430L motor with CC35=HOT
A friend of mine and I both picked up the align 430L motor this weekend at the AMA convention in LA, I replaced a mega 16/15/4 with mine and my friend replaced a AON 3500 with his. Both of us have noticed that the battery, esc and motor are running considerably hotter with this motor. We are both using a 13tooth pinion. I looked through the programing of the esc and couldn't really see anything what would cause this. Anyone have any pointers?

We've been using them here with the CC35 with 13 tooth pinion and this combo runs nice and cool.

Check your timing on your ESC, might be too far advanced. Also, the motor will get very hot if you don't run it near full throttle.- chuckyteets

problems with 430L and CC35
Get rid of the CC35 and pick up a Jazz 40-6-18. It is a far superior ESC and can handle more Li-Po cells with the built in BEC.
The operation including spoolup and gov mode is flawless and worth every penny.

I am using the Jazz with a TP2100 Pro-lite 4-cell and Neu 1105/3Y/3.2 with a 11 tooth pinion and it runs great. More info can be found here (if you have a fast connection):

You don't get a kickback for everytime you tell someone to dump the CC ESCs and buy the Jazz, do you?

Sometimes when people ask a question about their setup, the answer isn't always "dump the CC ESC and go with a 4S battery pack." Most of the time, they actually are looking for help with stuff they already own.

Just dumping the equipment for something else doesn't always fix the problem...

Myself I do like the CC speed controllers, I have been using them for years.

Now obviously this isnb't a speed controller issue, more or less it sounds like either the pinion is too high or they are running at partial throttle. I guess I will find out in the morning...

Is that a 6s 5000 in your pocket,
or are you just happy to see me?

Yeah would be nice for those with problems if one could get some serious answers, not just "buy something else".

Lots and I mean lots of us run the Align escs (both 25 and 35A) and the CC escs without any issues which means it can be done. Jason K run a stock SE with Align batteries with nice performance as far as I've seen. If he can then we can.

Lets adress the tecnical issues that cause problems. Ok sometimes there are faulty equipment out there but most of the time there are parameters that need to be changed, often at no cost.
To solve problems by dealing with them not by running around the problem. Like to solve glitch, buy pcm, to fix overheating esc, buy a new esc etc. Something is causing it and buying new equipment will just mask the problem not solve it.

An overheating esc is a sign of too high amp draw, sure buying a more capable esc will solve the heat problem but you will still be wasting valuable battery capacity...

If I want help with a problem I ask a question about it if I need new equipment I'll ask what and where to get it...ok at times there are no other solutions like if you are running a deteriorating 8C/1500 mah battery on a Rex there is most probably no way to solve that that doesn't involve buying a battery but the most esc problems that come up here can be solved with some technical insight and good advice...lets give it..

excuse me for butting in, I dont have much experience with motor esc etc. You have said to run on full throttle for more efficiency, is this 100% with Gov. or 80-100% with curves ?

Full throttle isn't the same as 100% for governor mode. That would defeat the purpose of having a governor mode, since the idea is to be selecting the desired head speed. If your motor is capable of turning the head faster than the target head speed at 100%, then you may be overspeeding the head.

RobRoy doesn't say which battery he and his friend are using. Since the 430L is an upgrade from what they have been using, it's possible that the extra performance they are expecting to gain from using the 430 is due to the extra current this motor may be requiring from the power source. Maybe the batteries they have been using aren't up to supplying the current demanded by the motor, and as a result, the motor is not running at is most efficient RPM, causing overheating.

It's rare that you can get a marked performance increase in any system without requiring additional power from the source.

I had the same problem and going to an 11t pinion did fix it but I lost headspeed obviously. The problem wasn't the ESC itself but my setup. The bird was a little heavy and my pitch curves were a bit aggresive. Honestly, I found that a little lower headspeed was enjoyable, and the flight times are better. So many factors that can affect motor and batt temps.

BTW, I agree that telling someone to dump a perfectly functional ESC is NOT the answer. I understand that it allows more cells to be used but the person starting this thread doesn't need that. Besides the governor mode issues that some people have the CC controllers work well and I have never had a problem with the BEC on the 25's and I own over a dozen of them.

Well, I installed the latest esc firmware, and made sure my settings were all where they should be, but really didn't change much. Took it out this morning, and this thing is a rocket. I'm flying with a fixed throttle, and can't go above 80% on my throttle curve. I really need to measure my head speed before I go any further, but as it stands this thing is a rocket. It out climbs any of my nitro heli's. Thank you everyone who had construtive suggestions, something besides chuck it and buy something else. finless, you hit it right on the head, did exactly that and all is good, not even the motor was warm after 7 minutes of hard 3d. Outside air temp is only 38f though, but all was still cool upon landing. I'm not sure what was going wrong before, but all is awsome now.

Experience with the CC 25
I started with a CC25 in my TRex late in 2004. I can't tell you how many times I "upgraded" the firmware hoping that Gov mode would work better instead of having to put up with the engine surging. Usually when upgrading it also caused other problems that had to be corrected.

Three cells worked OK for me back then also - except that the TP2100's got too hot at times and the batteries got weaker and weaker until they were unusable (after only 20 cycles)! Of course things may be different today with the TP205 and TP210 balancers that are available and work well.

You are right....the CC25 is a good speed controller but for airplanes!
That is what I am probably going to be saving mine for anyway. I was thinking along the terms of a E-Flight Mini Funtana Plane....saw it and it worked well on TP2000 3-cells. At least you don't have to worry about how it will work in Gov Mode.

Flew five packs today, and I am extremely impressed with the performance. The CC35 esc is working flawlessly, I have more power than I know what to do with and I'm using the 325 blades. I can stop this think instantly, climbing tic-toc's all day. Took some time, but this little trex is really starting to fly nice.Ignorance is curable, stupidity is for life.
