Status: offline 		I got my new superbee 1 week ago and is is a brand new engine.The fuction of I.C.S is more friendly than my previous superbee
and more parameter to adjust.However,when I try to run it ,the engine stop itself for 3 times.The HDT showed"speed low" and the
RPM of stop was about 39000 to 40000.Under my friend suggestion,I use the 7.4V Li-Poly battery.Will the battery cause the stop?When I check the voltage on the HDT,the voltage always keeps above 7.4V even start motor running.Please help me ,thanks!

While we recommend a 6 cell 7.2v nicad or nickle metalhydride battery of at least 1500mAh for the ECU, I fly with Duralite 4000 mAh 4 cell 2s2p 7.4v system. Charge it and go to the flield and fly. That's it. Never use a 4 cell 4.8v pack regardless of the mAH.

"Speed Low" means the RPM simply dropped to the minimum before the temperature did. From what you tell me, the "speed low" reading happened during the ramp process. The turbine had hot reached idle and had not fired the fuel.
Please check that you have the aluminum gas filter and restrictor in the proper location between the solenoid and the turbine. Make sure there are no restrictions in the fuel system. Always re-fill the "gas" before each start. You can email me at jetartessales@aol.com.

Thank you,
Eric Clapp

Status: offline 		Dear Blufox:
Thanks for your answer.The previous stop of engine happened when "running" ,not in the "starting" process.This morning,I start it
again with the Ni-Cd battery involved in the box and eveything is O.K.Maybe the L-Po battery I used is not suitable to the new ECU and
I thick I should use the Ni-Cd battery,isn't it?

Status: offline 		CPS, when the turbine is not running are all the indicators on the display static, no variations? What you are talking about also happened to me in my Super Eagle, when I switched the power on I saw the RPM reading vibrate and the turbine was not running this was due to low voltage on the RX batteries, I used to have power at 5.1 volts. I then switched to 6.0 volts and problems desapeared.

I also use Duralites on my Super Eagle and no problems. I recently finished an F-16 with a Super Bee and I used a Fromeco Lipo battery for the turbine and also no problems.

Status: offline 		Dear Mdurand:
Thanks for your answer.Beacause the previous Li-Po battery is the local distributor made,I thick the "C" number is too large for the I.C.S. of engine.Perhaps not every Li-Po is suitable for the turbine engine,isn't it?

Status: offline 		I heard if I want to use the Li-Po battery for my turbine,I need to adjust the "acceleration" of
I.C.S. because the higher voltage of Li-Po bettery.Is it correct?

If you use a 2 cell Li-Po battery you do not need to make any adjustments to your ECU parameters. Only make sure that on the first run with Li-Po's you move the throttle stick VERY slowly all the way to full throttle. This will make the ECU "learn" the limits.
Hope this helps
Best regards

Status: offline 		are you using fromeco 2600 or 5200 in the turbine.. i need to remove weight from my jet so i think to use a 2600...

Status: offline 		Hello:
We supply as standard, the 2600Mah LiIon battery with our Super Bee turbine system and the 5400 Mah (2s2p) batery pack with the Falcon, Super Eagle and Rhino. Our Turbo Prop system also uses the and is supplied with the 2600Mah LiIon battery pack.

Batteries may be substituted as necessary for weight and balance however, do not under any circumstances change the battery without insuring the battery voltage (ECU) does not exceed 7.4v. For example, a 6cell Nicad pack using sub C cells gives a constant 7.2v however Mah can be as you desire. A 5200 Mah LiIon pack (2s2p) is in appearance 4 cells but functions as a two cell redundant pack. Do not try to go to a 3 cell LiIon or LiPo batery for the ECU. . .you will damage it.

Receiver power (the second side of the ECU power) requirement) should always be 6v to the Rx. This may be a Nicad pack of 5 cells or your choice of LiIon or similar cells. A quality regulator is required if using a battery pack of more than 6v. There are many quality regulators in the market place.

Eric,

I have my Falcon on a bench at the moment waiting for the airframe. I am using a 3000 ma lipo 2S pack for ECU and 4 cell Nicad for rx or 4.8 volts. It seems to run fine. Why do you need 6 volts for rx????

Hey Mav,
The 4.8 volt RX supply often works ok for a lot of installations, however, sometimes the RPM signal can be influenced by interference, a 6.0 volt RX supply "helps" eliminate some of the interference problems associated with hall effect type rpm sensors.

As Eric has mentioned, as long as the maximum voltage requirements are adhered to, there should be no dramas.

So when are you going to bring your Falcon over to my place!!?? They're a great engine with heaps of bang for your buck!

Cheers,
Smithy.
