virgo47 Posted March 6 Posted March 6 (edited) Hello fellow Yak-52 friends. Now, when we finally have the Special Options for Aileron and Rudder Trim - how do you set them up? I tuned them around 2 and 19 for some kind of leveled flight close to the cruise parameters, testing it with the Caucasus Free Flight mission. But I'm curious about your opinions! Of course, no Auto Rudder, not sure how that one would affect it - but when it says Auto, I turn it off. (And yes, it took forever to get these trim options, but thanks ED for finally delivering this. No sarcasm meant, better later than not at all.)

Toriy Posted March 7 Posted March 7 For ailerons, IRL, by default, they are set to compensate propeller's effects at 250 km/h, The same, I believe must be for Rudder. In DCS by default they are set for 220 km/h, if I remember properly. But this up to you. If you fly YaK for aerobatic or only to muster your pattern work, or cruise, you may set them accordingly.

To counter the various prop related effects you usually use rudder trim IRL. Bernt Stolle - Art for Sale | Fine Art America Edited May 4 by bbrz i7-7700K 4.2GHz, 16GB, GTX 1070
Toriy Posted May 5 Posted May 5 (edited) Aileron trims are to regulate (sorry, Yandex Translate)"Transverse balancing of the aircraft" (The X-axis). On the Yak-52, according to "Practical aerodynamic of Yak-52 and Yak-55" book (sorry, Yandex Translate again) "The reaction of the propeller rotation can be balanced by deflecting the ailerons (Fig. 139), lowering the right aileron and raising the left one (the control stick is deflected to the left). This is how balance is achieved. On the Yak-52 and Yak-55 aircraft, this moment is compensated by the deviation of the fixed trimmers mounted on the ailerons. These trimmers are small duralumin plates that are attached to the rim of the ailerons. By bending the trimmers to the side opposite to rotation, the aileron deflection is achieved at the design level. mode and load relief on the control stick. As a rule, the calculated mode corresponds to a flight speed of 250 km/h. These trimmers are called compensating, removing the hinge moment." Ruder trim is for (Yandex translate) "Aircraft track balancing" (The Y-axis) I can only assume that this trim is set also for 250 km/h, they do not say this in the book directly Edited May 5 by Toriy 1
