Brief:
What? No more 10.5mm motors for your Apogee Micro V2? No problem! See how I built an adapter unit to let my Micro V2 fly on 13mm motors.

Construction:
The major parts include:

• - One completed Apogee Micro V2
• - 1 ¾" of 13mm tubing
• - ¼" of a mini motor casing
• - ¾" of a micro motor casing
• - Balsa fin stock
• - One wood screw (or other nose weight)

Construction is simple. Insert and glue the section of micro motor casing into the section of mini motor casing. In turn, glue this into the 13mm tubing with the mini motor casing flush with the end of the tube. For the fins, I traced the rear contour of the Micro V2 fins and then extended the pattern to make fin extensions that fit below the existing fins and run the length of the 13mm tube. I cut these from 1/16" balsa. When gluing them on, I inserted the motor adapter into the Micro V2 and then used the existing fins to align the new ones. Finally, I had to add some nose weight, so I grabbed a 'surplus' wood screw, and inserted it into the nose cone, through the existing clay. My CG with the booster unit inserted but no motor, is 4 inches from the tip of the nose cone. That much nose weight wasn't required, but I wasn't worried about the loss of performance.

Flight:
I friction fit the extension into the Micro V2 with some masking tape, and did the same for the A10-3 motor. The boost was relatively fast and there was some wobble or coning, I couldn't tell which.

Recovery:
Recovery was via the Micro V2's streamer and was successful.

Summary:
This is an easy way to keep your Micro V2 flying until Tim comes to his senses and resumes production of his micro motors!
