Thanks for the respond Sparks.

I have not bought the Heli yet, but I was thinking on getting an electric begginer ($100-130) which already comes with everything and is capable of taking off with some extra load on it just incase so weight does not become an issue, and I have extra transmitters lying around from my planes with extra crystals I can use.

Also, I have been researching on the net for altimeters and am indecisive on which ones to use. I am looking for a rather small one which would fit well on the computer, mounting is not an issue as I could easily find a way to mount it, but I am also looking for one which I can get to transmit back to the microcontroller so it can in return have it register out with the other Altimeter on the other side of the Copter and compare the two out to make sure that they are at even altitudes. This is not going to be a big scale project so they can be low level altimeters.

I was also considering using the Mini Copter (fits into palm) but was concerned due to its size that I might not be able to properly install any additional hardware on it and/or with a little extra weight, it might not be able to take off.

Thank you for your time and all your responces, you have been of great help to me man

Take care
