July 13, 200520 yr Hi Guys,Ive searched the forums for answers but found nothing.What i want to know is how one steers GA planes while on the grnd.I have a set of CH Pro pedals which i converted from gameport to USB.I use Leos MiniMe.What i am finding when trying to take off is how to keep the plane on the center line.I find that when the plane veers to the right and i apply a certain amount of correction there seems to be a delay.Consequently when the correction occurs its to much and i look like a drunk on a Friday night.If i look at the rudder while on the ground.any rudder pedal action is directly seen in movement of the rudder.So there is no delay here.I calibrated the pedals in FSUIPC.Is what im experiencing normal for light aircraft(i fly the DreamfleetC177RG).I find if i fly the heavies,im able to control direction muchbetter.Iv played around with sensitivity but this doesnt help.Its more of a delay but only when on the grnd.Any comments would be much appreciated.Rgdsles

July 15, 200520 yr Many years ago, when I was a beginning student pilot, one of the hardest things initially for me was simply taxing the plane (150's and 152's). I'm sure I did look like a drunk on a Friday night. Fortunately I flew better than I taxied. My instructor told me to stick with it, not overthink it, and one day it will just happen. And one day it did - all of a sudden, not some gradual improvement. Most light planes control the nosewheel through the rudder pedals. Some twins use other methods. (Is it the Aerostar that literally has a rocker swith for control?) Nosewheel steering on a heavy is different in that most, if not all, use a "tiller" on the cockpit side wall for low speed taxing (sharper turns). The rudder pedals only have limited (smaller) nosewheel control authority so you don't drive the thing into the weeds during takeoff and landing. Now, its been a long time since I've flow a real plane, and I've certainly never commanded a heavy. But it's my impression that light planes are more sensitive on rudder steering in general. Sensitive once you get them turning that is. One issue with light planes is nosewheel shimmy, and often this is combatted design wise with dampeners in the steering system. Which is great except that it produces a bit of a lag in the actual nosewheel movement vs your rudder pedal inputs. This is different from sensitivity - how much the nosewheel moves for a given amount of rudder pedal travel. The nosewheel eventually gets there, but it takes it a second, which can cause a tendancy to overcontrol. I think what clicked for me those years ago was to slowly apply steering (easing into the turn) and that I finally gained a feel for how much deflection was required to turn at a certain rate. As my instructor said - small corrections early (and this applies to all phases of flight). Now, after that discussion (sorry to be long winded), I do think that steering is one area where our sims / sim hardware are not always 100% realistic. I suspect that the sensitivity / null settings for the rudder are played with far more often than the other controls. But this is of course all my opinion. Perhaps some other folks with more recent experience in a real 177 and or the Dreamfleet 177 (neither of which I've flown) will comment some more.
July 16, 200520 yr The C-177 is basically a souped up C-172 with a missing strut. I don't know if it uses the C-172 or C-182 nose gear but, I bet they act the same. The C-182 is "slightly" heavier in the nose steering because, of the heavier engine. I am familiar with what he is talking about in sim nose wheel steering.

July 16, 200520 yr My two cents:1. Make sure the movement range is *big enough* - so that you can move your feet without being super-sensitive and accurate. 2. Make sure there's enough *resistance* in the pedals. I have tried CH pedals once. They were just WAY too light.These two things combined make it easier to use the pedals. So that full deflection of the rudded does require quite a lot of force (think "car clutch pedal" - it has a strong return spring for a reason.. imagine if it was very light.. would be very hard to drive smoothly..)And the other half of the thing is that the movement needs to be long enough to make it less precision work.I have adjusted the FSUIPC response curve for our pedals - I dont use "null zone" but FSUIPC has a slightly flattened centering position. They are still a bit rough, but I have just decided to not care much. I am more interested in the flying part than the taxiing :)And well, steering a real Cessna with pedals is not like turning your car's steering wheel - it's more rough, and takes some getting used to. It's also harder because you dont feel the movement on your butt, but rather you need to rely on the visual cues of the scenery - making it even harder - our sense of motion helps in real life. //T
July 17, 200520 yr Author Thanks Guys for your commentsGot the feeling that is was just a Fs thing.Have tinkered withsensitivity and other things but could not seem to get what i would have expected.Not really bugging me,more curious.Must say since i threw out the 100k log pot that Ch fits and replace it with a linear one and recaled in FSUIPC things are better.Les
