I have a Trex 700e DFC running a 850mx (490kv) 13t pinion/110 main gear with a Castle Creations 160 Edge HV . Last year I had the exact same problem with a 160 Edge and ended up using the trade in program for a replacement . The first 160 esc lasted a good amount of flights in the hundreds . Then one day I would spool up and when I try to punch out the esc would go into a cutoff and I will have to land . This happened every time . I contacted castle and sent the esc in they sent it back said it was fixed and the same thing happened . When I contacted them I was told something was slipping . The pinion , one way , motor shaft... I knew nothing was slipping and can here the motor cutoff also . So for testing purpose I switched to a Castle 120 and the heli didn't cutoff it worked fine . I then paid for the trade in program and bought another 160 edge a year ago . I haven't got to fly much this past year maybe 25 flights on the heli . This past weekend my second to last flight I will spool up switch into idle up on the ground and punch out hard the heli went into a cutoff then flew the rest of the flight , my last flight did the exact same thing and it would cutoff everytime I try to punch out now . I came home took the 120 edge out my 550 and tested my 700 it had no problems and flew fine . I again am dealing with Castle Creations and getting told they think the heli is slipping again . I am going to follow the program and send it in but would like to know if anyone has had a problem like this before or if I should switch to a new brand esc ? Any help would be great because if I have to do this once a year it would be a pain !

Here are my Castle 160 Edge settings for my Trex 700 and a graph of the last flight where it would cutoff.
Here is the 120 test graph and a normal 700 flight graph from a previous flight when it works !
