T-REX 700 › The best ESC on a 700???

OK, So I know about the thread on the CC 120HV and the fix, so what the best esc to use on a 700E? I see people using 80s, 120's and 160's. I just had an Align ESC go up on my 600ESP and ruined that heli so I'd rather over do it if I need to. I am still learning so my flying consist of pattern, some inverted, rolls, loops, and such. Any input from you 700 guys is greatly appreciated.

I am serious.....and don't call me Shirley.

80 amp will do just fine even if you start smacking it around. Nearly all of the CC ESC fires on 700's has nothing to do with over current, just faulty ESC's. It seems the CC recall is only for the ICE 120HV but the ICE 80HV also has the problem! I recommend the Kontronik Jive 80+HV, with sport flying you would be fine with a Kontronik Jive 60+HV but if you are wanting to progress to 3D its best to go straight for the 80. You would only need a 120 if you were to run 2200+ rpm and be draining the packs in 4 mins or less.

60% of the time, it works every time!

I'd go for a Jive 120 HV : reliable ESC and integrated BEC.

I have a CC120HV + Hercules Super BEC. Works fine (150+ flights)... cross my fingers.

Thanks Harvey. Only problem is the Jive is expensive. Maybe a CC for now and a Jive in the near future?

spend the money now.. THink about it like this If you put a cc120 esc on your bird and it goes up in flames you might not have a heli to put the jive on in the near future..

Get an updated ICE 120HV - you will be happy with it.

There is always Scorpion or Hyperion ESC's, they do a 90HV.

One thing you could do is go for the CC120HV but be real careful :

- Bench test it : take blades off and check the ESC before atatching it on the heli. Have some wire cutters handy if anything goes wrong, that way just cut the wires and get the ESC away from anything. You can actually mess around spooling up/down, running for a few minutes on lowish throttle (60%), maybe even load the head a little by pressing on the head stopper (with some thick gloves, I've never done this) --> during all this you can also check servos etc are all fine too under these working conditions (vibrations, ...)

- For the first few flights just hover around and keep wire cutters and gloves ready to rip if out if anything goes wrog.

Then if something goes wrong, hopefully the heli won't be too damaged, and CC will warrant it.

AGAIN : Don't forget that probably 95% (my guess) of CC120HV are working just fine (and 100% of the five T700E I've seen!) and DON'T go up in flames. These people just aren't on RR!

Also do not run outrunner mode on the CC ESC and keep battery to ESC power leads less than 12 inches long, the shorter the better. Keep the ESC at the back of the heli so you can easily blow it out IF it catches fire on the ground and if it catches fire in the air the blades will blow it out, DO NOT put it under the canopy.

+1 for the CC at the back. I believe it's important to have it in the air flow + easily removable in case of bad luck. I'd be curious to see what damage occurs except the blades (if they happen to be above) when it burns on the back mount, I doubt much gets burnt..

Just as a matter of information, my PWM is in Outrunner mode, because that is what's advised in the CC manual. I know I've read here a few times that outrunner might be causing issues, but I don't know where this "rumour" comes from, and on my setup it seems not to be an issue.

The short wires are important (any electronician will confirm this, and it's also stated in the CC manual). I only needed to add 12cm (approx 4 inches) to my red lead. You must take the "short lead" constraint into account when setting up the battery tray etc. Many people have massive leads (40cm) coming right from the front (this should be avoided).

GREAT info guys! Thanks alot for the help!

Yeah, its a shame, if my ESC hadn't have gone up on my 600, it'd be rebuildable and not that bad or costly to do, but with the fire and so much heat, I don't trust anything from the boom forward. Of course that esc was mounted on the side of the frame and was in airflow, which might have kept it from popping until it got on the ground. I like the top mount much better, that would have prevented what happened on my 600.

I am serious.....and don't call me Shirley.

It was on the CC site. It said not to use outrunner mode for helis. I would change it to 8khz or 12khz.

The new CC ICE 120 Rev 2 would be my choice. If you already have one send it in for a free upgrade. If you need a new one it should be in the stores by late Aug early Sep.

The 160 also got the upgrade and some with the Rev 2 sticker has already been shipped. The 160 is not on the recall it also gets the upgraded parts.

Wow nice flying. I have a CC Ice 80HV on mine too but how is your max amps so low. I run my headspeed 2025 and see max amps as high as 148. No problems so far but I am a little worried. My only guess as to why my amps are so high is collective management.
