I forgot to mention that drawings 1 and 2 refer to "static" condition, while 3 and 4 refer to "dynamic". There is no point to edit the post once again.

I don't know for my winding arrows, but the cock looks pretty cool. Difference in surfaces size and shape around CoG, will create forces that will try to rotate the aircraft along any of axis provided mentioned asymmetry exist, moving the focus (aerod. centre) to new position. I ran out of paper for the images 5 and 6, side wind effect on wings. ADDED /edited/: This is the (simplified) situation in the air (aircraft airborne). Situation on the ground is more complex since the aircraft have 3 contact points which also affect the forces distribution around the CoG, which - in this case - resides in front and above the main wheels line. As for the significance of the wind effect on the aircraft, note that every aircraft have strict takeoff/landing wind speed limit, for the desired velocity vector have to be several times larger than the wind vector in order to maintain satisfactory stability/agility aircraft reserve.

Thank you for reporting. We will implement inputs for some of marked "clickables". Note that some of them have no implementation (no practical use) in DCS (e.g. helmet visor heat). Patch will be available in next DCS update. Just for the clarification, some of these inputs were not mapped because they are suppose to be "one time set": set them before you take-off, turn them of after you land (e.g. missiles head heating). Some, unfortunately, have no purpose.

Not entirely correct. Rudder deflection drops with speed. At high M, they are almost impossible to move. This is simulated, and happens gradually, depending on the speed.

Noted, thank you.

All noted. - Cold start broken radio is fixed, pending patch. This was reported in a separate thread, and fixed several days ago. - Radio channels are enumerated 0-19 in cockpit (my local files, checked with Mike also). If they appear 1-20 in the game, it is possible some of the patched textures did not reached the users (for any reason). Maybe I did not get it right - I understand you guys see chnls 1-20 in the pit, correct? - All "old" (now "ancient") missions have been re-saved by me long ago, and uploaded for patch distribution. It is possible that all/some have never been included in the patch. I'll repeat this procedure again.

Sounds are correct. Slewing reticle will become a user-option in next patch.

I can't find toggle mirrors input listed in DCS. MiG-21 does not have it. Are you sure that input is not mapped to the freetrack inputs? Maybe it has something to do with a keyboard layout/language settings?

Noted. (Might not be fixable for all weapons.)

Noted. Meanwhile, concerning the throttle (axis) and the engine response, do you know that you can setup your throttle so that you have improved control on e.g. afterburner settings and e.g. SPS throttle position? Engine response to the throttle inputs can be controlled precisely (to reasonable extent) in Options/Controls/21/Axis Commands/Throttle, and then select and adjust the "User curve".

Noted, will be fixed, however, for the IAS>600 km/h read the manual and Flamin_Squirrel post. Thank you.

1. Second reheat (ChR) can be used on ground. In essence, the engine control system does not recognize if the aircraft is on ground or no - it will measure external pressure (aircraft must be below ~4000m) and full reheat must be on to provide conditions for the proper ChR ignition. Main reason why it is not mentioned/used often are: - increased engine instability on low speed, - irrationally increased fuel consumption. 2. Drag chute in the air ... I will check it. 3. Missing cockpit after the update -> one or more MiG-21 entry Lua files are corrupted or contain some errors. I can't tell which those could be since it depends from case to case, but good place to start inspection could be the mainpanel file.

Noted. "Light" refers to chanel window backlight.

Air bleed doors and aileron boosters test buttons are not implemented at the moment. Since they have no practical purpose in the game, they were left behind early in development... Purpose of these buttons is to test normal operations of air bleed doors and BU-45 hydro boosters on ground, during the aircraft inspections. We will implement them. Type 81 transponder switch is actually SRZO (IFF) ON/OFF switch. We should have mentioned that more precisely in the manual. SOD is ATC/or other ground based radars signal intensifier (you can think of it as a simple transponder), which aids to the ATC crew during the aircraft guidance procedure (inbound, approach, landing, individual aircraft, group, rough - long distance, fine - precise). Unfortunately, both devices have very limited usability in DCS. However, some developers found them useful for ATC/GCI applications.

In that case - I don't need to prove my expertise also.

Concerning the maximum IAS, would you rather want to have irreparable engine or structural damage each time you excess speed limit, regardless whether the game is in the EASY FLIGHT or SIMULATIONS mode? As for the "acceleration graph", I modeled accelerations according to telemetry data retrieved on multitude of real aircraft test flights. Acceleration time from 0.5 to x.x M (depending on the engine setup) is almost perfect match to the averaged data set I have, and data itself vary from aircraft to aircraft a bit; they also deviate from published data a bit, sometimes for the better, sometimes for the worse. Concerning the graph itself, there are other graphs which are more illustrative to that problem. In general, my impression is that the finesses are represented here as "horrible" which they are not.
