Default ESC setting issues

Hi Guys,
After setting up the esc I notice that motor only starts turning when throttle stick position is at 40%. Already confirm that my throttle is 0-100%. before setting up esc. Is this normal ???

Thanks

I thought the fireball esc's were already setup. How did you set it up? You should have a flat curve for flying, example 70%-70%-70%-70%. I believe the esc's are a decased hobbywing and if setting up gov store than you need to have 50% throttle curve and run for 15 -20 seconds or so, blades on and 0% pitch. Check the hobbywing thread for exact gov store procedure, sticky at top of threads and videos on how to, pretty simple procedure.

you need to set the throttle end points first, then set up the gov store.

For either ESC governor mode it’s normal to come on at 40%

If you fly with a linear throttle curve, you will notice that 40%. But you shouldnít be flying with that type of curve. Use the gov and just flick out of hold when your ready to take off.. at half stick. It will spool up nice.

Thanks Guys,
Yes I only use this to set up the initial part for the esc to recognise the end points of the TX. I'm leaving the rest of the setting in default.
For idle 2 & 3 off course I use flat throttle curve but on all my helis I always use progressive throttle for idle 1, so I was kind of surprise that I got no responds from the motor till throttle was 40%.

That curve for 1 or normal isnít needed.. you canít go inverted, and is useless and nothing but problems. So why even have it.?

agreed, I don't like even having a 0% to 100%. If you forget your in that mode and go inverted, well the rest is history.

I also have gotten that comment. I also use Normal Mode with a linear throttle curve although yes in theory I only need to use it once during setup. IU1 and IU2 are my normal flight modes but since I use a timer I always just use IU2 to keep a consistent time with my crappy flight style. Only on the 420 where after crashing the 380 I started using lower mAh packs I had to tweak my timer but I ended up lowering my headspeed to have the same timer.

flip it in normal, you'll get rid of it real fast.
again, serves no purpose, except for setup and uses an extra flight mode.
vcontrol doesn't even have a normal. just 3 banks. and no 0-100
this subject has been beaten to death.. use what you want really, but normal 0-100 throttle curve for flying is an accident waiting to happen.
really, I don't want to see anybodys heli crash cause of a normal 0-100 curve.

So how does Vcontrol work? You don't set a throttle curve? You just tell it what is your flat curve throttle percentage? And, how do you setup throttle endpoints?


EDIT: I kind of use it that way as I got used to it like that from the sim. I get off Throttle Hold on IU2 so use the FBL or ESC soft spool up. Then baby auto so from beginning to end I am always on IU2. So if my radio doesn't say "Flight Mode 2" when I release TH something is wrong

theres a procedure for setting up the endpoints for vcontrol, but I don't want to derail the op's thread more than I have.. so sorry for that..

Absolutely agree. Not needed with electrics. FBL soft start or linear start is sufficient. Some people will do everything they can to protect what they have like getting FBLs with rescue features, go overboard with new parts after a crash, etc, but will not get rid of the one thing that could easily cause a re-kit type of crash. It only takes once to not catch that you had in the opposite switch position you expected and the, "I always do this..." excuse for leaving it programmed in becomes pointless and if it happens, you pretty much deserve it.


Blame it on Blade...every program manual they have has this for most all of their birds and many of us start there. I don't hang on to any of that beginner stuff. Even if a .01% risk as some might think, 100% stupidity if it only takes 10 seconds to program out and remove ANY chance.
tonys-heli and Thickfog like this.

when someone is first starting out having a "normal" curve helps ....and is usually a very good thing...
