Airplanes that flitetest should build

50mm EDF and the option to run a pusher prop.
Ok, I have to warn you about 50mm's. I've tried and tried they just don't produce enough umph to push anything around decently. If you step up to 64mm 3s. We all have them in our bag. And look how fast my latest Mirage 2000 is going. I think I'm actually done messing with 50mm they just can't do it... just a suggestion for success...

So far it's worked great for multiple designs, do you have the fms 12 blade 4s version?

I'm waiting for 2 QX motor 50mm 12 blade 4s to come in the mail. I'm going to try them out. I was working with Powerfan 50mm 11 blade 4s and I just find them not that powerful and sluggish.
Maybe the QX will do the trick. I have 4 x 4s 1800 mah to out to good use...

Which 64mm and 70mm edf’s do you use? I’m thinking about getting some of the cheap 6 blade Amazon ones.

#Aliexpress C$ 14.42 | FMS 64mm 4S 3S 11 Blades EDF Unit With KV3150 KV3900 Brushless Motorfor RC Airplane Ducted Fan Plane

I'm using the 64mm 3900kv version because I have 10 x 3s 2200's to make use of...
I'm staying away from anything bigger as that would result in more battery purchases.
 
They basically take a drone motor and 3 blade prop and put them in a tube like an edf would be. It's efficient but stupid as well. In my opinion anyways.
The bdf is more efficient for its bigger propeller size, if you duckt an 13" propeller its going to be even more efficient fan. So you might as well put a pusher prop on your jet. Only the edf can provide the scale look and power for a jet

Anything to build up the EDF sector at this point would be cool. Personally, a mig 25/31 or a Convair Kingfish would be nice. They're both simple designs in terms of the square fuselage and simple enough wings, and both have massive engines, which on the RC would lead to keeping the inlets scale while preserving performance.

That Mig would be super simple to design. You know jets are actually simpler to make and design that prop airplane. You don't need help!! You just need a little self trust when scratch building. Just go at it and let's see what you can do...

Here, it's half built for you. Twin 50's... copy this approach. Toss a couple elevators in place, add a wood spar across both and center frame, fold a couple wings and your done...
Note: These are not the same plane. They are build examples...

Okay, so during the FT live build along today there was some talk about what FT should design and build next as a fast build or a master series. Well, I had a brilliant idea and decided to chime in with Amelia Earhart's Electra 10-E Special. Here is a write up. I do believe we should start building some special crafts here and try and tribute the special people and planes from our past.
So, here it is...
