T-38 Talon Park Jet

Here are BETA plans for the latest member of the Park Jet series, the Northrup T-38 Talon. This design is very similar in concept to the F-18 and F-15 Park Jets, and uses the same construction methods and recommended power setups. Like the other jets, itís intended to be a true park flyer built with simple construction methods and using inexpensive and readily available components. Here are the specs:

Wing area: 218 sq in
Span: 28.2 in
Length: 45.4 in
Weight RTF: 15 Ė 18 oz
Wing loading: 10.9 oz/ft2
Motor: GWS EPS-350 with C gearing (or brushless equivalent)
Battery: 1200 Ė 1500 mAh 11.1V Lithium-polymer
Prop: 8x6 (EPS-350) or 9x6 (brushless)
Flight controls: Wing flaperons, full-flying horizontal stabilizer

The general wing planform and tail moments of this design are fairly similar to the F-18 Park Jet, so Iíd expect the T-38 to fly similarly. However, because the real T-38 has such a small wing area this design also has a smaller wing area than the F-18 Park Jet (218 vs 254 sq in), making the wing loading a little bit higher. Thus, the T-38 will be a little hotter than the F-18, but if the weight is kept low it should still qualify as a park flyer.

The reason Iím posting beta plans is because these plans have been done for nearly a month and I havenít had time to build it yet, and with the holidays approaching I wonít have the time to build it for at least another month. And since many fellow Ezoners have expressed strong interest in building this jet, I decided to go ahead and post the beta plans now and let you guys help work out the kinks!

Please note that because these are beta plans they may have errors and that the CGs and control throws shown are untested. Thus, if you build this please take note of any errors or misalignments in the plans, and most importantly what CG and control deflections your finished model flies best with, and let me know. After I collect a list of improvements, Iíll update the plans (if I don't build my own copy sooner!). Both tiled and non-tiled files are posted below, as are previews of the plans.

Enjoy, and post pictures as you build this!


EDIT #1: (Aug 6, 2005) I finally had a chance to build this bird, so I've attached some photos below.

EDIT #2: (Aug 21, 2005). I updated the T-38 plans to fix several errors and include several design improvements, and also developed a new illustrated construction guide for this model. These are available in post #872 of this thread (link below):

Thanks Jet for the official release of this thread. I had a chance to get a head start on this project. This plane does handle similarly to the F-15. However, It requires speed! This is not going to float around like the F-18, 15 foam planes. I used a axi 2208/34 with 9x6 SF prop. Controlability became an issue at low speeds. This baby lives for speed. I have some c.g. and rebuilding issues to do prior to my next flight. Seeing how my first attemp went off with mixed results.
