Well I don't know about anyone else, but I've had a shitehouse day... Went to update my KOSMIK 200 with the latest firmware so that I could change the BEC voltage and now she's bricked.
Okay then. I've prefixed this thread as 'Info', so I shall explain WTF happened. I'm in a bit of a story telling mood, so if you just want the cold hard facts without any if the dribble then proceed to the last paragraph in this post. Please also note that this really only applies to old KOSMIKS from the first batch with V2.6 firmware (possibly 3.0 as well). My Kosmiks serial no. is 00131.
Background (for dramatic effect): I bought the Kosmik second hand last year and had been flying it quite happily with stock settings in Mode 4. I then decided to change the BEC voltage up to 8V so that I could run a 2S Lipo buffer pack and with that I bought a second hand ProgDISK. I didn't get around to using the Progdisk for a few months and when the time come to sit down and have a tinker the Progdisk up and shiz the bed! Fark... I thought there goes a hundred bucks! Fark... Fark... fracking Fark!!
Anyway I sent the Progdisk back to the mother ship in Germany and they told me it was rooted and that they didn't make them any more and that I had to buy a ProgUNIT albeit at a discounted rate, phew! Long story short - Sent money, received Progunit, all good now, happy days! BTW all this hoo-ha with the Progdisk was in about November last year.
Jump forward to this past week: So I haven't been flying much since December 2014 and had not had the E7SE in the air at all in that time let alone connected the buffer pack and changed the BEC voltage like I had planned. I pulled her out of the shed last week and have since put about a dozen flights in and am starting to get my mojo back.
Last night I decided to fire up the Progunit to change the BEC voltage and have a squiz at what else is in the settings. Due to the older firmware I wasn't able to get the K-KONFIG software to open up the parameters for me to change them so I decided I needed to update the firmware. I read through the software download page on the Kontronik website and could see no reason why the update would not work for my ESC. I downloaded and ran the 4.5.1 update and everything went smoothly. After the update I was able to edit all of the parameters in the K-Konfig software and I was happy. That was until I went to power up the ESC to reprogram Mode 1 and Mode 4 and there was no fracking beeps from the ESC. (Insert more profanities here) I checked the log and it was saying that it was 'Wating for a signal'.
I jumped online and had a look around and could not find anything obvious, so I decided to re-flash the firmware. Same events transpired, flash worked fine, software config was functioning, but no bloody beeps.
After some more stuffing around trying different things I finally had enough and emailed Kontronik explaining my predicament and went to bed.
Today: Received an email from Thomas, whom I also dealt with when my Progdisk died, explaining that I had to send the ESC back to Germany for repair as they could not perform a long distance diagnosis. I was a little perplexed that they would not even try to help me via email, so tonight I did some more research and found out that apparently the first batch of Kosmiks had a hardware issue that could only be fixed by sending them back and for whatever reason this hardware issue prevents successful upgrading of the firmware. So after all of that I can't fly the E7SE any more until I get the Kosmik repaired.
I'm a little peeved that there was no disclaimer with the firmware release indicating to check the current firmware and confirm that it would work. I tell you that they better bloody well not expect me to pay for this... Steam my appear from my ears if they do!
On a lighter note, in the hope of a short term solution I did send Hobby Wing a cheeky email asking them if they needed anyone in Australia to beta test their soon to be released 160, but alas I have not heard back from them. Oh well you don't no if you never ask.
In summary: If your KOSMIK is a first batch model with V2.6 firmware do not update the firmware until it has been updated/modded by Kontronik first or that shite aint gonna work no more!
