The title says it all. I built a scaled down LOC Ultimate and flew it on 3 F23 motors. Good flight to 1647'. However, on recovery the unused motor tubes had been cooked and are unusable. They were BT-20. Apogee was selling this size but has no stock. Don Ball (not a TRF member) got some and I...

Found this on Youtube More on the construction This is a multi part set of videos. You can scroll down the listing on the right and watch only the parts you want to see.

https://www.cnn.com/2020/03/09/opinions/mueller-report-barr-justice-department-honig/index.html This is the same judge that was over the NAR/Tripoli lawsuit where he ruled that APCP motors were NOT explosives. ATFE had to take APCP motors off the explosives list and we didn't have to get LEUP...

I'm considering purchasing a lot of G12 tubing sized for 18 mm motors. .625" ID, .703 OD, both +-.005". If I order, it would be this week. Pricing would be $20 to $25 per 60" length, shipping extra (whatever Parcel Post charges). These are not for sale yet.

I'm working on a project to build a rocket with which I can adjust the altitude by varying the drag. Highest would be a straight tube fin. To reduce altitude, I am using plates attached to couplers that fit into the tube fins. The eventual plan is to build a 7.5" version light enough to fly on a...

The 1/4" TN I ordered came in today, thickness is .040" (1mm). I got it from https://www.snowshoe.com/

The latest National Geographic (Sept 2018) came today and it has a photo article about the Balls launch. Title is "Rockets For Regular Folks" (They don't mention the name 'Balls'.)

For the SC Freedom launch, I built a couple of 4 stage rack rockets using Estes F15 motors. Quick RockSim design

For the last 19 years, this has been my rolling range box... However, 2 weeks ago I hit a deer and being 19 years old, the insurance company said it wasn't worth enough to repair. Although it doesn't look too damaged, repairs would be almost $4000 so they totaled it.:( I had to replace it...

I've tried several times to access my YouTube channel but I can't log on. The log on box brings up my email address but when I click on Next, the enter password box only appears for about a second then reverts to the email box. Selecting the password for a new entry causes immediate reversion to...

I found where Kari, Grant, and Tori (from Mythbusters) have been up to. This is an original Netflix project.

This is a quick build thread on the rack rockets I've been flying. This one is a 3 stage using Estes F15 motors. The motors are 4.5" long and I use 5/8" masking tape for a thrust ring on the top motor so the rack needs to be 9-5/8" long. The rails and supports are basswood, fins are...

I have some vacation that I need to use by mid June. I'm considering taking a weekend off and attending a launch. I'm willing to travel up to 1000 miles (each way). This covers most of the eastern 1/2 of the country. Who's holding a launch in the next few weeks and where? To help decide...

On Mythbusters today they revisited the original JATO car. This time they used a LOT more power. It looks like 5 6" P motors. Does anyone know what motors were used? BTW, the car DID fly, just not stable :)

I've just started construction of a bigger Deuce upscale. Body diameter is 9", 99" long. Motors are 98 mm with max length 4 grain. I've reduced the cant angle to 12.3 deg to accommodate the 4 grain motors. The fins are huge! This shows the motor mount, both 12.3 and 15 deg cant. Finally, a...

I'm considering replacing a section of Blue Tube with performance Rocketry/Rocketry Warehouse with 7.5" fiberglass. What are the actual ID and OD and how well do PML nose cones fit? Blue Tube has poor dimensional stability and zipper resistance.

I was in Hobby Lobby last Saturday looking for basswood and balsa. I checked to see if they had E12's - nope:( I did see on the shelf and bought it with a 40% off coupon. First, discard the motor tube and centering rings. Roll a new MMt from paper tape with a wire loop for shock cord...

Our monthly launch at Orangeburg was hosted by the NAR section, ROSCO. Saturday was a good day for flying, comfortable with scattered clouds and light wind. On Sunday, we had to close the range about 12:30 as heavy weather rolled in. On board the Deuce, J250 Skidmarks: QLrhu1fiz6E View from...

The title says it all, airframe, couplers, nose cone, bulkheads. Directly from Performance Hobbies is NOT an option :kill:

Attached is a Raven file for a recent flight. Can you guess what it flew on? Motor(s) are certified. The flight was nominal and nearly straight up.
