My Micro Flying Disk by ijcooper@juno.com

I have been working on getting a Flying Disk type plane down to something under 3oz to fly in really restricted areas and this is my progress todate;

Spec's

  • Power = Astro Firefly 4:1 Planetary Gear and esc System
  • All up weight (RTF) = 2.8 oz (80 grams)
  • Span = 14"
  • Area = 130 sq"
  • Prop = GWS 6X5
  • Battery = 2PX2W 145 mah Lith Poly (Total 290 mah @ 8.4 Volts)
  • Static draw = 1.2 amps on fresh charge

First I have to mention that I have gotten to be a master at adapting nearly any type prop the Astro Firefly Motor Gear Box system & getting it to stay on that little shaft.

I am currently using the Astro Firefly drive in My Micro Flying Disk made in a pretty conventional carbon rod method. Covering is non traditional, as I use USPS printed Tyvek. It was the best combination of nearly indestructible characteristics and relatively light. Plus it did not cost anything and comes with a preprinted design.

I found that 3M 77 spray adhesive bonds Tyvek very well and is easy/good to work with.

Pictures: Note the picture below show the previous setup with a 340mah LP it also flew well, but was .5 oz heavier and a little faster. The Micro Flying Disk now flies comfortably in my obstructed back yard.

Probably my next step will be to make a fragile one out of balsa and some really lite film. like the Reynolds Wrap.  Or if I wise up, Dan's Mini IFO which will probably fly better on my power setup than my home brew design.
