What's the green stuff that you used to balance the fan?

All Wemo rotors come balanced from the factory. (that's the green stuff) . I use polymer clay, locked to the housing with tinned epoxy, if needed. (as with Change sun, E-flite. Haoye, ETC>)

Clocking the spinner while running an assembled fan/motor, on the bench (at lows speed) is all that's usually required to achieve the smoothest operation.

The first thing to do when assembling Wemos, (before installing the motor into the housing) is to heat the shaft adaptor. (the bore is slightly undersized). so it will slip on the motor shaft easily. Apply loctite to the set screws and install into the adapter. (mark one of the screw location with a sharpy so you distinguish one from the other). The run the motor with shaft adaptor installed in a vise. If necessary. adjust/ alternate the first screw to be tightened. This will allow you to get the shaft adaptor running silky smooth. If you don't have a dial indicator. test this while adjusting after adjusting the screws, by placing your finger in the adaptor where the rotor will sit. and feeling for the smoothest operation.

Wrap the front of the motor with tape, to well center it in the housing.

Be sure to install the rear "centering ring" that comes with the fan. You may need to open the I.D. a bit to slide it over the installed motor. and into the rear of the housing.

Here's the Evo chart.

Sounds great and feels equal to or a little faster than the 5 blade fan. It's not as "wooshy" as a CS 12, but more quiet. Here's a video.

Mine is the 3600kv motor. I think it will be too much for 5 cell operation with the Evo rotor.

Yes it will fit, buuuuut..... The E-flite housing is 1.5mm larger in dia than the Wemo (just measured it for you).

This means there is 0.75mm more tip clearance (per side) than in the Wemo Minfan Pro housing (it's actually a "69mm EDF").
Your going to see tip losses. and my suggestion is not to use it.

+1 to everything Gary said. I use modified 12v HP server PSU to run my fans on my test stand. You definitely want to clock it to get I running as smooth as you can.

As for the 3600kv motor, not really sure if it will take it. You can try it using a temp gun and measuring amp draw. Start slow and limit WOT on a stand, taking readings at intervals. My guess is it's going to be a "hot" set up. The eflite motors are good, but you never know.

Stock set up with retracts and flaps on a four cell 3650 45c 65 burst. She flew well not blistering fast but okay. So now I want fast so I have a 80 amp and a 12 blade 70mm changing sun on a five cell. Has anybody ran that set up yet?

That's cool. Where did you get the tv nozzle for the habu? I hope you do a video and post it on the thread. I would like to see how well it does.

I don't know that it is a four to six cell set up so what ever comes with that. Do any of you guys know where to get a good priced 12 blade with a motor 70mm? Please let me know. A buddy of mine has the stinger 90 on six cell with the free wing set up and this thing flies like a thing of beauty. Rips along very good and sounds great. That air frame just flies good any way but when you put that set up in it wow!! But I don't have $399 bucks that shipped and no tax or shipping beautiful jet.
