you have me beat for size. they even have micro ESC too?

i think you have found the smallest brushless motor.

ill let the guyus who know specs of motors and what one would want for this idea, ill link this:
http://www.hobbyking.com/hobbyking/store/__518__517__Electric_Motors-Micro_Below_22mm_.html

more than 1 micro brushless motor that could work for this idea.

micro ESC,
i think this one would work well.

Here is one really good build: http://www.rctutor.org/3d-printed-quadcopter.html

Maybe any one know with micro FC board can support fly sky protocol? I use 90 with original module and all I can find is thad micro FC support DSM2 protocol

Regards

 

[airhawk]

does the hermit bind to dsmx or is it just dsm2

 

[Spastickitten]

It is only rtf right? dsm2 I think

You can either roll your own with an Arduino Pro mini, MPU-6050 breakout and A7105 module should be able to get the bits for less than <$10 on ebay - though you may have to buy enough to make 2-3 to get the best prices.

Then load midilec's multiwii/flysky integrated firmware: http://www.rcgroups.com/forums/showpost.php?p=25399459&postcount=3

It's not that hard to wire it all up. The one big catch is you'll need a 16mhz arduino but you'll want a 3.3v arduino because the A7105 needs 3.3v. Usually 16mhz arduino's are 5v...but you can find 3.3v ones on ebay just make sure they're both 16mhz and 3.3v.

Or hasi who has an article on his custom board that was linked earlier in this thread has some of his boards available which integrate the MPU and arduino and A7105 all into one board.

I think we need some one to try all these great things but... I have no money soo... if you want to try it post it all here so we can do the same! There is a TON of info now and I thank you guys for that, and maybe once I have enough money I can make one and try to tune it to fly like a nano qx, but again I can't afford a nano qx and I think a good point of reference is great!

 

[jipp]

here is a kit, cheaper than a nano qx.. for the DIY type.

http://www.goodluckbuy.com/mwc-flig...-avr328p--mpu6050-with-motor-and-battery.html

seems to have everything minus the TX for 35 bucks..

[Spastickitten]

The idea is that I can make something that can fly like a nano qx so that I can make something to get similar flight characteristics, but thanks for the link I can get a CJMCU board ARF kit. If you can find one not on goodluckbuy that would be amazing!

 

[Spastickitten]

I also have a question of battery alarms and the such. How will we know when to stop flying? fly sky as telemetry but I use a 9xr and it doesn't have any soo how can we do this?

 

[jipp]

its gonna be so small you will not be able to uyse a voltage meter on the craft id imagine, but maybe you could find a small one.. also the FC may suport a voltage buzzer... that is what i bought for my zmr 250..

so you best bet will be to either get a watt meter, or the voltage meter/beeper to use to get a feel of your battery.. fly, stop.. measure the battery.. then use that to figure out how much time you need to fly. once you know the time. set your timer, and when the timer goes off you need to change your battery.

I thought that would be the answer. I think I might want to look into developing a board like the alienwii but with auto shutoff on the escs.
Also I think I will see if cleanflight or baseflight is possible. I might see if I can make a board thats a frame, esc and voltage in, and frame, or not a frame. I don't know anything but I will try my best! I am a freshman in high school so I really can't do much right now.

well you doing better than me. laughs. when i was a freshman, i was quite the party animal.. i found high school a bore. if it was not for the girls i would not of continued.. my problem with high school is they teach the same stuff you learn in middle school.

of course im 40.. so i had no computers or anything to find new interest.. just the local library, and what was common things to do in a small logging community, camping, hunting, hiking, arts and crafts using wood and natural materials..

if i grew up in the city i probably would of got into RC id imagine. but better late than never, i found it now which works well for me since im disabled.. and can not do all the things i grew up doing. and iv not had a drink in 10 years.. cant drink on my pain meds.

I am hoping to get a nano qx when they get back in stock so I can later do the diy aspect and try to make them similar

 

[Spastickitten]

I want to resurrect this thread just to see if there is any new info.

 

[Snarls]

There's this now from Hovership. A bit expensive for a nano quad, but it does support cleanflight and you can 3D print any frame you want for it.

 

[Spastickitten]

Good one. It looks awesome, it just needs competition to drive the price down.

 

[Spastickitten]

Updated it with Oscar liang's Awesome write up, basically covers everything, I was thinking the winter guys would be interested in this thread.

 

[markyoe]

It would be a decent one for a beginner, who had access to a 3D printer, if the price went down. I think it should be $60 max. Just my opinion though.
