Odd'l Rockets Heavy Wall BT-20H Body Tubes Now Available!

Over the years, I've grown to hate BT-20 body tubes.
The first time I tried to remove a friction fit engine from an Estes Beta, the tube was bent and the rocket unusable.

Now available from
To see the listing, CLICK HERE

On the left is a Estes BT-20, on the right the Odd'l BT-20H tube.
Standard Estes BT-20 style tubing is thin walled (.013") and prone to buckling and bends. Thin wall tubes can’t insulate against the heat of ejection charges. Paint above the engine mount area can blister.

This new tubing has the same wall thickness (.021") as a BT-55 or BT-60 tube.
The inside diameter is the same as a BT-20 tube. (.710")
Thicker wall tubing is less likely to shrink or “coke bottle” when a glue fillet dries.
Standard engine blocks (5/20 rings) will fit as an engine block.
Existing centering rings can be easily peeled or sanded to fit the slightly wider outside diameter.

  • Engine mounts - Perfect for the new C and D Quest Q-Jet engines.
  • Ejection Stuffer Tubes - Stronger when exposed to ejection charges. Longer life, more flights.
  • Strap-On Boosters - Less damage on landing under streamer recovery.
  • NAR Superroc Competition - Stronger tubes equal longer length designs.
  • Sport Models - Stronger as a main air frame tube. More success for school, Scout, 4H and general sport rocket projects.
The yellow plastic nose cones from Apogee are a great fit for the thicker wall tubes. These nose cones have a wider shoulder than standard nose cones. To see them, CLICK HERE

NARAM 60 Sunday, August 5, Manufacturer's Forum

I participated in the Manufacturer's forum on Sunday night with new products from Odd'l Rockets.
On the right is the new BT-20H, heavy walled BT-20 tubing. It has the same wall thickness as a BT-55 or BT-60.
Imagine the applications - Stronger stuffer tubes, strap on boosters, Super-roc competitions and general sport flying with longer life models!

I have never been a fan of the BT-20 style tubing ever since I crimped the BT-20 on my Estes Beta trying to remove a friction fit engine.
This stronger tubing will better insulate a hot engine and won't shrink up when the white glue dries! A perfect fit with the Apogee plastic (Starlight) nose cones.

Here's the new engine mount incorporating the BT-20H HEAVY WALL TUBE. Stronger for general use and great for the new, more powerful Q-Jet composites.

These Odd'l Rockets engine mounts have a 3" long SPRING STEEL engine hook. That extra 1/4" length hook allows you to glue the engine block in under the upper bend of the engine hook.

The REPLACEABLE KEVLAR mount ties the cord underneath the lower centering ring. Pull it out, check the condition of the line and replace if needed.

I was given a new Quest C12-6 Q-Jet engine for testing (Shown above). I went back to the hotel to get the products together and test the fit of the engine. The newer, slightly smaller diameter Q-Jets are a perfect fit with the labels on!

My third product unveil was a long time coming.
The Odd'l Rockets FIN TOOL will finally be sold after I return from NARAM. Many were interested in a demonstration after I was meeting participants at the front of the hall. These will probably show up on the Odd'l vendors websites in September.
