[CTD] when requestting some Sim Variables with SimConnect and helicopters

When an helicopter is selected as an aircraft, if you request one of the
variables “ELEVATOR TRIM DOWN LIMIT", “ELEVATOR TRIM NEUTRAL” or "ELEVATOR
TRIM UP LIMIT” then the app freezes then crashes. To reproduce the problem,
you can:

  1. Start MSFS,
  2. Select any helicopter and any airport
  3. Start the flight,
  4. Start the SimvarWatcher SDK sample,
  5. Add a request for one or more of the 3 variables with default unit (radians),
  6. Connect to the simulator,
  7. MSFS freezes then crashes.

Hello @Boups , Thank you for reporting this bug and for pointing out the
reproduction steps, A fix is in the making, Regards, Boris
