The following are several test results for this motor when run on a 3 cell 11.1 volt Li-po:
When fitted with a 11x5.5 prop this motor delivered 9090 rpm, drawing 28.60 amps and 1342 grams of thrust calculated at 343.20 watts.
When fitted with a 11x5.5 prop and 4 cell Li-po this motor delivered 12000rpms.
When fitted with a 12x6 prop with 4 cell Li-po this motor delivered 8500 rpms.
When fitted with a 12x6 prop and 5 cell Li-po this motor delivered 9800 rpms.
When fitted with a 12x8 prop with 5 cell Li-po this motor delivered 9400rpms.
When fitted with a 13x8 prop with 5 cell Li-po this motor delivered 8200rpms.
ESC Requirement:
3 cell : DYNAM 40A ESC is required.
4 or 5 cell: 45A ESC
Note: if using 5cell Li-po battery extra cooling is required.
Standard mounting is from the rear. Prop can be mounted front or rear and the 5mm prop adaptors required are included as shown.
Accessory kit including gold plated connectors and strong aluminum cross mount with screws included.
(Informações sobre como calcular a potência do motor)
Potência é medida em Watts.
Ampére (A) vezes Volts (V) igual a Watts.
Exemplo : um motor alimentado com uma bateria de 11 Volts e puxando 20 A está produzindo uma potência de 220 Watts.
Kv significa a RPM por Volta da bateria.
Ex: 1000kv com bateria de 7,4 Volts igual a 7400 RPM (Limite)
1000kv com bateria de 11,1 volts igual a 11100 RPM (Limite)
Obs: Motores com grande Kv normalmente usam hélice pequena. Pois a força necessária para girar aumenta muito com o aumento do tamanho da hélice. Puxando mais amperes. Se ultrapassar o limite , queima o motor ou o Esc.
