Need motor suggestions Atlas 1/10

[Mike4xdriver]

Hey all, I'm upgrading my Atlas electronics. Been reading the motor info thread and its giving me a headache.
My build is for trail running and crawling my creek bed.
I'm getting a flysky FS-G11P system and want to upgrade the motor for better slow speed control. I'd like to stay under $100 if possible.
Suggestions?

The Hobbywing Fusion SE is available in 1200kv, or 1800kv. The 1800kv should be close to your current top speed. See video below for one in an Atlas. What's really nice about these two Fusion motors is they have the ESC and motor all in one. So you can ditch your stock ESC as well.

Atlas with above motor

Similar to above, but better specs. A few of the guys here have the Pro and they all seem to love it.

The Pro should be a huge improvement. Better top speed, and even better low speed control.

Comparison between SE and Pro

I second the Hobbywing Fusion SE, and if you prefer staying with a brushed system then I highly recommend you check out a Holmes hobbies motor which pair up great with the Hobbywing brushed ESCs available.

I run both systems in my crawlers.

@WickedFog beat me to it.

Is the fusion compatible with the flysky transmitter and how hard is it to add channels to the fusion reciever?

 

[TeknoJ]

It would be compatible with any receiver. The receiver is what has the channels, the esc portion of the fusion plugs into only one channel of your rx.

Tekno is right, but I can imagine being new, this is all a bit confusing.

Ok, your "radio" system consists of the transmitter (we say Tx for short) and the Receiver (Rx). The Tx tells the Rx what signals to send to the ESC, servos, lights, winches, etc. When the ESC gets the signal for forward, it sends that to the motor. The "radio" part of the RC will work with any ESC and motor.

The Fusion motors are basically just an ESC and motor built into one small package. So you would just remove your stock motor and ESC, and install the Fusion motor. Then connect that to your current Rx. After that, you will need to calibrate the ESC to your radio, which is a simple process, and will be explained in the Fusion manual, or we can help. There are also program cards you can connect to the Rx wire on your ESC to make the process easier.

...how hard is it to add channels to the fusion reciever?

The FS-G11P comes with an 11 channel Rx. You're going to have your steering servo plugged into channel 1, and your ESC plugged into channel 2. You will have 9 more channels to figure out what to do with if you want, or do nothing with them.

Some examples for the other channels...

• Lights
• Winch
• 4-wheel steering (2nd servo)
• Snow plow
• Gimbal for FPV cam (which can be two more servos)
• Dig unit
• Locking diffs
• Retractable wings, machine guns, etc

Basically, anything you can think of that you can control with an electrical signal or servo can be attached to and controlled by the Rx. As you will eventually see, there are some pretty crazy things folks have come up with to animate their RC's.

A big yes to the Fusion SE combo. I have them in all of my 1/10 crawlers.

Thanks for the input. I think I actually understand
Only other question I have is, is the way the motor mounts pretty standard or different brand to brand?

Pretty standardized, as long as you stay with the same diameter motors.

Depending on what kv motor you go with (more kv is faster) you might want to grab a pinion or two. Like if you go with the 1800kv SE motor, your current pinion might be ok. But I would grab one or two with one or two more teeth. I am guessing your current motor is around 2000kv. So you'll lose a little top end maybe? That's why I posted the first vid, for you to see the top speed and compare.

If you go with the 2300kv Pro motor, I would maybe grab a step down and a step up in tooth count in the pinion.

Make sure you check your motor's shaft size and the replacement motor so you know you have the right pinion(s). 540-560 motors come in 3mm, 1/8, 5mm shaft sizes. So you might want to check this before you start ordering parts. FMS does not supply any of this info.

Also, pinions come in various pitch's or mod's as it is called in metric. You need to know your pinion pitch/mod when selecting pinions. They do not seem to want to tell you this info either. So you will want a set of calipers to check the outside diameter of the pinion gear. The one in the exploded view below C1425. Measure across the points of the teeth, and with that and the tooth count we can determine the gear pitch.

Shaft measures 3.11 mm so I'm guessing I'll need a new pinion. Current pinion is 9.5mm 14 tooth.
I'm going to go with the 1800 se for my Atlas and probably get the pro to put in my K5.

Ok. So that is a 1/8" shaft and a .6 module pinion.

So stick with Robinson Racing pinions. Here are their .6 mod pinions

With the 1800kv motor, if that top speed in that video is ok, then whatever pinion he used is good. Your stock pinion will fit so try that and adjust. If you want a little more trail speed, go up a tooth. More low speed control, step down one or two.

Anything else I should add to my cart?

You have blue loctite? And it looks like you have bullet connectors going from your motor to your ESC, but on FMS's site it says the battery needs to have XT60 connectors, so I assume your battery has an XT60 already? If so, you should be good.

 

[Mike4xdriver]

Absolutely have blue loctite
I got a stick so it's easy to apply
My work pad holds it perfectly
