ESC and BEC questions

[Bob O]

Which ESC do you use or which will you use?

And do you run an external BEC or plan to?

Of the current setups we see in the videos by Sebastian, Dave, Caleb, and Andy........I wonder what ESC's they are using and if they are using an external BEC.

I currently have an ICE Lite 50 that I plan to use. I was going to use the CC 10A BEC, but was told and have read that the MKS DS92A+ servos I bought were incompatible with that BEC. And guys are saying that the 3A of the internal BEC isn't enough.

Thanks guys, looking forward to input.

I always used the bec from ice lite 50 and now from the yep 45, no problems.
I'm using ds 95's, that has the same kind of motor as the 92+.
the hungrier servos are the 92, because of their motors.

Here are the cyclic servos I ordered:

And the tail servo:

Here's the thread that says these cyclic servos are incompatible with the CC10A BEC.

If the Pro/Team pilots don't have a need for an external, then I for sure won't.

YEP BEC worked fine on my E325, expect the same on the Warp.
I've since splurged and picked up a used Jazz 40, plan on using it's internal BEC as well.
As long as VB Log shows no voltage sag issue after a flight it should be good to go.

[Luigi_tuga]

I was not aware of that situation.
Weird stuff

Bob, I know Sebastian was running a Koby 50A Esc which has an internal bec of up to 5A. That's what I ordered for mine, using the same cyclic servos you have listed but a 95i for the tail. Sebastian looked to have no troubles with that setup.

[Caleb White]

YGE 40, yes, using internal BEC, 5.5V. Just get a good ESC and have a governor and BEC all in one package.

[Rob43]

Without question, Koby 40. Excellent BEC, simplest to use governed setup. No extra program box to connect. Work horse electronics.

Does one need the Progdisc in order to program the governor and/or access the finer points of programming like with the Castle? The Progdisc is about the same price as the Koby 40.

Or is the Kontronik that good, that you just set it for Heli mode and call it a day?

[GimpyGolden]

If you are good with 12 second soft start and 5.6V BEC just set Heli mode 4 and done.
if you want to tune finer points or update FW you'll need Progdisk.

I have both the ProgCards for my Jive's but never use them.

[Rob43]

They don't get that much discussion since there's not much to adjust. Most dismiss them due to price. Many still go buy external BEC's, program boxes and less expensive ESC's and some are happy and some not. It's not often been a topic to spend much effort on. I figured it made sense to buy a bit high for the ESC. Clearly they are the weakest link on the power system of nearly any heli. Sometimes, we hear of BEC''s failing, or a servo, but more often an ESC, at least in my exposure to the issues. I've been very happy with K.

Just got done reading about the K and watching a Finless video. Seems just like you said, set it for mode 4 and that's it other than adjusting throttle curves for the head speed you want. Don't have to worry about adjusting governor gain, motor timing, pwm, etc?

How can it be that simple?

You dont need to adjust any of that, the ESC figures it all out (and changes it depending on motor load as well).

Only problem I have with the small Kontroniks is there is no equivalent to the YGE gov store mode. With mode 4 whatever HS you get at the end of spool-up is what it governs at. So if you spool down on a partially discharged pack the next time you spool up you get a lower HS, the same thing happens if you have different packs.

The large ones have another mode that is like gov store (mode 5 on the HeliJive AFAIK).

[Rob43]

That's interesting, Desertstalker. I've seen comments about this, but never noted it in practice. I thought once or twice I could tell, but it's never been significant in my flying. Either way, I am not knowledgeable about the YGE. I know they are high quality, but little else. I have an 80 in my 6HV, and 120 in the 7HV. I have recorded many flights using JLog on the 120. It's a work horse. Easily handles the big power motors too.

[GimpyGolden]

You got it Bob. Jive/Jazz/Koby figure it all for best performance.

Difference in modes DesertStalker is trying to explain boil down to this.

Mode 4 optimizes on a per flight basis. If you have an old weak pack and a new/strong pack your head speeds will vary some from flight to flight depending on pack used . Gov performance is the same but max head speed reached can differ.
I have seen this is pretty minimal through JLog logs. My old TP pack will run around 2120-30 on my L600 where my newer stronger Hyperion pack will run 2140-50

Mode 11 or HeliJive M5 you would use your weak pack to set head speed the first spool up then Jive stores this and applies head speed flight to flight regardless of pack used. This mode is not available in Jazz/Koby. If all your packs are equal rating and age this mode makes no difference.

Not entirely, I have a Jazz 20 on my X2 (works the same in mode 4 as a koby AFAIK). If I fly for 2-3mins and then land, the next time I spool up the HS is down from the normal ~3800RPM to ~3200RPM (due to the drop in pack voltage from 4.2 to ~3.9V). So if you are practising autos it gets pretty annoying.

Mode 5/11 or YGE gov store and you get the same RPM every start up.

[GimpyGolden]

Huh that's new one to me.
Jive does not behave this way. If you were to fly down to 3.85 then disconnect and reconnect it would yield a new head speed but not from hitting Hold then re-spool.

I don't recall my Jazz 55-10-32 behaving as you describe, maybe they fixed this in a version change.

Perhaps, though I could have un-plugged and forgotten, I was doing setup when that happened (teensy helis are no fun to auto).

Is the Kobby 55 overkill for the Warp 360 using MKS DS92A cyclic and MKS DS95i tail?

Would the Koby 40 be a better fit?

Thanks

Sebastian is running a 55 in his and that's what I grabbed for mine, will be fine. Overkill, not sure on that one.
