I like design of Freerchobby motors.=this instalation was for 15 Ah A123 cells testing only...we by them circa 400 EUR,
for reinstalation (in place of 40 l tank).
=60 V, 45 Ah.
=we have FREERCHOBBY 500 A /120 V controllers,
and 154120 motor (1000 $ with shipping ) is in DHL hands...
=variant for RETAIRED & HOMELESS...
=complite fuselage with E-Drive is 55 kg weight.
Price for 40 kW motor and controller is really good.
Looking for low price components is not a wrong way - our first electra D-14 has been assembled exactly the same way Only you have to spent more time during ground testing to see real limits.
