HobbyKing's done it again. Check out this deal: their mini-quad with four motors for $33.95! (Or $31.95 if you just let your browser sit open on that page for a few minutes). 

All you need to add to make a RC quad (in addition to your regular RC system and LiPo batteries) is:

That's $90 all told.  Now, in fairness, this is a pretty crappy little frame and it won't last past a crash or two. I also wouldn't expect too much outside in the wind. But what a great way to get started!

@Andreas,

Larger diameter props usually call for lower KV motors. On a 12" dia prop I usually run under a 1000KV motor. Around 800KV to 1000KV.

Just a thought.

Regards,

yes, you're stuck with a 7" or smaller prop. Actually, 2200kV says 7" is pushing it (may low, low pitch). 6"x3 would be more appropriate.

From where can we get the firmware to flash the board. Or do we have to write our own code and flash it?

It's a good deal.  If I wasn't printing, and making my own frames now I'd get one of those.  I think wood makes a good frame.  Nature's version of carbon fibre, and non-toxic.

Honestly, how many quad frames can survive any kind of real crash. (Except my Firefly, of course.)

I use these 1200Kv ones, from HK, and they work fine with plenty of power for flying with 9x5" props and good response.  but if you want to heavy lift, the lower kv, likeDT750, are better.  

The motors that come with this wooden frame are 2300kv, but only run on 2s batteries.  You need them that high with the 2s and they recommend 6x3 props.  It's not going to be a heavy lifter, but should be good for some pretty tame flying.  These motors are not very efficient, I suspect.  It weighs 16g.

Oh and for those, who don't know about HK Buddy codes, there's a web site where you can get discounts from people who post their Buddy codes.  This kit can be gotten for $28,36.  You'll need to have a Hobby King account to see the swarm price.

I would add 20 bucks and upgrade to this frame: http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=...

I have the blueskyrc.com kit. Very durable and you can replace parts if they break.

I am so thankful for all the hard work and information people post here!
What a great community!  Puts rcgroups to bed!

Hello Chris

Could you guide us with your leadership to start making serious UAVs and steer away from toys. If not you who else?

Thank you.

Dara
