I'm considering building a KAP rig but am hesitant bc the only
experience with RC i have was a toysRus car i had when I was 9. I
didn't want to bump this really old post (http://groups.google.com/
group/rec.models.rc.air/browse_thread/thread/74395851e4d3187e/
9ca0b9c63bb9ff1f?lnk=gst&q=KAP#9ca0b9c63bb9ff1f) so I started a new
one. Also I wanted to mention here that Chris Benton's KAP site which
is linked from a few places in this ggroup, showcases a rig which is
quickly becoming a design template for my build. (KAP Rig No. 4
specifically. I'm building around a powershot too so hopefully I'll be
able to borrow quite a bit. Here's the page to which i'm referring
http://arch.ced.berkeley.edu/kap/equip/kaprig4.html)

Okay. I'm confident enough in my design/fabrication abilities to build
the rig. But as a RC n00b, I can't justify quadrupling the budget to
remote control the pant/tilt/shoot operation when a timing circuit can
accomplish the shooting part for a just a few bucks.

If I understand correctly, I need a TX, RX, power supply for both, 3
servos, and the right connecting wires. (I've seen this advertised as
an RC System on net.) I have not seen this for under about $120.00
though. Why then have I seen some "ready-to-fly" beginner RC planes
with all that stuff (and a model) for half the money?

Basically if I can get a ball-park for the most modest RC equip. to
accomplish this task, at least then I'd be able to make an informed
decision whether or not to pursue project further. I'm fresh out of
college so budget is key so that I can keep food in the kitchen.
Thanks in advance.

Lighter-duty stuff; economy of scale.

Where do you live? You could try to make friends with
an RC club. Folks often have old systems that would
work fine for KAP that they might donate to you for
free or an 1/2 or 1/3 the cost of buying new.

I think you not only want the RC control but a video
downlink, too, for real time feedback on where your
camera is pointing. You'll only have to run your
kite up and down a few times before you realize that
random results aren't that much fun. (I'm just
guessing.)

Here's my aerial photography:

I've got some ancient links there. I haven't
checked them in years ...
