Wicked Powered 50mm Screamer EDF
 
Here is my build thread on thew new Screamer 50mm EDF
I bought the airframe from: www.hobbyb.com
note: the airframe only kit has no control horns or control rods included so you will have to come up with your own.

Power system:
Wicked 6000 KV motor
Wemotec 50mm Microfan
Pentium 40 amp ESC

Lipo will be a 3S 1800.

Here are some photos.

1. No added wire length is needed on the motor/ESC
2. Fan area prep is typical for the wemotec as on the other 50mm models
3. I found the lower hatch was barely glued on so pulled it all off. Makes installation or servo wires and ESC much easier.
4. I did remove a little foam where the ESC is located to make it fit easier.

Here is the thrust tube template I made with centering ring. print out "full size" or "actual size", do not "fit to paper" or similar wording in your print manager.

I will post photo tomorrow of the thrust tube install.

interested in this build.
i have just taken delivery of my ARF screamer.
i will fly it on the stock setup for now however i may go the wemo / 6000kv setup down the track.
quick question will my 3s 1300mah 45c nanotech be up to the task with the wemo / 6000kv combo?

not if u want to use the power, imo. i tried that and it was very hard amp wise on that size battery. voltage sag will also be a issue.

chuck.

I thought about removing the forward duct but never did. Mine was glued fairly secure. It might be worth a little light glass cloth along the lip, I'll have to see how it holds up over time.

Well just spooled up my ARF screamer kit and the stock fan is really badly out of balance and rubbing on one side.
Never had an EDF unit so bad :-(
Lesson learned should have just purchased the airframe.

Instead of mucking around with it i have ordered a wemo / het 6000kv setup as i was ultimately going to upgrade anyway.

Will have to use throttle management with my 3s 1300 45c batteries

I never understood how the manufacturer can put in a fan that rubs on initial startup. :confused:. If you want to part with the motor, send me a PM with how much you might want for it.

I'm thinking of moving my Wemo/Wicked 6000 setup from my Skyangel F-16 into one of these so I can use a bigger battery. Any idea if the CG might work out OK with a 3S 2200 up front, like I have in my Skyangel T-45? Or if that would be nose-heavy, how hard would it be to move the fan back? Does the inside of the exhaust duct taper down more narrow as it goes aft (as it appears to do on the outside), or is it the same inside diameter all the way back?

I only use 3S1800s on the 6000 Wicked/Wemo setup as I basically fly full throttle the whole flight as I like the speed so I need the bigger lipo. If you flew around part throttle a 1300 may be OK but that is personal flying preference I guess. I just like fast :-)

I think I can get to balance OK with a 1800 mah, not sure on the 2200 but can tell you in a day or so. I need to get my fins painted then glued on so I can do a CG check but with no fins on I am close to the 45mm from the inlet lip (assuming that is the correct CG) so a 2200 may be possible.
