My Impression Of the Flanker

[Chappie]

Congratulations ED and thank you for more attention to the Flanker. I do enjoy it but notice a few things I do not like.

 

For one, when I am at a runway approach speed of 280 kms/h, the aircraft is inducing pilot induced longitudinal instability that yields large roll input on small corrections. This is entirely caused by the automatic application of rudder which further exacerbates the situation. I note this primarily because I am used to relying on small roll corrections without the use of rudder to correct lineup. At 280 kms/h and below, the aircraft is already entering minimum controllable airspeed and a slow approach speed ensures no bounce and soft touch.

 

Secondly, the aircraft requires the use of trim almost as if that is my primary flight control than pitching the aircraft with the stick. This tends to present an aggravated acceleration after takeoff that can even result in pilot induced oscillation about the lateral axis. Also, the aircraft flies as if it is on a cushion of air ... floating if you will. I actually feel as though I should set my Y-axis to the trim rather than the elevator. Given the aircraft's nose heavy tendency beyond 10 degrees causing the aircraft to flip onto its' back, it becomes very tricky to fly it even without disabling the limiter.

 

Third, I appreciate penalties for rough handling the aircraft but tires popping upon full application of the brakes (W key) after 4 seconds is a bit unreal. This happens all the time and nearly under any condition. It also always seems to be the left tire. I am seriously thinking: if(w key pressed more than 4 seconds){pop left tire immediately}. There is no randomness like var popTire = Math.random() if(popTire < 05){call popLeft()} else {call popRight()}

 

Fourth, thank you for modelling the high maneuverability of the Su-27. It has been a pleasure to test it out. Problem I see is the propensity of the aircraft to flip onto its' back and there is a high propensity to nose down at slower speeds. I want to take what I see in Youtube videos and match it to the Flanker ... I do not feel the Flanker is there yet.

 

Fifth, did the aircraft engine power get boosted? Taxiing for me involves setting power to 80, watch a fast acceleration to 50 kms/h in under 3 seconds followed by knee-jerk reaction of power reduction, braking, that popped left tire again, and having to restart my flight. Compared to the present Su-33, the Su-27 feels like it is on steroids and even in flight I notice with power above 80, it won't decelerate until lowered below. Starting to feel like if(n1 RPM >= 80) {increase acceleration fast} else{slow plane through braking}. Yeah under 80 plane decelerates much faster than it should without brake application as if if(power lower than 80){brake aircraft to 0 kms/h through??? magic??}. I noticed the Su-25T was throttle neutral and still rolling at like 0.5 kms/h. But the Su-27 is braking like it has autobrakes. Things have changed quite a bit from the original aircraft.

 

Sixth, again, thank you for the Beta Su-27 and I do hope you plan to continue and improve the flight dynamics. Thank you for the Su-27 since Su-27 Flanker was a product and I look forward to variants like the Su-34.

Your 5th point had me chuckle. I know what you mean on that one. Any thing under 80% you say "why the hell are you not moving?!?" At 80% and higher your screaming at the top of your lungs "STOP" and praying that you don't die rolling down the taxi way at the speed of light lol. Good times.

 

In all serious though I just power up to 80% let it go to 50 to 70 in the hud then cut the throttle back to 75% and roll around. It's fun.

Read about taxiing here if you didn't already.
