@dreamfly
Sir closeup video of quad or esc flashing?
@Satya bro try to calibrate individually and then together with kk2.0. They should work.
If they don't try that trick. Connect all escs to the board and put throttle stick to the max. Power up the board by pressing and holding buttons 1 and 4. You will enter into programming board. First 4 beeps are for throttle range calibration. After 4th beep immediately bring the stick down. It should work for you. We both have same escs and it worked for me both time with non-flashed and flashed escs.

@Dharmik bro i will try that and let you know... I will flash my ESC as well, can you tell me from where did you got those wires/plugs from? (AVR to ESC)

@dreamfly
Sure sir. I will post video soon.
@Satya bro that's diy homemade USBASP to ESC wires and pin. It requires to connect 6 usbasp pins to the ESC.
MISO, MOSI, SCK, GND, VCC, RST
Actually flashing takes just 4-5 seconds but hard part is to select firmware, making that pin at home and proper contact to the pads while flashing(you can solder wire directly). After flashing 2 escs it started showing error for rest two escs. I had to scratch those pads on esc gently and then it went smoothly.

satyagupta

hmmm so soldering and flashing would be better idea?? what do you suggest??

Yeah bro soldering is reliable but you have to be very precise because there's only 1 or 2mm gap between pads. If you need i can send you my diy pin.

satyagupta

Are so generous of you bro, but i dont think without trying i should trouble you. Let me first try it out, and bro about soldering i have been doing that from a long time so i dont think it would be a problem for me but still i would take your advice and keep soldering as last option. While writing this i rem one thing, my very first order from HK instead of MALE TO MALE 10 CM connectors i bought MAKE TO FEMALE (servo extensions) now i can make good use of it :giggle:

Sure bro. Have you tested it with non-flashed esc?

satyagupta

Yes i have not yet flashed my esc, current situation that i explained to you is with the non flashed ESC. You recommend to flash my ESC??

Satya bro flashed escs would sure make difference but if your quad flies well you can continue with non flashed esc. I couldn't test my quad yesterday as i was out of town. If you really want to flash then you need to flash bs_nfet.hex for hk f-20a escs.

here are pic of my crashed quad.  Have rebuilt it though.  Waiting for some props.  This Quad has drawn first blood! :(

satyagupta

@dharmik Have not been able to fly with the non flashed ESC was busy last week. Will try this week end, can you send me that hex file please..

@dreamfly are you using flashed ESC or non flashed ESC??

I fly with  the normal Turnigy Plush esc's  They are OK.  I have ordered some flashed esc's. Will have to check the WoW factor or those.

Satya Bhai,  which controller do you fly with?

I read that plush ESCs are not suited for multirotors. It was well-discussed on many threads on RCG (esp. on the simonK's f/w flashing thread) that plush'es make a whine at 8Khz (or 16?), well, I don't know what it really means, but that's undesirable.
Many said the hobbyking F-20 or F-30 or F-40s (with light-blue heat shrink) flashed with SimonK outperform the Plush ESCs and even the Maytech ESCs of montorc.
F-20, F-30 and F-40 are WAY CHEAPER than the plush.
Anyone tried them?

satyagupta

Dharmik and me we both are using F-20

Dharmik have flashed but i haven't yet

Yeah Satya bro that's F-20A. Check product id on that page. And there's no surprise that both F-20A and F-30A are now on backorder.

The Turnigy esc's are for sure not built for multirotors because of their smoother throttle response more suitable for planes (multirotors are pretty new inventions).  So we'll have to wait and see how the Esc manufactureres respond to this new gen hobby and how?

Hello,

Greetings...

I am a newbie to this field... And I intend to make a Quad for which I have purchased the materials... Also I am ready with the assembly... The place where I am stuck is the Programming... I have HobbyKing Multi-Rotor Control Board V3.0 (Atmega328 PA) and Seriously I have no clue what to do with that....

Specs:
1.   HobbyKing Multi-Rotor Control Board V3.0 (Atmega328 PA)               x 1
2.   Turnigy D2830-11 1000kv Brushless Motor                                     x 4
3.   HobbyKing 30A BlueSeries Brushless Speed Controller                       x 4
4.   Hk X550 Frame                                                                         x 1
5.   Fly Sky 6 Channel Tx n Rx

Thankyou...

Hey Adiboy,

You will need a programmer to program hk board, something like this

Here is a video about programming the same
