Coyote`s Eazystar Build

[Jay28]

Great Ian, you must let us know how that performs in the field!

[Coyote]

Ok next update, been at it for an hour or two today so far.

All electronics are in, motor mount fitted, motor fitted to mount, ailerons cut out and servos fitted.

So apart from Gopro`s base im ready to rock n roll

Looks great Ian!  I see you have caught me up whilst I've been waiting for the Video transmitter to arrive!!!   :P

Looking foward to your maiden video - are you going to give it a go tomorrow?

Cheers, Nic.

[Coyote]

Lol Alas no i cant, im waiting on a av lead from Simon, i think he said he`s expecting them arriving on monday. Totally forgot about it till just then :)

[Swissnic]

LOL - sounds like my prob with the vTx!  Pity you don't live closer - I have lots of spare AV leads...  ;)

Weather permitting, I'll get airborne tomorrow...  Skills permitting, I won't crash!  :laugh:

[Coyote]

Well good luck with it matey

This lead is a special, 4 pole 2.55 mm jack plug thats moulded at 90 degrees so not somethig off the shelf but for FPV pan its spot on the money. Shame you cant do the same with the USB ( angled connector ) now that woul be perfect :)

Ok next update, the Mk.1 Gopro mount has just been finished, ive gone with ultra light ultra strong ply for the construction.

I made a base and cut two slots to the rear to hold the elastic bands on. The bands hold the camera down and because of the forces can not come away.

The camera is also held by velcro, the velcro is also there for anti-vibration too

This is only a mock up but after testing im happy and will go with this simple design :

The naked base :



Elastic backup :



Access for Usb and Av, very important :) :



All done :)

Well just got in from work so i sanded the pod so its more pleasing to the eye. Then thought i should wap the Gopro on it and see what kind of view ill get.

Turns out, even with the Gopro as low to the nose as it is in 1080p you just miss the nose out. So for the highest quality image i can lock down the camera with no pan and not have a nose spoiling the view. In 780p though the nose is in view for general flying :)

Ive hit a strange hurdle though, the pan servo twitches when centred, but only seems to do it when the Gopro is off it ????

Seems not a problem then as it will always be on but i want to know why its dong it. Ive got a ferrite on the servo lead so all i can think is its the servo extender / futaba S3001 servo combo ????

[mark1975]

looks good so far ian far more wider  angle than i though witch i should imagine is always a good thing..

[Coyote]

Ok so apart from the Usb and AV lead which are on route, thats it !

All done, CG done, nearly maiden time :)

Flight weight came in at 1150 grams (40.57 ounces) with a 2200 mah lipo on board. Standard weight is 701 grams. Standard FPV equipments around 250 gram so around 951 grams is standard FPV weight, im what 182 grams higher, bearing in mind the weight of a Gopro thats not too bad at all really.

To go even lighter i could have placed the FPV gear in the rear but i wanted it accessable so had to add dead weight. 60 grams were added for the CG.

So with a bit more balancing with positioning i could have got it down to 1073 grams in total.

Anyway, minus the two wire here it is complete :

god she looks good ian niced and ballanced aswell ..ohh wait a minute whats that i spot on the floor in the corner lol he he

[Coyote]

Yes my next FPV project :) Well spotted.

Im glad i went for the larger more powerfull motor, i think its going to compliment it well. Just got to make the dummy load canopy for it to get it all trimmed without placing Gopro at risk then im away :)

[mark1975]

nice one looking forward to that getting the fpv treatment she deserves lol
