In a restricted external view server like 104th, if you press Ralt-J once, your plane continues flying with the AI and the camera view keeps floating in the sky. If you do that while in ramp, the view goes above the pilot and you cant return to the cockpit unless change the slot. pressing Ralt-J twice was the only way to make the SU-27 trim works in 1.5.4! Log attached dcs.rar

I know, my post was a joke mate!

Yes GG told that ED was working in the guidance, because is someone tell me that this is the real ER flight model, I will think again as I posted before, that russian scientists are dumb! and those working in the military the worst!! :chair:

Good test Darkfire, unless the variable LifeTime inside the missile_data.lua is set to 60, the ER missile should hit the target, you had lock all the time until 13:14, but the missile was fubar anyway. And if you notice you launched the missile at 52.5 km away, and even coming from above the missile could not reach 40 kms with a good speed!

Yes, is the same in DCS for R-27ET KillDistance = 11.0,

Someone posted a solution and it works, maybe give you a clue what is happening, was pressing Ralt-J twice (the key to change of aircraft), after that, the trim began working perfect, including the stick to trim.

All launch were tested unguided in overwrite mode, the R-77 max speed was ok, reach 3.9982 mach (4301.4898 TAS), the problem with the R-77 is that began bleeding speed too quick while in transonic, and should be in subsonic!.

I did the test many times with friends with the same conditions, we were flying at 10,000 MSL, 900 km/h, head to head with no change in speed and course, tha max speed of R-27ER was match 4.2, 4527.88 kph

I dont have to post anything is ED who assume that 4.5 is not the real speed not me!

Can someone post here a single page of a real R-27ER russian document (or translated/exported) contradicting the 4.5 mach that all analyst post in their web pages about the missile? in that case, I will take what you post for real!. AFAIK, the 65.5 km range is against a fighter size aircraft flying at your own altitude (in this case a maneuverable target), and for bigger aircrafts can kill at 90km

Reading what you post, mean that Russian scientists are dumb, they never discovered or built a decent wind tunnel and were coincidentally the first to reach the cosmos, and have the best rocket engines by sheer coincidence, they sent the more stupid guys for the military! ohhhh god!!! If the manufacturer say their missile reach 4.5 mach and +90km range is with the missile drag/weight already calculated!

Yeah, you're right

R-27R/T Specifications Weight 253 kg (558 lb) Length 4.08 m (13.4 ft) Diameter 230 mm (9.1 in) Warhead blast/fragmentation, or continuous rod Warhead weight 39 kg (86 lb) AIM-120 Specifications Weight 335 pounds (152 kg) Length 12 feet (3.7 m) Diameter 7 inches (180 mm) Warhead High explosive blast-fragmentation • AIM-120A/B: WDU-33/B, 50 pounds (22.7 kg) • AIM-120C-5: WDU-41/B, 40 pounds (18.1 kg) RVV-AE (R-77) Specifications Weight 175 kg (R-77), 190 kg (R-77-1) Length 3.6 m (R-77), 3.71 m (R-77-1) Diameter 200 mm Warhead 22.5 kg HE fragmenting (R-77) We should notice one thing, the AIM-120 is lighter, but the ER/ET speed is higher!, 4.5 mach vs 4, and the ER/ET have two stage motors in total have more burn time than AMRAAM. You can use several software to calculate drag, speed or whatever for missiles, like this one: http://www.aerorocket.com/AeroCFD/Instructions.html https://www.grc.nasa.gov/www/k-12/InteractProgs/index.htm http://www.qualitysimulations.com/rcs/manual.php

Mate you reinvented the wheel! :megalol: THANKS, IT WORKS!!!

drag coefficient of aircraft when lift equals zero https://en.wikipedia.org/wiki/Parasitic_drag

Thanks! will try it tonight!, indeed my joy was working fine in all previous versions since lock on!, including DCS versions until 1.5.3, in the last one I'm fighting with the stick all time! :wallbash:

Indeed, and your data is ok, and reflects the figures in the missile_data.lua for the AMRAAM (AIM-120C) which are: accel time: 8.0 seconds fuel flow rate in second, kg/sec: 6.43 thrust, newtons: 16715.0, So 2,930 km/h in six seconds at 343.5 meters MSL, is not unrealistic and can reach more (two seconds left of thrust!) Altitude (MSL) 343.5 CAS (Calibrated Airspeed): 2911.581670392374 Mach: 2.401042667360204 TAS (True Airspeed): 2930 EAS (Equivalent Airspeed): 2881.8991739205467

Nothing, I did what you say and the triming is not working.

LOL, dont worry we all know about the F-15/UFO capabilities in DCS! :pilotfly:

Lol, yeah is mach 5.83! read below Altitude (MSL) 13500 meters CAS (Calibrated Airspeed) 2788.649385123618 Mach 5.836665158985399 TAS (True Airspeed) 6200 EAS (Equivalent Airspeed) 1498.2417633620958

I posted the problem, is a bug, the aircraft is always trimming, try to clear the trim with CTRL-T and you will notice that the trim lights keep OFF and should be ON. I have everything OFF, FF, HOTAS at startup, Trim Force 0%, Shake 0%

You have no problem with the trimming in the SU-27 beta? mine is impossible to fly

You're right, the trim lights are out and the FM is not reacting, I pressed CTRL-T to clear the trim and the lights stay off, good point!

I have only one controller, the joystick G940 and the trim is not working in SU-27, I tried with keyboard, with HOTAS, with stick to trim, and nothing ... and I dont have double axis binding, simply is not working FF off HOTAS at startup .. off Trim Force 0% Shake 0% In fact the joys is working ok in everything but trim
