Sauvie plane video

pdxmonkeyboy · Thu Apr 03, 08 3:49 pm **Sauvie plane video**

ok, so I shot the vid through the prop..which presents problems. Then when I uploaded it to u-tube...ughh the quality looks awefull.

mounted above the prop i think I can get some cool aerial video of us kiting. It would be cool to follow someone at water level.

anywho..

wicked cool! Damn, it was glassy that day. i like the barrell roll and the landing. It'd be really crazy with a bunch of kites in the vid.

I am the other guy not flyin in the vid. Monkey we gotta get that thing dialed, I can throw some loot if we can get some cool vids

is it an electric plane? I'm guessing those bars are from EM interference
.

but cool none the less....

hmmm, maybe it is from the interference. It's a brushless electric motor. They seemed to look different at different speeds so I thought that was what it was.

Cool Stuff! Ween ROX!!!!!!!!!!!!!

Nice PDX Monkeyboy! RC modeler meets the kiteboarder. What crazy interference the motor/prop caused! Could you move the camera further away from the motor to reduce the effect?

Thats crazy badass - you'll work out the kinks - back in the day that was what the Horizontal Hold button dialed in.

yeah, I'm going to build a little tower to hold the camera above the prop. I need to overprop the plane so it has more power. It will be a little hairball when its windy put I would think that with the flaps down I could slow way down and follow someone on the water.

The video looks much better than what shows on u-tube.

Good stuff! Thumb's Up

Pretty sure that's not interference. You'd see it when the prop wasn't turning if it was (so long as your radio is on), but I've seen it on nitro planes aswell which rules out the electric motor. I figure it just has to do with the strobing effect of light passing through the prop and the refresh rate of the cams shutter. The cam tower should fix it.

What size plane is that? And what prop are you running?

cam tower and some more horse power get it dialed it will rule

Its a smaller electric plane, the wing span is about 40". That was a 10x7 prop although that brushless motor can swing a 12x8 without drawing too many amps and frying everything. It could be interference though as when the motor is off..there is no current flowing. It's a brushless motor so it moves by generating a large electric field around the motor stator--a big magnet (as apposed to a normal electric motor which charges the stator which is surrounded by magnets).

I am more inclined to think interference as the camera was mounted on top so the prop wash should have shown up as left to right bars, not up and down. How would I protect the camera from elec. interference?

Maybe, but before you try to eliminate the EMI, I'd see how it does when not shooting through the prop... because, like I've said, I've seen nitro planes do it (and only when the prop is spinning).

If it is indeed interference, I'm not really sure how you're going to get it completely eliminated. On our built Civics we have to use high power ignition systems that are prone to a ton of EMI if you don't watch your wiring. For this reason, we keep the ignition wiring as far away from the actual computer wiring as possible (you'd have to do the same) and also cross at 90 degrees wherever they do come close. The main thing that helps us though is shielded wiring. So I'd think this would benefit you too, except for the fact that there's no where to ground on your plane!

Haven't broken in my O.S .32SX on my nitro converted Extra 300, so I'm tempted to do it later today while shooting a cam through the prop just to see what happens...

maybe instead of a tower, you could just point the camera in reverse. Or to the right or left?
that might make for less drag, and the footage would still be ok, might even be cool if left or right for fly-bys...

Not mocking your set-up PDXMB ; It's way bad!

(Bergen also has a "sky-park" gizmo so you can basically park your chopper anywhere in the sky, then pick up the camera controls!)
