Also for helicopter the motto applies: power can just be changed by more power !!!

We have developed a new, very capable motor -HP 370/40/A2 Heli-. The motor based on the since years proves HP 370 and became optimized spezial for helis. For more maximal cooling the engine has a double-aktiv-fan! One to cool the outside of the motor and one for inside-cooling. By the 10 pole constuction the engine has a lowly internal resistance, which gives him the necessary climbing rate for quick reversal of load. The performance s about 2,5 KW.

Successful tested with the Joker 2 !
