Manual Trim Control

[SWrokit]

Pros & Cons?

Trying to find some information regarding trim control.  What it does, why it does, if indeed there is any benefit at all in using trim (other than auto).

Have been looking at new joysticks (still undecided on that one lol) and was reading about one that has duel throttles, which doesn't much impress me since I use the CH throttle.  However, in the description narrative it stated the throttle could also be used as trim control.  WTF!!  I have a throttle now that I don't use on my current stick, never gave it a thought.  I also have an unused mini joystick on my CH throttle I don't use.

I guess the point of my post is I'm looking for input regarding trim control.  Reference to any reading materials, and how to set up my controls for it.  (That is....if it's even worth doing  )

Thanks for the advice.

You will find a quite extensive article about manual & combat trim on the Aces High Trainer Corps webpage (under "learning to fly")

Rokit, depends on the plane as to where manual trim will benefit.  Some really love it.  Go off line and do some hi speed dives using manual trim with your E6B open.  Try it with several planes.  You'll soon see some amazing things.

Many a dive in a compressed 109 has been saved from "face planting" by hammering on the the Elevator ManTrim key "K" - better still if you can map it to a wheel/throttle. As stated it depends on the dive compression aspects of the individual plane.

well worth the investigation for that single point alone.

...cheers eh!

I've got aileron and elevator trim mapped to one of the 4-way hats (the "rook") on my CH throttle.  I rarely use rudder trim, so just use the keyboard if I feel the need for it.  I've noticed that combat trim doesn't always compensate for certain situations, like very high or very low speeds, WEP, asymmetrical external stores (dropping left wing bomb/tank but right wing bomb/tank still attached), etc.  I use manual trim in those situations to negate the slight roll away from level flight.  I also use manual trim during landings or any other time I want to deploy the flaps.

Lusche definitely a good read Bro, thanks.

I can already see the benefits of having trim buttons at your disposal.  Everything from diving to turn fighting.  I can also see where these functions would be of help with "Stall Limiter" disabled (FINALLY).  So far from what I've read, the "Trim Up" function is what needs to be programmed in, and that "Auto Trim" cancells it out when engaged.

Been playing AH for 7-8 years, AW before that.  Time to take the training wheels off  .  I'll get this setup this weekend and hit the TA...................

Hadn't even given that a thought.  But your right, especially when your carrying 1000 lbers.  Drop one and you begin to roll towards heavy side.  I've always compensated with joystick.  And I do have an empty 4 way on my throttle..........thanks.

Thank's Gents for the assist & help.

Down trim is handy too for those planes that like to nose up in a higher speed dive like the Spits, Bostons, etc.

One thing to remember is do not buy into the AH urban myth that using manual trim will somehow make your plane turn tighter.

CC on that Ack.  I know disabling the "Stall Limiter" will enhance the turn ratio a little, and my thought (based on absolutely nothing lol) is ........when in a tight turn, and little up trim may assist in preventing stall out.  Again this is based on nothing.  Everytime I've disabled stall limit I've totally crashed and burned

Just my humble opinion but you need too learn to fly to the edge and a little beyond without the stall limiter before you start worrying about manual trim.

Don't think there's anyone here who can't say the same thing there Rokit.  You just have to stick with it for a few weeks to get used to it.  Took me at least 2 tries to finally force myself to keep the stall limiter off.   Saw a big difference after that, my only regret is that i didn't do it sooner.

yes it does.

and the 38L has dive brakes.

rokit.....


turn off the stall limiter, and fly that way in fights for a little bit. you'll learn to love it. you'll find yourself riding the buzzer more often, and also learning to keep her from stalling to begin with. when she does stall, the recovery can be tricky, but it will enhance your fun, and fighting too.

People who scale their sticks and trim up for turns are in effect moving the "more scaled" area of stick movement to a higher AOA. This makes it easier to stay at max AOA without going too far and losing lift. So trimming up makes tight turns easier. It won't make the perfect turn any tighter, but it could help make a good turn better.
