Great! thanks!

what about throttle response?
its take alot of time (8 sec) the engine to develop power
in real life C172 engine develop full power in max 2 secconds

With the 2,400rpm propeller, the static ground rpm is just over 2,100... I find I get to that in around 2-3 seconds from idle to full throttle... It has never taken more than 4 seconds to reach full power on the ground...

Its confused because in A2A model
the static RPM reaches in 2 secoond as real 172 but the engine develop full power in about 8 secconds

It is a fixed pitch propeller... power should be a direct function of rpm. How do you know it takes 8 seconds to reach full power, if you are reaching 2100rpm in around 2 seconds on the ground?

Maybe I have misunderstood something...

That is one of my biggest issues with this (and most addons) without the seat of the pants feel of being uncoordinated in a real aircraft, we have to rely on the turn and bank indicator in flight sim. I know you mentioned fixing that, so am hoping it'll be part of the update! Thanks!
I'm not sure why, but the both the A2A P-47 and B-17 also exhibit the same erroneous behavior as the 172 in regards to turn coordinator physics. Skids are exaggerated the same way in all three aircraft. I wonder if this is somehow related to Accusim? I agree that this makes true coordinated turns almost impossible by referencing the ball as it's currently modeled.

The impending update and the continuing effort to fix the current issues with the new 172 are muchly appreciated by all we A2A customers though!

RPM indicator is only indicator and not like default sircrafts not reflect true aircraft RPM so in this model RPM indication go immidiatly to 2100 but in background true RPM increase slowly to static RPM
I check this by using default gauges and also I have problems making touch and go safely on 900m runway as I used to in real life

Dear A2A-Team!!!

This exactly is what keeps me coming to A2A every time you launch a new product.----> SUPPORT 8) 8) 8)

I would be really grateful if someone else could chime in here, as I really don't understand the issue. How can I see when the engine is providing full power if not by the rpm gauge, when I am using a fixed pitch propeller? If I see the static prop rpm of around 2100 being attained in around 2 seconds, I can assume that the engine is producing its max thrust (I am assuming near sea level and standard air and so on), or am I making a fundamental error?

Thanks

You are correct; all variables equal, with a fixed prop, RPM is your power reference. But the most important variable, is airspeed. You can achieve proportionately high RPM, with a modest throttle setting, in a steep dive (high airspeed)... and conversely, proportionately low RPM at full throttle, in a steep climb (low airspeed).. Let's say, for reference, it's 2400RPM in both cases. Same RPM, different level of power(HP) being generated.

This highlights one of the advantages of a constant-speed prop.. You can keep RPM at or near where the engine generates more HP, regardless the throttle setting, or airspeed.

Cheers Brett, thanks for the insight :)

I should have added "on the ground" to make it 100% clear.

There appears to be some issue, otherwise Scott would never have posted.

Thanks to all... Just did some touch and goes at Shoreham on the English South Coast. As it is, I am certainly getting used to "flying" this one.

Looking forward to the update as well...

On the ground, too :)

When you first go full throttle for a takeoff roll.. the RPMs hit ~2100.. then as you roll, the RPM is "allowed" to increase to where more HP is being generated.. so, whether you sense it or not, you're getting more thrust AS you gain airspeed, but quickly hit a fixed-pitch prop's efficiency "wall"..

Then, as you climb, you "force" the RPM back down into a lower HP spot on the power curve... and then as you level for cruise, the engine is again "allowed" to seek the higher HP, higher RPM.. to the point where you HAVE to reduce throttle for the sake of engine wear.

I believe the issue being adressed, is the time that the A2A engine model uses up, as the RPM/Power/Thrust change, per throttle change.. IOW, the lag..
