RE: RealFlight G4.5 oddities
Eh, you're imagining it.
Seriously... Trainers are BUILT to climb when power is applied.
The included trainers however bleed off airspeed too fast when throttle is cut and don't maintain long glideslopes.
If you want a "spot on" trainer for the sim that behaves EXACTLY like the real thing, head over to the KnifeEdge Swap Pages and grab the freebee Alpha 40 Trainer.
You will not find a more accurate trainer model anywhere!
