Pipefish this is a page that I found that tells you how to make the blades from sheet plastic

I haven't tried it yet I bought blades from
http://www.airdyn.com/roswell/parts.htm
but they don't provide enough lift on my setup:
motors:

battery:
http://www.lightflightrc.com/HTML/products/2600-2S.htm
right now i'm using my micro rs4 radio and 1 speed controller pluged into all 4 motors giving them same power.
I don't get enough lift with Roswell Props, EPS 280-C, 5.33 gear, all 4 motors draw like 8.5 amps
I also bought toddsmodels 10x4.5 Counter Rotating Props, on my setup these props draw under 5 amps and create even less lift that roswell props.
in desparete attempt to get my flyer to fly I cutup some floppy disks and used plastic from them to create extensions to rosswell props which i duck taped to the ends of ross props.
It somewhat flies very instable.
Spaceclam I will take your advice and lower my cg.
I think I have a problem because my EPS 280-C spins my props way slower than your EPS-300C-C but you draw 32 amps
at those amps what are your flight times?
I tried EPS 280-C motors because I was trying to go for 10-15 min flight times.
I can't wait to get it all right.
I have BASIC Stamp 2p module and pwmpal I bought 1 hobby gyro (will have to buy 2 more or figure out how to connect tokin ic gyros that vary voltage as a function to my basic stamp "ADC?") I'm somewhat new to all of this and i'm not an electrical engeneer like ADI.
I'm building a curcuit board for the flier
pwmpal connected to 4 MOSFETs and 4 diodes to motor.
I think thats what I need to safely drive speed control my 4 motors from ic pwm.

Good luck to all who try to build a dragonflyer.
