Greetings All -

I photographed this model of the Vought/VFW submission for the T-37 replacement [Vought V-538 - Added by Admin] while visiting/volunteering with the Vought Retiree's Club, keepers of the Vought historical archives. Anyone have info on other submissions?

Enjoy the Day! Mark

It was a development of the RFB Fantrainer, called "Fantrainer 400" and
proposed in 1979. As the short article from FlugRevue 10/1979 shows,
another version with side-by-side seating was considered, too.

Can anyone confirm the designation Vought V-539 for this display model?

By the way,

the first aircraft for Vought/VFW called V.538 and the second
called V.541.

In " Luftfahrt International " 1/81, H.J Meier wrote about the LTV/VFW/RFB entry to NGT contest :

- the one fan entry is the V-538
- the two fan entry is an early V-539 design
- the definitive proposal is the V-539 design shown in the 3-views

Splendid. I'm still trying to find the difference between the V-538 and V-541 proposals. They are supposed to be pretty similar, but all the pics I've seen so far seem to show either the V-538 or the V-539 proposal. The only pic labeled "V-541" is most probably mislabelled as the picture seems to depict a V-538.

Could anyone here shed some light on this question? Thanks.

Thanks a lot Bill! The presence of the V-533 design (similar configuration to the T-37B) called for a renaming of the topic.

Instead of mentioning "V-533 / V-538 / V-539 / V-541" in the title I opted to leave only the name Eaglet since it was officially given by Vought.

Interestingly the very same name also circulated at the time for the Fairchild FRC-225, which "won" the competition as the T-46A. Perhaps the Air Force, not the companies, originated the name of a small eagle to evoke an advanced trainer preceding the F-15 Eagle in the pilot's progression? Just a thought

Nothing really new to add as far as information.
These are better scans/color scans of information previously presented.

I was lucky to win this on E-bay as in over 40 years of collecting the Vought Eaglet had eluded me. It had issues big time. Painted in trainer white, the paint was bubbling and chipping, and it was a very poorly executed example of the usually good Vought model shop models. I decided to redo and decided on the attack version. The only thing to finish is the wood stand this weekend....... Enjoy.

Here is a recently found drawing of the V-539 from early May 1980, that is slightly
different than other drawings in this thread. The intakes are in the wing leading
edges and the "strakes" around the fans. The length is a little shorter than other iterations as well.

Something new for the conversation is this mid-wing twin boom gull winged Eaglet!
It also shows provisions for under-wing fuel tanks or stores.

This would make a great WHIF modeling project.

I think your asking if L12 was an always used designation for the Eaglet, no it was not.
L12 was a prefix for Advance Products drawing numbers, nothing to do with the model number of the design.
There are L12-XX-XXXX drawings for the A-7 and a number of different projects including the Eaglet.
