I'm having problems getting my engine to start.
It's a Jet Central BEE II ks.
Starting procedure
All lines are primed batteries are charged:
I advance the throttle half way then back down to idle
HDT reading:
STARTING....
BURNER ON...
Then immediatley....BATTERY!
My ECU BAttery is a Duralite 7.4 5200mah 2s2p Li-ion. Starting voltage is around 8 volts. I'm currently discarging battery to 7.4 to see if that helps.
My reciever pack is a JR 6 volts 2300 mah.
Any reason why I'm getting BATTERY! Reading while trying to start?
Any help would be greatly appreciated
Tried calling Eric at the office but no answer. I will try agin later
Thanks

Jetset,
Two cell is correct. Dont use 3 cell !! Wondering if low voltage setting is correct in ICS
Give Eric a little time. He'll call you back buddy. He get's a busy as a cat in the sand box at times !
He'll get you going in no time at all. Erics service is second to none. If youre not happy, he's not happy.
You can also post on this thread http://www.rcuniverse.com/forum/forumid_139/tt.htm
Eric monitors that thread dailey and may pick up your question from there.

2 cell Li-Po and it will fire right up.
I have a KS BeeII in my Tucano and we went through the same learning curve. I use a 50C 5000Mha battery, but really...a 30C or so will be fine.

Seriously though,,, I didnt realize the KS series prefered Li-Po type. Good info to know.
Man,,,,,,,,,, Im just a little bit smarter than I was a few moments ago!

Larry,
I received the first KS BeeII Turbo Prop and Eric and I installed (swapped out my non KS) at the Nall last year. We tries about 5 or 6 starts and had exactly what JetSett is describing happen to us. We made about a half a dozen calls to Juan and were pulling our hair out as to why it would not start.
Finally...Juan asked us if the battery had been fully charged, and when we told him it was the one from the other engine (Li-Ion) he said oops! He had us swap it for the included Li-Mag battery that came with the KS unit and blamo...it started.
Live and learn...

That Juan Cat is a pretty smart cookie ![Wink](https://www.rcuniverse.com/forum/images/smilies/wink.gif)
This is interesting stuff though. First thought would tell me a higher C rated battery with higher Mah capacity would be needed with something having the gas start ,ceramic plug on conversion, but not a KS. Good to know as L'll soon be installin the Cheetah KS in the Cougar.
I like my hair too much. Dont wanna be pull'n it out at the field!!!! LOL

Out of interest - what kind of temperature is it when you tried to start? I used a Li-ion on a Falcon a while back and when it was too cold, it couldn't sustain output and caused various flameouts. Back to lipos after that and never looked back.

Li-po's are the only way to fly
especially when dealing with the higher current demands of the KS
p.s. as Larry suggested this post should be moved to the Jet Central manufacturers thread![Wink](https://www.rcuniverse.com/forum/images/smilies/wink.gif)

The problem with Li-Ions is that the internal cell resistance goes up as cell temperature drops reducing the available power.

Well Rich,,,, I really want to beleive what youre saying here. But,,,,,,, I think Boli, myself, and ALL the other guys at First in Flight would feel a lot more comfortable beleiving this IF you provided an 'In Person'' demonstration AT First in Flight 2011!!!! hehehehehehe

What C rating and capacity lipo would you recommend for the KS?
What C rating and capacity lipo would you recommend for the KS?
If you go down in capacity (size) spend a few more dollars and get a higher C rating
![Wink](https://www.rcuniverse.com/forum/images/smilies/wink.gif)
Basically the higher C values means a lower internal cell resistance
If you want to operate longer between re charges then run a higher capacity cell.
I was amazed to find out when I was at FL Jets that Jim Hiller's Rabbit KS only used about 300 mA of ECU power for a seven minute flight which was on par with my Propane start Rabbit.

I verified with production. . .ALL kero start turbines, BeeII, Rabbit, Cheetah, Rhino and Mammoth are supplied with Duralite Li-Manganese 2s2p 7.4 V battery. Please verify you purchased this turbine from Jet Central or one of its authorized dealers. This supplied battery works extremely well. You can expect to charge after 7 flights if and only if it is fully charged at days beginning. The start sequence draws 18 amps for 10 seconds.
If you received a LiIon Duralite battery, Please email picture of battery, and serial number for verification. Upon receipt, I will contact you for resolution.
Under no circumstances use 3 cell battery (greater than 7.4V) with the ECU. Doing so may damage certain components and could void your LTW.
The use of 2s2p LiPo batteries with a 20C or greater rate is OK. . .we suggest 3000Mah or greater for superior performance.
Please email me : [email protected]
Best regards,
Eric Clapp

Received your email. . .I am relieved to hear and know, when you purchased this turbine from a private party, the owner either swapped out or mixed up the battery which came with the system. None the less, you have the incorrect battery and while a good battery, it as others have said, is not the battery for our kero system.
The factory supplied LiManganese battery may be purchased directly from Duralite. Robyn at Duralite is quite familiar with the specifications of the battery, leads and connectors we require. She will indeed be more than happy to take and process your order. Just let her know you are a Jet Central customer.
Again, thank you for the exchange of information which quickly brought your concerns to conclusion and resolve.
Sincerely,
Eric

Yes, I am the second owner of the turbine, and when I received the engine I did notice the battery was not the original supplied battery. I was told by the Seller that it would be sufficient.
A new battery is on it's way
Absolutely awesome service Eric. Thanks very much.

By the way Rich, family reunions are more fun when EVERYONE shows up (at First in flight)!!
Just in case the first spell has wore off I have a double secret spell to hit you with next month!
