OFF is the learning NP only and ON is fixed travel.

Thanks
I got mine set to learning NP. fixed travel is mandatory for Futaba HRS and only version 3 controllers will work.

Default Need some help!!!

Just got my uforce 75 and hacker 6. First time using it - on probably the second run - I hit the boards and broke my front upright - but I realize I coudln't get power.

turn out that some is jacked about my hacker 6. I can literally hold the pinion in my hand at full throttle and it would stutter and not able to turn through. At no load it sounds fine but slow....what did I do?

Is the controller still arming every time the batteries are connected? I can only suggest to check the soldering joint in the motor to ESC and also check your radio trims are in default position (throttle setting in your radio should be in reverse position)

Heh...I don't remember..i'll have to check. Does it matter? Could it be that I need to reset the u-force 75. I refuse to believe that I have broken my hacker 6 under like 4-5 laps of track time...lol...

Default Drag brake adjustment!!!

Hi guys, is there anyway to adjust the Uforce75 to give it more drag brake? I am using the Uforce75 + pletty shadow combo. Currently i have all the DIL switches set to off. Anyone tried using the soft timing on the shadow? The schulze manual doesn't advise that though.

You can adjust the drag brake via U-soft program. I think factory setting is 10% and I found aroung the 20-25 % will give you the feel of a brushed motor but not that increasing the drag break will also mean heat and might thermal the control during a 5 min race.

Check the 3 motor wires from the esc to the motor and check that everything is in good connection. Only thing I can suggest after that is try another motor to isolate the problem. Is there any dents on the motor can?

Omg...i hope I don't have to buy another motor anytime soon to just to see if it's the motor....too expensive..

Well, I played around with all the wires, too everything apart - including the brushless motor...put everything back....

Now the stuttering is just the beginning of the throttle...very very very low speed - it stutters like crazy....but once it kick in it's smooth and goes through the entire power band. Weird...I don't understand. The first couple of runs I didn't have any stuttering....even at the lowest speed...

i have lehner and i tried changing timin. all i noticed is power band change i mean on very soft timing max power is on low rpm,
on soft it goes little higher, medium - even higher, high - highest power @ high rpm.

i usually drive on very soft, as i drive on relatively small tracks up to 25x13 meters.

Brushless motors will tend to do that on slow speeds during starting. You will find during racing is that you won't even notice it as you will always be atleast half throttle anyway.

yup.
same on my lehner, i can find that spot where motor coggs, but i never experience cogging when driving normaly even at low speed. it only appears when the car is still not moving but i push throttle just a few mm...
