16/15/3 & Schultze Future 12.46e?

I was wondering if anyone could tell me if this is a good combo, I had a CC35 in my E.Pro and it shut down after 5 min. into a flight and it just dosent work anymore(BEC still works)and I was lucky that my heli was about 4 feet of the ground and I managed to land it without any damage but it was really scary! I'm a beginner and I was doing figure 8's, no 3D or anything like that (could't do it aniway with a 16/15/3).
I will send it in to CC. but I don't want to use it anymore in my Heli
so I'll use it in a glider instead (at least I could land the glider safely without having to panic) :-)

I don't belive it had anything to do with the mechanics: 3rd.bearing, ball bearing T/R wire guides, good gear mesh,16T pinion & no vibes.
HS-85BB Cyclic
HS-81 Tail
GY-240
Schultze Alpha 835w reciever (similar to the Berg)
TP 3s3p 6000
CC35:
9VCutoff
Soft cutoff
Governor high
Very soft start
Standard Advance
Insensitive current limiting
PWM 11Khz

I don't think it was a bad sevo, all the componets are new and seem to work ok.
This was my 7th fligh and I would hate to have a crash with it because of a bad controller so I want to get a good reliable controller but it seems to me that the Schultze or Jazz would be a bit of an "overkill" for a motor that only draws max 30 A.

I would apreciate it if anyone could give me their opinion on these conrollers with my current setup.

Thanks !

That motor/battery combo will draw close to 35A for anything above a hover. I'd say you overloaded the ESC. I also doubt the BEC on the Cc35 could reliably handle 4 Servos and a Gyro.

The Jazz 40-6-18 is a very good ESC with a great BEC. I don't know much about the Sculze except that they are also very good.

Spending a little more on the ESC will save you money in the long run. The next time you have a cheap ESC cut-out you might not be so lucky and the repair bill will be more than the price of a Jazz or Schulze ESC.

Thanks CustomPC I'll give the Schultze a try since it has a 46 amp rating & 3 amp BEC
(that way I'll be on the safe side and maybe later on If I inprove my flying I can switch to a better motor)
I was also not happy with the Gov. Mode on the CC P35, if I didn't run it at 100% throttle I would get a slight tail wag.

Update:

I finally recived & installed the Schulze Future12.46e and it works great!

Spool up is very smooth, maybe on the long side at around 10 sec. but much better than my old CC p35 wich used to twist my heli at the begining, even though I had it set to "very soft start".
It also runs cooler and the Gov. mode on the Schulze is great ! , no hunting at all at lower throttle settings, I tried the Schulze at 70% throttle for a few min. and the tail was solid!, I also measured the temperatures today right after a 7 min. hover indoors (22deg.C) and the Schulze was at 41deg.C ,motor was at 60 deg.C, Batt. 31 deg.C, with the canopy on (w/o cooling holes). after that I recharged the battery and it took back 1650 mah.

well worth the extra money
