Coyote`s Eazystar Build

[Coyote]

Hi Lads, well its about time i did an Eaststar build at long last so here we go.

I cant do it as per website ones, that would be giving away trade plans, so ive set about doing it a different way. Not much, but different equipment spec and fitting.

Lets start with the fuse, i always install everything with the nose to the right, no idea why its just the way i do it, i think its so my right arm, dominant arm is in th thick of it and my left arms the tail side that not a lot ever happens. Weird but its habit :)

So everything gets installed this side which is nice and easy to see how everythings done :)

Ill update as i go.

Spec list :

Motor - 2212-06 28A 2200KV SP Brushless Outrunner Motor V2

Lots and lots of power to get up high and cruise round for ages

ESC - Undecided yet but 40 amp and low RF noise

Servos, HTX900`s all round. Top servos, cheap as chips to buy, fix and replace.

Wing Spar - Going to be carbon fibre to take the extra weight and very hard flying its going to get

Ailerons - Adding these for sure

Rudder - Extended rudder going straight on

Receiver - 9 Channel Dragonlink UHF

FPV equipment :

Camera - GoPro HD Hero, 1080p 30 fps live linked to transmitter

OSD - EZOSD For antenna tracking and past experiance made this decission real easy

Transmitter - ImmersionRC 2.4 Ghz 10mw 4 Channel

Pan servo - Futaba S3001 with servo extender for 180 degrees travel

Lipos - 2200mah Zippy Flightmax but going to experiment with larger capacity working up as i see how the weight is

So far ive started work on the fuse, and cut it out to how i want the equipment to be placed. Work out where everythings going to go :)

Looking good so far Ian, can't wait to see the rest of the build!

[Badlands]

cool build - i like the magnet idea.

[TerrorTrooper]

looking good Ian!!  ;)

Those EZ*'s are addictive!!!

[Coyote]

Cheers lads, i got the magnet idea off kelton, if i need to replace any sides of the fuse i can, or tail or just to get inside it at any point.

Ill crack on with the EZ pod in a bit :)

[Peter]

I like the magnet idea.  I'm interest to know how much weight that will add and if the extra metal will cause vTX interference?

[Coyote]

Ok as the night progressed ive now fitted the tail on.

Camera wise im using a firstpersonview EZ camera pod. But as i had a lot of servo horn failings on heavy landings perviously, the idea of the gopro flying off and damaging the expensive lens is something you dont want happening at all. Thats why i decided to go with a much bigger / stronger servo with bigger and stronger horn.

This meant taking a saw to the camera pod :



Not a problem it cuts really easy even though the plastic is quite strong and thick. Then i mounted the servo to see how much further down it sits compared against the bottom of the pod :

 

Lovely :)

The servo is mounted on top which normally would put your camera high and you may not see the nose while flying with no tilt. This is not a desired effect as you have no reference to which way forward is. But due to the Gopro`s lens you have a enough angle to still see the nose no problem so this is not an issue



Well as time passed i didn`t like the height afterall, i could mount the servo below so took it off and mounted from underneath :



Time for bed, so lets see how far ive got, insides carved out, Dragonlink receiver fitted, tail fitted, magnets fitted, pod modified for standard size servo. Not bad. If i have any time tomorrow ill continue :)



Peter : The metal will have no effect on the signal from the vtx at all, but the magnetic fields may, this is why i wont use them on the pod itself being vey close to vtx. Ill have to do some range checks first. But if all is fine then im good to go, if not i can open fuse and remove and glue but i cant see them having any detrimental effects to be honest, but you never know :)

With all that weight in the pod keeping the pod on is important so im going to glue some old 450 heli main shafts in place with holes through the pod. Holes through the shafts so i can put clips through the shafts holding the pod on very well.

But thats for another day :)

Looking good Ian!   :D

I wish I had gone down the magnet route now...  I didn't ready about the idea until after I glued the Fuse!

I see your going with an outrunner too - have you decided on the prop yet?

I'm still waiting for the DragonLink gear, so will have to live with 2.4ghz for now...

Looking forward to the rest of the build!  Our EZ*s will be very similar - would be fun to fly together at a FPVUK meet!

Cheers, Nic
(waiting for some more great ideas to steal for my EZ* build!  :P)

[Coyote]

Cheers Nic, im using a 6x4E Prop for some mntal power to push the admittedly heavy body around at a nice glide or full high speed pass.

Just got in from work and my Gopro`s arrived Yeah !!!

[TerrorTrooper]

Awesome!

Now get Building!!!!!  :D    ;)

[Coyote]

Lol i want to, but tonight ive got two other EZ`s to finish and box for posting so mine will have to wait till tomorrow night to crack on with :(

Edit : Couldn`t help but see how it looks mounted on EZ :)

   

Looks nice n low, glad i went with servo under not over now :)

[mark1975]

looking nice ian looks very stable and looks like it will capture some cracking footage ...looking forward to see it develope

[Swissnic]

One quick qu. regarding the tail mounting on a Fuse held together with magents.  I presume you are going to glue the tail to only one side of the fuselage?  Will this be stable enough?

I was thinking you could cut the detachable side of the fuse about 2-3 inches before the tail and glue this rear section in place to give a secure mount for the tail.  You can then reincorce the tail beam with CF tube to counter the weakness of the actual tail, which will have a solid fitting into the glued end tail section...  You would still have full access along the fuse, and the tail mount would be as strong as a fully glues EZ*...

Does this sorta make sense?  (?)

[Coyote]

Yup that makes perfect sense, ive not decided yet, i think ill be cuttin the tail so both sides glue to it for my purposes. I dont need the tail to come off so i think thats the way im going to run with it.

Decissions decissions lol :)
