Dear Martin

 

Thank you once again.

It all looks a bit more possible now.

 

One thing I would like some help with is the video transmitter's wire dipole aerial.

Could you direct me to a site/source to build one similar to the one shown on your website.

I have the heavier small quarter dipole whip aerials but they seem a little heavy

for this type of installation.

 

Regards

for the Twinstar 1 we put the camera + servos on a small wooden board at
the front of the aircraft:

The Glotzer had it mounted at the cg under the fuselage/wing:

The software configuration depends on the way you mount the servos, that
means the orientation of the axis as well as which servo is fixed to the
aircraft and which is moved (by the first servo). The code in the cvs
allows to automatically move (follow a waypoint) a one axis pitch or
roll camera as well as a two axis yaw-fixed-then-pitch (see above
pictures) camera.

It seems a pan/tilt mechanism was never put in a Funjet, but installing
a camera should be aircraft independent. For protecting the camera
mechanism during landing we had put some music wire under the Glotzer.
