e-Electric Motors & Controllers > Jeti 08-3p Master Heli Question

I purchased a Jeti Master Heli 08-3p at the last Toldeo show (to drive a Hacker B20-22S), and have had problems with its setup. I had to download documentation off the Web because Hacker didn't have hardcopy when they sold me the controller.

The setup tones from the controller don't fully match the documentation. The documentation says the first major item for setup is timing, and that does match the documentation. However, the controller moves on to the next setup round and I can't match what I hear with anything in the documentation. The second round in the setup goes something like this:

dash (repeats four times)
dash dot (repeats four times)
dash dot dot (repeats four times)
dash dot dot dot (repeats four times)
After this, the controller goes back to timing setup.

Can anybody point me to correct documentation or explain this sequence?

I think you are either slightly confused or your controller is faulty. There is always 5x repeat for each signal. I agree that this "beep" system is very bad and confusing regardless whether controller is good or bad. Also documentation is not the best I've seen I had similar problem with break in 40-3p to catch the right time and beeps. Sometimes it is also tricky because trottle stick in your transmitter may be reversed? and then up is down and vice versa

Try this extract from original document to somehow catch the beeps

HELI controller
· The very first setting of the Heli controller
o Full throttle
o Transmitter on
o Receive on
o Wait until 4 “bleeps” ( · · - · )
o Throttle stick back in motor off position
o One “beep” => Mode 1: Normal control
o Two “beeps” => Mode 2: Constant speed (RPM control)
o If you want to change the mode, disconnect the motor battery pack. Repeat the procedure.


· How to change the Timing Mode:
o Switch “on” the transmitter and move the stick to “full throttle”
o Connect the main power pack and turn on the receiver switch (if used)
o Wait 5 seconds, you will hear 4 beeps ( · · - · )
o Wait next 5 seconds
o You will hear a 5 time single “beep” – mode 1 ( · , · , · , · , · )
o 5 time two “beeps” – mode 2 ( ·· , ·· , ·· , ·· , ·· )
o 5 time three “beeps” – mode 3 ( ··· , ··· , ··· , ··· , ··· )
o 5 time four “beeps” – mode 4 ( ···· , ···· , ···· , ···· , ···· )
o Set the Timing mode by moving the throttle stick to position “close”, while between the 1st and 5th “beeps” of the desired Timing mode.
o Configuration of New timing mode, single “beep” (if you had brake on), double “beeps” (if you had brake off)
o The timing mode is now memorized, that means it will not change after disconnecting the motor battery pack.
o If you want to change the timing mode again, disconnect the motor battery pack. Repeat the procedure.


Cut off settings follow timing mode settings. Therefore when you want to change only cut-off mode do the same procdeure as with timing mode but wait until last timing mode beeps and then cut off mode beeps starts:
o Cut off mode 1 – (min. 4 V), “long tone” – NiCd/NiMh ( - , - , - , - , - )
o Cut off mode 2 – (constant 5,3V), “tone + beep” – 2 Lithium cells ( - · , - · , - · , - · , - · )
o Cut off mode 3 – (constant 7,95 V), two “beeps” – 3 Lithium cells ( · · , · · , · · , · · , · · )
o Set cut off mode by moving the throttle stick to position “close”, while between the 1st and 5th “beeps” of the desired cut off mode.

good luck!

Thanks for the reply. I have the documentation you included.

I'm well past the "reversed throttle" setting problem. If the throttle is set incorrectly, and you try high throttle for the settings, then you get a normal start and don't get the setup beep sequences.

I tried listening to the sequences again, and can't really tell that the cutoff sequence matches. The governor mode and timing mode settings do match. I strap the model (Hornet) to a desk writing pull-out, then put my head inside the rotor disk to listen to the tones. I really don't like doing that.

I have set the battery cutoff by guessing at the relative position in the sequence. I'll have to try the model a few times and see if it kills a Lithium-polymer pack.

BTW: I guess I should have posted the text as "repeats four **more** times".
