Eurofighter FPV build

[Zeeflyboy]

perhaps surprisingly, no... the old immersion vTX tales 6-16v while the new one can take 6-25v (basically 2S up to 6S)... makes it pretty flexible.

The ESC takes up to 6S-12S... Power should be pretty immense on 8S though. Expecting 3kg of thrust at 65amps... Airframe will be around 2.2-2.3kg expected.

Just updated the diagram slightly

[Zeeflyboy]

So another update, albeit not a very exciting one.

Just got finished hooking up my power system... I didn't like the skinny wires on the eLogger v4, plus I needed them a bit longer... So I replaced them with some nice more substantial 12 AWG.... unfortunately I don't have any clear heat shrink so blue it is lol. Using EC5 connectors (my favourite battery connector!) I made the series harness directly on the eLogger and also used the 5mm bullets to hook up to the ESC (without the EC5 cases to save space).

As per the diagram on the previous page, you can see the vTX hooked up to take power from only one pack so my vTX doesn't explode.

So, it's a bit like Christmas at Zeelfyboy's today....

Santa's little helpers (DHL) brought me these!







A Futaba T10CP to use with my EZUHF and finally after a long wait, my ARC motor and Wemotech midi fan.... wohooooo!!!

With minimal fuss I've managed to bind my EZUHF/Futaba combo, and have the OSD Pro and EZUHF rx talking to each other over PPM Sum... magic! The only slight catch is that I'm running alpha version software on the OSD Pro and beta version on the EZUHF so here's hoping I don't run into any serious software snags...

[Zeeflyboy]

Since I'm using PPM now, I decided to relocate my EZUHF RX right into the rear. This gives it more separation from the ESC/Motor and also means I can ditch the 20cm extension and just plug it into the antenna directly.

I made a custom little pocket for it out of plywood which I then glued into place.. There's a black foam lining at the bottom, the ezuhf just slips inside snugly and then a piece of black foam locks it down from above with a firm friction fit. When the vertical stab is on top the top foam part is held down by that as well. To remove the EZUHF one simply pulls off the top piece of foam and out it comes for access to the USB port etc.

These two wires are all that gets plugged into the EZUHF now, The PPM sum stream on channel 1 and the rudder on channel 4. Please ignore the fact that there is normal servo wire for the PPM line - it's just for testing purposes and I will be using some cat6 s/ftp when I get my hands on some just to be sure that there's minimal interference possibility.

So, Dexter arrived the other day and I proceeded to strip him naked and cut his hands off. I felt a bit bad about it but there you go...

I filled his jumpsuit with some cotton and stuck his hands inside the sleeves. As it turns out he was a bit big so I had to modify his jumpsuit slightly to make it a better fit. I haven't done much else but here's a sneak peek for you guys of the flying cockpit (dexter still even has his blood covered hands for now!). I'm thinking of keeping the hands as white gloves, but maybe a green would look better for the jumpsuit if I can find some appropriate dye.

As always, let me know what you think (video may take a few minutes to process, so check back a little later if it's not working)

 :laugh: Great fun, well don.

My replies gone missing some how, it was there the other day ????

Anyway, looking really sweet, loving the Futaba 10 :) Sexy radio !!!!!!

Its a very very neat install, very impressed :)

The arms moving in the cockpit is unique, I have never seen that before, it looks brill

[Zeeflyboy]

Thanks.

Alas it's not unique, I'm not creative enough to have been the first lol.

I fired up the EDF for the first time today, and holy crap the thing pulls. This thing is going to be a monster! I'm being a bit held back by the fact that the carbon I ordered for wing spars seems to have been lost in the post - no idea when it'll eventually turn up :(

Here's a vid of the cockpit again, but in daylight this time so you can see the whole cockpit a bit better... I also changed the angle a bit so it doesn't look like he's touching himself.

I've also updated my wiring diagram yet again with some more details and additions. I tidied it up a bit and added more detailed wiring, I also added a G-force sensor, strobes (looking at the flytron units) for the wings, included the lighting array for the cockpit, added a LC filter for the power feed to the vTX and a set of caps to the power lines to the ESC to help reduce ripple.

man that dudes going to be cooooolllddd!

[Zeeflyboy]

You offering to pull me a crystal clear custom canopy there pasty? ;)

[Pasty]

sorry, wifes calling... must dash....

[Zeeflyboy]

Thought so... Lol.

It's on my "to try and fail miserably at" list. I have some lean that I think would pull pretty clear, but I think it's maybe a bit thick.

It'll be very time consuming though, and I rate chances of a satisfactory outcome fairly low, as such it's not high on my priority list for now.

[Coyote]

How would you do it so the view from inside is not distorted ?

[Zeeflyboy]

No idea lol...

It can work though. Take a look at this chaps video (the guy that really inspired this build to be honest)...

F-16 FPV

It adds a nice extra layer of realism and also of course helps the aerodynamics. Trade off is reduced visibility in glare, and overall due to the fact that you just can't pull it perfectly clear and smooth.

[Coyote]

Yeah it looks much better, no distortion
