Milviz Cessna C310R Thrust Issue

Good afternoon!

I looked for for a long time along the official C310R thread, but i did’n find anything talking about that.
I have a little strange issue with this aircraft, that I don’t know how to solve…

I’m using Flight Simulator on Xbox Series with the Xbox Controller (by the moment), and since a few days ago, this beautiful Milviz C310R offered me a limited thrust… It´s like if it offered 70% of its power. It`s nothing about the aircraft configuration, it must be something from the command controls, or that the aircraft detects the speed brakes on (that’s not the problem, because this reduced power it’s also on ground…), or something like that… I have not changed anything. I follow the same procedure that I always follow to fly.

Does anyone have any idea how can I fix this??

And; If I delete the aircraft and reinstall it, do you know if the data like the flight hours of the aircraft counter are deleted?

Thank you so much in advance!

You may have fouled the engine with the wrong mixture and engine settings. When I had those symptoms that was the problem.

From the manual,
"General Notes about operations with authentic engine simulation:

  1. When on the ground, especially when taxiing, you should lean out the
    engine. Not doing so will tend to damage the spark plugs over time due
    to fouling.
  2. Except for a short time after takeoff where full power is required, you
    should avoid running the manifold pressure and RPM outside the green
    arcs. Doing so will damage the engine over time. Most 310R procedures
    call for power reduction at 500 to 1000 feet AGL to the top of the green
    arcs, which is the “cruise-climb” setting"

I’ve fixed it before by running the engine at high power on the ground, with brakes set, for a few minutes to burn off the fouling

Also check mags and ensure that you’re leaned for density altitude. Density altitude itself will cause a loss of manifold pressure and resultant thrust/power no matter how well you lean.

How did you ascertain that you have 70% thrust? Is that the throttle position read from the HUD or is that a guess based on performance? Again, I question back to the potential density altitude issue.

Lastly, it could be a strange keybinding that’s killing a mag or causing micro drops in one or more of the axes that affect power, to quick to see visually, but you end up losing the average of the difference.
