Long time since I posted an update. 

 

I thought I would show you what I have been working on.

20160210_210839.thumb.jpg.e4e9a725d38299

 

This is the HK Ridge Ryder. 

 

Essentially I have designed anot alternative 3d printed hatch that contains a small pan camera.

Still early days..  but initial thoughts are it goes well!

Hi Rob, how are you?

Interesting choice of photographic platform

Is there a specific reason you picked the HK Ridge Ryder?

Your film clearly showed the difference between a model with a large wingspan, a lot of dihedral and a tail, and what happens when using a flying wing in terms of smoothness and stability - was that intentional? Were you using a 3 axis gyro stabiliser with this plane?

The main reason media companies use expensive cameras with heavy pendulum fittings is to get the smoothness necessary to reduce the need for the watcher's eye having to re-acquire its target focus, which is very tiring for the viewer. Large sailplanes, with motors or otherwise, are MUCH more stable than flying wings and their product is much easier to watch as a result.

So, was the use of the flying wing simply to see if it could be done with a wing?

One tiny point also - your tilt display was two sets of horizontal lines either side of the centre, whereas most people use an unbroken line to show tilt - it's much easier to acquire by the human eye  which doesn't have to reset the tilt information, with every horizontal section not displaying the tilt, was that intentional too?

Please excuse what must seem like nit-picking to everyone, it's just that I'm always interested in the whys and wherefores of any aerial photography

I think the main thing is to realise that this is not meant to be a photographic platform.

The aim is to find a compact and easy to transport system that can be taken to a slope - and flown with little more than goggles and a spotter.   It can be a big pain taking loads of fpv gear up a slope!

The model was chosen because it is:

A. Cheap

B. Lends itself to the 3d canopy mod without cutting up the foam.

I flew the model with an illuminati flight controller.   This is actually a quad copter controller - and is highly effective.

At one point in the flight just before doing a roll, I turn off stabilisation.   The model was very difficult to keep on track.  

 

For the display.  This is simply how it is prevented using the mwosd firmware.  Nothing intentional.   Just what comes out the box! 

As for platforms.  Big stable planes are much easier to handle.  Just not as easy to transport.  

In the near future I will be posting some videos of a 'new' design I have been working on. (You may have seen it at Ivinghoe ) .  Initial flights have been very positive - with us now moving into second phase design and build.  Essentially I purpose designed fpv glider - with proper efficiency that we expect from our models!

If the new design proves successfully it will be produced for general global purchase etc. .

Not really soaring..

But I am finding it a good training aid to get the kids co-ordinating their thumbs!

Hi Rob

Well done, I thought there had to be more to it than what was shown on the video

At present the ISA members I know are "making do" with a Radian or an Easy Glider and a Mobius (or similar) camera to avoid the weight problems of aerial photography, so I think some of them might well be very interested in your solution regarding FPV, good luck......

Good job Rob!

I like very much the pilot feeling of that kind of FPV vs. the stabilized videos, which I'm starting to consider boring. Just try to think what an FPV racer video could look like :frantics:

Hi all

Boring it might be. but it's provably better for your eyes.......

I don't know if anyone remembers this, but "Saving Private Ryan" the war story starring Tom Hanks, that was hailed for the fact that it was the first  movie blockbuster shot digitally throughout but, even at the time, viewers complained of headaches during the first showings. This was pooh-poohed by the film company who blamed the high noise level on the first 20 minutes of the film for these headaches. Specialists in film technology soon proved however, that these headaches were actually caused by the average person's eyesight being unable to resolve the enormously higher resolution presented in the film, where the amount of visual information was simply overloading the human eye's ability to cope - causing the eyestrain headaches - the noise level didn't come into it.

It's not that "smoother is more boring" it's just that the average eye doesn't find digital data difficult to resolve until you're looking at high-res jitters that  overload the brain's optical processing power - literally it's a completely unnecessary headache

Recent investigations by companies paid to preview the latest Bond film, show film taken of the previewers with their eyes tightly shut during large sections of the action scenes, literally saving their eyes against the assault of the high-res film

Still, far be it for me to object to how you get your jollies Ric, just saying "Be careful of there, people"

Pete,

I can only agree. Guess what? I have not a headache, but some nausea instead, because of a couple of intensive simulator quad racing training sessions. It is known that (shaking) videos are even not good just before going sleep and I usually avoid it. But please leave me alone in my misery, letting me prefer shaken, rolled, pitched, yawed, bikerwise videos instead of perfectly stabilized ones :lol:

Maybe it depends on individual ability of elaborating images: there are people more visual than other. Wanna an example of alien sight ability?

Figured I would mention a project I have been working on for the past year. 

The Skyhook. 

9dd8b1ffee6d4c5bff86cd70d2b510ba.jpg
(picture is of a previous release /development version!) 

The Skyhook is a highly efficient FPV glider.  Glider is the wrong word.   Soarer would be closer. 

It is designed to be competitive,  with excellent glide speed,  and even better thermal characteristics.    In short..  A proper thermal soarer that has been designed with FPV in mind from the outset. 

This hook features a composite fuselage,  with a pusher prop configuration.   The conceptual idea is to allow a pan tilt camera to be installed on the upper deck,  allowing you excellent flight visibility,  whilst retaining the ability to view the gliders nose.   

Optimum power is a 900kv 4 cell..  However 3 cell will suffice. 

Payload..   4000mah is easy.   If you are happy to wire in parrallel..    6000 to 8000 can be achieved.   But really..  You don't need much power.   It can climb on 1/4 throttle..  and hang about for hours if you use thermals. 

Aerofoil is an MH32.   So pretty quick,  and we'll optimised for full camber control on the wing to allow easy changes to flight characteristics. 

Size wise..   2.6m wingspan.   Good news is the entire more can pack down into the box it ships in.   This takes all of 5 minutes to achieve.   The box is about the same size as the box a bixler is delivered in.  So qute compact. 

The model is now in its final round of testing... With production due to kick off within 2 months.   So not long to go! 

The model is well suited to anyone who wants to uo their game to a better fpv model.   It is 100 percent more efficient than any fpv model currently in production. 

 It is also well suited to anyone who wants to get into go  thermal soaring.   It excells in this,  particularly suiting a potential new fpv gps triangle racing class of competition.    

Hope you all like it.   I am excited about it -  its great to see the product,  I sketched out a year back finally being on the verge of production!

Next version of the skyhook is ready to fly..

Assuming all goes well in tests next week; and we should be good to start production!

Currently targeting $250 to $300.  Will vary a bit based on production qty, tax etc..

As a side note.. the glider has been designed to take different front-pods.  We will soon be starting moulds on the regular electric / slope glider moulds.

Essentially..  it has the option of simply being a general purpose slope glider or thermal soarer!  Just a case of swapping the pod!

Interesting.

Who is is going to be sold though?

What servos are you recommending? It looks like four in the wing and two in the stabilizers.

Do you have photos of the insides of the equipment bays?

Hello

Still to be de idea if I sell direct -  or via shops.   That choice will be made very soon! 

Servo wise..   Its really dependant on how you want to fly it.  There is room inside to fit in pretty much anything you want!   Yes..  4 in wing.   2 in stab. 

On all the development models we have kept it to metal gear 9g models.   (939MG) This is plenty fine for the fpv version.   For the pure slope glider version..  I would personally go for something a bit stronger.   IMHO the pure slope I'll be put through more stress than an fpv  soarer! 

I flew the latest prototype last week.   It has exceeded my expectations.    On 3 cell  with a 960kv it will climb away at 50 degrees with 3/4 throttle.   So plenty muscle.   Speed is excellent, and with the full camber control you can slow it up nicely for launch,  thermal and landing. 

What has been really positive if how smoothly it flies..  Whilst still being aerobatic. 

This is an raw video of the first flight last week.   Not bad for its maiden!

Hi Steve

I am in the process of sorting out the finances for a minimum order quantity/production run.

Theoretically this will be sorted by the end of the week; then we have a production run to do!

More videos / install pics will be posted in the next few weeks.

Good news (from my point of view)

Initial production is underway.  Jetting is way to me at the moment are two production versions of the glider.

Some photos of them below:
