Why You Should Be Excited About Odd’l Rockets’ New BT-20H Body Tubes

It’s hard to get excited about a cardboard tube.  But, when that tube opens up new possibilities for model rocketry, it is newsworthy.

The Odd’l Rockets BT20-H Heavy-walled BT-20 Body Tube

Odd’l Rockets is now producing a thicker-walled, heavier BT-20 body tube, the BT-20H.  The BT-20H is now available from JonRocket.com.

Here are reasons why you should be excited about the new BT20-H body tube.

The BT-20H is thicker and more durable than a standard BT-20.  The inside diameter of the BT-20H is the same as the inside diameter of a standard BT-20 body tube, 0.710 inches (just a hair over 18mm). But, the wall of the BT-20H is about 60% thicker – 0.021 inches thick versus 0.013 inches for a plain BT-20.  This extra thickness makes the tube much stronger.

The BT-20H is perfect for 18mm motor mounts.  A rocket’s motor mount can take some abuse as you insert and remove motors and during flight from the thrust of the motor and the ejection charge, so the extra strength of the BT-20H makes it a good choice in motor mounts for standard size motors. The inside diameter of the BT-20H is the same as the BT-20, so you can use a standard 18mm thrust ring. Standard engine hooks also work and there’s less chance of the tube tearing in the slot you make for the top of the hook. A more robust engine mount made with a BT-20H is perfect for use with the powerful 18mm composite D motors from Quest.

You can use standard centering rings. Even though the outside diameter of the BT-20H is larger than the BT-20’s, you can still use standard BT-20 centering rings.  The inside of a standard centering ring can easily be sanded (or peeled) to fit the slightly larger diameter of the BT-20H.

You can use standard nose cones. Standard BT-20 nose cones fit the BT-20H tubes. Because the BT-20H is slightly larger in diameter than a BT-20, there might be a small lip around the end of the body tube.

The thicker BT-20H provides better heat resistance than thinner BT-20 tubes.  Being more resistant to the effects of the motor’s ejection charge makes the BT-20H a better choice for motor tubes and, especially, for stuffer tubes.

BT-20Hs are easier to work with. Being thicker and more durable makes the BT-20Hs easier to cut and less likely to be crushed during construction of a rocket.

The BT-20Hs open up new possibilities. A stronger body tube allows for more complex designs such as rockets with strap-on boosters or extra-long “super-rocs.”

The BT-20H extra-strength body tube is now available from JonRocket.com.

Jonrocket.com is Attending NARCON 2018

NARCON 2018 will be held February 23 through 25, 2018, in Houston, Texas.  JonRocket.com will be there as a vendor.

NARCON is the National Association of Rocketry’s annual convention.  The three-day event features guest speakers, technical presentations, and a banquet on Saturday night.  A special feature for the 2018 convention is the option to tour Space Center Houston with rocketry enthusiast and aerospace historiography, John Pursley. Pursley will lead a very special “walk-around” tour of the Saturn V on display at the Johnson Space Center, highlighting elements of the multi-year conservation project in which he participated.

Bunnell Blast is a two-day TRA Research launch.  Two sets of launch pads, low-power and high-power, will be in operation on Saturday from about 10:00 am to sundown and on Sunday from about 10:00 am to 3:00 pm.

Georgia Rockets in the Sky (GRITS) is a two-day launch that has moved to Thanksgiving weekend this year.  Taking place in rural Georgia, GRITS offers a large launch site allow very high-altitude flights of high-power rockets.  But, the launch is also model rocket friendly.

Both of these launches are expected to attract flyers from all over the Southeast.

 

JonRocket.com Supports Space Week Activities in Brevard County

JonRocket.com has made a donation to the National Space Club Florida Committee to help support their Space Week educational outreach in Brevard County along Florida’s Space Coast.

Space Week actually lasts several weeks.  During this time, every sixth grader in the county’s public schools is able to spend a day at Kennedy Space Center and engage in a number of space-related activities.

In 2016, more than 6500 students participated in the Space Week program.

For more information, please visit the NSCFL website at https://www.nscfl.org/spaceweek.

 

Odd’l Rockets F-16

In the late 1970s, Centuri released a line of fighter jet inspired model rocket kits including the F-16 Fighter.  Drawing on Centuri’s classic design, Odd’l Rockets has released its own F-16 kit.

The Odd’l Rockets F-16 features laser-cut parts, waterslide decals, a stronger body tube, and excellent instructions.  But, it is the vacuum formed plastic canopy that sets the F-16 apart from other kits.

The F-16 is now available at jonrocket.com.

NEFAR Half-Blast – April 22 and 23, 2017

We’ll be at the NEFAR launch this weekend, April 22 and 23, in Bunnell, Florida. The “Half-Blast” is a two-day TRA Research Launch. Normally NEFAR’s launches are held the second Saturday of each month. Due to conflicts with other events, however, this month’s launch date has been moved.

We will have a selection of rocket kits as well as supplies and accessories including motors. In addition to Estes and Aerotech model rocket motors, we have some of Aerotech’s high-power DMS (single-use) motors for sale.

 

 

(Still) Moving …

JonRocket.com Trailer

Moving is exciting.  Moving is challenging. Moving is a lot of work And, as we are demonstrating, moving is time-consuming!

We are still working hard to get JonRocket.com back on line. We have all of our inventory in our new office. Most of it is unpacked and sorted. We still have some things to unpack.  

We are also continuing to move furniture and fixtures into the office. Almost all of the furniture and fixtures are new (or, at least, new to us). Some arrived in big cartons with assembly instructions spelled out in hieroglyphics. 

The office now has internet service and we are starting to set up the computers and printers that we use to process orders.

We started to “flip the switch” to enable the online store this weekend (March 4-5).  But, realized that we weren’t quite ready and trying to process orders while still setting up the office was not really a good idea. Bracha and I apologize for how long it is taking, but we have decided to continue to take our time and do things right.

We are currently in the process of moving JonRocket.com to a new location.

We will have more room to stock a larger selection of rocketry kits, supplies, accessories, and motors.

During the move, we are closing our online store.  Once the move is completed, we’ll be back!

We understand that this is not the best time, but a combination of circumstances has forced us to close our store temporarily during the move. We had hoped to be back in business in time to support your holiday shopping, but the move is taking longer than expected.

We are now estimating that our store will be back online around the end of February.

Thanks to every one of our customers and friends for your support since we started running JonRocket.com over seven years ago.  We look forward to serving the rocketry community for many years to come!

Orlando Sentinel Article About Our Local Launch

sentinel-253x300We try to attend each of ROCK’s monthly launches in Oviedo, Florida. At this month’s launch was a reporter, Caitlin Dineen, from the Orlando Sentinel newspaper. She interviewed several of the launch participants including our club’s president, Brian Coyle.

Jordan Krumbine, the Sentinel photographer, took photos of people prepping rockets for flight, launching rockets, and watching the flights.  Carl Campbell, of Real Space Rockets is featured in one of the photographs.

Later the same day, Dineen’s artice, titled “Rocket Enthusiasts Find Great Heights,”  appeared in the Space News section of the Sentinel’s web site. The article includes a gallery of the photographs taken by Krumbine.
