e-Minicopter Joker > Help - What is your throttle curve for your Joker?

What throttle curve settings do you set for Normal, Idle 1, Idle 2?

I know everyone has a prefference and flying style but I just wanted to compare and get a good starting point.

It would be interesting to see the differences between 3D and non 3D settings.

My interest is to practice for "scale" flying but I would be interested to see any throttle curves.

Thank you!

No 'curve', and it depends.
If you don't use the V3, then you have to play with Normal mode a bit and put something like 25% at 1/4 stick and then up to your operating level for the rest of the points. Use the trim to start up. If you do use the V3, the 1/4 stick could be higher. In either case be careful about pulling the stick back below mid stick. Fly in 1 or 2.
Since you said you want to fly scale, you may want the V3 in & the 'N' pot set to give you whatever headspeed you want/need at 100% throttle. I doubt that would be 100% of 'N'.
Back to the throttle setting... start with 85% (N), 95% (1) & 100% (2). Idle 2 should always be 100% for arming the controller. Idle 1 & 2 are straight lined (same percentage across the stick range) only Normal mode should/could have a lower value in the first half of the stick.

Now, if you set the V3 'N' at 100% (or tick #10 of 11), now you have to find out what throttle % on the radio gives you the head speed you want. So, like I said at the start, it depends.

Thanks Dale.

Since you wouldn't sell me your Airwolf with the Joker, I had to go out and buy one

I'll need some time to digest your notes.

I just don't understand why we need governers when we can program a flat throttle curve in our transmitters, i.e., 90% across the board at idle up.

Then, simply have a linear pitch curve.

Thanks again for your advice.

Tony,
I run the V3 on both my Jokers. I think the big benefit is the soft start, along with some amount of onboard control in keeping to an rpm. Some folks use the V3 and others don't.
As far as the Airwolf, I still have to paint that thing! I'm just having too much fun with Joker #2 in P&B!

The reason we run governors is to keep the head speed constant.

Running a flat curve (i.e., 90%, 90%, 90%, etc.) only gives you 90% power with no load. Put pitch in the blades and load the motor and the current/voltage to the motor will not change and the result will be a decrease in head speed.

With a governor inline, it will sense the decrease in motor speed and increase the current/voltage to the motor (to its limits), to try to keep the motor at the proper RPM to keep the headspeed constant.

twguns,

Thanks, it makes sense now.

As another person recently explained to me....it's like a cruise control in our cars. When climbing up hill the cruise control system tries to maintain a constant speed (per the user's setting).

Therefore, here is my question:

If the governor is set at 1800 rpm, and my throttle curve is set at 5 linear points 0, 25, 50, 75, 100. The question is, with the stick at 25%, would the governor spool up the motor to 1800 rpm? And likewise, with the stick at 50%, would the governor spool the motor up to 1800 rpm as well?

In other words, the governor would not differentiate between 25% vs. 50% stick position?

Thanks.

Thanks everyone for your help.

Got my curves in normal and S1 tuned per my style. Governor is also set up.

S1 mode is set up similar to my Turbine Jetcat heli. It is very technical.....flat throttle curve Except, my pitch curve on the Joker is a V curve, while the turbine pitch curve is linear with less negative pitch.

Thanks again to all.

twguns,


this question was asked before and i haven't seen an answer.
What is the difference between the V3 at 11 tick and the throttle curve at 85% and the the V3 at 8 tick and 100% throttle ?
Which one would give the best maintained rpm.

I have just completed my Joker cx with 22t pinion and 24-4 motor.
running Tannic 11s2p packs.
rpm is 1760 on 6 tick and 85% throttle.
I was at 1850 rpm at 9tick. A little on the high side.


What a great heli !
smooth positive cyclic and collective.
Done all my mild 3d routine that i normally do with my R80.
