No.
<simonk> only if it doens't work.

Two cases:
1) WDT is enabled, so it keeps resetting. Turn that off
2) You want BOD to be lower/higher.

I could tell it was reflashed ESCs cuz I couldn't hear the whine

ok im having some issues. the motors keep dropping rpm randomly. i can't tell what's causing the problem. if you look above in the video, when it drops and i recover, that's not me doing that. the throttle is at like 40% the whole time.

also in wind it isnt that great. it was having some trouble and i had to land it in the grass across the street.

the motors drop in uniform, as if i just put the throttle down to 20% and then i put it back to 80% to recover, then back to normal 40%.

Nothing to do with the esc firmware imo, it's the kkb+kkfw+copter+(pilot) setup. For me this a normal behavior for a given setup.

ok i finished cache settings. it works. click "download cache" and it will recursively download all files that end in .hex

check the box that says "use cache" and it will not download anything. it will assume you have firmware file specified in the /debug/ directory

That sounds so quiet, what a difference. I'm jealous, shorts and barefeet. I have too go blow out my driveway, dam snow Watch out you don't chop up your toes too.

Hello,
I am trying to reprogram this ESC:

http://www.hobbyking.com/hobbyking/s...C_3A_UBEC.html

Do not get it to work with the file bs.nfet.hex or with bs.het

When just programmed sounds "beep" does not work.

cheers,

Jose

It can be done ...

Nada, zip.

does anybody know what's different in the current batch of Turnigy Plush 25A ESCs? I had some year old ones, now I got some new ones - look the same, weight is the same, but they beep differently (higher pitched) - so I guess something is different. I'm worried about mixing them on a hexa. Anybody took a look already?

You're talking about the SiLabs ones, I presume? The whole MCU is different and the firmware behaves quite differently. The throttle ramp may be different and so you may have skewing problems at higher and lower speeds. It's kind of fun to try something that people say not to do, though.

I don't see this with anything I fly, but I still need to build a quad (everything has been tri so far). I think some vibration situations can cause the average throttle to be higher while present, and since the vibrations are amplified at the resonant frequencies of the frame, etc., it depends on the current motor speed, and so appear to come and go. I'm not quite sure why this would happen, however, as any oscillation would, in theory, average out to the same as no oscillation unless something (gyros, mixing, throttle response) is non-linear along the way. This is the only theory I have for that at the moment, though.

i balanced my props better and the problem kind of went away. i have narrowed it down to normal behavior recovering from high alpha and wind gust.

before the props would hit mechanical resonance - start shaking at X rpm and it would take a burst of power to push past that, then easy to continue past that point. so every time it hit mechanical resonance frequency it would jump and spaz out

Useful response, as usual. He was asking about clips that clip on to *QFP legs working with MLF package. Yes, you can ghetto up wires to them. No, I don't have that kind of time to waste.
