shanwick Posted December 6, 2014 Share Posted December 6, 2014 In one aircraft that I fly I need to turn the yoke quite a bit to left or right to initiate a turn whilst in another only a very small turn of the yoke is required to get exactly the same rate of turn of the aircraft. Does anyone know what parameter I need to look at to change this or is it more deeply buried in the overall dynamics of an aircraft? Many thanks for any ideas.

n55 Posted December 6, 2014 Share Posted December 6, 2014 Sounds like a null setting that is different from one plane to the other. If you have FSUIPC installed (pay version) you can re-adjust your ailerons and rudder for each individual aircraft. Link to comment Share on other sites More sharing options...
Avechelice Posted December 6, 2014 Share Posted December 6, 2014 Hello, You can also check this section in aircraft.cfg [flight_tuning] elevator_effectiveness = 1 aileron_effectiveness = 1 rudder_effectiveness = 1 elevator_trim_effectiveness = 1 Compare with other aircrafts ... change values ... test ....

jgf Posted December 7, 2014 Share Posted December 7, 2014 Yes, the effectiveness parameters in the aircraft.cfg are the first things to check. The values can be related to percentage, "1" = 100%, so 0.95 would be 95%, 1.10 would equal 110%. Arguably there is no "correct" value here, you're basically balancing the designed aircraft values to your controller. Link to comment Share on other sites More sharing options...
shanwick Posted December 7, 2014 Author Share Posted December 7, 2014 Thanks for the replies and suggestions. I had already tried these but without any luck. I can live with the "problem" though, it's just that I was more curious than anything else. Ta!! Dijvid Link to comment Share on other sites More sharing options...
gwillmot Posted December 7, 2014 Share Posted December 7, 2014 I can live with the "problem" though, it's just that I was more curious than anything else. Ta!! Dijvid Actually, it's not a problem at all. In fact, it's more realistic. Would you expect a B777 to have the same turn characteristics as a Pitts S-2C? Of course not. But .... you might be talking about the same aircraft model from two different sources .... in which case ..... it could be considered a "problem" in one and possible both of said aircraft. Not knowing which type of aircraft you are talking about ..... one can only speculate at this time. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
mikeandpatty Posted December 7, 2014 Share Posted December 7, 2014 I think you mean "rate of roll" vice rate of turn. Rate of turn (degrees per second heading change) is a function of bank angle and true airspeed. Aircraft type does not matter. Rate of roll is change of bank angle per second - a function of aircraft design determined by aileron effectiveness, roll stability and roll inertia among other things.

Ya ..... what you said .... except I don't agree that rate of turn = aircraft type does not matter. You ever hear of momentum ...... which includes something called "mass"? ..... so F-22 has same rate of turn as B-1 at same bank angle and true airspeed? .... back in your court ..... BTW ..... NOT talking about Standard Rate of Turn [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
Avechelice Posted December 7, 2014 Share Posted December 7, 2014 BTW ..... NOT talking about Standard Rate of Turn Wing load :) BTW for aileron effectiveness... aileron_effectiveness = 1 Put 0 as value and check what will happens :) If you gave a couple of monkeys a box of ballpoints, enough paper, and enough time, they'd eventually finish up writing the complete works of Shakespeare :) Link to comment Share on other sites More sharing options...
shanwick Posted December 7, 2014 Author Share Posted December 7, 2014 This thread has gone off-beam somewhat. Of course I know that the rate of roll or turn or whatever it is you wish to call it - let's not split hairs on it - is not going to be the same for all aircraft. What I was asking is why I have to yank my yoke a lot to the left to achieve a turn in one aircraft but just tweak it a little in another aircraft.

tiger1962 Posted December 8, 2014 Share Posted December 8, 2014 So, both single engine light aircraft, one high-wing and one low wing - should be about the same yoke response in sim (if not in real life). I presume you're investigating your sticky yoke issue from your other thread? If so you might want to order something like this: http://catalog.antiseize.com/item/lubricants-penetrants2/ptfe-spray-light-coat-dry-lubricant-and-release-ag/17075-1 I've never tried it but someone Stateside may be able to comment. Just to eliminate that issue, we could also test these two on our sims - which C172 & PA28 are they? Tim Wright "The older I get, the better I was..."

napamule2 Posted December 10, 2014 Share Posted December 10, 2014 Tell me whose models you are talking about and I can fix it where the prop WON'T turn at all and the jet will spin-on-a-dime. And please indicate if the models you are talking about have the problem both when in the air and on the ground-in case there is a difference due to contact points as opposed to flight dynamics.
