Need (well, want really) a new ESC
Hey all,

I dont think my ESC (align 25A) is good enough. I'm just doing hovers and circuits, but after 7-8 mins flying time, the LiPo is warm, and the ESC is very hot. After a few mins the motor cuts out and the heli falls out the air for a split second.

I have a 420LF brushless motor and a 20C (continuous) 2100mAh 11.1V LiPo.

I think my battery is too powerful for my ESC.

I am looking at simply getting the Align 35G ESC, as I don't want to spend any more on an ESC.

Is the 35G any good for basic flying (and eventually basic 3D)?

Cheers
As far as they know, I already had it!

Get a Jazz and forget about needing an ESC upgrade again, forget about curves, just fly. Will be best money you spend on your heli!

It's not your battery, 25A ESC is just a bit marginal on a T-Rex. The 35A Align one will do the job, a P35 will be better and as Edge said if you want no more hassle get a Jazz. Quality costs and the Jazz is £100. Choice is yours Phil

Thats the thing, I just cant justify spending half my monthly wage on an ESC.

I would love a jazz, but I cant go luxery on everything. I already have a GY401, and I need more batts, so I cant afford to buy a top notch ESC.

Thanks for the top help guys, just wish I could afford to follow it

Castle creations phoenix 35 couldn't hurt. I havn't made one hot on a trex yet. I'm not positive, but I think they are near $70 now days. My align 35amp esc cuts out too, but thats cause I got it too hot in the first place.

Yup, they're $74.99 at Heli Direct.

How are these ESCs? Do they have included BECs?

the CC pheonix 35 is a good controller, a step below the jazz but still an excellent controller for the price. programming via computer is really nice too although youll need to buy a pheonix link for that to work. i have yet to make my CC 35 even warm to the touch and im running an align 430L motor with heatsink and a TP 2100 3S battery.

the battery cant be too powerfull for the controller other than using a battery at a higher voltage than the controller can handle. the motor and controller dictate how much current is drawn from the battery, the battery doesnt "push" the current into the power system, it is "pulled" from the battery.

You can also program them without a computer as well
As far as I knew before hearing about the Jazz, Castle Creations was top of the line. I've had loads of use on several model sizes from CC and they make great esc's

CC pheonix 35 is a good controller. I have mine as per the new software and wow!! I can't say enough about it. I am also using governor mode. Real simple to work. I am real happy with the results so fare no heat problems at all!!

the cc 35 ESC is overrated and can cause problems too, first sign
of trouble is the heat shrink melts off the BEC IC. And there
is no arguing with the stubborn owner/cheif engineer either.

With that said I added a heat sink and heat sink compound as CC did not seem to feel any was needed, and have not had any failures.

I did a big post on this a while back.

Unless re-engineered in the last six months, the CC35's onboard BEC is not good. I had one melt down running hard with 430L motor. Too much heat. Solution to run separate BEC will work, but seems to be a "micky mouse" crutch, as opposed to getting good ESC to begin with. I could have saved money and time by buying Jazz to begin with. Buying less proved to be penny wise and pound foolish! Since getting Jazz, I just fly and enjoy progressing learning curve. No messing with settings, no cutouts, no crash related parts replacement, no firmware upgrades, no contributing to product R&D!

I agree completely with edge about the Jazz - it can't be beat. I started with the CC35 and had to get a separate BEC , so there is and additional $25, plus, contrary to what some have said, you do need the link to program it in order to get to some of the heli settings, so that is another $25. It's true you don't need the link to program some of the settings, but do it a few times with your transmitter and tell me how much fun it is!!!
Now you're up over $125, which is just $35 shy of what I paid for the Jazz. Also, do some research here on people that have had issues with interference with the CC controller in governor mode (I was one of them).
Now, I probably would have stayed with the CC35, especially after spending several weeks tweaking the settings, since the new software is pretty good, but the interference issue causing the tail to wag in gov, mode was just not acceptable. If they get that fixed then it might be a decent cheaper alternative.
I would have saved myself money by getting the Jazz to start with, plus saved a whole lot of time and frustration as well.

I will have to try the Jazz one day then. I hear nothing but good things about it =)
I don't use Gov mode on my CC's. I wouldn't know about that either. For what it is worth, All my CC esc's work great, and have never failed.

I run the same ESC and motor and I have no problems. The ESC and motor are warm to touch after 8 mins flight, battery is just warm and its only 12C.
What % throttle curve are you using and pitch settings. If you are using a low % throttle most of the flight the ESC has to dissapate more power. Its not working efficiently. If your curves are ok then it is possibly the BEC which runs the servos,RX and Gyro, depending on what servos etc you run and how much work they are doing the BEC may be overheating which causes the BEC to shut down. NO POWER. Is the ESC getting good airflow or is it tucked away under the canopy, this can also increase your problem by not getting rid of the heat.
You dont say how hot the motor gets.
Another possibility is gear mesh with the motor and having the tail belt to tight, both these will cause the motor to draw much more current and make the ESC work harder, because the battery is a high discharge one it will not show signs of getting hot so easily. The tail belt does not have to be as tight as you would expect, as long as you cannot push it ovet so the insides of the belt touch then it ok. Just make sure it does not slip or jump.
I hope this gives you some food for thought and helps in some way

My congratulations to all who use the CC35 in a trouble free mode. I have had good luck with small CC ESC's in planks. My experience with CC35, terrible. I know some who have success with the CC35 seem to think that those who have problems, have lousey setups. Not so in my case. I ran loose tail belt, high headspeed, no drag throughout bird. At shut down, head took many seconds to spool down. I was however running 430L on 13T pinion, along with HS56 servos, 401 gyro w/9650 servo, along with TP2100 batteries. CC tech said, "this equipment does tend to run our BEC toward the hot side! Best to use a separate BEC". An indication to me I rather needed a beter ESC.

Currently on these 90 degree+ days, my 430L and batteries running about 130 degrees after strong run. Jazz in governor mode (headspeed about 3000) only showing about 100 degrees at flight end!

I felt the same way Planehazza and decided my hobby was worth it! Saved up the money & went for it! I've never looked back! Now I can throw any motor of my choice and never have to worry about upgrading my ESC ever again!
You won't regret it!!
and one more thing "DON'T BE AFRAID!"

Yeh I really don't think I will, but I can be optimistic

I am seriously considering a CC35.


Are the Align 35Gs that bad?
