Moin zusammen!
Ich habe den 4240-1050 in einer Parzone Corsair verbaut. Nach einigem Ausprobieren hat sich meiner Meinung nach ein APC-e 12x6 als bester Prop. erwiesen. Mit 3sLipo zieht der Motor im Stand 35A. Der Schub reicht fr senkrechte Steigfluege. Torquen ist nicht drin! -) Ein Rennsemmel ist meine Corsair damit auch nicht gerade. Aber sie laesst sich mit dieser Konfiguration auch durch stark boeigen Wind nicht mehr aus der Ruhe bringen! Mit einem APCe 11x8,5 ist sie nur unwesentlich schneller. Verliert aber deutlich an Schub! Zuvor genannte Lagerprobleme kann ich bestaetigen. Allgemein scheinen die Lager der XP-Serie qualitativ nicht die besten zu sein! Daher machen sie teilweise ordentlich Krach. Aber was will man zu dem Preis auch verlangen. Fr "Hobbypiloten" die nicht das letzte Quaentchen aus den Motoren herausquetschen mssen oder wollen, Sind sie ein echter Preis/Leistungstip. Ich greife jedenfalls immer wieder gerne auf diese Motoren zurck.
Many happy landings,

I'm quite disappointed, as I hooked this up to a Turnigy Plush 60 amp esc, and a Turnigy nono-tech 3.0 4s battery. With this configuration, the motor cannot handle full throttle and emits a horrible squeak at about 3/4 power. This is the first motor I have ever purchased from HK with this problem. Works fine with the same esc but a 3s battery.

I use this motor for my ME-109 .25
The setup include other HK parts - ESC HK-SSH50A and Bat N2650.3S.25
Static results are:
1. Prop TRSP-12x7 - 33 Amp - 358W - 1.95 kg trust
2. Prop XYH3B10x7 - 30 Amp - 342W - 1.55 kg trust
3. Prop XYH3B9x7-5 - 29 Amp - 342W - 1.27 kg trust

It works fine . but i'm a little disappointed in the performance. I was expecting a perkier motor for 1050kv.

13x6 on 3S sees a peak of 50A settling at 45A WOT. 470Watts. Good for a sport plane but lazy for 3D.

Nice motor ashame that the propeller shaft is slightly bent enough to make my propeller wobble .I had to buy the replacement pack to get another Propeller shaft .

Great motor, using it on a seagull Space Walker II, 127cm wingspan with 4s 2200 lipo batterie and 10*7 proppeler. Very fast and about 8 minutes fliying Time.
