trim

Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force. This is done by adjusting the angle of the tab relative to the larger surface.
Changing the setting of a trim tab adjusts the neutral or resting position of a control surface (such as an elevator or rudder). As the desired position of a control surface changes (corresponding mainly to different speeds), an adjustable trim tab will allow the operator to reduce the manual force required to maintain that position—to zero, if desired. Thus the trim tab acts as a servo tab. Because the center of pressure of the trim tab is farther away from the axis of rotation of the control surface than the center of pressure of the control surface, the moment generated by the tab can match the moment generated by the control surface. The position of the control surface on its axis will change until the torques from the control surface and the trim surface balance each other.

    MG5 PFL Chrome Delete

    I came across this video: They use black vinyl wrap to cover up all the chrome trim, apart from the front badge. I'm not really one for cosmetic mods but I have to say it looks rather better than the original. I don't own an MG5 but if I did I would be rather tempted to do it to the front end.

    New car day

    Picked up my Face Lift SE today, waiting for the old SR Excite to get collected. The SE seems a much improved car, love the trim inside and infotainment system. Sure I’ll have a few questions over the coming days

    Wheel arch trim - Replacement?

    Hello, I scratched my wheel arch trim on the front right side of our MG ZS EV (FL). The part is 20£. Does anyone have experience with the replacement? It is difficult? What tools are needed (I saw a few clips)? Bye.

    Decorative Skin

    I've noticed the decorative skin/film over the shiny black parts of the steering wheel are bubbling; and in one area the edge of the trim is breaking up. Before I make a complete idiot of myself, can anyone confirm that this 'film' is or isn't permanent, and could be peeled off, like, say, the...

    2023 MG5 trophy. I've got a strange rattle, seems to be coming from inside the boot lid. Anyone any ideas ? Sounds a bit like loose trim inside the boot lid. Driving me crazy when driving.

  8. MG 3 Hybrid Essence Trim

    I just thought I'd show you the entry-level model available here in Ireland. Basically, there are three trim levels, Essence, Excite, and Exclusive. The Excite is the same as the SE in the UK and the Exclusive is the same as the Throphy. The Essence is still reasonably well equipped but misses...

    Archived MG4

    Hello folks, I'm looking for an MG4. Red or white preferred but any colour considered for the right price. My budget is £15k so an SE that's a year or two old would be fine. My location is Birmingham. Thanks

    Wheel trim top coat peeling off.

    Has anyone experienced the clear top coat peeling away from the surface of the wheel trims on ZS ev. I'm very disappointed that MG has declined this as a warranty claim on a two year old car.

    (Carplan) Back to black trim shine

    Something which for obsessives like me that has proved to be very useful, is black trim shine product. This is in effect a black paste that you wipe on and buff off. Like a lot or cars particularly in the supermini sector the MG3's cabin is an abundance of what is usually described as scratchy...

    Wheel trim theft?

    One of my MG4 wheel trims 'disappeared' in a garden centre car park whilst we were inside, I had not kerbed my car or collided with anything. I looked to ebay for a new one but those there were all used. Are some people pinching wheel trims only to sell them back on ebay and get a 'good ebayer'...

    MG5 pre-FL - removing the tailgate trim.

    Hi all, I've just had to contend with the tailgate trim (the interior plastic panel) on my car to replace the number plate bulb on a pre-FL MG5 LR. The manual was pretty useless on this, so I've put together a quick guide to removing the tailgate panel (I couldn't find a good one elsewhere...

    Front radar on FL

    I had some kind person reverse into the front of FL and drive off. I heard the noise but did not get out in time to catch them. The car looks fine but I noticed the black plastic trim around the front radar was pushed out of place. I have managed to slot it back to where I think it should...

    Seat trim "stitching" colour..

    Call me dozy, but I've just realised our red Luxury (equiv. UK Trophy) has a blue "stitches" effect on the seats. Shouldn't it match the paint colour, or has anyone else got this kind of mismatch?
