now i m looking for a 3 axis gyro (so i dont have to use 3 separate gyros),1 tx rx  4 channel ,3 mixers.

any suggestios. 

I think a 3 axis gyro is pretty expensive. Not sure though, Never bothered to even look for one.

Never came across a 3 axis gyro working with servo interface. There flybarless systems for helis are the closest, but not what you need. If you are looking for an electronics project, then there are 3 axis gyro module. It'd be far easier and cheaper to just buy 3 gyros.

Pankaj, Whats the MAX budget for this project? Some experienced people can tell you if its possible or not to implement/finish the project based on that.

http:// ok i got it i t will be easier to use 3 gyro. budget means we can spent 3000 on gyro

Nice link    Looks like a lot of information is useful for people who are building quad rotors too (the "3 Idiots" effect!).

Each gyros cost 700 bucks though, but can be reused in any other planes/Helis in the future. Just my suggestion .

from where can i get 700 rs. gyro??


thanks for the help btw

I got from hobby city. Goto Gyros section you can find many.
