Motor performs well but more technical info is needed.

Jan 28, 2021

A technical specs sheet is needed. Performance data on 3s, 4s and 5s, props used, max amps, Wattage, Thrust, Efficiency. Note: Leopard, BadAss and most other motors have spec sheets.

I use this as a replacement motor for my 2-meter Parkzone Radian and it fits perfectly! And, works great! I just had to purchase another ESC though. But WELL WORTH IT!

SK3 4240-530KV

Nov 06, 2020

Waarom wort er niet meer aangegeven gelijk vroeger de celen en daarop de prop ?
Vroeger werd er ook een vergelijking gemaakt met de waarde van de elektro motor tot de methanol en eventuweel de trek kracht van al die dingen is er niets meer te vinden dit is niet klant vriendelijk.

Just received the motor, very disappointed in the quality of the supplied hardware. Why are these motors not supplied with socket head bolts for both mounting the prop adapter and motor mounts, further the prop adapter is too light for a motor of this rated power driving a 14X7 prop on a 5S system. further the bullet connectors are too small to fit my 3.5mm connectors on the ESC. A lot of fiddling about to get it right, I will report once the motor is in service. My recent purchase of a SK3 motor was also disappointing in the same area, though it performs brilliantly in the air.

Motor ist hochwertig verarbeitet und leistungsstark. An Zippy 5s und Aeronaut CC PP 14x8 Stomaufnahme im Stand 43A. Leider passt der Propadapter nicht zum Motor, da nur M6 und 24mm lang, also viel zu kurz. Es ist der gleiche Propadapter wie bei den 35xx Motoren. Schade !!! Wnschenswert bei dieser Motorengre wre ein Adapter mit mindestens 35mm Lnge und M8 Gewinde.
