" 3) Pfalz D.IIIa - maneuvers too good, horizontal speed too low "
Good to hear about planned fix for Pfalz DIIIa unrealistic manouvers in ROF but i wonder what with some other German planes like Albatros and Fokker DVII?
I post about these in other topic but i think Neoqb should check these things also.
I made 3 short videos with Se5A, Albatros DVa and DVII when i test how they react in sharp turn and pull up with maximum deflection of stick.
First video is how plane with good FM should stall in hard turn. Se5a stall immidietly in such turn when reach critical angle of attack.http://www.youtube.com/watch?v=88PoK6Q05ck
Second and Third video is with German planes Albatros Dva and Fokker DVII. They dont have accelerate stall at all and could do some unrealistic manouvers. Look how they make loop - Fokker DVII could make a loop at maxium deflection of stick at high speed near in a spot ( burn all energy in such manouvers but has not accelerated stall and make manouvers near in a spot)
Here are pilots notes about these planes :
"To get a better feel for what this airplane can do, steep turns, lazy eights and wingovers are attempted, all easily carried out but an excessive amount of adverse yaw is experienced.
The adverse yaw is easily compensated for, by balancing aileron application with rudder and doesn’t prove to be a problem at all. Next, slow flight and stalls are explored, a good idea to check before landing.... again nothing unusual other than the fact that this airplane is rather easy to fly. Adjusting the elevator trim allows the SE5a to be flown hands off something I’m not used to in a WW1 fighter. A few more stalls are investigated and a power off stall speed of 43 mph is noted.
With the power pushed up a bit, a conservative top speed of 115- 120 mph is achieved!
I would expect during wartime even this top speed would be increased to the reported numbers of about 138 MPH. The only aircraft that could come close was the Fokker DVII, so the SE5a was faster than anything out there and very competitive with the later produced DVII. The performance doesn’t seem to diminish with altitude either, it can maintain 120 mph right up to about 15,000 ft. After the formalities of recording figures for temperatures, pressures and airspeeds, it’s time to really get a feel for the new plane. I am still amazed that it is so easy to fly and feels so stable. Turns in either direction are simple as long as they are coordinated with the rudder."
"At the time the SE5a entered service, pilots were arriving at the Front with fewer than 20 hours of flying time, so a plane that could be flown by pilots of limited flying experience was very well accepted. There were far fewer accidents than those experienced with many of the Sopwith or Nieuport designs. While the highly maneuverable designs were better suited to skilled pilots with many hours of flight time, the SE.5a design was entirely different. Easy to fly, stable and forgiving, even a mediocre pilot could capitalize on the steadiness of the aircraft, firing at the enemy from further away with a greater degree of accuracy."
Se5A had lower take off weight and bigger wing area then German Scouts or DVII so it had lower wingloading. It had less camber airfoil then Albatros or Pfalz DIIIa so i expect it has little lower CLmax but other hand it had more gentle stall above critical angle of attack then German Scouts. These really prety good is confirmed by German pilots opinion about German Scouts:
" Apart from its structural deficiencies, the D.III was considered pleasant and easy to fly, if somewhat heavy on the controls. The sesquiplane arrangement offered improved climb, maneuverability, and downward visibility compared to the preceding D.II. Like most contemporary aircraft, the D.III was prone to spinning, but recovery was straightforward."
"German pilots variously criticized the Pfalz’s heavy controls, low speed, lack of power, or low rate of climb compared to the Albatros. The D.III slipped in turns, leading to crashes when unwary pilots turned at very low altitudes. Moreover, the Pfalz stalled sharply and spun readily. Recovery from the resulting flat spin was difficult, though some pilots took advantage of this trait to descend quickly or evade enemy aircraft"

And i think Neoqb did pretty good job with FM of SE5a ( besides these stupid elevator issue and absence of elevator trimm) - these planes fly very natural, have accelerated stall but is quite easy to fly and stall warning is very good.
I cant say the same about German Scouts and Fokkers by Neoqb. They dont behave like combat planes but rather like RC models.
I hope Neoqb will check these things carefully and make all German planes to fly more like RL combat planes not flying kites.
I think the same like Pflaz DIIIa it should be checked and fixed in the same way.
