Yeah, I liked Agent Coulson in the movies, but unfortunately, it would seem that dying turned him a bit touchy-feely, at least for a suit. Ditto on the kid's-show dialog... I mean, I'm not asking for Shakespeare here (or the Sopranos), but come on... Same for the raft-in-the-hole... Also, maybe this is just my having worked with UAVs/quadrotors too long, but: toy-looking quadrotors. Having quads isn't inherently bad, but these seriously look like something you buy at Toys R Us. Given that they're in the same world as Stark, the helicarrier, etc, you'd think that they could have tiny Oblivion drones, or anything that doesn't look like what they've got. And an interface that isn't a crime against humanity. A 3-panel folding touchscreen? Which dedicates an entire screen to a picture OF THE AIRCRAFT YOU'RE FLYING?!? -- Of course, the Helicarrier had something similar, so... Maybe that's just being consistent. Anyway, one more for me, I had planned on doing the 4-episode trial, but at this point, I don't think I can take more than three. -Luke

Yes, except the latency on BLOS links can be pretty bad, and the current generation of gimballed sat-link antennas can't keep up with aggressive maneuvers... So, until you either take the man out of the loop, and go fully autonomous, or come up with some entirely new ultra-high-bandwidth, low-latency BLOS links, going to a UAS won't buy you an automatic maneuverability improvement. ~Luke

Thanks! Keep in mind, this is over 5' long... I've never done casting, but I'm guessing the exotherm would play merry blazes with the final product. ~Luke

Thought you guys would appreciate these... 1/12th scale, 3.5 lb estimated AUW... Getting closer to flight-testing, but still a good few months out. ~Luke

You're right, keep in mind the tops of the nacelles are not fitted/glued in place yet, so the slit intakes will be lower profile when all is said and done. They're only about 3/8"" deep, when everything is fitted down correctly. (I based my CAD model on the colored schematic you posted, with modifications up front to turn it back into a UCAV.) The connector between the TARPS pod and the nose isn't installed yet, but will be there. I'd estimate I'm a good 2-3 months away from a the maiden flight, so there's a lot of stuff left to do. Like I said, this is the UCAV (FRX-99 RAFE)... Thus the curved channel thingy. I figured an RC model of a UCAV had a certain novelty/irony to it... Maybe I'll even drop a TWOG autopilot in it, and actually make it a UAV. ~Luke

Re: the chin scoop... Yeah, that's what I figured. Just seems like a lot of drag. The Platz is a resin kit, right? ~Luke

No worries, Sean, this is definitely a one-off. It's actually not the ram-intake variant, which would have the two additional inlets above the top slit intakes, as well as flatter nacelles. I'm going for the 'vanilla' FRX-99; note the curved front intake channel, as opposed to the squared-off one the FRX-00 has. Also, it's a prop-job, I'm after strong vertical performance, so EDFs were out. I know, I know.... But come on, 5' long, custom retracts, 1:1 thrust/weight, and no vertical stabilizer... I had to cut corners somewhere! ~Luke

Nice! That's the Bandai 1/100th, right? Actually, maybe you can help me out a bit... I'm still stuck on what the chin scoop is supposed to do... Seems like it just floats there? Are there any intakes inside of the scoop that would actually get some air to the engines? Mine doesn't really fit on my workbench... But it's coming along... Slowly. ~Luke

That is pretty neat. The vertical destabilizer is definitely an unusual touch. ~Luke

Nope, variable-incidence wings got cut from this build... Issues with the forward-swept wings and actuator loads. (And airfoils, and weight, and space, and.........) Still hoping to do the flip. Regarding reversers, I rest my case. (Thanks for the info David.) If an airliner can use high throttle in reverse, I'm SURE the FRX can. Speculation on the interface (slaved reversers on the HOTAS, etc.) is irrelevant, since whatever it was, it allowed the throttle setting to stay constant while the reversers were actuated. Just chalk it up to software/FBW magic. Maybe something like in YS Flight. The point is, for a work of fiction, there are bigger issues with that scene than something as mundane as retracting the thrust reversers. More on-topic: I've gone through a few different iterations of retracting landing gear... Even though it's not exactly accurate, I've returned to a canted-axis (SU-27 style) design. I built a two-axis unit, but to get the wheels into the bays (without hitting anything) was insanely difficult, whereas the canted axis swings both up and towards the centerline, making it much more suitable. I'll post pictures shortly. ~Luke

Ok, wait..... Yes, drama, and all, but.... Thrust-reversed turbines do NOT spin in reverse! Thrust-reversing occurs as fast as the reverser buckets can deploy/retract. Of all the problems with that scene, spool-up times are probably the lowest on the ladder... They could have been running at significant throttle setting with the thrust reverser buckets deployed, and just holding the brakes; given the absurd thrust/weight ratios (vertical acceleration to supersonic from a hover in a matter of seconds), hovering would occur at what, 33% throttle? ~Luke

Post-stall landing isn't that crazy... The landing was similar (in principle) to the tests performed with the X-31, only the variable-incidence wings allowed the FRX to remain relatively level prior to touchdown. The X-31 on the other hand had to fly with a 20+ deg. nose-up attitude, derotating just before touchdown. The takeoff... Yeah... Never did figure out how they didn't scrape the bottom of the nacelles, as they fell off... ~Luke

Got start on the sheeting, and opened a thread over on RC-Groups: http://www.rcgroups.com/forums/showthread.php?p=14063588 ~Luke

You mean fall off a moving boat backwards, hover, and then climb out vertically, don't you? Gear arrived yesterday, and the frame is all glued up. Now for the tricky part: sheeting. ~Luke

Sure, once I get it... It's shipping from Hong Kong. About 100% cheaper that way, even counting shipping. Got it coming via EMS, though, so it shouldn't take too long. ~Luke
