V2 Rocket Flying Version

This is the flying scale version of the V2 Rocket previously published as a static model. The tail section now has mounts for the motor tube mounting rings of which you will need to print x2 of. The motor tube is a cardboard BT-50 tube made by Estes <https://estesrockets.com/product/003086-bt-50-body-tube/>

The Nose cone can be printed complete or in two parts for smaller printers.

All parts printed at .20 layer height and 5% infill.

You will also need a Pringles cardboard tube.

You MUST!!!!! add 80 grams of weight into the tip of the nose cone before gluing the parachute plate in place.

Search for YouTube videos on how to make model rocket engine mounts and it will all make sense when you see the construction of the rocket.

You will need to print two of the motor mount rings.

Fabricate the main motor end bulkhead out of thick cardboard and glue in place with thick super glue or Tight Bond wood glue.

The test flight revealed an issue with the heat from the ejection charge shrinking the main body tube making it difficult to refit the nose cone for next flight. To rectify this, I fitted a Pringles cardboard tube to the inside of the main body tube. Print off x3 of the tube spacers and glue them to the inside of the body tube as shown in the mid section diagram photos, 25mm in from each end. A Pringles tube cut to 170mm in length is then glued to the tube spacers inside the main body tube. Push the Pringles tube all the way down to the bottom bulkhead. The pringles tube should be 66.8mm in diameter.  

I tested the rocket using a D-12-3 model rocket motor and it flew perfectly as seen in the maiden flight video. It had a slow scale like take off which was great to see.

The parachute was made from an old shower curtain and is 550mm in diameter with 1meter long strings sewn to the parachute. Strings are then tied to a clip style fishing swivel.

The shock cord is just plain old 8mm elastic, 2 meters long.

The shock cord is attached to the inner cardboard body tube by folding a piece of thin cardboard three times using thick super glue in each and every fold. See template photo.The final fold is then shaped and glued to the inner cardboard Pringles body tube. The other end is tied to the eyelet in the parachute plate. The parachute is also attached to the eyelet in the parachute plate using a clip style fishing swivel.

You can use the motor tube cut guide to squarely cut the BT-50 motor tube.

Total weight of the rocket including the motor came out at 376 grams.

Good luck and please message me if you have any questions.
