Im finally at the point to where I need to start looking for electronics that will get my Proxflyer clone in the air. Im going to start using 3 channels but I want to have a 4th available for when I try the dual tail rotor version. I searched the boards and google but did not really see anything that I thought was too usefull. Im looking for a range of at the most 200 feet. If its more I wont complain. Weight is definitley an issue. The only way I can think to control this little monster would be with a pic. Here is a ESC circut I found searching that controls 1 motor.
ESC (http://www.webx.dk/rc/ecs2b.htm)
On the schematic there are 3 I/O ports open which would give me 1 more motor. Instead of making 2 Im sure a 16 or 18 pin pic could be used. 2 of the motors will need to be bidirectional(Tail Motors).

I havent found a small FM Rx schematic that I could use. I either did not like the size or the parts were too large.

Any help or links appreciated. Thank you.

Hi crazifunguy,

Come to the Indoor Forum and do a bit of reading there, lots of stuff ;)

Depending on the final weigth of your ProxyFlier, FM RX may be too heavy.
Perhaps consider AM or IR.

To start you off, have a look at Koichis web page

and more specifically

If you want to download PIC codes, you'll have to do it without Google

You can stack PICs to decode other channels ... etc ...

Cheers

I have been playing with a small AM setup and everything imagineable interfers with it. I crashed because my cellphone started to ring. Ir is not an option because I plan to add a micro wireless camera to it. Im going to need to weigh the components and figure out my max payload before I go any further. I dont want my rotors to be too small for the weight so I suck up too much battery with too much throttle. I'll read on the indoor board and start to get some numbers together.

Voltage question....If im using 1.2v pager motors how do i get the ESC to that voltage....The lowest I have seen is 2ish volts
