ESC set up and positioning

[Bunter]

Hi all

What settings should a begineer use with the MT stock ESC/motor combination please? I was going to go with;

standard discharge protection
auto timing
no brake
soft throttle
heli mode no governor

Does that sound right?

Also how are people mounting the ESC - I was going to place mine inside the frame but in the horizontal section rather than on the sloped section underneath the battery mount. But the frame cross members in that area don't have a good cross section to use servo tape with - or does it get to hot to use servo tape??

Thanks for any replies as ever

I've got mine located on that horizontal bar just below the battery. Used one tie-down and she is happy.

As for settings, I'm using the standard setup straight out the box.

The same here, but i add an external BEC and it helps a lot to keep temp of ESC down. Now it's a good ESC and it has a beautifull soft start.

What does the BEC do?

[EricW]

The BEC feeds the servos and gyro with 5 or 6 volts.
You can use the internal (build in) BEC of the stock ESC but it generates more heat in the ESC making the risk of overheating/burning it bigger.
The stock ESC gives 5V to the servos, with a BEC you can speed up the servos by using a 6V output.
If you plan to fly 4S lipo's instead of 3S you'll really need a seperate BEC next to the stock ESC.

I fly the stock ESC without any problems on 3S and without a seperate BEC btw.

Here is my ESC setup:
discharge protection disabled
standard timing
no brake
fast throttle
heli mode with governor
(90% flat curve in idle-up, I always fly in idle-up and use the throttlehold to start and stop.)

ERIC W could you explain that a bit,the use of throttle hold to start and stop?what is the advantage of this over using normal mode for take off/landing ?

[EricW]

I'll try :)

First of all, Ofcourse you can take off or spin-up in normal mode and switch to idle-up mode too, or simply stay in normal mode and fly.

Some advantages:
- I practise a lot in the Simulator (Phoenix) and always fly in idle-up mode, exactly the same as i do in real life.
- With this ESC and its very good soft start function, you can do it like i do it.
With other ESC's with a less smooth soft start function you risk striping your gears like this btw, so you have to spin up slowly in normal mode :)
- A fact: Flying in idle-up mode is more stable, direct and less wind sensitive.
- Take-off in normal mode and switch to idle-up in the air can be tough sometimes for a beginner, cause you have to use the switch in flight.
Now I master that just fine, but not when i just started...
- I'm not ready for 3D yet, but my heli and my flight mode always is.
- you learn to use the throttle hold more instinctively, good when you are about to crash ;)

Sometimes i take-off in normal, especially with my first lipo cause my Tx gives a warning when i turn it on in idle-up mode.
I always switch to idle-up mode ASAP, I don't like flying in normal mode where less pitch is less throttle.
headspeed drops to fast and not enough pop to react.
This can be set-up differently ofcourse, but i don't see the benefits of using it for anything else than spinning up the blades.

Eric how is the gov on the stock ESC? Hold well rpm or not?
thanks

[EricW]

The governor works fine on my stock ESC above a setting of 85% flat curve, picks up very fast and stays pretty constant overall.
I like it most (sport flying) at 90% flat curve.
Below 85% the ESC heats up enormously and the headspeed is not regular.
