BLHeli for SiLabs ESCs

[Diogenes]

Ok, I have a stupid question, but here goes.

Just finished building two mxpx v1 HP06 birds, one dbl brushless, one not. Both fly great. I noticed that in this newer version of blheli (9.2) that you dont have access to the percentage slider to change the rpm of the motor like in earlier versions.

However, in the top part of the screen, if you reduce the number of teeth on the main gear, the percentage/rpm goes up. Is this the way to do it now, or is this just merely a calculation on screen and it has no effect. Note that i am using 8t pinions on both at this time.

The slider is only applicable to Gov Setup mode and has always been. The newest version of BLHeliSetup just makes it more obvious.

So, if calibration finds 255 as max, 250 will be stored. If setting max with BLHeliSetup, it should work well to set a value above 250. Which can extend your range a little bit, from 2000 to 2020 .

Excellent! Just tried it out by saving my current setting to file and edit the file manually. Now PPM min/max is perfect just like before where my 8000kV hp08s tops out at 96% not 92%. BTW, that's 5600rpm with 10T on the 130X and 7800rpm with 8T on the mCPx.

Thanks,

Read the TX programming manual from "github" linked to in the 1st post.

I have a question, I'm a newbe to HF forum and hope this is the right thread.
I have a 3in1 that i believe has a bad tail FET.. Everything works on my mcpx except the tail motor just spins real slow after i plug in the battery. Is this board a good candidate for a double brushless mod with a flashed xp3a/hpo3t for the tail? Will I need to remove the FET or can I just solder the signal wire at the point I believe is called an mcu or gate and be done. btw it's a v1 3in1.

Basically all the info in the ".inc" file needs to be entered. Which pin of the MCU goes to which FET with which polarity and so on. Also there are some parameters for ADC voltage level and timing of the fet switching.

@ Sskaug :

Did you see some magic smoke or not yet ??
I'm exciting to test the new ESC Opto !

Let me know when it's ready for action
Thank you

Well, I would suggest to remove the FET; it's damaged and removing is not that difficult.
But it is not very likely that it would otherwise result in a noticeable higher power consumption.

Thanks 4712 will do some surgery and build my mild bl bird (thinking an hp05s/xp7a and hp02t/xp3a)... My next question would be about gov Tx mode vs. gov arm on what i consider my wild bl bird (hp06s/xp12a hp03t/xp3a). If i'm not getting any tbo with gov tx mode is there any benefit with setting up gov arm mode. I don't need to change desired headspeed too often.

if you need more about this, read on here, look for tail-mix, gov-arm... everthing is nicely explained in the first post

ok, got it figured out. Set my percentages to 80%. Question. For main governor mode, do I put it back to TX (0) or leave it on Setup (2) after selecting where I want it governed at? I'm assuming I put it back on GOV TX mode for now, correct?

[DoubleCH]

The percentage number is stored in the ESC for Gov Setup mode to use. If you run Gov TX mode, real-time throttle is used. It's stated in the manual. Or read my thread.

How can I turn of the governor of my flashed esc without a toolstick? I'm using a XP7A and a C05M 8t, which bogs very easily, slow response to pitch pumps too. I hope running a flat 100 without governor will make it a bit more fun?

Go ahead and set a flat 100, at that point the governor has no effect. No need to change settings.

Ok thx. I also ordered a usb toolstick. Does anyone have the correct settings for the co5m motor? I think mine are wrong because i feel like it was more powerful brushed then bl. I soldered everything directly except the motor. And switched to micro deans, but no difference.. So until now i'm quite dissapointed with my bl conversion..

Not sure what exactly do you mean by slow response to pitch pump. My guess is you either have a non-flat throttle curve (no-no for Gov TX mode) or you set too low a flat throttle curve (throttle value does NOT correspond to amount of throttle). If it's still less powerful than stock with 100% flat throttle curve, make sure your motor cover is not touching anything.

[ntotheo]

I always use flat TC's, I started with 50-55% flat in tx governor mode, then 60, 65.. I also tried 100%. When flying around 55% throttle, it only bogs when pumping the pitch really hard (on 70% pitch), and also has +- 100gr constant thrust on a good battery. The problem is, the time it takes to get to that amount of thrust, when pumping the pitch and keeping it on max, I get arount 70-80gr of thrust and it slowly goes up to 100, max 110. Thats what I mean by slow response :p. Don't know if its normal.. Maybe I'll just have to throw te c05 away, forget about mild bl and put a HP05s-HP06s in? (don't know what the best - most powerfull - motor is to use with an xp7A?)

[DoubleCH]

Definitely not normal with a flat throttle curve and sounds like a non-flat throttle curve to me. You should get max thrust instantly when you give full collective and then headspeed drops together with max thrust. There's nothing for the governor to increase HS (not throttle) on high collective. Governor of course needs to increase throttle on high collective when that drags down HS, but max thrust is always the instant you have full collective.

Could it be my batteries? On the stockers I get 80grs immediately. And I have one left from Beez2B which gives me 110grs, governored on 55%. But they start out a little lower and work their way up to 110grs.. Could be my scale too ofc.. All the other ones are 560mah's 45c's which only give me about 70grs. (they were stored like 2months fully charged, totaled my previous mcpx under a car.)

Anyway, I ordered myself a HP06V2. But I'm going to test her again in a big gym room later this day on a flat 100%, last time I flew her was in the snow with some wind..

Thanks for your replies btw

No magic smoke, and quite simple. Although the pcb layout is very different, the MCU signal mapping is the same as the Plush 40A esc.
So, for the HW Flyfun 40A opto, just use the Plush 40A code

For your reference, this was not BLHeli. Just 100% flat curve.
