Belly mount

Recommended Posts

Here's a few pictures of my belly mount setup.

The first two are the 'usual' setup. The camera is bolted to a small aluminum plate; the plate is held on by a type-8 strap and a lightweight friction adapter (like the one on wide cheststraps.) The black box is a circuit that fires the camera once every second.

The third picture is a legmount I use for canopy shots. Since the snag hazard is rather high I only use this for solo hop and pops. There are a few commercial belly mounts that look something like this; I tend to avoid those for normal RW.

Nice pictures.

In the first one it looks like you have a light coming out of your head or a megaphone so you can hear better :P

Bill,

Care to share the circuit design? I could figure it out but it's been a long time since I took circuit design. I once designed one that waited a variable small amount of time, then fired 1, 2, or 3 shots. This was armed by a grip on a handle on the strut of a 182. Then fired by the student releasing the handle. Fired a camera mounted at the end of the strut.

Any, care to share?

I've seen some of your belly mount pictures and they look great. Maybe this is what I need. I've had so much neck trouble that I have a lot of trouble jumping a conventional camera helmet, with a couple cameras on it. Then again my hard opening canopy doesn't help any. Maybe you should patent some of that and market it. I'm interested.....Steve1

>Care to share the circuit design?

It is a PIC16F88 processor with some software. To run a camera via Sony's LANC connector, you need to speak to the camera in this bizarre serial protocol, and 'fool' the camera into thinking your gadget is a real Sony remote shutter release. Only other parts are a zener diode (to cut down voltage) and a few resistors/capacitors.

Once I have it working 100% I will try to build a few and send em out to people. It's really cheap (a few bucks in parts.)

>- Miniforce rings on your Icon?

Because we swap canopies/bags/PC's quite often. I believe the Miniforce risers are currently on the Pilot 150, which is my wingsuit canopy and the canopy I am taking to Thailand. (I don't really want to manuever the 108 through that many people!)

>What size canopies or wing-loadings are World Team organizers recommending?

I _think_ in 2004 it was 1.25 to 1.75. The canopy I end up using will actually depend on where I'm opening. If I end up pulling high or in the middle, it will probably be the Pilot 150, loaded about 1.3 to 1 - that way I can out-float most people and land with the cameramen. If I end up in a low pulling wave, I may go with a smaller Pilot so I can get down more quickly.

Given where I was last year, though, it is likely I'll be pulling higher rather than lower.
