Yes guys. Why all of them have two EDF? Because big MiG has two engines?
No way! I have built MiG-29 with one EDF.
Here is a maiden flight.

MiG-29 single EDF -maiden flight (3 min 31 sec)

EDF is hidden between engines in external fuel tank.

Wingspan: 105cm (42")
Length: 143cm (57,2")
RTF weight: 1500g
FMS EDF 70mm 12 blades
Accu: 4S 3000mAh

Now, after successfully maiden flight I can work more to make my MiG more scale.

Plans are in post #38

The main reason, why I wanted use one EDF was weight to fly. All kits have two EDFs and they are very heavy, so retracts are needed, and a lot of reinforcement so special runway is a must.

I fly over meadows and fields so the best method to take off is hand launch, even without bungee if it's possible.
I have built my MiG from depron 3mm, 6mm and 9mm. The only reinforcements are carbon tubes in wings and pine stripe along the fuselage.
The size of plane is a compromise between size and weight, yes I love big planes . Big and light plane has a low wing loading factor and low minimum speed.

Here I want to share with you build process, How I made this beauty. Maybe I will inspire someone.
Generally model is made from modules:
Front fuselage
Rear fuselage
Wings
Engines

Front section, made from 5mm and 3mm depron.
This part weighs only 105 grams -like chocolate bar

Wings with profile hmmm.. HMP - hand made profile .
You can see carbon tubes as a reinforcements.

Rear fuselage, centre wing section.
Made from 6mm depron. There is only one pine stripe along the fuselage, no additional reinforcements.
The stiffness is the result of tension of sheathing.

Table size is 22" x 36"

Before I closed fuselage I added additional cables for navigation and afterburner lights.

Engines are made from 9mm depron, they have to be strong. MiG will be land on them.

EDF Mounting. First I had to cut a little fuselage to mount EDF little deeper.
Then I glued EDF and covered all to make them as a part of external fuel tank

And finally ready to fly.
I added cheat holes for EDF, just in case, for the maiden.

Hi robertus, BEAUTIFUL work on your Mig-29 !!!
I had the same idea for powering a Su-34. Mine plane is a micro (20mm edf) but I'm taking the same approach as you.
I started this plane last year and then I got sick and everything stopped.
I'm just now starting to feel better.
I read this thread and and it gave the inspiration to get started on finishing my plane ....

Thanks !!!

Very, VERY nice work, Robertus!

I was going to do this on a micro Guillows F14. Your model looks the business, you wouldn't know it was a single set up. Well done !

Robertus, would twin 70mm edfs fit or twin 64mm edfs?

I think 64mm will fits better. 70mm as you see is quite big and I had to cut some foam when mounted it.

Bookmark! Thanks Robertus...finally you make this beautiful jet....

Thanks. At the moment I have other tasks, so be patient for final painting, canopy and afterburner LEDs.
In the meantime I can share my tests about LEDs for afterburner.
It is built from two servos and one RGB led, as a POC.

Test dopalacza EDF z LED 01 (1 min 32 sec)

I use red and blue color.
