Is it possible to flash the Hobbywing 50A ESC with BLHeli?

It's this one: http://www.hobbywing.com/product_show.asp?id=307

thanks

Thanks for the hint. Now ordered

steffen, I am very new here, but have been using blheli for almost two months now. i just wanted to say thank you. all of our rigs have been flashed to version 11. our flat octo has never flown better, and the 80amp plush esc's on our U7 setup give it awesome response even with 18inch props in a coax config. i am currently looking at the hobbywing 120amp hv platinum esc's on my desk here, will the turnigy 120amp hv v2 code work on them?

thanks again.

Thanks! I use the HW 120A in my Logo 600 heli and it runs very well. Others have used BLHeli on that ESC too. There are two versions of this ESC, compare with the pics in the supported esc doc.

I'm a bit confused with the set-up for the governor.

So, i'd like a head speed of 3150.

I used the BLheli integrated calculator, and set:

Lipo 3
motor 3600
pole 6
pinion 15T
main 150T
comp 81

I've set the gov range to Middle

I've moved the slider up and down until the RPM=3145, next to this is THR=83%

Does that mean i need to set my throttle curve to flat 83% in my TX?

The motor=86%, does that mean the motor will be at 86% when the RPM is 3145 ?
Is 86% low enough to allow the governor to govern?
What are the recommended headroom on this?

Hi Steffen,
the ESC freakystylez linked is also available as 100A version and looks really good.

I wanted to ask if this ESC will also be added to BLHeli?
Soft and hardware actually looks good but no TX governor is a big disadvantage for me.

Other questions are:
will BLHeli still be a good choice for the new ESC generation? Like the MCU is now faster ..
How will BLheli handle choosable BEC voltage, rpm output, and the seriell data output?

I mean will there any bigger changes at Blheli required/possible ?

What are your plans with Blheli at all? Will you still continue and support it?
Your the only author I believe?

Although BLheli now exists quite a time mostly to tune micros form the beginn, it still has a lot of potential.
The State of the Art makes it still the first choice up to my biggest heli.

How do you think the future will look like?

best regards

That's a lot of questions .

It'll be interesting to take a look at the new HW 50A ESC and it's claimed 50MHz MCU. Then I guess we'll take it from there. Maybe that can give some benefits, maybe not.

It also depends on flash size - currently the 8k is quite full...
Selectable bec voltage should be easy, rpm or serial output will require more code space/effort.

My plan is to stay in this as long as it's fun . And the code is open source, so it's always possible for others to contribute or branch off. Lately I have spent quite a lot of effort on the multi part of the code, making it run in sync for high pole count high kV motors on high voltages. That will be a very important improvement in the next rev.

Apart from that I don't think there are much plans. What would be most desirable for the future?

Thanks,
Steffen

steffen thanks for your reply. i got the version 2 esc from hobbywing. i am very impressed with the construction overall. I will actually be using 8 of these on my next heavy lift build. they will be powering t-motor U11s. i really hope they are up to the task, these U11s look pretty power hungry. i was also looking at the 150 amp lower voltage version of this esc for one of our smaller multis. do you have any idea if the 120 code will work? also i am curious, does removing unnecessary code allow the mcu to run more efficiently/better?

thanks

[sskaug]

Wow, an octo with U11, that's really huge .
About the 150A LV, the 120A HV code may or may not work, that's impossible to say. without looking at it. If you want to I can get one and map it.
Generally, removing code will not improve running, as unused code is not executed (like when governor is off, that code is not run). Also much of the code executes while waiting for the motor to rotate.
Of course some improvements can be done by simplifying functionality (like less programming and support of fewer ESCs), but I think the improvement would be hardly noticeable in a normal operating environment.

steffen, thanks for the info. would you mind if i pm'd you. i am working on some things i would rather not discuss in public.

Steffen- Can you confirm if I've understood this or not please buddy?

[xJoe]

Also, i bought a plush 40A esc and it is pictured in the "supported esc's" pdf as a "Hobbywing Platinum Pro 40A". BLHeli 11201

Is this the same ESC?

This looks correct to me. Achim would be the best to comment on the calculator. The headroom that is required from the motor will vary with setup and flying style. If the motor bogs when loaded, you may increase pinion, but generally at some point battery capability and motor efficiency will limit you.

I think there is a mix between brands and types here. If you choose the ESC type that matches the picture, you should be ok.

Not much to comment on
The calculator assumes that 15% headroom is a good value (Value is shown in green then), but this should be seen more theoretically. The practically needed headroom depends on the the hardware combination, as Steffen already wrote.

[xJoe]

Thanks for the clarification. I'll give it a try :-)

[apper001]

As possible? BLHeli development: maybe data logging with some added parts on the ESC?

Or datalogging (am really going overboard now...) in combination with a "beaglebone black" and arducopter....

[xJoe]

Back to gov mode again... Sorry!

As an example, lets say my motor/gears require a throttle of 85% to acheive the desiged head speed. So in idle up I set up a flat throttle curve for 85%.

The ESC will govern the head speed for me in this case, right?

Then , in normal mode, i have a 0 to 100% linear curve. When i get to 85% throttle, does the esc switch to governed mode after say 10 secs or something?

How does the esc know when it is linear motor control or if it should start governing ?

Yes, but this is only valid for "Governor Mode" = "TX"

if "Governor Mode" = "TX" BLHeli will start govern the rpm from throttle >20%. A " 0 to 100% linear curve" would not make much sense with enabled Governor Mode.

Hi stefan,
i completed the XP-3A upgrade today , flashed with BHELI 11.2.0.7 , tried 2 motors , when i throttle up motor gives no response , no beeps , attaching pics also , kindly advise.

also set both gains to 2.00, everything else default, flat throttle curves . but no motor response , what to do , kindly help

Replying and referring here in addition to the PM and Img you send :
Be sure to set "Input Polarity" to "negative"!
Maybe you should have a look at Dylan's page here.
