Default ESC options?

Hi all, I've been following this forum for a while now, thanks very much for all the useful info.

I'm planning a P380 for my first kit build and I'm still a little unsure as to the ideal ESC for me,

I have a DX6 and plan to use the 4649T with a single satellite and take advantage of the telemetry functionality, particularly mAh consumed.

If I want to use the Brain gov, what's the advice on the ideal HW ESC, if I choose that brand? Bear in mind that I'd like to learn how to auto at some point.

I know some use the YGE60 so I'd like to understand the pros/cons there too if poss,

Edited to add - I'm planning to run MKS HV servos

Thanks in advance for educating me!

Thanks, does seem to be a favourite. Isn't there an issue with tail kick when running an external gov though? Or is that not the case now?

I have no tail kick issue with mine, using external gov in IKON.

I have the HW 60A v4 in mine, using external gov in Heli Linear Mode and AFW off, no issues with tail kick. Love the combination. HOWEVER, you specifically stated you wanted mah via telemetry and the 60A v4 does not report mah used via telemetry, FYI.

Many thanks! So, for mAh consumed, I would either need to use an external current sensor for the HW60v4, or a different ESC (CC with external BEC perhaps) or does the HW80v4 fit in the P380? (I think it's too wide, right?)

I know this mAh fuel-gauge/ESC/Brain integration topic has probably been done to death, so I apologise, but I'm still not totally clear...

Edited to add - actually, after some more reading, looks like a Castle ESC is probably the best bet....

Cheers

With micro servos all around, the Castle ESC's BEC should be okay. If it's your first build, you're likely not going to be heavily thrashing it in 3D mode anyway, right? With agility tuned down (beginner setting) it's an excellent "trainer" for just flying around. Higher headspeeds and high cyclic rates make it a very nimble beast indeed. Dan

Thanks Dan, that does make sense and you're right, I'm not going to be smacking the hell out of it lol

So, a 5A BEC "should" be ok...leaning towards the CC Edge Lite units then, thanks again.

I think the CC Edge 50A is the way to go for telemetry (don't forget to add the resistor) and FBL governing but bear in mind that the peak current of the BEC is 5A, the nominal current is only 3A. It's probably enough but possibly a separate BEC (10A) would be better.

Even though you don't smack your heli's, one of those 'Oh sh*t' moments can put a lot of strain on the system.

Having said that; I have a Gaui X3 using this ESC without the extra BEC and it's fine but these things are a bit servo dependent and the Gaui is a 360, not a 380.

I'm trying to decide between a hw60 plus a Unisense e for telemetry and a edge lite 50 plus a capacitor bank for a new 380 build myself.

I have the HW60 with the Unisense E and it's a great combo. If you can't use built in ESC telemetry, the Unisense is great except the software is only in German. There is a group in the UK that did a nice job of translating the manual that helps a lot.

Thanks all, great feedback. Been reading the Brain manuals today and noted the pull up resistor requirement, cheers.

Maybe an external BEC is the way to go for peace of mind. Does using HV servos increase or decrease typical current demand?

Any downside to using an external BEC, apart from weight (negligible?) and extra cabling/termination requirements?

Hi there, what's the reason for the cap bank, to dampen transients or to provide a short-term power backup? Just curious, thanks

Does the HW60 - Unisense E work with Brain2-Spektrum 4649t ?

Both but mainly the latter. Had a 450 with the Edge Lite 50a in the past with KST 215mg servos that were too much for it's weak BEC so I added a DC-UP2 and never had another issue. I'm hoping just a single capacitor will be sufficient though if I decide to go the CC route again.

Don't know. Sorry. I'm on OpenTX

Gotcha, thanks. I think I'm going to settle with an Edge lite 50A with CC Bec 2.0, may see how the voltage ripple looks before deciding on the CC cap bank

Now I've pretty much got my heart set on one of these beauties I can't get enough info soon enough lol, I love all the different learning curves and the sheer wealth of info and advice on here is a massive blessing

I thought with the new Brain2 spectrum telemetry/integration and the 4649t it didn't matter the ESC capability as all this data is from the Brain2 unit itself ?

With that esc the esc doesn't send the mah consumed.
The UniSens-E does so the brain doesn't see it, so it can't collect it

.
On a side note the UniSens-E is a great sensor.
I have all the great info of how I crashed this weekend
( Dno it it works with your receiver)
