It's not easy to find any other blades that are just right for the Eye One.
I got some of these in my last HK order (yet to arrive) as they are the correct length and hole size to fit. I only got a pack of anti-clockwise ones to look at as they are cheap, but they have a straight leading edge whereas the originals have curved leading edge. The straight edge variety need more rpm to achieve the same lift as the curved ones, which may well shorten motor lifespan. Time will tell.

If you want to know more about one bladed prop usage, look through NightFlyyers videos.

just an experiment of some sort. I guess if you don't have anything to do you start cut off 1/2 of something. probobly an experiment on balance and thrust.

I experimented with a broken prop one time to see if I could get it balanced enough to fly with it. I got the plane flying, but I could never get the prop balanced enough to eliminate all of the vibrations. It did seem to have as much thrust as the two-bladed version though, which surprised me a bit.

Dave Herbert (NighttFlyyer at Youtube) has done a lot with one-bladed props:

Wouldn'T you need that pack here:

But then on the other hand you could use the rc eye one spares as well. http://www.rcheliresource.com/breaki...for-pre-order/

As I mentioned, I only got the cheap pack just to have a look at them, I'm not paying $6 to test them. If I think they will work out ok then I'll get the others on my next order.
I find that the Eye One spits blades off very easily, one of them even stripped a thin core of plastic out of the prop, when I found the prop it had a much larger hole through it and the plastic core was still on the shaft. very odd, and this all happened in the first 30 sec of flying it from new.

Thanks for the HobbyKing link. I may try those. I was searching for an alternate source for these props because of shipping costs. The RCHeliSource link you gave me links to the RCLogger website that wants to charge $30 to ship a set of props to my house. Even the USA venders want $5 or more to ship 4 tiny props. I don't see why they can't just stick them in an envelope and slap a stamp on it.
If I order them from HK, then I can also stock up on other parts to justify the shipping cost.

M,
The air will blow the wrong way on one axis when CCW props are all fitted to a micro because even if you flip the those linked standard CCW props they are at the same angle and pitch. You also can't simply swap the motor wires to change the motor direction without code changes or you will lose yaw control, unless you also flip two of the proper axis motors upside down. So the bottom line is you will need the CW type props for these micros to work properly in their OEM condition. If you could change the code, then you could use all standard CCW props and then properly angle the motors/props to counter the dynamic yaw effects as Simon did with his simple quad build several years ago. See --TIP 8 in the Props section of the Quadrocopter and Tricopter Info Mega Link Index for more info on how this is done.
Cheers,
Jim

Because they are symmetrical (straight leading edge) they can be put on either way.
You cannot mix them half and half with the originals as they are curved leading edge (I don't really enjoy repeating myself, but I explained all this in previous post ).

And if that's over the budget, a V929 is a great choice. A 949 if you want lights and auto-leveling (which I think the ladybird V1 has)

I also love my mini-pet bumblebee. very stable and has auto leveling.

Not all of us charge $5 to ship props (at least shipped in the US), we're working on trying to get RC Eye One and parts.

I wouldn't recommend a mini-sized for indoor flight (MQX, 929, 949, 959 or clones). Yes you can fly them inside, but a micro is much better suited for indoor flight. The micros actualy handle wind better outdoors (than brushed RTF minis). The minis benefit outdoors is that they're easier to see and can handle payloads better, but there are more mechanical parts (more to wear or get out of wack).

The Mini Pet\MJX X100 is a great beginners quad, anything with accelerometers are extremely stable, but Walkera LB V2 and newer versions of the Mini Pet have removed the accelerometers for cost reasons and compensated with advanced programming. You'll hardly be able to tell the difference

The RC Eye One, Ladybird V1\V2 with proper controller, and Hubsan X4 are considered the best in their class for performance. Unfortunately none of them have LED lighting suitable for nighttime flying (which you can disregard if that's something he won't do, but it's quite fun) and the X4 is too small to be seen at distance. If you want to get gouged by 100% markup, you can get the Traxxas QR-1 from your LHS, which is the same quad as the Hubsan X4.
