First video ever I think I've captured outside our garden! :)

Much wind, no proper sensor mounting (too low weight of sensor board vs. frame as discussed), thus making PID's untunable. All my next flying things will have more weight distributed to the sensor board plate is the idea. And more motors!

Anyhow, yeah, besides the oscillations, I'm happy with the actual video quality:

About safety: I had a lookout buddy with me. Although, I wouldn't recommend everything I done here.

Nice Flying, Nice quality video! What camera are you using and is it capable of FPV?
Once I settle on a frame my next task will be to adding FPV as I'm a horrible pilot!

And you think FPV will fix that??? (puzzled look), it's actually harder to fly FPV than not IMHO...

I'm grasping at anything to improve my piloting abilities.
With FPV I'll would always be looking forward so I ASSUMED things would improve.
Thanks for bursting my bubble :P

FPV piloting is more intuitive, with the VERY little experience I have been able to have! but, that don't mean easier!

cause, it's hard to know if you going left/right, up/down!

Thanks. Using a Sanyo Xacti. It's a strange format since it's standing, but for the other frame type I'm contemplating it will hang from it nicely in a swivel which will be servo driven. I have no idea if I can get the analog signal out of it to transmit over FPV link, but I actually think so!

This is how the setup for this video looked:

About FPV: me personally think it's VERY much easier flying in!
This is are my funniest and scariest FPV flights:

Back in the 1.7 SW days... And Wii sensors.

Nice flying Honk!

I think flying FPV is the easiest way of flying as there is zero possibility that you pull a stick the wrong way when you are moving towards you.
Compare learning to drive a RC car and you turn around and drive straight at you

With FPV you are always in the "right position" and always move stick accordingly.

About the sensors....

On my MultiWii I only mounted the sensors with a piece (2*2cm) foamy-like material that is an anti-slip mat with adhesive tape on the rear side.
1 layer between frame and WM+ and 1 layer between WM+ and NK
(stacked sensors)

works great and no oscillation at all - so the talking about a heavy sensor board must be specific to AQ.

In this post you see my 1st WM+ sensor mounted straight onto the PCB

The other test was to mount 2 sensors stacked and that also worked great

However, consider your field of view ... FPV you're limited to what's exactly infront of the camera. You can't "look up" so to speak, and see if there's an obstacle above the vehicle. You can't look to the side without having to physically rotate the vehicle just to see what's around you (I'm talking about a particular person on here flying in a kids' park) ... I'm not saying it can't be done, what I'm saying is, FPV isn't as easy/intuitive as a lot of people think it is. Personally, I wouldn't start off flying FPV if I was still learning. But that's just me.

Thanks Kalaspuffen! :P

No, it's this idea of having a small 15g sensor board on a 1500g vibrating quad that doesn't make sense. Then the sensor board will have none of the inertia, thus requiring very loose and small vibration dampners and then it can start to rock itself (think rubber bands). Our AeroFPV frame for example uses a technique where the arms (and motors) are all separated from the rest of the frame with rubber grommets, making the quad 2 pieces weighting about the same, rather than big on small... It's a basic mechanical idea about moment of inertia.

And yes, I like FPV for the fact that you always have front in the front! :P

I like your idea about the pearl majingies for spacers, think I'm gonna do the same!

No problems - use headtracking connected to your camera.
A wide angle lens us usually best to have greater FOV.
It might be that play lots of games on my computer and fly around a lot...
