Why In The World Would A Builder Put Flaps On Trim?

30.3k ChiChiWerx  6.1 years ago

I’ve noticed that many builders put their flap controls on trim control. But...why?!? Often, flaps do nothing for trim control, so you still need to trim. But if you build this way, trim is simply not available and you need constant back or forward pressure to keep the nose level. Also, it’s simply unrealistic...if you’re clipping along at anything more than 250 mph and you lower your flaps in RL, you might rip them right off the wing. The fix for all of this is VTOL...easily accessible and fixes all of these issues. This whole build style is also related to a common misunderstanding of trim...why do so many SP builders dislike trim??? In RL, flying an aircraft involves constantly trimming as you vary your airspeed...so why the passive opposition to the idea of trimming in SP?

    On the planes I've used flaps on, I've normally used something else on the VTOL control

    With eight activation groups, there's no excuse for not having trim.

    The miss-understanding about the differences between Trim and Flaps is another story,
    .
    Actually, we get the feeling, those controls, are depends with how designers or engineers out there planned and select which buttons or sliders are suitable for which controls on the aircraft,
    .
    some people prefer to use multiple AGs with only one slider for multiple controls. some other people prefer to use those two sliders with multi AGs for even more controls,
    .
    It is about how each people decide the best controls for their planes in SP,
    .
    Trim Slider and the Trim control on a plane has nothing to do. Okay, they do, by default, but we can change that,
    .
    Okay, a Trim control on a plane that was set with Trim Slider input, so it is a Trim... if a Trim Control on a plane that was set to VTOL Slider Input, so what do you want to call it? A flaps? Lmao. it is still Trim,

    I have to disagree with you on this. Sometimes it actually makes a lot of sense to use trim instead of VTOL for things like flaps. For instance, flaps placed on a conventional aircraft (if done right) actually force the nose of the aircraft downward as extra lift is being generated further back than it would normally. To compensate for this, you need an elevator input to to counter the downward pitch. However, by assigning flaps to trim, you can reduce the downward pitching motion proportional to flap position and free up the VTOL controls for something else important.
    .
    It's a very efficient way of killing two birds with one stone.
    .
    If you're having to fight the pitching up of an aircraft, then you've either exceeded the intended cruise speed (which believe it or not isn't 100% throttle all the time) or the aircraft is badly designed.
    .
    I'm not sure what your point about deploying flaps at speed is, you can still deploy them anytime using another input method and the same can be said about the landing gear. VTOL input doesn't magically stop you from deploying flaps at Mach 2.
    .
    In conclusion, it's a game. If people want to use trim for flaps, that's their decision. It's their build and they can do what they like with it.

    Because it’s easy to recenter them.

    @ChiChiWerx I'm glad someone else thinks this, I keep getting comments about trim not being set right yet have provided a trim option (for elevator). I'm no expert but I'm assuming trim will change depending on speed, fuel and general loading?

    Because they're lazy and using control surfaces for flaps

    Because sometimes the vtol is already used and it wouldn't be realistic to put it on vtol either right? Anyways trim just feels right to put it on.

    Some people just prefer trim. They might need to dedicate the VTOL slider to another function.

    And another question : why do I think I totally agree with you ? 🤔
