Yes. I tried several throttle curves and all had the same result. Using the stock brushed motor, it feels like the motor runs very fast in normal mode and just doesn’t have the crisp response like in other modes. Again, it’s probably because the programming of the board is trying to make adjustments to stop you from climbing or falling too quickly.

I suspect that those that would install the brushless motor are only interested in flight mode 3 anyways

Here is what the finished install looked like:

Iíve never installed one of these before. Is it the same method as CP S? Can I look at instructions from those threads to do this?

That's a good looking installation!!! Only thing I would point out is to be sure those stiff motor wires are not tilting the board. That could cause weirdness.

Should be the same instructions. I wrote about my first brushless upgrade here.

All of the wires are soft and pliable. Itís just held to the main board with a little double sided tape like the stock CPX setup.

Chris1683,
Could you please post a picture of the ESC plug that goes to the motor socket on the board, so everybody can clearly see how it should be done properly?

Here you go. Fairly simple. The only thing that needs to be changed is the motor connector. I opted to change the ESC power wires to eliminate the extra harness but it’s not necessary. Just cut the old connector off of the end of the orange wire and solder on a micro JST.

I love the dedicated motor wire--it looks like you soldered on a whole new wire and then crimped on a new JST connector. Yes?

That is correct. I actually have a few spare sets of brushless upgrade kits for the CPX. If someone is looking for a pre-wired brushless upgrade for their S2 they can PM me. I can add the custom wire with the S2 plug ready to go.

Thanks! Maybe once I'm ready to dig in to my brushless upgrade.

Any idea about how much weight the upgraded added to your S2? I managed to upgrade a CPS with only a 2g increase. I thought that was pretty good at the time.

Yesterday, I installed the HH brushless upgrade into my S2. I decided to, basically, copy the install that Chris1683 posted above because, well, it's the best way.

It is hard for me to see such small solder points, but I tried my best and the heli seems to work pretty well.



Definitely not the prettiest of solder jobs, but I really wanted to keep the wires as short as possible. Of course this made soldering even more difficult.



Copying Christ1683, I soldered on a longer signal wire and routed the wire behind the board and up to motor socket. The signal wire routes neatly beneath the tail motor wire, which will be a big help later on, I'm sure.



Using a piece of double-sided padded tape from my Trex 150X kit allowed me to mount the ESC without obstructing the rubber post that supports the board or the blue/red LED on the board.

Before the installation, I weighed the S2 without a battery. The scale waffled between 26g and 27g.



After all is said and done, it looks like the brushless upgrade added about 2g to my S2. That should be fine, though.



Gave this brushless S2 a quick test flight even though it was raining, .

As reported by others, only Idle2 works fabulously! The board puts the head speed at 100% no matter what the Tx says. I noticed the tail does struggle a bit more to keep up with the brushless motor when I punch it. Should be tolerable, though.

One point of frustration. While I was routing the wires, the lower port canopy post just fell loose! I have no idea how that happened, but the canopy and the rubber post seem to be holding in place once all is installed into place. I didn't notice any bearing on flight, so maybe this was unnoticed previous crash damage.

Nice write up and looks great! The tail motor should be able to keep up. If the tail is struggling it’s either a tail motor wearing out or a small bend in the feathering spindle. Those spindles always cause havoc if there is even a slight bend.

Thanks!

Lol, I may have both a worne tail motor and a slightly bent feathering shaft. This S2 has had a lot of fun!

I'll just wait for these issues to become bigger before I do any more work.

Hey, guys, I decided to do a write-up about installing the brushless motor into the S2:

Upgrading a Nano S2 to brushless

Hope you like it!
