Basically, Flat bottom and semi-symmetric create lift even at 0 degrees AoA, while symmetric needs positive AoA to produce it. Flat bottom creates more drag than s-s, which is more draggy than symmetric. flat bottom has a higher critical AoA than s-s, which has a higher critical AoA than symmetric... and so on
nacaprop can only be used through overload and is the airfoil the props in the game use
Not really an answer to your question but you should use angle of attack, not airspeed, because a plane can stall at any speed and at any attitude.
The symmetrical airfoil stalls at around 14-15 degrees, semi-symmetrical at 16-17 and flat-bottom at 30 degrees or something like that.
IAS > 5 ? clamp01(-AngleOfAttack > 16) : 0
this would work perfectly, just change the number for the correct one, if it turns on too early increase it by a little bit
Hey, it looks like someone from 2014 went to the future and stole your photo and model

Do you really need upvotes so badly that you have claim you made things you didn't? Same with the other mig-25 post
(Only for jet powered aircraft)
Accurate maximum thrust can be achieved by dividing the real thrust by the thrust of the SP engine you're using and obtaining the correct powerMultiplier value that way.
For props it's basically trial and error because of the many things that affect their thrust
Something I'd like to point out is that the elevator input you showed might work but isn't really a good method. I personally prefer attaching the main wing piece to a rotator or using a control surface, if it works, as these would actually increase lift and not just pitch the plane up
Very well explained post, I hope it helps lots of people
@PointlessWhyshouldi The SportStar and EuroStar are a family of a two-seat, light sport aircraft (LSA), manufactured by Evektor-Aerotechnik of the Czech Republic and powered by a Rotax 912ULS, 100 horsepower (75 kW) engine. The SportStar is an all-metal design made from anodized, corrosion-proofed aluminum. The airframe uses a pop-riveted and bonded construction, which the company claims will improve fatigue characteristics and result in a longer service life. The company also claims this construction technique results in better crashworthiness, the elimination of rivet zippering in an accident and quieter in-flight noise levels due to the elimination of oil-canning and flexing.
@PointlessWhyshouldi The Pratt & Whitney J57 is an axial-flow turbojet engine developed by Pratt & Whitney in the early 1950s. The J57 (first run January 1950) was the first 10,000 lbf (45 kN) thrust class engine in the United States. The J57/JT3C was developed into the J75/JT4A turbojet, JT3D/TF33 turbofan, and PT5/T57 turboprop (of which only one was built). The J57 and JT3C saw extensive use on fighter jets, jetliners, and bombers for many decades.
The North American F-100 Super Sabre is an American supersonic jet fighter aircraft that served with the United States Air Force (USAF) from 1954 to 1971 and with the Air National Guard (ANG) until 1979. The first of the Century Series of USAF jet fighters, it was the first USAF fighter capable of supersonic speed in level flight.[4] The F-100 was designed by North American Aviation as a higher performance follow-on to the F-86 Sabre air superiority fighter.[5]
Adapted as a fighter-bomber, the F-100 was supplanted by the Mach two-class F-105 Thunderchief for strike missions over North Vietnam. The F-100 flew extensively over South Vietnam as the air force's primary close air support jet until being replaced by the more efficient subsonic LTV A-7 Corsair II.[6] The F-100 also served in other NATO air forces and with other U.S. allies. In its later life, it was often referred to as the Hun, a shortened version of "one hundred".
In January 1951, North American Aviation delivered an unsolicited proposal for a supersonic day fighter to the United States Air Force. Named Sabre 45 because of its 45° wing sweep, it represented an evolution of the F-86 Sabre. The mockup was inspected on 7 July 1951, and after over a hundred modifications, the new aircraft was accepted as the F-100 on 30 November 1951. Extensive use of titanium throughout the aircraft was notable.[8] On 3 January 1952, the USAF ordered two prototypes followed by 23 F-100As in February and an additional 250 F-100As in August.
The YF-100A first flew on 25 May 1953, seven months ahead of schedule. It reached Mach 1.04 in spite of being fitted with a de-rated XJ57-P-7 engine. The second prototype flew on 14 October 1953, followed by the first production F-100A on 9 October 1953. The USAF operational evaluation from November 1953 to December 1955 found the new fighter to have superior performance, but declared it not ready for wide-scale deployment due to various deficiencies in the design. These findings were subsequently confirmed during "Project Hot Rod" operational suitability tests.
First of all, congrats on 100k!

Aesthetic ailerons are inverted, acceleration is unrealistic, airbrakes are too powerful, max speed at sea level is above the real thing's max speed, but it looks really good, so nice plane I guess :)
@Belloaka round(GForce*10)/10 displays GForce with one decimal place, round(IAS*3.6) displays IAS in km/h, round(rate(Altitude)*10)/10 shows rate of climb in m/s with one decimal place...
The commands I most use are: DebugExpression [enter input here] - useful to see GForce, AoA, testing FT formulas.... ClearDebugExpressions - self explanatory //MainCamera>Camera.set_fieldOfView [number] - for FOV adjustment say ["text"] - only way to send messages in multiplayer

+1x is input, a is minimum value, b is maximum.
if the rotator is set to 180, 1 is 180 degrees
