Anyone running the new Schulze 40.160WK Future XL Controllers?

Grrrr i wana see this thing go!!
I can imagine your frustration

Hope you get it sorted soon mate.

Tried a bunch of different tests last night changing parameters, but still no luck.

I tried changing:
timing
accel ramp
Softstart
cut-off voltages,
brakes enabled/disabled
reverse enabled/disabled

The same problem still exists. I am afraid of frying the esc if something if some variable is off too much.

I'll have to try using several different motors on the bench test to see if this helps. Schulze has been helping me troubleshoot the contorller, but we have not found any conclusive reason.

The data off the esc is coming out very erratic which also concerns me.

Which transmitter are you using ?
Which mode : PPM or HRS ??

Futaba 3PKS with 2.4GHz module. I tried switching from HRS to PPM wih no change in performance.

Throttle is in reverse mode now ?
Does the tx beep at No throttle and Fullthrottle ?

[Xcesive8]

Pretty sure the Schultz controller only works on PPM mode, think i even read that in the manual.

But why dont you send it back?
Has schultz said they'll work with you to fix the problem first and if not send it to them?

[RaceMechaniX]

I believe so, but I did not think to check wether the throttle is reversed. Currently if I pull the trigger it spins in the correct direction. If I push the trigger backwards nothing happens. I would assume its correct then.

The 40.160 beeps once after the tones, but does not beep at full throttle.

I asked I-Care the same thing before I purchased and they said 2.4GHz is no problem. The manual does state that HRS mode is OK.

I would rather try and diagnose the problem on the bench before sending it back if possible. If I do need to send it back I'll probably want to send the motor too so they can recreate the conditions.

HRS might NOT work.
Stick to PPM
Check your tx for the throttle. probably must be in reverse mode.

I tried PPM with the 2.4 R602FS reciever, no difference. I'll try an older PCM reciever when I get home.

Pull out the esc from the rx.
put a servo with servoarm in the same channel on the rx.
How does the servo react when you push/pull the throttle ?
Does it move in the right way, with full range ?

[RaceMechaniX]

I'll check later tonight. Thanks for the good check. Could be a be bum reciever. I actually had a R603FS fail last weekend on the throttle channel, but its was quite warm out.

Updates! video added

Last night I checked several more variations to see if I could find the culprit.

First, I put a normal servo on Channel 2 and checked that there were no issues. None were found. Just to make absolutely sure I used a scope and checked the output of the receiver. It looks perfect, so the receiver radio are not the issue.

Next, instead of using the receiver to plug into the Schulze I used a Hitec servo checker which generates the correct output to replicate a radio. Same stuttering problem as with the receiver so it's not a case of throttle input signal.

After checking the input line I changed motors. First I tried a 4-pole Neu 1509 2D, same problem. Next a 2 pole Castle Mamba motor. Same exact problem.

To make sure all the motors were working fine I hooked up a Castle HV110 using the Servo checker and made sure all the motors were operating OK. Sure enough all the motors work fine.


So now the controller arms fine, but as soon as you give it a little throttle it tries to spin, but after a 1/8 of a turn it stops and rearms itself like it lost power. I took a quick video with my camera to show what is happening.

Man you truely deserve a new controller.
It looks to me that you have tried everything!
I applaud your effort and persistence, i would not have that much patience.

In your video, i cant believe it starts up, arms and then you put a lil throttle down it starts up again and arms. Bizzare

Send it back, or do you know anyone with a schultz you can borrow to do a test.
That way you will know for sure it is faulty, and do a video of the same thing you just did, but swap the contollers over in the same vid and show em it works.
Forward the link to schultz

I found the problem! After several back and forth emails with Shulze, all the indications said it was something in the voltage supply causing the problems. All the connections and batteries were good, but Shulze suggested I check the leads to the caps and there was the smoking gun or should I said the vaporized leads.

What I believe happened is the first time I powered up the Schulze at the lake I did not use a soft start resistor to charge the additional ETTI caps. Of course there was big flash, but what I probably did not notice was the leads to the on-board caps vaporizing.

So let my mistake be a future warning: Use a Soft Start resistor to charge any HV controller with or without external caps.
