Found another nice Wattage EDF replacement

[KenP]

Just wanted to pass along what seems to be a very nice Wattage EDF replacement.

I got a Wattage Mig here on Ezone and of course broke the rotor when trying to setup the system with a brushless motor. So I did the reading here and was going to go with a 505 rotor but I can't find one. So I started to look for options and here is what I came up with.

Used the rotor from this HobbyCity EDF unit.

Had that EDF unit for another project so cut down the rotor and balanced it. Just used the stock Wattage shroud.

Then used this outrunner from HobbyCity

Spooling up the setup last night I stopped at around 70% throttle. 264 watts at 26 amps off a Rhino 1550 mAh battery.

So I figure getting 300 watts should be pretty easy.

The motor got a little warm but nothing exciting.

So just another possible option for those wanting to fly 64 mm fans that are based around the wattage setup.

Wattage/SF rotors and fans are available from several sources including this one:

Hi KenP, I'm using that motor in the HC 2.56in.(65mm) fan. I think it is a direct clone of the Wattage fan. Bphobbies still sells them and according to their specs they are 65mm 6-blade fans, same as the HC. With my Rhino 3s 2250 30C pack, that outrunner makes 500 watts on 46 amps. I don't think your battery is going to be enough for that setup.

I don't want to run the Wattage rotor, I keep reading threads on how that rotor just does not stand up to a whole lot of watts. That one of the best replacements was to put a Womotec 505 rotor in the Wattage shroud, but I can't find one of those to buy. That is why I went that route on the rotor.

You maybe right on the battery I do have a Rhino 2150 I can try it with, but until I have the fan mounted in a plane I am not going to come close to running it up full speed. My watts should be a bit lower given it is a 5 blade rotor instead of 6. I am not really sure of the pitch on these rotors either but the one from the HC 2.68 rotor does not seem to have the same pitch as the Wattage one.

If anything it is another option for a rotor. I will say though the rotor from the 2.68 fan is significantly more stout than the Wattage rotor.

Thanks for your Amp draw numbers though that gives me an idea of what size of ESC I need. I currently just have it connected to a 80amp that I am going to use in a different EDF.

I run them at 450-500 watts and haven't had a rotor come apart yet. I've found them to be very hearty. :confused:

I do find the stock aluminum adapter to be a bit soft.

I have read that in other threads as well but then there will be people that will post theirs came apart. But changing to a 505 or a cut down Kyosho people never had problems. I wanted to go the never have a problem route.

bhatch21 you were right about the battery not being enough. I ran the setup again with my 2150 and I got around 300 watts at about 60% throttle and the battery was only a 11.1 (started at 12) volts. So should be fun with this setup in my Wattage Mig.
