Correct-2 strips of gorilla tape with the motor at the fin root.

I didn't get any pictures of the wiring setup, but since these were just test flights and I was using motor ejection anyway, I...

Flew the first of 2 today in my extended LOC IV. H152 BS for boost with an E12-0 taped to the outside airstarted 2 seconds after a 2 second burn. I used the motor eject for the parachute and blew the...

Yup-Just checked and I have one in each way, so it probably doesn't matter given both seem to be working.

I assembled my second one last night, updated the flash and programmed both of them for a couple test flights this weekend airstarting some small Estes motors. So far it's a pretty cool product that...

Check out Aerotech's Medusa nozzles. I haven't flown any in a while and think they may have been phased out, but they were multi-port and might give you some ideas. They come basically pre-machined...

Good point on the G forces. Now to find that soldering iron...

Just got both of mine in the mail. Going to pick up some IC sockets tomorrow and dig out my soldering iron (if I can find it) and hopefully get them together to test out the airstart functionality...

Performance Hobbies FWFG nose cones can get at least pretty close with some easy mods. This one survived going sideways at M3.15 at 8,500' MSL

Really terrible cell phone picture, but I'm starting to prep "I forget the name of the rocket" for Sunday. I won't be able to make Friday or Saturday so hopefully the weather holds out.

They've still got plenty of time to get a new rocket together and test flown before then.


I'll be there. 5th time, 2nd as a mentor.

Just weighed mine and got 8.9lb including the forward closure, both retaining rings and the nozzle holder

Your setup looks pretty reasonable as long as the parachute won't get stuck in the nose cone and not deploy. It seems pretty unlikely to increase the chances of tangling and despite the name, a short...

Safety Wire

Hobby pyro folks have used units similar to the amazon units for years. I haven't kept up with the forum, but his forum used to have a wealth of information on the conversion of them to systems for...

M3.15 at approximately the equivalent of 8,400' MSL. 4", filled the upper part with foam, the lower part was glassed internally, including the coupler and the joint between the coupler and the nose....

You can fly a K1620 (CTI 1 grain V-max) in a 6xl case with 2 forward closures, one at the top of the case and one at the top of the motor. 3" PVC works as a spacer. Not sure what the mass & mass...

Many states have tenant-landlord laws that are very much in favor of the tenants. I'm not familiar with NH, but you may want to look into it and see if they are legally able to evict you with...

Very true. It was used as an ablative layer on the fin leading edges, so those differences were unlikely to matter too much. If we had a fin back, I'd report back on how it did.

Cheap, yes, free, no. We already had a case as well. There seems to be a lot of focus on the last minute aspect of this. I do not think that that was a contributing factor to the failure, and it's...

I'm interested in investigating the rail button thing a bit more. As far as I know, we're the first ones to use them on something like this. Also agreed on the stress concentration on the forward...

On the nose, yes. On the drogue, no, but that joint never separated.

Team Last Minute Rocketry travelled to Tripoli Las Cruces the weekend of December 29th for a final attempt at CTI’s N5800 Challenge. As our group name implies, we push things to the last minute, and...

For data junkies, that 10% can be a lot, especially when it is affecting half of your product (or at least both of my ravens). I wouldn't imagine it would be that difficult to build a small...

With proper configuration (ie, baro + timer). Accelerometer error on it adds up enough that it can't accurately predict apogee via accelerometer on super high flights. The baro sensor also runs into...

A bit late to the game, but I haven't ordered anything from Wildman in a while.

Get rid of the foam peanuts in the boxes. They're annoying, they get absolutely everywhere when you open up the box...

It was my first Red Glare and I had a great time. I flew my "I forgot the name of the rocket" rocket twice. I built the thing 5-6 years ago and can't remember what I called it back then, hence the...
