Trex 600

My first 50class helicopter.

Maiden Flight

• Renew the older version tail grip with thrust bearing 3*8*2.5 . CA the screw as loctite alone has problem as the thrust bearing will locked on tightening the screw. My tail problem (locking in mid air and higher headspeed) is now gone.


• Upgraded to Z50B (800kv) and 14s1p A123, CC85HV. Throttle 88%. Headspeed 2000. Max amp 55A, average 14A, Power >2000W. Temperature after 5 min 3D. Z50- 75 oC, A123 45 oC.
