Hiya guys. I recently got a 3d printer (Bambu A1 mini which is the very best printer you can buy) and put it to good use by printing an adapter to convert my brushless motor to an edf. Does anyone have plans for a Single edf foamboard plane? Anything would be greatly appreciated. I believe it's a 70 mm.
Help! Single EDF plane?

I have a 1400 kv motor with a 3s 2200 mah LiPo. Do you think that will be powerful enough?

1400kV is not a description of power but only how many rpm it spins for each volt applied.
We need the details of the motor and ideally the maximum amps it can draw.
1400kV is pretty low. On a 3s (say 12V) it would be turning at 16.800 rpm with no load and more like 14,000 rpm under load.. That would do nicely for a 7x6 prop.
Note a 70mm fan is only 2.75" in diameter so it has to rotate much faster to get any meaningful thrust.
Even a basic 70mm EDF will use a 3400kV motor on 3s. It will use a pretty big one like 2842and and will draw 35A.
If you are going to use a low power EDF the airframe has to very light to make up for it. Foam board is light but is not the lightest foam,
