Freewing Avanti S 80mm 9 Blade EDF vs 80mm 12 Blade EDF


The new Freewing Red Avanti S comes with a 80mm 9-blade EDF with 3530-1900kV motor while the original Yellow Avanti S comes with a 80mm 12-blade EDF with a 3530-1850KV motor.

Any preference on either of these setups?

I might suggest getting the ARF plus and installing the 9 blade Jetfan 80 EDF with the HET 700-60-2085 (2085kv) with a Castle EDGE 100. Great sound, a bit faster than either stock set up, and a 4 1/2 min flight time with throttle management. (no hot batteries upon landing)
or..... With the 700-60 1738 motor on 8s, with the EDGE 100 for 130mph averaged upwind/downwind. on High timing: 10 degress)

I hope to get my new Freewing L-39 (ARF plus) rockin' and rollin' with a hotter 8s set up soon.

As a general rule, the more blades, the better it sounds.

In regards to efficiency, the lower the blade count, the more efficient it is.

As an example, a 2 blade propeller is far more efficient than any EDF.

Yes, that's what I've heard. MotionRC is indicating that most of the existing FreeWing 80-90mm EDF configured jets will eventually change over to a 9-blade setup and the some of newer 80-90mm EDF jets are already being configured with a 9-blade EDF.

Yes nine blade is more efficient than 12 blade.

It comes down to do you prefer the sound of a 12 blade fan or the longer flight times of a nine blade fan.

Personally I prefer longer flight times.

I would personally go with the 9 blade. As said above they are more efficient (only judging by what I've read, not from personal experience). I think the PNP is a pretty good deal and may jump on one soon. If you want a little more umph, you can go the ARF route and put what you want into it but that gets awfully expensive if you don't get the results you were after. Quite a few folks were putting pretty expensive setups in the FW F-4 not long after it was released just to find the stock setup is pretty decent for the price.

After watching vids of the 9 blade I think it sounds decent to be honest.

3d and EDF, some scale

having flown both versions, I like them but the 9 sounds more appealing to me personally. The 12 blade my friend has is the upgraded inrunner setup and his son is flying the 9 blade. I'll get him to link the video I took

I received one of the 9 blade 80mm units today and swapped out the 12 blade in my avanti. Performance gains are minimal and it sounds more like a vacuum cleaner. I will be putting the 12 blade unit back in.

That is good news.

Their New tiger Mirage 2000 with 9 blade 80mm performs much Better than the Old heavy 12 blade 80mm fan. Lighter and more agile, Better aerobatics.

The original Mirage setup is pretty tame compared to any of FW's newer 80mm setups. The metal shroud is also unnecessary extra weight since their fans now come so well dynamically balanced.
I would bet that the 12 blade 1850 is more powerful than the 9 blade 1900.

Anyone flown both these setups and have impressions?

We have both types flying at our club and both sound identical in the Avanti (really nice). Both seemed to perform equally well in the Avanti, but the Avanti really doesn’t need much power to fly well. I subbed a low power F14 setup into one and you would hardly notice it pulled more than 10% less power.
