I received a Himax 6330/F3A outer runner today. The dimension is exactly the same as the Himax 6332-230 and the AXI 5330/F3A. But the performance is outstanding.

Weight of my AXI 5330/F3A is 660g
APC 20.5x14E, TP 5300 10S LiPo, 5700 rpm at 72.2A (this is my normal flight setting)

Himax 6330/F3A
Weight: 602g (compare to 685g of Himax 6332-230)
Kv: 200
APC 20.5x14E, TP 5300 10S LiPo
A side-by-side comparison, 5700 rpm at 61.9A (not push to full throttle yet)

To resolve the loose magnet problem, they put an aluminum retainer behind the magnets (ha ha! That's my suggestion!)

Although it is still at heavy side, it is ~2 Oz lighter than the Himax 6332-230 and AXI 5330/F3A. The performance is pretty close to the Plettenberg.

As I was told, this motor is a prototype. I'm not sure when will it available and what's the street price. I replaced my AXI by this one already. I will use it in this weekend's pattern contest at Sacramento.

They finally heard our feedback!

Here are some pix. Prop hub and back plate together is 47g. So the motor weights are:
Himax 6330/F3A: 649-47= 602g
AXI 5330/F3A: 707-47= 660g

Luke, thanks for the update and pictures. We will see how it performs at Sacramento.

More bench test data today:

Hmax 6320/F3A
TP 5300 10S LiPo

APC 20.5x14E, 6100 rpm at 67.3A
APC 20x13E, 6150 rpm at 61.05A
APC 19x12WE, 6240 rpm at 60.95A

I will have EagleTree flight data by Friday.

Hi Luke,

Are these full throttle readings? The rpm and amp draw are significantly lower comparing to the Axi 5325 turning the same propeller. Assuming the voltage was the same, the result is lower power for the Himax.
You also mentioned in the first post that the 5700 rpm at 61.9 A reading was not taken at full throttle.
Looking forward for more info.

Flight data today. Energy usage is significantly lower.
All data were from my e-Focus II, weight 11 lb. 4 Oz.
CC Phoenix 85HV
One complete AMA Master sequence
Two old data from Himax 6332/230 and AXI 5330/F3A are for comparison.

For electric, the voltage and current give you "Input Power". It is NOT 100% converted to output power. In general, power loss is heat.
When motors swing the same prop in the same rpm, their "output power" are the same (or very simliar).
In this case, the lower the current, the lower "Input power" is needed. In other word, more efficient. So, yes, Himax 6330/F3A needs lower input power. Since it is more efficient, the output power is the same as Himax 6332/230 (or Axi 5330/F3A). Consequently, I don't need TP5300, the lighter TP4200 or even TP4000 will be more than enough to finish one AMA Master sequence. That will save me 200-300 grams.

My Feedback: (11)

I saw this at the Sacramento contest. Looked at his current usage after charging 3200-3300 mahsfor masters. I used 4000-4100 with my Hacker C50 14xl constantly all weekend. I Looked at his power. I am impressed.

Luke, a suggestion for the manufacturer. The aluminumprop shaft looks to be the larger size of 12mm like the Axi. Have them shrink it down to 8mm like the aftermarket one that is available for the Axi. It saves more weight and it is much easier to ream out props. The 12mm isn't necessary. I ran the 8mm when I ran the Axi with no problems.

Looked good. I am impressed!!

Thanks for passing on this info!

Chris:

About the 12mm prop shaft; Himax is going to standardize to 8mm shaft in production model.
I was told, the new motor will be available in 2-3 months.

Any thoughts as to how this compares to the Dualsky new 6360 12t weight etc

woodie

Based on what I weighed the new DS 6360-12T at with prop adapter, etc, the Himax is quite a bit lighter. Probably 2+ oz lighter

Got words from Himax. Based on our feedback, the production model have some changes over the prototype. See CAD drawings below.
1. 8mm prop shaft
2. Two sets of mounting holes at base
a. Three M4 holes at 40mm diameter circle to fit Plenty foortprint
b. Four M4 holes at 44mm diameter circle to fit AXI and Himax footprint

The pre-poduction test models will be available soon, I will update the test data.
Production model should be available in US by early 2010. No confirmation about the street price, but my understanding is around $250.
