Kosmik 200 HV up in smoke

With Stolla on this, even the red "plastic" has a melting point, if the a Jive malfunctions like a Kosmik it would surely melt it and expose components to oxygen and viola bonfire.

Personally I have refrained from buying Kosmik, just too many beta niggles, first there was the card reader/hardware recalls, then firmware updates to address various issues, hell even the cut out for the plugs STILL have not been addressed, paying more than $800 for an ESC I expect, no demand perfection. Will stick to 12S and my VERY TRUSTY Jives for now. 14S with YGE might just be in my future. Rant over, K still has my loyalty for now.

Im sorry to say, but your sounding like my wife.. One of your jives can fail on you as well.All theories like plastics or no air to burn bla bla.. which product didnt had beta niggles?You think yge has a 100% clear list?

Products can fail, people who use them also. If you want to be a 100% sure nothing can happen, stay at home.

This goes nowhere people. There are also thousands with absolutly no probs. And im one of them with a few jives and kosmiks.

All this drama made a point and they are looking at what has cause this so give them some time and respect.All the theories will have absolutely no value unless you have facts.

Of course a Jive can fail. The difference is that the plastic case prevents a fire so the entire model is not destroyed. When I had a Scorpion ESC go up in flames the damage was close to $1k due to the ensuing fire. Had it been a Jive all I would have lost was the ESC.

And you sound like a stuck grammaphone!

To be honest I have send two HJives back to K in Germany because they failed, BUT never did they burn or did the BEC failed, so no damage to my helis, they just shut down the ESC part, why can't the Kosmik do that?

You see, its always the other to blaim.

Instead.. you ever asked yourself if your not the one doing something wrong.

I have 3 jives power and heli. 2 kosmiks and had an 80hv as also a 80 CC and a number of others. No, issues at all.

I saw a guy who killed 3 scorpions and maybe 3 or 4 CC..in maybe a year or so.

What are the changes..

I choose too fly happy not stick with the drama

I think I'm like a lot of people watching this thread. Too scared to comment in case bad-luck comes my way!!

Joking aside I'd be really interested to know how many people have had Kosmik failures when they've setup as-per-manual with the correct fuse in the correct place etc.

Slowly with the accusations here old bullet, maybe you know very little!! You only joined in 2010, me in 2007 when I started with helis, before that planks, from pattern to large scale aerobats, so I assume you want to argue with my experience and knowledge on RC modeling, then do it via PM, the fact is the Kosmik 200 has flaws which the HJ, PJ does not have. My PJives have not skipped a beat since buying my first one when they were released, even with early firmware they NEVER FAILED, not even an error code ever!

But let' do the HF thing FUN, LEARNING, FRIENDSHIP AND MUTUAL RESPECT all to easy to degrade an anonymous user on an open forum.

No worries, ive seen more who are maybe one or 2 year longer in this hobby and there arrogants where just whats keeping them from what this hobby stands for.No intress in any drama communication or pb just tryed to let people stay realistic.

I never accused anyone of anything.

Im out.

Peace!

I thought Christmas would be a celebration of peace..

So, no further use of fire means, please. Let's leave this to the KOSMIK.

Before I forget it: HNY 2014 to all of you!

[TommyBear]

Peace to all.
I have had 3 x jive 120 HV failed on me and had to be sent back to KT.
I've since got rid of all my Jives and HJ and moved to Kosmik on my fleet.
Touch wood, so far so good but I do use a fuse in all of them though.

[bullet3030]

And already a happy 2014 may all of you have a great flying season with plenty of joy and laughter..

She has about 40 flights or less to date and every time she flew flawlessly. esc external temp was always about 45-50 degrees c or so. The motor, pyro 750-50 about 55 degrees. I was on my second lipo when the incident happened. I don't have an sd card installed so cant pull any logs. I don't do any 3D so I am puzzled why this happened. This is my first kosmik esc and I had high expectations from it since my helijives gave me great service. I currently have a helijive in my gobby 770 and she works great with my scorp 4530-450 motor. I sent kontronik an email wanting to know weather I should include the pyro motor when I post the esc. I am really disappointed about this. I see there is quiet a lot of posts about failing kosmiks.

I don't know if someone mentioned this before.....but...

On page 15 of my Kosmik 200HV instruction manual.....it's states in bold print....

to use the fuse.....

And to use the mounting bracket....and NOT use cable ties(straps) to fasten the Kos to your airframe....

Peak aircraft has a nifty CF adapter bracket that has a bolt hole pattern that matches that of the Kos.

I totally agree.
350+ flights on both machines (TDR) both HJ120 and one Pyro700-52 the other the massive 4530-540.
Never did a thing and of course both without buffer pack at 5.6V from ESC's BEC.
