CFK 19.8 x 20.5 MADCAD Advance
CFK 21 x 19.6 MAGCAD Advance

Very high pitch! Has this motor such a low Kv?
This seems to be a different developmentpath in relation to the new high revving Q80:

New motor + YGE90 controller. With the motor came the MADCAD propellor.

Weight is comparable to EVO 30-10 (587 grams!)

EDIT: Cannot upload pictures, will try later

Hans Meij

Will show mine then. For size comparison a EVO 30-10 and a C50

Hi Glen,

The first motors are being shipped all over. I received mine yesterday, and I know Chris is getting some at F3A Unlimited. I am sure Icare is also getting some. I am sure the demand will be high, so availability will probably be scarce for a period of time.

As soon as I am able to revise my existing mounts on one of my planes I will get some preliminary numbers. There is a potential for some flight testing depending on what our weather does.

As always I will post whatever data I can collect here and on my blog!

Hans Meij

It is just as Chad said, I just received it. Placed my order at Plettenberg a long time ago.
What I only can say about it now is that its a jewel. It has a marvellous built quality.

Is this new motor set up for nose ring mount, firewall mount, or both?

thanks

Front mount only.

I intend to front mount with a ring support on the rear like the C50 or the Neu. Since it is not an outrunner the outer can is stationary so this should work the best.

Thanks Mr. Unlimited =D

These props have a very special form so I don't think you can really compare them to other props. We just have to see how it works out.

Here the missing picture of the YGE90 controller with actual weight.

Hans Meij

Volkert, do you have a pic. of this prop?

wagen017

Here you go. For comparison I added the RASA5 on my Twister as well. The black spinner has the MADCAD, the silver spinner is RASA5.

Hans Meij

Volkert, thanks. I see they went even further in reducing surface area at the center.

The Advance ended up looking a lot like the Neu ORK models I pointed out last year. Wonder if the Neu models have anywhere near the performance?

Anthony,

From the looks of things the 30-09 seems overpowered for an 11lb/5kg plane: a) do you feel the same after using it? b) what percentage of the throttle do you find you are using? c) have you considered propping down to a 20 x 13 to see what that feels like? Given that this motor weighs 565g (20g lighter than the 30-10) I would think this would totally replace the 30-10 if a more efficient prop could be found to bring the power usage down. Anyways, just wondering aloud. Can't wait to get one of my own

Joe

P.S. Missed you on Saturday. I was there in the AM and hope to catch up with you soon!

Hi Joe,

Good to see you active again. Was starting to worry you had fallen out of the game. I was at the NEVRC contest Saturday putting in a few lousy F3A flights.

The 30-09 makes good power but at very high amp draws. Luckily, my packs are holding up but I don't know for how long. The more I practice the more power I find I am using to keep the plane happy. Part of this is the fact that I am flying my old Brio converted to E-power and part is the demands of the F3A/Masters schedule. This plane is all of 5kg w/ very light packs and has been described as a flying watermelon so it really wants all of the power you can put in it. In some wind last week at Jackson I did come close to full throttle several times in the sequence. Even in the much more favorable conditions yesterday the plane took a lot of throttle to get through the figure 9 at the end of P11. Flying around 160m and medium to large maneuvers I was using around 4000mah @ Jackson and 3500-3700mah in calmer conditions yesterday and most likely flying too slowly.
I flew a 20x13 on this plane and was surprised at the performance but the amp draw wasn't much lower. After I tried the 14 pitch props my 20x13 hasn't seen the light of day.
If I were to reconfigure I would definately look at the Advance 30-10 or a Neu F3A. Both offer power and better effeciency.

HI Chris.
look at the dimension of the drawing.I found one wrong dimension, The nose blots wasn't 3MM.check it out I bought one from you in Muncie.So i check the nose bolts size are 4MM.

I hope this isn't too old to dredge up, but I got this motor for the Spark and am very impressed by the first day of flying yesterday despite the crappy conditions.

First off, like a total moron I downloaded the data log from the CC HV80 Ice2 and promptly deleted it from both model and computer, so I don't have any data and will have to wait until next time I fly for some more.

However, I was flying it with a PT 20x13 and as you have all noted this thing pulls like a freakin' monster. Because of the above stupidity I don't know how many amps it was pulling. However, I could not resist flying the Advanced sequence followed by some full-throttle rocket ship verticals just to see what it would do, and then I landed promptly to check the motor temperature as well as ESC and batteries. Granted, it was pretty cool outside with ambient temperature of 45degF, however the back of the motor case was only very warm and could be touched easily so I estimated the temperature at about 120degF, the ESC barely warm at perhaps 80degF (so low it was not even worth guessing, really), and the battery temperature perhaps 110degF at most, with all the batteries I flew, which were Zippy 20C, Rhino 20C, Sky 4400 40C, PU 25C (which was a bit warmer, but still nowhere near excessively so) and Turnigy Nano 25C. The Sky 4400 40C's are VERY impressive.

The only other bit of data I have is that I recharged the Sky 4400 to get some idea of mAh consumption, and it took 3400mAh, this after flying the Advanced sequence in fairly windy conditions and then some of the aforementioned cavorting and rocketing around the sky. So that is a pretty good result as well.

I have really good airflow over the motor, with a balsa sheet air scoop directing air up to the motor space from the main front vent and also a spinner with a large hole in the front to let air in.

Although I had visions of trying different props and working with the throttle curve, the weather was so nasty - cold with a 15-20 mph 90deg cross wind - I just bagged it an went home.

Well, it is very early in the pre-season, after all!![]

cmoulder

Finally got some halfway decent weather. Cold - as in 26degF upon arriving at the field - and rising to 44degF later, and also a bit windy at first but calming down nicely to about 5-10mph as the day progressed.

I got in a lot of flights, mainly because I was tweaking the Gator wing adjusters I installed in the Spark to cure the aileron trim issue that was caused by the holes for the wing fixing bolts allowing a bit of slop and therefore inconsistent positioning when installing the wings. Got all the trim out and flying better than ever.

This time I made sure not to erase my CC data logs and was at last able to see what sort of power demands are being made by the motor and prop, which is a PT 20x13.

A good generalization from looking at the graphs is that maximum amps is in the 95-100 range, ESC temp is 109degF max (but it WAS cold out!), watts around 3500 and rpm around 6700. The motor was only warm and the batteries just warm around 100degF according to the little IR thermometer. This pretty good, and I'm going to try a 20x12 to see how much the amperage drops. Clearly, a 21x14 or a 20.5x14.5 is too much prop for this motor - no wonder they were getting the motor hot and pulling large amps!!

Typical graph below with some data fields left out to declutter.

Interesting. Just wonder if the high amp draw can be fixed by lowering the max throw of the throttle.

I also played pt 21x13 prop with Neu motor and felt the pull is more constant than apc 20.5x13. More is expected of the maximal pull at top of an upper line.

cmoulder

Certainly the amp draw will be reduced with the 20x12. However, it is my recollection (perhaps ffrom a discussion with Dave Lockhart) that there is plenty of capacity in the Ice 80 to handle peaks of 100 amps with ease.

So, as it is, it is probably a durable and reliable combination. Although the results might be different when the hot days of summer arrive, it is reassuring that none of the components got the least bit hot, which is a good indicator that electric components are not being pushed too hard. This was especially true of the batteries; even though it was pretty cold out, I expected them to be a lot warmer considering all the aggressive throttle work.

Another factor to consider is that I was intentionally pegging the throttle with different batteries to see what the max amps would be. Next time I fly I will make it a point to fly a contest sequence with proper throttle management and then land promptly. CC data logs for mAh usage and data from the CellproXP chargers will be compared. No doubt it will be a lot less than what I experienced today. I also found out I can fly the Advanced sequence big and fast in the wind with 4400mAh 40Cs, no problem.

In normal contest flying full throttle will not be needed, even when it's windy. I suppose I could use a switch for separate throttle curves, but thus far I have one throttle curve (which I'm still working on) and full power available on the stick, even if it is not often needed.
