I recently acquired a thin-wall fiberglass 2.6" tomach with the 54mm motor mount, and I plan to push it pretty hard. Unfortunately it comes with 1/16" thick G10 fins, which in my opinion would likely flutter right off the rocket around mach 1.5. Considering that this rocket can do nearly mach...

My level three flight went perfectly! My flight was on a Loki M1650, which pushed this beast to 7030 ft with a max speed of 659 ft/s Onboard video: https://youtu.be/kYoej2Nj6vc Enjoy! Thanks for all the help and advice!

I thought about a roll pattern on the white tube, but I'm not quite sure...:)

I realized I haven't updated this in a while, so here goes! I had to re-prime after it got drug through the field at Bayboro. I enlisted my friends help and HVLP gun for the orange and clearcoat, but was able to do the white and black with rattle cans. Pics for your enjoyment and me for...

I find that the number depends entirely on material. Phenolic only seems to last 3-5 flights, bluetube 6-15, and fiberglass a generally unlimited amount. This is how I justify the $$$ I spend on fiberglass:)

The bluetube rocket I flew the other day (made with 2.0) had significant shrinking issues when it got wet. It was sealed inside and out with sanding sealer and had a good paint job over that. We could not get it to separate at the couplers no matter what we tried. I will agree that bluetube...

My L2 was bluetube, it's good stuff, but it absolutely pales in comparison to fiberglass. If the rocket happens to get wet, bluetube will become useless, fiberglass is immune. (Two water landings last Saturday, one BT, one FG....) If I can help it, I really try to avoid anything other than...

Thanks! I'm planning on September 23rd in Bayboro.

A few more pictures I forgot to attach and can't figure out how to edit in oriented correctly....

It's been a while since I've updated this, and I have a lot to update! My shakedown flight on a research L went well! It was a little under-powered, but that allowed me to see the whole flight and how the recovery system lines everything up on descent. Max altitude was 1700ft. The deployment...

The bag is attached to the apex of the main chute and the pilot is attached to the bag. I'll post a picture of the whole thing drug out when I get a chance...

The shroud lines of the main parachute (the quicklink by the bag) will attach directly to the main harness.

I have decided to use the integrated method as shown in the diagram above. I ended up with a fruitychutes deployment bag and a top flight 36" parachute as my pilot. Does anybody see any problem with this setup? I am doing a shakedown flight this weekend and will ask my TAPs as well.

After reading through that thread, I have a few questions: 1. Is there any reason to attach the bag and pilot chute to the apex of the main parachute as shown in the integrated configuration below instead of the method of attaching the bag and pilot to a third loop on the harness as was shown...

I've finished priming: Now I have to decide on a paint scheme.... But it won't get painted until I'm out for the summer I'm afraid... I'm still a bit confused on how I should rig a deployment bag. I've found plenty of resources showing how to pack the chute in the bag, but very few showing...

Thanks! I will fly the first time (shakedown flight) with just primer, but when I get around to the cert flight it will be painted. Once I decide on a design.... Ejection testing went well today, I will be using 4.5 grams for each primary and 6 for the backups. Is there any rule of thumb for...

Update time! I got my main chute, a 168" spherachute: I plan to use a deployment bag (for the first time) after seeing how huge this thing is. I ordered the xxl size that apogee had, but am not sure how to choose a pilot chute. Any input? I also drilled and tapped my shear pin holes and...

I got them from Chris short: https://www.csrocketry.com/electronics/missleworks/6-32-screw-switch.html About charge size, It seems that 6 grams is widely agreed upon, but that anything from 4 grams up will work fairly reliably. My backup charges will never be anything less than 6 grams...

I was planning on using 6g as my backup charges. I'm going to start ejection testing at 4.5g. I have decided on 4 4-40 pins in the nosecone and 2 4-40 pins in the drogue. The latter is still slightly up in the air, but I like the large margin 4-40 pins give. I will drill 2 1/8" holes on...

Huh, never thought of that. I have a metric butt-ton of 1/2" Kapton tape, I'll have to give it a try...
