. It is indeed an extremely powerful system, but very complex. Matlab is vouch more user friendly, but I can't argue with the free price. One of my...

Way cool!!!

I know what I'm doing with my tender dezzender now! Glad to see people pushing the limits.

Also, great liftoff shot.

Welcome to the forums! I have a few answers and questions for you...

First of all, that's a huge sugar rocket! Where exactly do you fire these off? Are you part of NAR or Tripoli? HPR certs? I...

I usually use the "scatter" plots in excel. They produce more scientific-looking graphs. I always have trouble using the line ones, they never turn out like I really want them to.

The other...

:lol: This made me laugh quite loudly. I think the title of the thread already had me in a laughing mood haha

Anyway, Stiffys are great! They make AV-bay making a dream. Just make the bulkheads...

I saw some at Lowes last time I looked, surprisingly. They don't look as if they swivel easily though.

I have used around 20 foot sections as tracking in smaller rockets. It rolls up tightly, and if you pack wadding well around it it rolls out completely. You simply can not miss 20 feet of caution...

Wait.... You taped E12s to the side of the rocket?

Any information on your battery and wiring setup? Picture of the AV bay internals?

Also, are the flight event spikes put in by the Eggtimer,...

Throw a Mylar streamer in one of the side tubes, so that it can be pulled out when the booster motor fires.

Noticed that you put a terminal block on your AV bay endcap. Are the holes in the ends of e bay designed for running ematch leads through, directly to the altimeter? Or more for this sort of thing....

Other option is epoxying in an aircraft cable leader. Get a crimp and make a loop, and make a notch big enough so that the crimp remains behind the centering ring while the loop is above it. This is...

I use the "speaker connectors" that you speak of for all my rocket needs. They work wonderfully. Over in EE land we call them "binding posts" or "banana plugs". All the same thing. I get mine at...

Someone correct me if I'm wrong, but they look like the stickershock decals.

You know... I have a bunch of little RC car antenna tubes left over from my Nitro Car days.... That would work perfectly!

I remember the Rx bottle failure last season. In fact, it was this event...

I800 vmax in blue tube with an Acme fin can. Kind of cheating, blue tube is crazy strong.

My EZI-65 has taken at least 300 or so, dont recall the motor.

I think its more speed and fin flutter...

I wonder if you could pre-sew a single piece of thread through a kevlar shock cord. The thread would snap, absorbing energy, and these loops would snap until there was not enough momentum to break...

I want it to fit in a 54mm body tube, with a little room to spare. I will make dedicated bay for anything smaller.

I have the wire antenna version. I guess it wont hurt if iIjust tack on a new...

The Cable cutter for releasing the AV-bay is probably the only thing I would change. Does his motor mount come down by itself on its own parachute? Or is it attached to the drouge? He had alot of...

Hello all,

I recently purchased a BRB 70cm Transmitter, and I want an easy, reliable way to transfer it between all of my rockets. I know that a dedicated bay would be better, but I would rather...

Does this have a 29 or 38mm motor tube?

Looking good! I have to re-build my mailer rocket.

You know... I never did this and I dont know why. I run into this problem so frequently, and i just end up tying the rope to the eybolt. This is why I love this forum!
