SQ8 Hatcam Notes

 Got an SQ8 camera to try as a hatcam.  It has a nice clip system.  I made an adapter out of instamorph,  Even if the camera turns out to be a dud, I'm super impressed with how well the instamorph holds on to the brim of the hat.

I'll try it out "for real" soon and report back on image quality, etc. So far not too bad for $20.

I think I need to get a faster memory card though.  1080p carries about 15 FPS.

Some stats: 720p, about 6Mbps, 29.79 FPS; 1080p, a bit less than 15FPS.

The way I've got it mounted now holds the camera upside down.  Here's the incantation to flip the image and convert to h.264.  The duplicate transpose items aren't a type.

    ffmpeg -i PICT0002.AVI -vf transpose=2,transpose=2

April 2016 Shopping List

Here's what you need to get started.

Basic Idea:

  • Transmitter and Receiver
  • Airplane Electronics
  • Body Parts
Nice Starter Plane:
  • EZ-Fly

Transmitter and Receiver.

Get these from Aloft Hobbies, one of the best vendors on the net!

(to be continued)

Airplane Body

Here's the raw materials for the E-Fly Body.  For each body, you will need 3 sheets of foam, 1 carbon tube, and two pieces of steel wire.  I think severlthe shipping won't go

You can also buy the foam pieces pre-cut:

Power System


Here's some other stuff you will need

Mini Drake Flying Boat

Got this from Hobby King... comes in a flat pack, gonna have to really glue it up old school!

HK Page
RCG Thread

Based on the original 1951 Drake.

Recommended bits:
    AeroLite or MicroLite
    Micro Control Horns
    Linkage Connectors
    1811-2900 Motor
    MultiStar 10A ESC (pre-BL Heli) (6A would be fine too)

Random RCG notes:

  • use two (2) #16 rubber bands to hold my wing on.
  • The CG per instructions is on the main spar for the wing. It should balance there when placed on your fingertips. 
  • Construction Notes
