nickwad, on the nazi and wookong heat/light seems to effect the bara most. Big temp changes over the course of the flight causes some to fall and some to rise when not in gps mode.

You should get a autoquad board or even a wookong+iOSD in that guy to watch what happens with temps over time. both in use and not used just sitting in the sun. start logging the flights see the type of swings you end up with. You will need to write out uses cases, loading this up and it sitting in the sun for say an hours boat ride will have trouble when its time to fly.

I love the look you have going might even get one. But I'd want to have the cam down looking more so I can land on water to use as a fish cam for reef fishing. no point in it being fully water proof with out using it to look in the water.

We are just putting the prototype together at the moment , But after testing and any tweaks to the design have been carried out we will be taking orders if there is any interest.
We are building the prototype to allow us to fly stress free over water for videoing of beach front properties and boats at sea.
all the 'running gear' is going to be the same as we use in the TBS discoveries.
It is slightly longer and wider motor to motor than the TBS discovery (awesome machine when set up properly) but basically the same arm layout.

We have not finalized the price yet but it will be in the region of $1000.
This will include carbon fibre undercarriage and bubble retaining ring, Bubble and seal, Rear cap and seal , Internal floor for mounting electronics, Battery mounting tray. Mounting hardware for undercarriage and bubble.
The bodies will be painted in a single colour of customers choice (multi colours at extra cost)

I will post more pics and video when we are testing ......Nick

I apologize , Yes I will delete all reference to your name. I have changed the heading of the thread to 'Watercopter" until I can find a suitable name.


Best regards Nick

Once again sorry I should have checked !

Nick, can I make a design suggestion?. Something the Aquacopter guys got right is having a "buoyant" type area under the motor so that it doesnt go underwater as much on a water landing. Your design means that although the motors will be out of the water in a water landing if its a slightly wobbly landing they have more chance of being submerged. It might be an idea to add a buoyant area under your motors as well. Cheers

Hi,
Yes good point !
That would help keep the motors up a bit , It was something we thought maybe adding as option . We did not include it as part of the frame as the main aim was to build a streamlined fast as possible machine for videoing boats at full speed and have the capability to take off and land in the water if needed.

Also I think the motors get quite wet anyway from spray and hard landings ?

Nick

If you want it streamlined and as fast as possible wouldn't it make sense to exchange the dome with a flat ( distortion free) pice of glass and pack the GoPro directly behind it? The added weight would be minimal if there is one at all ( less surface and no GoPro housing) while the drag would be reduced?
Wouldn't look as good though...

Nick, if over fresh water you will be fine but I have found over salt water that the bearings begin to fail after a short while. The bearings on brushless motors are not sealed so immersion in salt water over time isnt good. You could mould the bulb under the motors to be round and streamlined.
Im currently slowly working through designing a waterproof Hexa and have one flying and finding a few design issues.
Another issue I have is that its important to have the battery as low as possible in the frame. It needs to be below the plane of the motors so that in the event of a flip or unexplained failure the quad/hexa will land motors up. If the battery is too high and a motor or prop fail then the quad/hexa will land upside down.

This is a short video of the first FPV tests , all seems to be good there is no detectable distortion from the dome just a very slight reflection of the FPV camera lens surround when the sun hits at a certain angle.
I have now fitted a TBS 69 camera and matt blacked the surround also mounted it nearer the globe.
Off to the beach for more testing early in the morning !
I dont have any watchable footage of the watercopter flying as it was too shaky !
I think my camera operator needs to drink less ! Lol

I don't think he has been drinking enough... video looks too stable!
He didn't even dip it into the water to test the waterproofing!

My opinion:

Domes is more streamlines than flat! It's fine as it is.

Users can add a 'float' under motors if they want. I'm not bothered about motors getting wet..

In the vid was that gopro footage and where was it mounted? Was very smooth

What about birds of pray living next to water like
Sea eagle
Brahman or Brahminy kite

Or something like
Albatross- seeing that they are very smooth flying birds spending very most of their life flying over the sea?
