ESC for Humming 3D PRO

[mplourde]

Hi,

I wanna know witch ESC do you use with your Hummingbird 3DPRO???

Thanks,

[flyinfool]

Depending on your choice of motor either the Phoenix 25 or 35 will work.
The 35 does have a better BEC circuit especially the new one.
I have never tried an ESC from anyone other than Castle Creations.

Hey,

The Sky & Technologies Quark 23A ESC is a good make also. Jason Krause use's the 33a version in his Trex so there's got to be something in it.

I use the 23A Quark in my own 3D PRO and it works very well. Some say a little more involving to program, but once your used to it it's easy.

The internal BEC is also very good on the Quarks, hence why a lot of people use them.

I see the BEC is a good topic of disscussion... I have a Phoenix 25 on my 3D PRO and I think the BEC is not enough strong to support all of my electronic. My motor cut sometime when i'm flying. I have tried to disable the current limiting to verify if this could help me....

Hey,

I've been learning more about this lately helping some fellow fliers with Trex's, basically the Align supplied ESC's are just not capable of powering all the servo's. With most ESC's if you read the instructions they do state no more than 3 servo's can be powered by the internal BEC, in a heli we have four for the controls plus one extra practically taking into account the gyro!

I must admit to not having problems with the Quark, but after the Trex problems I have learnt it has a nice powerful BEC and so this maybe why.

Motor cuts is what my friends are still getting on their models, even with CC35's and seperate external BEC units fitted. Turning into a real nightmare to fix these little models with more money thrown at them week after week.
I'm thankful my first steps into bigger electrics (Swift) are going well so far with no hassles. But I am learning lots from other peoples problems :smokin:

Ho!!!! With the Poenix 35 also It's having problem!!!!!!!! My god....

My project was to buy a C.C. 35 Phoenix but, i think I will change of brand...

Thanks for this info...

What is the status of the heli of your friend now? Is it having some motor cut problem yet?

[Coolice]

Hey,

At present my friends Trex's now are still having trouble, basically the models appear ok and then the motors just shut down. We have gone through the settings to alter the voltage cutoff (set to 5volts) and removed the over voltage protection to.

They are using PCM receivers & ferrite rings and yet we're still suffering. We are now looking at external interference at our local field to just to rule that out.

The CC35's are great ESC's, the govenor modes are much better than the Align ESC's versions for instance, it's just we can't fully enjoy the models until we sort to silly issues we're getting.
One's coming over tonight to be setup again ready for trials again on Saturday/Sunday weather permitting.

OK... thanks... give us some news when you'll have done some test....

[mplourde]

Coolice, have you some news about the T-Rex of your friend? Have you resolve the wagging/cutting problem on that? :?:

[Coolice]

Hey Mate,

Yes, they appear all sorted out now with a few flights under their belts without incident.

Basically it boiled down to the seperate BEC units we fitted, switching back to the Castle Creations inbuilt BEC to power the Rx. cured all the lockouts.
Why this has fixed the problems we do not know as it was deemed better to power the Rx & servo's seperately. The only conclusion we can come to is that the Jperkins LiPo regulators are not perhaps as good as we first thought maybe and the power coming out of them is not clean.

Being honest we don't have a 100% reason, but since re-instating the CC's BEC they are going well.

Cool...!!!! good new!!!!! I'm very happy to hear that.... Me too I resolved some problem on my humming. I had big vibration on that... Finally the reason was the two bearing on the mast tower who was out.... For my cutting problem, I disabled the cutting protection on my C.C. 25. It's was at Insensitive before, and now, it is at disable. This relsove most of the cutting problem. It's not happen since that...

Have great flying time !!! :smokin: :wink:

[Coolice]

Hey,

It's strange you say that about a bad vibration as I to have one that so far I have been unable to fix. I've changed spindles, main shaft the lot.
I'll do as you have and change the main shaft bearings just incase these are at fault here as I haven't replaced them yet.

You do have to remove the current limiting on the CC controllers it seems to stop them tripping out. In all the posts I've read so far no one has smoked a unit yet through over current and so it seems ok.

We're all looking forward to doing some major flying now models are sorted etc. we're just waiting on some decent weather here in the UK. It's either raining, or bitterly cold and windy :arggg:

[mplourde]

Cool...... Give me some feedback when you have been replace the bearings and have flown sometime!!! Here in Québec Canada, it's winter!!! So our season of outdoor will start only at the begining of May. :( So, prensently, we fly our 3D PRO in Indoor place. We keep informed together... :wink:

basically the Align supplied ESC's are just not capable of powering all the servo's.
I have to disagree with that statement! Several of use the Align 35amp ESC with 3 Hitec HS56 servos, a Futaba 401 gyro and a Futaba 9650 digital servo on the tail of a TRex with no problem!

[mplourde]

What do you expect is causing some problems for me and Coolice, Gary?

How long is your fly? Do you fly anough amount of time likes 10-15 min. or just 3-5 min...?

Hey Gary,

Some people are using the Align ESC etc. without issues, but there are is a large percentage who have had real problems with the standard controllers.

With most ESC's if you read the supplied instructions, Castle Creations included, the internal BEC's are not rated to power more than 3 servos. In a helicopter we're already using four, five if you add in the gyro as well and this is where problems and excess heat issues can creep in.

Everything I have mentioned above is from personal experience with the products mentioned and then from chatting to others about the problems encountered. But it's good to hear your not having any problems in your own setup.
