    Anyone familiar with SimonK ESC code?

    Not sure what to think of this, probably because I just don't have sufficient knowledge about the topic, but when I look at the video, I am impressed about the difference in what appears to be the response speed of the ESC.

    I'm sure someone on here has tried it, it's been around for a while now. It's great for response time but consumes a little more current and thus leads to shorter flight times. Regardless, for an acrobatic type quad, reflashing the ESCs seems almost mandatory.

    Flashed 4 Turnigy Plush 30A's last weekend. It went relatively well. Didn't have the time to fly with it yet.
    Note that if you buy these ESC's today, they'll have a Silabs CPU which aren't flashable. Mine are about a year old so they still had a ATMega.

    Very interesting. I've got five of the old Turnigy Plush 25A's, so I might give it a go and reflash them. Of course, I'd then have to go and mark them special so I don't mix them up

    Actually it's the opposite. For a stable quad in the wind, reflashed esc's are a big help. The also pretty much get rid of the wobble of death on descent. The faster response time can allow the use of higher P values as well.

    I run stock HK SS esc's on my acro quad no problem. You don't need fast response time for a acro quad, just brute power. The P term is usually lower, so oscillations don't show up as much.

    Well, I cut open one of the new ESC's I've got, and it turns out they the SiL type So I've put all five of my spares up on eBay for sale. Ordered some new F-30's, which apparently have an Atmel and an external oscillator so are supposed to be great with SimonK firmware.

    My original four in my existing quad are probably Atmel, but I'm not going to cut them open until I have spares on hand

    Hi

    I had problems with the speed of the ESC, the flight controller could not be adjusted. I also have ESC clone, and was programmed without any problem.
    Let's say this was not my first AVR program
    What is it? Required for all controllers, it would be. Slightly higher power consumption, but the quality, speed, power 1000 times better.
    Now I would normally have to produce all possible PID, and just enjoy the flight. I also noticed that when the bearing failed engine stalling!

    Got my new F-30's, and they're all Atmel. Reprogrammed them with SimonK firmware tonight and ran them on a test motor to verify they actually work. I haven't put them in a quad yet, but I'm planning on pulling out my existing (old) Turnigy Plush 25A's and flashing them too, once I get some heatshrink for them. I'll report back how it went
