Nope The Diablo motor is actually going back in. I just get a kick out of the size and weight of this thing.
Would have been funny to stick a fiero motor in the Diablo and used the Lambo motor in a Diablo kit car!! That would have screwed em up on the lambo lounge forums!!!!

Btw, there's one of those Vipers that drives around my hometown. It looks sweet. It sits so much lower in real life, and it's wideness makes it look like a predatory animal poised to attack.

that's what she said, I know.

I was gonna say, I've never heard of an "XD" version Ka-50... They are pretty cool that's definitely for sure, but I have no desire to fly a coaxial / tandem rotor helicopter... Main reason (aside from being unconventional designs) is if there is a malfunction with either set of main rotors, the autorotation all capability is SEVERELY degraded / impossible... Where as if i have a malfunctioning tail rotor (or loss of tail rotor thrust), I still have a few options to land safely (relatively atleast)...

The Ka-50 (or even our Ch-47 chinook), with its unconventional design could even be compared to the US Marine Corps V-22 Osprey. They are all By that I mean if the Osprey is in a vertical flight mode (ie, engines adjusted "up" for very low speed forward flight / hover) and they suffer an engine failure, everyone WILL die. There is no autorotation all capability if thrust is lost / compromised on one of the lifting surfaces. Both have to work together perfectly to keep it in the air...

I'm posting this from the iPhone in the field at the moment so not sure if I fully explained myself or not :-/

You know I'd love another Viper but I'd pull the trigger on a brand new one as my first choice (640hp bone stock and styling that goes back to the first GTS - close to my previous 97 GTS)

I would have to get another Mustang. 400 hp and 9000 RPM redline from a 5.0 liter odd fire V8....nothing sounds like that anywhere.

EDIT: that is tuned of course. stock redline is a wimpy 7000 rpm

No, I understand what you're saying. This is probably exactly why the engineers behind the Kamov developed the first ejection seat for a helicopter in the first place!

Ejection seats on a helo...Cool! Whats it do blow the main rotor first...? or shoot you out the side?

Yep, pyro charges on the rotors. Here is Force_Feedback's post on a forum...


Yes, the post above has the right ejection seat mentioned, the official designation of the system is not K-36, but "Zvezda K-37-800 rocket extraction seat". You can hardly can call it an ejection seat, because it lacks any kind of catapult (the thing that pushes the seat out before the rocket engine ignites, also known as a ROCAT).
On the Ka-50, first each bolts (2 of them per blade) near the rotor hub are detonated, removing the risk of any serious harm caused by thin chunks of plastic travelling at 600 km/h, also known as rotors. Then the upper glazing goes, along with the upper hatch, when that is out of the way, the rocket (that white thing on the backside of the seat, behind the headrest) is ignited in low power mode. The rocket itself has deflected nozzles, to ensure stability by spinning around. After the extraction cord has reached full length, the rocket motor fires in full power mode, pulling out the parachute and pilot by the shoulder straps.
The direction of travel of the rocket is slightly forward to compensate for high speed and zero-zero ejections.
The whole sequence takes approximately 1.5 seconds, which is significantly more than that of "modern" ejection seats, which is about 0.6 seconds. The system allows for ejection in the full envelope, and at 50m when inverted.

The body of the Ka-50 ensures survival for the pilot if the vertical crash speed does not exceed 12.5 m/s, or something in that vicinity, I'm not sure about that speed, it might be higher.

Except the CH-47 can autorotate safely... The V-22's lack of autorotation capability (and it's several crashes) is it's main negative feature. The rotors are so thick and short, they're more like props on a traditional aircraft. On a CH-47, you can control your decent by pulling collective even w/out power and it will work much like a single rotor aircraft and rapidly slow you down before touching down.

You're missing the point I was trying to make... That point is that if both lifting surfaces are not in harmony with each other in the ch-47 you will not be able to autorotate (there is no autorotational capability in the v-22, so an engine failure with the props vertical means certain death)... By harmony with each other I mean if the pitch control links become effed, the rotating swashplate draglink fails, or a severance in the drive shaft between the front and rear rotor discs, autorotational ability is severely degraded if not completely removed.

Pardon the spelling errors. I'm posting this from my phone, in the field where it is currently just above freezing, so I don't have the patience to go back and correct them, you'll get the idea.

Basically: conventional helicopter design (single main rotor combined with counter-torque tail rotor) is much safer than an unconventional design such as the CH-47, v-22, etc... They may have abilities that exceed a conventional rotor system, but I know which I would rather (and DO) fly into battle...

Thread Jack Over... Sorry PooK, I was just trying to make sure I was clear... I know the internet can be a challenge to get a point across at times and rotary-wing flight is definitely one of those points that is hard to talk about over internet... Really I only expect other helicopter pilots to truly understand what I'm talking about so don't anyone go taking offense by that. The simple fact is just because someone has a rough idea how a helicopter operates does not mean they fully understand rotary-wing flight. Hell it took me 2 years in Army Flight school to learn, and we produce the best helicopter pilots in the world (but I'm bias )...

But back to the point... I do actually like the design of the bar on the track Atom pictured further above in the thread (and now re-posted in my post, only because I'm FINALLY at a normal computer and not on my phone)...



Are there downfalls to this design PooK? (Strength, visibility, ergonomics of getting in and out, etc?)

Other than ingress/egress any additional bracing to the main hoop would be a bonus provided its not to close to your head and wrapped with some good SFI foam.
Problem is even SFI foam without a helmet will ring your bell, maybe permanently!
Then there is the visibility issues when its on the street. A wrapped 1.5" tube is about 3" in diameter ok for the track, not so good for the intersection.
