RELEASE: MilViz Corsair for MSFS

@Kapustick

your recommendation to zero the aileron trim on takeoff is valid

That was me, not him. You’re welcome! (also with some pointers to it being the cause by @FlyingsCool5650 )

@Sonicviz

If you reset your rudder/aileron trims after take off (say 300’ or so) you will find it should fly level. It’s only logical it’s going to spin to the right after take off if you take your hand off the stick with right rudder/aileron trim still applied. In real life you would roll them off progressively to a stable light stick stable position consistent with the flight phase, which is easy if you have key binds or control binds, not so easy with a mouse.

Aileron trim has always been a part of this plane, mentioned in the take off checklists as a key setting, and the torque has always been minimal in flight mode. Whether you apply that or not is up to you, but it’s basic flight knowledge to understand what effects trim settings will have on an aircraft in all phases of flight. Feeling the plane roll to the right if you lessen the stick pressure after take off should be a clue that the trim is now overcompensating, so you can roll it off. Physics! This is transferable learning, as it’s a general principle that can be applied to any plane and trim settings in different flight configurations.

If anything, the only thing that needs changing is the manual should mention rolling off the rudder/aileron trims to zero (or whatever setting needed to level it out depending on torque effect) in the after takeoff checklist. (suggestion for @Krazycolin ). It does mention trims in the after take off checklist, but only refers to elevator trims, and it should really give a shout out to the rest of the trim family seeing as they’re set in the take off checklist. This part applies to all warbirds with these powerful torque enignes, and you may be better off rolling it off in the case of other warbirds that have different flight model torque effects modelled.

eg: Here is how one user of the new FI BF109 views them:

@StormWinter7

To give you an idea of difficulty to take off/land for the 109 I will rank it with the other FI birds and the Milviz Corsair, the first on the list being the most easy.

1 - P38

2 - F6F

3 - Spitfire

4 - Corsair

5 - Bf 109

Adjusting the Torque to be stronger in flight phase is possible, but I guess you could always mod that too if you really feel the need for it.

The learning points from this discussion I would see as:

• How .flt flight files work, what they change, and why
• Aircraft checklists are there for a reason
• How aircraft torque and trims work in different flight phases.
• Models are not reality. Which is fine, these are only rough approximations of reality. Go with it!

Also, as previously mentioned,

@Sonicviz

It’s aileron trim that is doing the bulk of this stick off right roll, more so than the rudder trim, so if you feel you can take off ok without aileron trim that’s one less thing to worry about. I tried it, you can, but a bit of right aileron trim “feels” better to me. I quite like the stick control game on takeoff with 6/6 settings on R/A trim, so I’m ok with that. YMMV.
