Need firmware for Maytech ESC!


(New to the forum and first post! )

I am looking for the right firmware for Maytech Multicopter 45A Opto 2-6S SimonK ESCs that works with Tiger Motor MN4014-9 400KV. I have read that these motors can have stuttering problems with the SimonK Maytech-ESCs. The Maytech support told me that I can reprogram them with BL Heli-firmware or send them in. Well, I cant find the firmware and Maytech support dont answer anymore. Are there a better firmware?

Anyone here have any experience with Maytech and Tiger Motors? And programming them? What USB-programmer and program can be used? I dont even got the refresh-rate from Maytech support. Are they 50Hz? 400? 490?

Need to get a Vulcan 900 in the air.

No one uses Maytech ESCs and know how to reprogram them with other firmware?

I used to have the Maytech 30A's. They are the same as hobbyking blueseries 30A. You need an atmel socket tool to program the ESCs with BLHeli firmware. I used mine with Tmotor 2216's and the work great. You can find videos on how to flash atmel ESCs with BLHeli in youtube.

here's one:

BLHeli Suite works great, I have connected my Afro USB Programmer to the Maytech-ESC as shown in the video. But there is no Maytech-firmware or BlueSeries 45A (I have 45A ESCs). But, I can choose to use another .hex-file, if I could find one for this ESC. I cant get them from MayTech, they refuse to answer.

Anyone? No one uses MayTech? Anyone know another Maytech-support than what the manufacturer have on their homepage? I got in contact with them a long time ago. They said I could reprogram them with BLHeli or send the ESCs to them. I asked for firmware and they answered on that mail ... asking if I have sent the ESCs to them. I asked for firmware again. After that I havent heard anything. ESCs are in place on the 900mm multicopter but it is useless...

That would be awesome! Spring is coming and we have starting to find another ESCs if the expensive Maytech seems to be useless. But its hard finding ESCs for those Tiger Motors. Dont like reading "may stutter" in the Maytech-manual... That means "will probably dive". Thats not good at 7 kg's. Only thing missing is the BLHeli-firmware (.hex-file) for the ESCs.

I am not that used to different programs used to program ESCs. The list of firmwares they have, do they differ between different programs, or do they all have gotten the same firmwares from all the vendors?

TeeSCee (also from Finland :-)... you said MayTech are the same as HobbyKing BlueSeries (huge difference in price). Are there any 45A OPTO BlueSeries? Is it the same hardware, but maytech uses another firmware?
