Welcome to exactly where we were around this time last year...

Value for money/Performance/Overall 'fit' to an M03? Hobbywing ezrun wins hands down. The perfect amount of performance, and unbeatable value for your cash.
To run a 17.5, the ESC alone is usually twice the price of the entire H/Wing COMPLETE system!

Ummm...who runs droop? We don't.... In 99% of situations an M03 works far better with no droop at all.

Toon,

The 17.5 will always be slower than the Hobbywing system as you can not change the gearing on the mini.

I have tried this before and was being beaten by sport tuned motors. The car does not have the torque or punch. I even set the timing to max and the punch to full. At the time I was using a SP 17.5 and also tried a Novak 17.5 with a speed passion ver 1 speed controller.

I agree with TG that the Hobbywing is the better system.

Regards,

Calvin.

I'm thinking about getting an ezrun system to try and get a bit more performance from the car, but is it worth considering a 17.5 brushless system instead? The 17.5 would be sensored compared to the ezrun sensorless system, so may provide smoother control, but the 17.5 motors I'v looked at (Novak, Tekin, Nosram) seem to have a lower Kv rating, around 2200-2300 at most. But then again, the 17.5 is a 540 size motor, so may have more torque than the 380 (internal) size ezrun motor.

Of course, I could just get an ESC that can run all types of motor (brushed/sensorless brushless/sensored brushless) and try both a 17.5 sensored and a 3000kv sensorless motor, but that's not gonna be cheap...
With the restricted gearing of the Tamiya Mini, the Ezrun 3000kV system will easily beat the 17.5 motor. WE have been down this track here in Australia with a huge amount of testing. The Ezrun is by far the best system for the MIni. Add the fact that the Ezrun is cheap and you have the perfect solution

It looks like a no-brainer for the best brushless system for my mini then. One Ezrun 35A/13T combo has been duly ordered on the 'Bay. Thanks for the advice guys.

edwintklee,

It is a 540 size motor.

The Hobbywing BL system approved for use in Mini within Australia is the 380 size motor with 13T etched into the rear portion of the motor can. I can not tell you how it would go,however if it is anything like the Exige system motor then it will be quicker than the 380 size motor.

Regards,

Calvin.

I'm hoping it will be more lipo friendly for guys who want to run bigger capacity packs. (4000mah+)

It looks similar to the ones on the F103. Perhaps more secure against a t-bone, and also to protect the electronics at the side?

from the pics it sure looks like the same old lipo "un-friendly" stick pack shape...also they moved the servo to lower cg but they replaced it with a full bell crank system which some will switch with alloy and bearings which will weight as much as the servo that moved...

The whole thing smacks of a quick attempt to move the servo, not for C of G reasons, but purely to get it off the top of the chassis and so you can fit a wider range of bodyshells - it's as simple as that really.

I don't think racing considerations had anything at all to do with it.

Good point...seems to be the trend nowadays starting with IFS & now the HPI Cup racer & M0-5 here.

Just think of all the new bling bits, you will need to buy to be fast.

I am interested in how the steering setup will work if you want to run the different chassis length's. Or will be stuck with one chassis design/length with the MO5 Pro.

I think for now I will stick to what I have, however I better put a pre-order in so I don't miss the initial run.

Later

Calvin.
