Micron Capacitor-Power Kit
Print version, PDF
These assembly instructions apply to the 10F size capacitor power kit
supplied by Micron R/C. This is available as an option for the Stevens
Aero micro Hawk kit but may be used with other
similar sized models.
The kit contains a 10F 3V 'super capacitor', a 0.22ohm resistor for limiting
the charge current, a prepared Veroboard, a 'UM' charge lead and a motor
lead with 2 pin 1.27mm pitch socket. The completed unit is suitable
for powering many small coreless motors - e.g. the 8.5mm diameter
PKZ3616 or CL-0820-15-9T.
Please check that all components are present in the kit bag and
contact Micron if anything is missing.
Position the Veroboard as shown in the image and pass the positive (long)
and negative (short) capacitor wires through the board as illustrated.
The capacitor has a stripe running down the body to identify the negative
lead; sometimes this stripe also has chevrons along its length.
The negative wire is the one closest to the stripe.
Take care to get this correct as reversing the polarity of the capacitor
will result in its destruction when the battery is attached.
Once you are certain
that the capacitor is inserted correctly, solder its wires to the Veroboard
tracks, ensuring that the capacitor body is pressed firmly against the
board. Snip the capacitor leads close to the solder joint and keep
the pieces you have cut off.
Installation and Use
The completed power module can be friction fit into the microHawk airframe or taped/glued
into other airframes.
The capacitor typically reaches full charge in 12-15 seconds – charging longer than this is
of no benefit.
First flights in any new model should use approx half charge to give a shorter flight for trimming.
To determine half charge count out 6 or 7 seconds and listen to the propeller/motor noise
to decipher the relative amount of power you’ve added to the system by the audible pitch
of the system under power.
