no excuse really, su25 is the best to start on and slowly move to tf with clickable cockpit and more control needed. Yak is not easy, handling is too fast for noobs, not seeing the runway ahead is a no/no, L39 will crash them asap :)) as a begginer you want a plane with slow rate ailerons, steady flight, steady power, autopilot, predictable behaviour, easy to use cockpit, airbrakes and/or parachute, great visibility over the nose ! yet again one gamer that only touched war thunder & other arcade needs first serious time in civilian sims like fsx/p3d/xplane
