Throttle Curve Blues
I cannot for the life of me find the sweet spot for my throttle curve. I was using 0,60,80,90,100 gives me good head speed and I'm at 68% gyro locked in (I like this), but throttle surges between 0 to 60 (you guys know what I mean)..to big of a gap between 0 and 60. I tried 0,40,60,80,100...too low head speed but smooth throttle with no kick...but lower gyro setting. I tried 0,57,80,90,100...tail gives a slight kick from 57 to 80..I don't like this. The motor is a Suppo 1000kv (Altitude Hobbies) rated @ max 70 amp ESC. I'm using an Align 70 amp with the BEC set to 5.5v, the ESC is programmed to 1,2,2,2,3. My pin gear is 16T and stock main gear of 170T. I'm running 6s 5000mah 40c Turnigy. Any suggestions on a smooth throttle curve with no tail kick....??? Please

Do you feel strongly about running a curve? Governor mode is really sweet. The only time I run an electric on a curve is if I'm running on the bench for some reason.

The ESC doesn't have a governor mode. Are you suggesting a flat curve...?

What are the programming parameters you quoted above? Isn't the fourth parameter aircraft mode? Helicopter 2, should be governor mode or I'm thinking of wrong esc.

Ya wrong ESC. It’s the ESC I took out of my Trex 500 I sold. I still have the 75G ESC and separate BEC the Heli came with. The reason I wasn’t using it was I didn’t want to have a separate battery for the Rx and electronics I just wanted to run everything off the main battery.

Either a new Tx with a 7 point throttle curve instead of a 5 point.
If the ESC has a soft start feature. Then your first point could be 40 and let the heli spoolup when flipping out of Throttle Hold.
Last option would be a GOV.

Well I'm using the DX6i Tx. The ESC does have a soft start feature of which I'm using. Ya the closest I'm going to get to a GOV is using a flat curve. I've had many a Heli but never had an issue with PC or TC curves. Its a Trex 600, but then again maybe its just me. I'm having a brain fart or something. I dunno. What about 0,50,60,80,100 or 0,50,80,80,80...? If worse comes to worse I'll just go back to what I had 0,60,80,90,100 and live with it. I don't want to have to get another ESC either. I'm gonna experiment from this point on and see what I can figure is the best curve with the least amount of adverse affects. Thank You sir for your helpful advise. Much appreciated. Happy flying.

Try this. At full low stick 0. Then at 1/4 stick go up to 80. Half stick go to 80. Full stick go to 80. Start the heli by using the throttle trim. Go one click at a time until it starts to turn over and see where that is. Keep clicking up to Go to full trim. Then go fly and tach it in a hover and see if you have the head speed you want. If low, bump up the number. If too high, lower the number, but keep the same number from 1/4 stick to full.
If you adjust your low point at 0 so that at full throttle trim you are just below hover rpm, it should fly fine.

Then you can use NORM mode for take off and landing, then use maybe IU1 something like 90-80-70-80-90 and IU2 100-90-80-90-100
Adjust numbers accordingly but don't fly in normal mode,
Just use it to spool up.

I always fly in normal mode. 4 years and counting. Never had an issue. I don't fly 3D. Old man sport flying (circuits, figure 8's, big air, FFF, just putzing around the field.

Little confused by this....?

On a new electric, I always start with:
Normal: 0-60-60-60-60
Idleup1: 80-80-80-80-80
Idleup2: 100-100-100-100-100

Then, I adjust the numbers for the desired head speed in each flight mode.

GOV mode set, forget, even if it means buying an ESC, so much easier and more efficient, just my 2 cents

Well can't argue with that. I didn't want to but its sounding better all the time. I get tired of it sometimes trying to get the right PC and TC curves. I have to stop being stubborn and just do it. So a new ESC is in order then. But to get the right one that is easy to program and "simple". I like simple.

I only fly in one mode only "normal".

Excellent, me personally consider the pitch curve to be part of the mechanical setup, once set never touch it, with the rpm that’s the variable but set the rpm and if you got a CC esc it will tell you the “curve” to put in radio. Keep us posted

If you still have the original 75 amp esc you could just add something like a Castle pro Bec. Much cheaper than buying a new esc. It will handle the input voltage from your 6 cell pack so no additional receiver battery needed.

Well, then you can setup IU1 with a 0-60-60-60-60 curve then spoolup with IU1. Once up to speed, switch to normal mode and fly.

Or do the GOV like you said.

I have the Align 75G ESC with separate BEC that came with it but opted to use the Align 70amp ESC out of my Trex 500 I sold so I didn't have to use a separate Rx battery to power the electronics. I could throw it back in and go from there. I didn't even try it when I got it. I took it out right away and dropped the motor to a 1000kv motor. I'm running a head speed of about 1880 to 1900 max. I'll get it right eventually.
