Building my own DIY submicro heli

Hi all

It's my first post here

As mentioned in title. I loved to watch pixel(by alexander van de Rostyne) heli series and all your work here.
I'm so excited about building my own bugger. Cant wait to fly it over my room.
I plan to use:

-"200" brushed motor

-5A esc

-8g tailmotor

-GWS 5.4g servos

-4g receiver

-3s 360mAh lipo pack

This is what i made so far.
Oh, and wish me luck

Ok, swashplate is ready. 5mm ball inside bearing, upper and lower plate from plywood. Motor and gear on its place too.
So, take a look and tell what do you think about it, please
I'll need some support and motivation from you

Wow, got me thinking about building one of these little guys once I have gotten the hang of my NR3D. I'm impressed with the wood work, but (pardon me if this is a dumb question) will it hold up to the rotational forces created by these things?

Yes it will. Plywood constructions are very rigid. Beside that i reinforced it with CA and tested with blades on under 2000rpm. In fact rotor and head are very stable. I'm thinking of adding some weights on paddles to increase stability.

Interesting blades, are they made completely from balsa? If so, do you plan to add re-enforcement to the hub area?

Blades are completetly from balsa with little plywood mounts for screws. I think i'll cover them using some solarfilm and eventually add some weights.

increasing the weight on the paddles,will it increase the stress on the rotor hub?

Ofcourse it will but it doesnt matter, this little rotorhead is very strong and rigid. I'm safe until the forces will pull it exactly contrary, otherwise i'll end with vibrations.

Servos and all links with mixers installed. I decided to use mechanical mixing because of proper cg. Now almost everything is done and i'm waiting for kokams, esc's and maybe gyro(ikarus micro-gyro).
Hmmm, i can't still find anything that would match as canopy...

Good work! You have the simplest chassis I've ever seen. The way your servos are mounted is new. But your brushed main motor could be too weak for the heli. Why not go brushless?

It's simple and does its work well enouht. Did some thrust tests and everything is ok. It seems it will hang it in the air well. I don't like the concept of big powerfull motors with short blades, heavy equipment and high head speeds. I'd like to see nice, light, simpe and quiet bird floating in my room

Oups, i made a mistake in the begining. It's not "200" motor but FK-050SH, so i shouldn't have any problems with lifting her up
I'm still waiting for kokams and esc's.

By the way, how can you compare 050 to IPS? I know both weight about the same(15,16g) how about power, current, lifetime and efficiency?
