Dharmik bro post some pictures of flashing of ESC please am planning to flash mine too...

Satya bro step by step tutorial up next. I flashed one damaged esc today. I flashed it again again 4-5 times, without bootloader and with bootloader enable and it went smoothly so i have decided to flash actual escs that i have on my quad right now. Flashed esc makes different voice while connecting with battery.

ya i have seen the video about the sound of the FLASHED ESC.. eagerly waiting for the tut...

Dharmik Bhai,  Is there a real real benefit from flashing to simon code?  How do you actually measure the benefit?  Is it much easier to control?  Just wanted to know.  I have just rebuilt my quad after that disaster 2 weeks ago.  Did a test flight in-house and all seems fine.  Just wanted to know if updating the Escs' really make a world of a difference or is it just a 10% increase in performance.

@dreamfly
Sir nice to hear from you that your quad is repaired. At this moment i can't say actual benefit and difference because test flight is yet to be done but Ashta sir has flashed ESCs and posted video of his quad. Today i flashed 5 ESCs and all went smoothly, tested them on bench with 1700kV motors it works fine. I will now test them on quad soon.

Is there anyone in india who's used I2C ESCs? The ESCs we use have a low refresh rate (400Hz?), and HK's SS series are worse, but I2C ESCs have a refresh rate of upto a KHz. Someone using an MK must be familiar.

Vineet i heard about wii esc firmware. I also heard about i2c modification on rcg topic. I don't think anyone selling such escs. Simonk firmware also has high refresh rate.

Dharmik Bhai,  what are the tools used to flash the esc.  I am aware that we cannot flash the Turnigy plush using silab chip. 

Sir i am using USBASP cable and homemade connector. I am going to attach some pics i took recently.

Thanks Dharmik Bhai,  Just 2 more question:
1. is this Esc flashable?

2. If it's not too much of a hastle,would you be able to help me flash my esc's if I purchased them and sent them to you.  I don't think I would have the patience to go thru all this.  I dont mind paying for your services.
or the other option is for you to help me build one of these gadgets you have built to flash the Esc's

Here I am waiting for (more) videos that compare sans-simonK f/w and reflashed with simonK f/w ESCs. I just am not understanding what big practical difference can be caused.
Thanks,
Vineet

Sure sir. In fact F-20A and F-30A are sisters. They both have programming pads at same place. Click on front and back "links" they both have same. Please have a look at this list

Before you invest your money for those escs please wait for Astha sir's Review i will also post mine too because once ESC flashed we can't UNDO.

one more thing is there are no low voltage protection(requires additional alarm) and temp control in this simonk firmware.

Yeah bro, i was confused whether to flash my escs or not. I read somewhere that KK2.0 and more advanced boards need low gains to work with non-flashed escs and i found it true as i had to reduce my gain way below 40-50. Flashed escs can take high gains easily without wobble.
here is that post

Dharmik bro, am again in problem today i tested my quad at home (with these rains i am not able to take it out to test) motor 2 and 4 stopped abruptly. Motor 2 continues to spin but motor 4 stops.

i could not test much as mom and wife started shouting but i am kind of curios why is this happening again??? any trouble shooting steps?

Satya bro what's your tx End Points settings?

End Points settings  i know you did told me about this earlier but i forgot can you tell me once again how to adjust to set that?? please

Hmm, I don't know what 'gain' means. Is it somewhat synonoymous to PID values (as in multiwii)?
Thanks,

vineet

OMG! THE ULTIMATE PROOF:

I also posted in the f/w re-flashing thread.

Yesterday i tested my quad with simonk flashed ESCs and i see huge improvement in stability. Now it doesn't oscillates even after increasing P gain to 80-100%. I have also changed props as admin SLS said and now using 8x4.5 gemfan props. props and flashed escs together makes quad more stable, better than previous HK board. I am still finding best gain settings, i will test further later and try to get it on video.

@Satya bro
I mean EPA settings in your tx configurations. Which tx you are using. Once i had such issue but after changing EPA to 120 and calibrating again it resolved.
@Vineet bro
Sorry yeah it's PID values.

Good to know  
BTW two question for you
1. You are using kk2.0 board right? Dont think the P gain values are in percent. They go higher than 100. Please correct if I am wrong.
2. Which mode you are running + or X

Thanks

So Dharmik Bhai, you seem to be very happy with your simon flashed esc

Bro this is my tx http://www.hobbyking.com/hobbyking/store/__16238__HobbyKing_HK6S_2_4Ghz_FHSS_6Ch_Tx_Rx_Mode_1_.html

@raja mastana
Yeah sir my mistake, they are not in percent. I am flying in X mode now.
@dreamfly
Yeah sir better than stock firmware. problem is i don't have open space where i can test my quad freely. Only rooftop left, I keep it as much low as i can near to the ground.
@Satya bro is that TX programmable?

No idea how do we know that???

Satya, looks like that radio is not programmable. Only servo reversing features is available.
