hello modelers
i am trying to build a legendary mig 29...
here is info about the aircraft i am trying to build.
weight: 12.5 pounds to 15 pounds max
length: 216.5 cm-- 85.2362205 inc
wingspan: 142 cm-- 55.9055118 inch
Wing aspect ratio: 3.5
this aircraft should have two ducted fans installed in the back. can someone give me information on what size of engine i should purchase. and possibly a url link to where i can purchase it?
another question is, should i purchase two engines or can i operate two ducted fans with only one engine. i dont think that latter is a possibility though.
please do inform me on your opinions and comments.

Hi Taylan,
Sounds like a neat project.
I would think that two engines, each of .60 - .90 size (closer to the .60 size probably) would be about right for that size/weight ducted fan powered jet.
I do not know of anyone who has run two fans off one engine.
Perhaps someone more "Jetty" will reply with good advice on brand/type/size engines and fan units for your project.
I did find some twin engine RC ducted fan jet kits on the web, but they had finished weight of 25 - 30 pounds and were powered by twin five inch fans with .91 or larger engines.
thanks for the ınfo. ıt was useful for me.
as ı browse the sites ı could not fınd engines wıth such partıcular specıfıcatıon as .60 sıze.
can you tell me what .60 is of a measurement? what should ı search for to fınd a .60 size engıne?
thank you very much.

Taylan,
No, that engine would not do for running a ducted fan unit.
It would be for a regular prop airplane.
Engines for powering ducted fans are special units made to run high RPMs and put out plenty of power.
I will try to get some candidate engines researched for you and reply back here soon, later on tonight my time.
