Yippee!
GWS EDF55 will be 9% more thrust than Varsa55 at 130W!

GWS EDF55 will be 9% more thrust than Varsa55 at 130W!

I am very proude to inform you that GWS EDF55 will be 9% more thrust than Varsa55 at 130W! Varsa55 will get 280g but GWS EDF55 was measured with 305g under the same condition!

The France editor wrote this test report of EDF50, EDF55 and EDF64 in 5 pagesn with many datas on the France RC models' magazine.

The top end of GWS EDF55 can be up to 450g; GWS EDF64 can be up to 570g if you put a strong BL motor insteaed of original EM300H motor.

Did you ever tested GWS EDF units with BL motors and have test datas to be posted here?

can you tell us what motor/pack setups have been used to achieve the 450gm? I currently run a 280watt input on a hacker B2012L 3s lipo for about 522 grms (that is in a fully ducted setup)

here is an early thrust test, used a 3s2p 2100 TP pack. Now it uses a 3s2p 1570 apogee about 3.5 oz lighter and runs stronger or a 3s 2600 polyquest pack (about the same as the old TP 3s2p power wise) but about 4.5 oz lighter

Your 522g measured on which EDF?

That's an article on a France magazine of 5 pages report about GWS EDF50, EDF55, and EDF64.

Need to find more detail in the contain, but I am in USA now. GWS staffs will bring back this magazine back to Taiwan on 18th. I will ask them to fax to GWS USA.

Your 522g measured on which EDF?

oh sorry about that, it was with the vasa 55. I have thought about trying the GWS 55 as a lower cost alternative, but was unsure about how much power it could safely absorb.

I am a big fan of the EDF40, when powered with one of the new BL 12mm motors it is very impressive.

I also like the heat sinks for the 280 and 300 motors. It would be nice to have an extrusion based heat sink that would fit a 20mm motor, just what is needed when exceeding 200 watts with the current 20mm BL motors

Hello Mr. Lin

My own tests show that the fans are very similar in performance, with the Vasa55 having a 2-3% advantage over the EDF55 with the same motor.

Like Dave said, the EDF40 is a lot of fun with the Feigao brushless 12mm motor. Plenty of thrust and speed in a ducted install.

I have both the 5300 and the 5800kv motors, both work well on 3s, the 5800 will produce more thrust if the battery can hold its voltage. The 5300 is not as hard on the battery. For EDF and these small motors I only use 3s, the 5800 will need a heatsink though and the GWS 12mm heatsink will work until something more appropriate comes along.

I tried inlet vanes on the stock GWS 55 with the 150 motor on 9,6 volt
in the model i do have 200 gr. of thrust. with the vanes.. and that is 50 gr more than before.
Next logic step to me will be this tranformation to fan and motor integrated somthing like this

Mr Lin;

Could you please stop joking around
But I have to consider that 130 watts is the sweet spot
for EDF 55, not at the higher wattage, 130+ watts, where the
other fans like vasa, Wemotec, kyosho really shine

take it eazy...
Looking at the wemotec fan and looking at the gws fan... they are different yes... but so are the price..but if you look at the skills put into the fan production ... gws is the winner. It is not constructed for 1 KW. but a deasent produc for the money, and sure the way into fans.... for a lot of people.
