Hi !

So I could get one cheap IR camera with one laser and it will get me good quality pictures ?

Is the laser cheap ? Or maybe can we find that laser cheaper ?

Thanks.

If you aren't going for an autopilot, then check out the FPV areas at rcgroups.

Hmm... a quick story if you dont mind...

 

FPV was how I got interested in diydrones in the first place. So give the man a break eh...

For me fpv soon became too costly without an OMGosh button!

At first I tried a stabilization platform with a RTH only type system that used thermopiles, low and behold soon it didnt work well enough to rely on.

Then I tried a rangevideo g4, it had auto-pilot with waypoints (I am in the US), but also relied on thermopiles. Then I discovered DIYDrones!

Right at that time, In comes Mega and soon to follow its IMU, and I can honestly say, that the mega has saved my booty at least twice now...

with at minimal, a good gps tracking with ground telemtry of my fpv flights was crucial, with the ability to take over immediatly upon my command, or even the command of my primary flight partner (the one on the flight line) who may see an issue or hears me hollering.

Or even better yet, the plane (APM) detects an issue like lost signal, and heads home (due to a dead receiver on board)

Seriously these days with my eyes, I want backup safety systems onboard from now on...

Soon we will be able to utilize dynamic pids so that when a wing falls off in mid air

(like what put me smack dab into an ajacent corn field)

It keeps flying! Not flying full speed into the ground as I'm fighting it from a camera, not knowing whats going on with the airframe, and neither does the primary pilot watching it rolling and tumbling to the ground...

 

So no offence Sgt RIC, and truly nothing personal, "but I just dont like giving anyone the go somewhere else gibe"

I also am a big FPV flyer with a similar story, but honestly rcgroups has many FPV threads with a lot more pertinent info than we present here!
My suggestion was in no way meant as a brush-off.

I'm still researching for my MAIN aicraft platform : I want it to be able to move in 3D, so I want a helicopter, or maybe 4 rotor platform.

I was searching for a helicopter first but when I saw the prices for a helicopter, I fell...

Even with the cheapest 450 clone I would need to buy a radio transmitter and all the electronics, costing me like 100€ !!!

So I'm searching for a rotorcraft based platform, if I don't find anything except helicopter I'll take helicopter but if multi rotor is a good choice... Has someone ideas for a rotorcraft based platform, or multi rotor, which would be able to have light payload and more than ten minutes fly time, everything being cheap ?

Thanks !

Haggard, I really like your enthusiasm, and it's great that you want to try something this ambitious. However, "cheap" is a relative term, I don't know what your budget is, but if 100€ is too much, you have to change your project scope. Essentially you're asking for a 10sec kia rio (if you like cars), or the NHS without any queues (if you're political); it could be done, but realistically, not so much.

a little bit than 100€ would be my  budget I think. And I'm sure you can do a cheap fpv set-up.
Instead of a helicopter, which is expensive in electronics and so on, i'm searching for a quarotor. I heard they were way cheaper. If someone has one idea about a cheap & good platform, tell me.

So has anybody ides for a cheap aircraft platform? Quadrotor seems the best option.

i'll search a bit for diy cheap quadrotors.

Hi !

I found a very cheap quadrotor frame for my first quadrotor :

http://hobbyking.com/hobbyking/store/uh_viewItem.asp?aff=5361&i...

I found a cheap camera too :

http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=...

The radio transmitter controller :

http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=... or maybe one cheaper

And if I have money one OSD:

And the 55€ video tx/rx pack.

Now I only need to see which motors and electronics I'm going to put on this frame, has somebody any ideas ?

A good tutorial/build log of one quadrotor with this frame as basis would be a good help.

Thanks,

Haggard

So nobody as experience over quadricopter ? I just need a basic build log of one quadrirotor and possibly some tips to adapt your build log to mine (with as basis the hobbyking quadricopter v1 frame)

Quadricopters experts, I'm waiting you !

I chatted before and I found a quadrotor build log. I did a lot of research. But if u can see yourself, typing diy quadrotor in google has only a few results which don't help me. Check your links before telling me to search.

I'm thinking whats the cheapest option beetween quadrotor and helicopter. Quadrotor seem to be much more costy (more esc, more motors, need more stabilisation) where helicopters don't need that much stabilisation.

What do you propose ?

Thanks.
