It was time for a change of motor and I was keen to try the Muchmore Fleta ZX V2 after friends recommended it.

The Fleta ZXv2 13.5 is legal for the 2018 BRCA nationals. One requirement that all motors have to adhere to is a maximum fixed price point (£89.99). However the Fleta is one of several motors that can circumvent that price cap by adding tuning parts. So for this article I thought it would be interesting to not just look at the motor, but also the optional titanium rotor and aluminium screws to see what difference they make.


The Fleta Zx v2 comes packaged in the distinctive Muchmore packaging. The box calls out the following features:
  • Flow-Max2 aluminium cooling body
  • Strong Aluminium Mounting sensor
  • Fleta V2 stator
  • ZX balanced rotor
  • High RPM Super low friction bearing


Inside the box you will find the motor and a high quality flexible sensor wire. The sensor wire is nice and short so ideal for installing in most 1/10 onroad chassis.

The first thing you notice when you look at the motor is the new can design. The cut outs are there to provide much more efficient cooling. You can easily see the huge cuts at the front of the motor car and the sets of holes around the main stator. The quality of the machining is very good as you would expect with Muchmore with a nice silver bevel.

At the end of the motor you can see that it has markings for up to 50 degrees of timing on the can, although it can actually go a little higher than that. You can easily adjust the motor by loosening the three screws and rotating the plate.

With all of these cutouts, you not only gain cooling efficiency, but it also helps to reduce the weight quite dramatically. When placed on the scales you can see that the motor is only a whisker over 148g, a considerable saving of around10-20g than many of its competitors.

So we know that its light and it looks smart, but lets see how it revs. I connected the stock motor to my motor analyser and tuned it until I was close to hitting 6.Amps.  Why 6 amps? Well for blinky racing you want the motor to be running to its optimum rate to give you the best compromise between energy used and revs. Usually as you tune past 6 amps you will the motor will gain on a very small amount of extra KV but will use much more amps. (Note you always need to check your motor temps when tuning the end bell timing and / or gearing with a few controlled practice sessions to ensure that the motor is not going to overheat before you race it).

The result for the stock motor was a very impressive 4300KV, this is a huge amount of KV.

Driving the stock motor.

I was keen to see how the car felt with the Fleta ZX2. My local club track is small medium grip carpet. It was very obvious that the motor had a lot more revs available than my older motor.  The power delivery was really linear and smooth.  I never felt that I was utilising the maximum amount of revs so I moved down 3 teeth for the next run. This worked a treat and despite the lower FDR the car was noticeably faster than before as the motor was able to rev up much more easily. Overall I was really impressed with the speed and feel of this motor.  However I was not finished yet. As I has some option parts to fit


Disassembling the motor you are reminded about the quality of Muchmore products. All the of the parts are a good fit. Something that also impressed me is that the motor tabs are riveted onto the end can, nice and solid. The stator is tight in the can if you need to remove it. 


The titanium spec rotor should offer more revs and more torque than the stock version.

The titanium coloured rotor is actually a little shorter than the stock version. Although it comes with its own brass spacers to compensate for the different size. It weighs 4.8g less than the stock part.

For those that want to adjust the stator position, Muchmore do a spacer pack. I didn't need to use them as I was happy with the sensor readings (all exact at 47 degrees).

I assembled the motor and now was the moment of truth to see if the rotor was going to give me any more revs.

As you can see the rotor gave me an additional 532KV. Thats roughly 12.5 percent. This is coupled with a slightly higher gauss which should give you more torque out of the corner.
Before I gave the new rotor a test run, I just added the final touch. Muchmore also offer alloy screws as a replacement for the kit steel ones. Obviously I went for the Tamiya Blue ones.


They are 3.3g less than the kit steel screws

Screws are easy to fit, as you can just replace them one by one. So it takes only a few minutes.

Other than weight and bling the other advantage is that the screws are meant to give you slightly more revs as they cause less magnetic interference that the steel screws. As you can see there is a slight increase with these screws, but it is only very slight. I have been told that the screws gain more revs with the stock rotor as it does not have quite the same gauss (torque) so it is more noticeable, although I have not verified it myself).

The overall weight of the final motor with the alloy screws and the optional rotor is a very impressive 140.5g

At the track

I was keen to see if I would notice any tangible difference with the option parts. It was the same track so still very tight and small. However from the get go I could tell the car was even more ferocious from the corner. I also moved down a couple of teeth to a FDR similar to some of the guys who run boost and the car just came alive. Even though I could tell the car felt quicker out of the corner, it felt smoother. I wouldn't say that it felt quite as linear as with the stock rotor, there was a noticeable boost when the throttle was roughly half open. It was still smooth, and very drivable but it was a step change and motor would scream.

Overall


I am really happy with the Muchmore Fleta ZX v2 motor. It is punchy and lightweight and I have no issues with speed when racing with my friends.  I am still experimenting with the gearing options as the motor seems to have more revs in reserve. I have a couple of larger events coming up so I am looking forward to really stretching it's legs.
Obviously the cost of this motor with the option parts installed is quite a lot more than the standard price (An extra £50). So this does raise questions about it being a good thing for the class, I would not be surprised to see this backdoor on motor price be closed in the future. Although I must stress, that the motor in stock form was really fast, and it has a slightly more linear feel.  As thing stands I'm really enjoying running this motor, and look forward to seeing how it competes at over the season.
