HK / Dr.Mad Thrust Alloy 3S EDF's
Does anyone have any upgrade ideas for these units ?
They are based on :
Rotor Diameter: 50mm 5 Blade
Outer Diameter: 54.5mm
Weight: 67g with 2mm Connectors
Motor: 20mm Brushless Inrunner 4800kv
Max Amps: 18A
Max Thrust: 450g
So far I can't get near to the reported spec performance ..
18A and 450gr thrust on 3S
I get 21A and 300gr on 3S
This is worse than a stock Plastic job as I tried a 4S and it just got hot !
