Pocket Sized Posted May 26, 2016 Posted May 26, 2016 If you go full power and fly straight at sea level (no external stores): A-10A/C: Nothing F-15C: Nothing Mig-21: Engine stalls at 1300kmh Su-25: Mach tuck = uncontrollable dive if not watched carefully Su-27/33: Massive loss of control authority (IIRC) Mig-15: Massive loss of control authority, wing flex causes banking, nose comes up even with full forward trim Mig-29: Haven't tested F-86: Don't own M-2000C: Don't own So yeah. Anyone have insight on this? (I know I'm straying dangerously close to the "P" word) DCS modules are built up to a spec, not down to a schedule. In order to utilize a system to your advantage, you must know how it works.
Vedexent Posted May 26, 2016 Posted May 26, 2016 Su-25 will definitely "mach tuck" if you're not careful. I'm not sure it's a fair comparison to say that its counterpart - the A-10C - is more stable (I know you're not actually saying this), since the A-10C flies a lot slower. I suspect that the Su-25 handles better @ 900Kph than the A-10C does :D

Exorcet Posted May 26, 2016 Posted May 26, 2016 Added response in bold to quote If you go full power and fly straight at sea level (no external stores): A-10A/C: Nothing can't go fast enough unless you dive, breaking of wings becomes easy. I'm not sure I've experienced comprehensibility issues, but again, very slow F-15C: Nothing Rudder madness (low alt) Mig-21: Engine stalls at 1300kmh Su-25: Mach tuck = uncontrollable dive if not watched carefully Su-27/33: Massive loss of control authority (IIRC) Mig-15: Massive loss of control authority, wing flex causes banking, nose comes up even with full forward trim Mig-29: Haven't tested F-86: Don't own loss of roll authority, it would have the same issues as MiG-15, but it has an all moving horizontal tail M-2000C: Don't own So yeah.

Pocket Sized Posted May 26, 2016 Author Posted May 26, 2016 Rudder madness? That sounds like something I could get into. DCS modules are built up to a spec, not down to a schedule. In order to utilize a system to your advantage, you must know how it works.
DarkFire Posted May 31, 2016 Posted May 31, 2016 If you go full power and fly straight at sea level (no external stores): Su-27/33: Massive loss of control authority (IIRC) When you say loss of control authority, what exactly do you mean? You will (technically) overspeed the Flanker going full AB at sea level, but I've not noticed a lack of control authority except for the hydraulic force limit of the control surface actuators. Is that what you mean?

bolek Posted May 31, 2016 Posted May 31, 2016 Also, Su-27 at max speed at sea level will experience autopilot wobbling similar to the effect when the speed is too low.
DarkFire Posted June 3, 2016 Posted June 3, 2016 Also, Su-27 at max speed at sea level will experience autopilot wobbling similar to the effect when the speed is too low. Yep, at anything over ~1,450 Km/h IAS.

gospadin Posted June 4, 2016 Posted June 4, 2016 F-15 has huge problems clean at low altitude if you don't limit your airspeed. You can't get there with wing tanks due to drag, but you can with just 2 missiles or so.

Hadwell Posted June 4, 2016 Posted June 4, 2016 (edited) mig-29 can overspeed, you can get it to 1600+ kph ias on the deck, go far, fast, but run out of fuel in no time, fully controllable throughout, it just stops accelerating once you hit top speed, in a dive you can go faster for a few seconds, till you hit the ground, still won't lose control at any point. 1JZlV_1c7tU Edited June 4, 2016 by Hadwell My youtube channel Remember: the fun is in the fight, not the kill, so say NO! to the AIM-120.
