Revive the UDF in a model aircraft!!!

[WC3POchannel10A]

Forget the F-18. I want the UDF!

lije a turboprop for me is better a jet engine or a turbofan like at 1:16

Anyone else noticed that that plane has conventional turbine engine on the other side? o.O

An awesome concept introduced in early 80's. most fuel efficient and best performing engine! should be brought into production. technology has changed since 82, just think of the overall performance now.

@84Dirtboy GE incorporated a lot of the technology from the unducted fan designs into their GEnx engines.

@superskullmaster

You don't have a clue. This is what GE Aviation is planning for some of their future engines.

Fly past at 160 knots clean configuration?

Thanks for adding this video. I was there and now I can direct people to this moving and audible image. I always say, it was no louder than a small helicopter.

[SERVICEOFHUMMANITY]

not only does it look great they sound fucking amazin :D lol

[10Kingboy10]

i hope the future wont have these kind of engines .. :( i want future engines look like they r now but more efficient! and not this kind of form..

[superskullmaster]

@10Kingboy10 you must be retarded. This shit was killed by efficient high bypass turbofans, strict noise regulations and reasonable fuel prices. Unless you live in 1988 while the rest of us are in 2011.

quite a steep looking takeoff

[nurvus]

@falaqdad15 Ever heard of a high performance take off? It is an airshow after all....

[falaqdad15]

@nurvus nah not really, i really don't know much about this. it just looked steeper than most airport takeoffs.

[dot13badj]

That was an impressive TO!!!

[uutdordt26]

This is the first time I really can hear the sound of the UDF. Very nice video!
