The design expectations are:

Max Thrust: 88.24 N
Average Thrust: 44.61 N

Time of Burn: .551 sec

Four segments of 3/4″ pvc tubing cut to 4.25″ lengths.

A ramming tool was fabricated using a 3/4″ wooden dowel and adding markings at 3.5″ for the bottom clay and at 3/4″ for the top clay.

E45 Ramming Tool

A grinder was used to make a batch of fine clay powder then the clay powder was dampened and rammed into the tubes.

The propellant mixture is 35% sucrose (fuel) and 65% potassium nitrate (oxidizer) by weight.

JB Weld was used to reinforce the clay caps.

Propellant was poured into the tubes and rammed tightly together.

Clay was mixed and rammed into the tubes.

The engines were placed in the storage container.

The Blue Dart Delta II rocketplane was modified to fit the larger E45 engine.

JB weld was used to reinforce the clay nozzle end of the engines.

A 7/32” diameter hollow core was drilled 3.5″ in each of the four E45 engines from the nozzle end through the centre of the propellant.

Now the engines are ready for static tests at Crooked Creek ! If all goes well then we’ll use one to launch the Blue Dart Delta II.

Grass runway 21 in Lindsay was very bumpy so takeoff was from paved runway 31.

Blue Dart Delta II Assembly https://beyondblue.ca/2020/08/blue-dart-delta-ii-assembly/ Sun, 23 Aug 2020 19:41:23 +0000 https://beyondblue.ca/?p=6936 Read More]]> The Blue Dart Delta II is a fiberglass experimental RC rocket plane. It is based on the original Blue Dart Delta all foam rocket plane.

The body tube (BT-80) was glassed with 1-ply of BID cloth and covered with peel ply. Paper templates were made for the delta wings, winglets, vertical stabilizer and ventral fin and then layed out on 3/8″ foam.

The peel ply was removed from the body tube and the glass ends were trimmed and sanded flush with the ends of the tube. A fin tool was used to mark the locations on the body tube where the wings, ventral fin and vertical stabilizer are located.

The rail buttons were located, drilled, and installed.


The BT80 x 24mm Engine Mount was assembled and installed.

The first side of the wings, winglets, vertical stabilizer, and ventral fin were glassed with 1-ply BID cloth (at 45deg to airflow) and covered with peel ply.

Glassed the 2nd side of the rocket parts with 1 layer of BID cloth at 45 degrees and covered with peel ply.

Cutting out the fiberglass delta wings, winglets. vertical stabilizer and the ventral fin. A rocket plane is starting to take shape!

Cut out the elevons then added the horns for the servo rod connections and hinged the elevons in place.

Used 5-min epoxy to tack the winglets to the wings and the vertical stabilizer and the ventral fin to the body tube.

The delta wings attached to the body tube using 5-min epoxy.

Flox was applied on the top surface of the rocket plane where the wings meet the body tube and the winglets meet the wings. Additionally, flox was applied where the vertical stabilizer joins the body tube. The next day, after the flox cured, the rocket plane was turned over and flox applied to all joining surfaces on the bottom side.

Once the flox cured, the flox corners were sanded, dust vacuumed and primer was added to the rocket plane.

The nose cone and vertical stabilizer were painted white then the nose cone removed and the vertical stabilizer covered and blue paint applied to the remainder of the rocket plane.

Now that the rocket plane body is complete, the servo motor control for the elevons is installed, configured, and tested.

The Blue Dart Delta II Experimental Rocket Plane is ready for initial testing.

Cozy Fuselage Repairs https://beyondblue.ca/2020/07/cozy-fuselage-repairs/ Thu, 02 Jul 2020 23:55:45 +0000 https://beyondblue.ca/?p=6902 Read More]]> This Cozy MKIV project arrived recently from Edmonton and consists of many of the main assemblies such as the fuselage, wings, canard, spar, engine mount, canopy, and nose gear.

The project sat idle in a hangar for a number of years after the original builder passed away. The project has some hangar and road rashes needing minor repairs. First up is the fuselage repairs.

The fuselage interior was cleaned up and vacuumed. The right rear electrical channel still had foam in it so that was removed.

The older and loose foam was removed in the areas that were damaged on the top left of the instrument panel and on the left side of bulkhead F28.

New foam and micro was applied to the areas needing repair.

I cut out the bent and delaminated fiberglass and removed the corresponding foam from the front top left of the fuselage.

Foam blocks were placed in the gap and held in place with 5 min epoxy.

The blocks were cut and sanded to shape.

Micro was applied to the foam followed by 2 layers of BID cloth, and peel ply to the interior side of the repair.

There was a hole on the left side of the nose and no ballast compartment. I filled the hole with foam pieces held in place with 5 min epoxy. Next up I will finish shaping the foam, filling in any additional low areas and mark the location where the ballast hatch will be installed.
