[QUOTE=RCjetdude;n55021 To simulate the gun sound of an A-10 on a card (which I am leaving to the experts at Mr. RCSound) I would envision a sound triggered by a switch and played for the duration of the sound, not how long the switch is active. [/QUOTE]
We're thinking along the same lines, Steve.
With the molds in production, it's just a matter of time, guys and gals. We'll have more clear info and multimedia in the coming month once we get clear of the holidays.

RCjetdude, I love your progress video. Is anyone else making the BrrT sound in their head whenever the trigger is toggled? Or I am the only HogNut here?
This 80mm A-10 has a lot of wing and flies more like a trainer turbine than the smaller A-10s we've sold in the 64mm size. If any of you have flown a turbine Boomerang, it flies a bit like that it terms of weight, penetration, agility, ease of landing. Sometimes it's difficult to make a scale design fly easily in RC scales, while sometimes it's fairly straightforward. This A-10 was the latter. We anticipated some of the upcoming challenges in terms of wing strength and exhaust incidence, having learned from Freewing's smaller 64mm A-10. This saved us time when refining Freewing's 80mm A-10.
Evenso, scaling up pushes the limits of foam, which is why we ended up developing the multi-material wing. Ply ribs, intersecting carbon square rod spars, and captive aluminum receivers. Same as with the F-14 and all our other birds, we've tested the upper limits of this A-10 design so you pilots don't have to. We've folded wings at 130mph, 125mph, 100mph, 75mph airspeeds in steep dives and excessively overcontrolled direction changes. Even the real birds were limited to ~18 degrees directional changes, while we've tested out to 65 degrees in full snap. Build the wing too light, and it won't sustain the forces exerted upon it within the normal intended flight threshold. Build the wing too heavy, and sure it will survive 130+mph dives and full elevator+full aileron input, but then the wing loading shoots up and the rest of the flight experience is poor. So we've gradually and patiently tested the aircraft to find the balance between top speed, wing strength, and wing loading, where the aircraft can sustain the "yanking and banking" forces exerted upon it during normal operation and at the speeds it's powered to fly at, while still having the weight to give it good penetration without being a bear to cruise or land. The result of its cruising efficiency can be seen the in the video's we've posted so far, with throttle at 25%-30% at some points to maintain level flight, and the wing's acceptable G-load is even higher than what you've seen in the prototype videos we've posted so far. Although again, overall we've optimized this A-10 for an RC Jet's performance envelope, not a 3D envelope.
