Piper PA28RT Arrow IV Flight Model Issues

Recommended Posts

I purchased the PA28RT Arrow IV via the STEAM DLC.  The Vr speed for rotate according to the  A/C manual is 65 - 70 knots (depending on weight and conditions)  I just did a take off roll and I couldn't get off the ground until I was at 110 knots.  I have flown this A/C and know that can't be the case.

 

Am I missing something?

 

Thanks!

Check your elevator trim settings.

Thanks Greg,

 

I tried different Trim settings and still I need 85-90 knots or more to get the A/C off the ground.  I really think something is wrong with the model.

 

Thanks!

Hi...

 

I haven't used their Arrow since FS9 - it's one of their older works and had abysmal flight dynamics in FS9 - never tried it in any of the newer sims...

 

Regards,
Scott

Skyseek,

 

I have to agree with Scott. That was an earlier work for Carenado and the flight dynamics were horrid at best. Here's a fix for it though. Go to your aircraft.cfg. Scroll down to your "flight tuning" section. Change two values.

elevator_effectiveness=2.2

pitch_stability=1.75

 

Those two values will certain make it flyable. I have no idea for the life of me why they made the elevator basically ineffective in this plane with such a low value of 0.7. Also adding some elevator to it means you're going to have to make it a bit more stable otherwise the nose will pitch up and down on you. Give those a shot and let me know how it works out for you.

Oh wow I remember that model... great looks, horrible everything else.  Since then they've gotten better for sure.  Especially when Bernt Stolle did the flight dynamics.  He doesn't do them anymore...

 Ryan,

I didn't realize he wasn't doing their FDEs anymore.  That really is a bummer.

recently read an article re: the real Piper arrow.Pilots going from the Cherokee to the Arrow (with its stabilator) noticed they had to hold back more on the roll out and and it unpredictably leaped off the runway. forcing a fast trim/yoke correcting for smooth initial ascent.. Sorry forgot the airspeed.
