Hey guys,
I'm looking to build a quadcopter that can fly 100mph, has at least 5-8 minutes of flight time, can hold 90 grams worth of fpv, stays nice and agile, and costs about $250 US, sans fpv costs (less is preferable). I've laid out a build and plugged everything in on eCalc and I get 4.3 minutes mixed flight time, 8.8 minutes hover flight time, 100mph max speed, and 5.1 thrust-weight ratio. Do you think these numbers are accurate?
The current setup I have is:
Diatone Blade 250 Frame
Mini APM 3.1 Flight Controller
FrSky X8R Receiver
RCX H2208-2300kv motors
Hobbywing X-Rotor 40amp ESC (OPTO)
HQProp 5x4.5x3 bullnose propellers
Turnigy nano-tech 1800mah 4s 65-130c 1.2mO Lipo
AUW comes out to be about 825 grams (including fpv) and the total cost is just under $250. I will be buying primarily from banggood and hobbyking, but I will be buying the motors from myrcmart and the propellers from getfpv.
Do you guys have any suggestions of how I can improve this build or meet my requirements in a better way?
Thanks,
