S-speed L-long R-range
I bought a frame Diatone Roma L5 - with Mamba 2004-1700kv motors at the second-hand for a nice price and that's how it started ,,new lesson´´
I built the copter and started flying. The flight time of around 9-10 minutes (1200mAh) is a nice time, but it was boring
Weight = 238g
I decided to buy new engines.
Velox V2 2306-1950kv - and that's another ,,fun´´ thing :D Flight time maximum 5 minutes (1200mAh)
Weight=320g
but the distance flown is the ,,same´´!!!

Travel speed 100-120 km/h according to GPS.
12% for hover with HQprop 5x5V1S propellers (without sesion 5)
It flies amazingly, just don't hit the ground with it
