Hi guys, I've flown a few blade helis and quads but now I want to build my own H with a flite test frame.
I've been reading around the web for a few configurations and I wanted to try something like this:
http://ecalc.ch/xcoptercalc.htm?ecalc&lang=en&cooling=2.5&rotornumber=4&weight=225&calc=sum&elevation=500&airtemp=25&qnh=1013&batteries=lipo_2500mah_-_35/50c&chargestate=0&s=4&p=1&esc=max_20a&motor=turnigy&type=35|ntm2836-750&gear=1&propeller=0&propconst=1.3&proptwist=0&diameter=11&pitch=4.7&blades=2
Now the maddening thing is I can't get eCalc to build a config with long flight times, switching the 11inch props to 8's increases flight time but reduces hover time??? Seems like I'm doing something wrong with the tool or I don't understand motor/prop/battery relations :black_eyed:
Cheers
