Aprs 10 vols sur un avion maquette de 8 kgrs ce moteur est parfait. Fonctionnement trs silencieux et absence de vibration.
Configuration APC 19*10 10S 5000mAh Env 30 A Puissance env. 1100 W. Une 20*11 serait donc parfaite pour atteindre 2000W pour des vols plus acrobatiques.
After 10 flights this motor run perfectly and whitout any disturbing noise.
Light configuration : APC 19*10, 10S 5000 mAh, Current 30 A, Power roughly 1100 W. This is enough for realistic flight on a 8 kgrs airplane but not for extrem aerobatics
For more aerobatics a 21*11 Propeller should be better.A few weeks ago I bought this engine Along with turnigy dlux 160A After assembly and testing it is squeaking sound.
I tried all the options of the esc has not worked until I changed the Castle Creations 120A
Now works great I do not recommend to combine this engine with this esc because it does not fit.Test on the ground. Rotomax 1.40, Popeller 18 x 10. The TURNIGY K-Force 120A-HV OPTO, and 2 x 5S Zippy 4000 Compact 25C, measured 45 Amps and 1550 watts. The Rotomax makes a good impression.im going too buy this one as a replacment for my KD6328s but im not sure as too why when 2- 5s packs are series up it puts out over 40volts but here it says max 37volts on 10s how does that work?
reason for this one is ive gone up from the MAS 16x10 - 3bladed prop too a biela 18x10 - 3bladed im hoping this motor will spin it as the KD smoked up anyone have any suggestion on my combo?I bought 4 of these for my quad x config. works great and plenty of thrust! im using these on 10s with the TURNIGY K-Force 120A-HV OPTO V2 5-12S ESC'S
