best MiG-21 Mobile Friendly

Simple but mobile unfriendly

Could you make a Phantom?

@Whills question if your available when will you post your next aircraft?

@rorrE well, "tailplanes" is the a variable name that I defined in the variables list, you can check that list by clicking the variables button just next to the play button in the designer.

very cool plane, lots of details considering it's pretty mobile friendly..
also one question (ik it's been a year but) how did you do the horizontal tail wings??
I saw the ft codes on the rotator it just said tailplanes.. does that actually work??

Absolute BANGER design, I love flying this thing so much!

beautiful plane

Nice and simplistic, love it!

Watch me ruin the hell out of this plane

@Mig

Waiting For SU 27

Great 10/10

Comrade

This plane is cool btw how u can make a radar?

waiting for su27

@Sputochka Sure :-)

Hello! This is the greatest Mig-21 I've ever seen!
By the way, may I use your HUD and radar?

mmm yes, "simple"

@Whills ohhh I get what you mean. And yeah I use a calculator which just automatically tells me the mach number at a certain altitude I put in. I also have a mach calculator display that takes altitude into account. That’s why I find it annoying when people say that a planes top speed is a certain mach number but they don’t say the altitude it reaches that number at hahaha. My issue with high and low altitude though is more that if I build a transonic aircraft that can reach 0.9 mach at 5000ft, but in real life can’t break the sound barrier in level flight, in SP the plane will exceed mach 1 when at high altitude since I don’t think SP’s air model can model the issues that occur at transonic speeds. Would be nice if fuselage tapering for the area affect would be modelled on SimplePlanes but sadly such a thing isn’t possible

@Mustang51 Actually I am using this expression to get the realistic mach number, I use it in the cockpit label. For example, you can just put a text label and then copy and paste this into the text field:
Mach: {TAS/(Altitude<11000?(340.3-0.0041*Altitude):295.2);0.00}
By checking this label, we can know the plane's real Mach number.

Sadly in this game, we can't use FT to control the engine thrust multiplier. But since Jundroo already simulated the effect that the air drag and engine thrust drop as the altitude goes up, I think as long as we can get the drag point right, then the top speed at both low and high altitudes will be realistic.

I think the main reason we find it hard to balance the top speed is that we didn't calculate the Mach number correctly, I used to just divide the TAS by 340 (so does the Jundroo's official planes !), which is quite wrong. In fact, at 15,000m, you only need to get about 2,100 km/h (TAS) to reach Mach 2, but most people think they have to make the speed as high as 2,450 km/h, which is actually way too fast.

@Whills oh I never thought of using FT to control its max speed! Do you just add that to the engines and in what part would you put that in? I’m far from a pro at FT hahaha. But this would be a really nice input because at the moment, I feel like I can make my planes either only realistic at low altitude or high altitude. With a code like this, the max speed can be realistic at both

@Mustang51 That sounds a great idea, I will surely give it a try. I think increasing the drag point a little bit might also be helpful (around 1500 I think). This plane is too fast at current drag points. When the the plane is at higher attitude, it is easier to achieve high Mach number. Since the speed of sound will drop below 300m/s at 10,000 m. If the plane's GS Is 300 m/s, then that's mach 0.88 at sea level but mach 1 at 10,000m. I use this funky tree express to roughly get the local sound speed: (Altitude<11000?(340.3-0.0041*Altitude):295.2)
