Cox International Engines Flying on "The Board of Engines"

[Kim]

The recent discussions of Cox International's "Specialty Engines" caused me to flash-back to an almost ten year-old video of my 3M B.O.T. cruising above the hill, dragged along by a colorful assortment of Bernie's Castor Slingers.

These were "somewhat de-tuned" with extra gaskets and (I think) 6x3 props to settle down the little monsters, and make them easier to start.

I was quickly losing light as the day wound down, but I still like the video (and audio!) captured that evening.

I've also got to say that any and all of my dealings with Cox International have gone extremely well with Bernie and also Matt of EXMODEL Engines...with over-the-top, fast responses for any concerns I might have had in the 12+ years of dealing with these great guys.

Hey Eric,
I just used the tried and true methods of "Kentucky Windage" or "That Looks About Right" to set up the GoPro.

Using it's wide-angle setting, I just rubberbanded the camera to the top of its servo, which was plugged into a channel that let me use a dial switch on my transmitter.

With the dial turned all the way to the left, I knew it was getting the nose, engines, and whole aft section of the B.O.T (confirmed it by shooting some test footage).  I just guessed at the rest, panning back and forth, until the landing approach, when I knew I wanted it turned full-forward (full right on the dial).

Like a lot of stuff, it gets easier to make a good guess the more you do it.

Thanks Kim , would take some practice for sure

Yeah, a bit...but even the footage that isn't "perfect" can still be some pretty good stuff. The biggest challenge (which I forgot to mention) is getting as little vibration as possible to the camera.
Again, some practice can help, and I tried foam padding and also discovered that the length of the selfie stick can really help.

Looks like the "Blue Bullet" gave out last Kim, left wing. Induced yaw? Little corrective rudder maybe?

Glad to see some of these being used. Seems in the past you have ran a pair of Space Bugs too, and a couple of Gilberts. Experimenter in chief.
