[changelog at the bottom of the page]

"Satan's Buzzsaw" is aptly named on account of its twin circular-saw shaped propellers... Satan, because it's one hell of a ride to be sitting in front of a 1600HP supercharged V8 while sitting on top of the prop-shaft that runs between your legs, and then having to stare out the cockpit at two menacing looking props! That, and roughly 666mph is near its low altitude speed :P (At least in earlier revisions; it tops out just shy of 700mph when horizontal.)

Definitely qualifies as being Experimental class. It doesn't have the best pitch rate that I'd like, which makes it hard to slalom. So the Krakatoaa spires are not easy, and racing through any canyons is kind of off the table as well. It's well behaves, otherwise, as I took my time to balance it out as best I could.

Country of Origin:
Australia
(crazy, and fast... two key characteristics of an Aussie!)

TAKEOFF:
Easiest is...
1) Lower Trim its Max
2) Max Throttle
3) @250mph it will lift off for you
4) Retract Gear
5) Raise Trim steadily over the next 15 seconds or so until it's just about back to Neutral (middle). Just a slight amount of Negative Trim is needed for level flight above roughly 550mph; at least for anything below 10K/ft of altitude.

Alternatively...
At 125mph you can fully pitch-up to take off slightly sooner at 200MPH, otherwise everything else applies.

LANDING:
1) Cut throttle to 0% well in advance of runway
2) Lower Gear and Lower Trim to Max
3) Stay fairly high above the runway until you are much closer; Airspeed is probably still 350mph or more.
4) Max VTOL to deploy main Airbrakes
5) Once you're very near the end of the runway, start a gentle dive at the runway (lawl, right?) and hard pitch up when you're halfway to the ground to put it into a stall at roughly 200-250mph.
6) Apply Brakes to deploy Secondary Airbrakes, once you're pitched up a few feet above the runway, (hey... it could still use a 'chute, in my opinion! lol)
7) Keep brakes applied until you've negotiated a soft contact with the runway, and continue holding the brakes while you say a prayer to the Lords of Friction to get you stopped before the runway completely runs away, nosing you into the grass and grenading the prop blades...

NOTES:
-The V8 is not actually used to power the propellers, it, itself, is simply for looks -- although it does genuinely have 1600HP, which I uploaded separately in case anyone wants to use it. (it's in my profile)
-Its intake and exhaust both function! There are two micro-Rotators inside the center of the butterfly valves on the orange air scoop, and a 0-power VTOL engine inside the Supercharger which is what allows the VTOL Thrusters to produce visual flames. Again, their VTOL Engine has zero power, so none of the thrust comes from those 8 "exhaust" ports! :)
-Yes, each propeller is 1000HP and 1000+1000=/= 1600 lol Shh.
-It will survive shallow encounters with the water no problem. Even extreme encounters, if you can manage to maintain enough speed after pulling up to exit. It's fun to skip it across the water though :P
-Propellers are, unfortunately, not Contra-Rotating, and while that is what I would've liked, it would mean disabling the blade's Auto-Pitch control and setting a fixed pitch. May work out a Mk.Vc -for Contra- to do that... But Mk.Vb was mainly about Braking so that you could land. Clever, right? ;) ;)

FIXES/IMPROVEMENTS MADE TO ORIGINAL Mk.V:
1) Corrected "Auto Throttle" on Pusher engine. (forgot to disable after testing to see what it did)
2) Corrected anomalous left Wingtip that somehow became non-symmetrical from the right side.
3) Addressed ever so slight auto-roll to Right while in flight (set right flap input to 0.0001 + Roll; perfect now) .
4) Addressed tail being too light, which solves...
——a] the loss of steering at anything above roughly 20mph
——b] needing so much Trim in flight to keep the plane level
5) Addressed the fact it likes to fly... which makes LANDING a huge issue. Accomplished by:
——a] adding an air brake, then adding another one... then adding two more...
——b] changing the rear-front wing --wings are made up of 2 wing-parts and a rectangular chunk of fuselage-- from Semi-Symm to Flat Bottom; seemed to help with stall speed (maybe? also seemed to improve top speed by a lot) .
6) Tweaked the Pitch control surfaces to assist in its incredibly sluggish pitch rate; slightly increased rear surface size and max angle, whereas front involved a slight decrease to max angle.
7) Tweaked front Gear suspension to assist with SP feeling it necessary to drop-spawn you on runways, causing any instant-throttle applied to break prop blades; also improved landing, so yay!
