Akalide Posted June 20, 2021 Posted June 20, 2021 Hi, Stating cold and dark in the Jagdflieger campaign (4th or 5th mission, a bombing mission on britain), taxiing is impossible as the tailwheel remains stuck in rightmost position (I mean facing right). By applying power the plane can spin to the left but no way to get out of this situation. The tailwheel lock lever has no effect, and neither does differential braking. Is this a bug? It never happened before I update to DCS 2.7. Or am I doing something wrong... Thank you guys for your help! AK
Solution Ala13_ManOWar Posted June 22, 2021 Solution Posted June 22, 2021 (edited) Tailwheel lock isn't working until it gets locked, and that's not when you pull the lever, but when the wheel faces the right position, so you have to keep braking/using pedals until it gets locked (wheel facing backwards, aligned with fuselage). You are just taxiing like you have a free castering wheel in a high power tail dragger, that's a bit tricky the firsts times (and always, indeed). If you just bought (or reinstall or whatever) and set the controls in this module, make sure brakes are in the right direction since they are usually reversed by default. S!

cazub Posted July 26, 2024 Posted July 26, 2024 uh sure, it is ONLY an issue with cold start. I understand what you're saying in your post but i do not get the chance to circle around ,back up, or anything that involves my controls. I can lock the tail wheel, i can leave it unlocked, it simply will never get to alignment with the fuselage. It is almost like the front wheels are wheel chocked (they are not though). You can put in right rudder and full right toe break , ease on the throttle. The issue is the plane never goes straight enough nor does it straighten out in order to get the tail wheel to align. It simply is stuck. All actions lead to spinning to the left. About the only thing you can do is slow the rate at which you spin to the left by hitting both toe brakes. ANY movement and the tail wheel goes 90 degrees to the fuselage and you are stuck in the left spin , have to restart or put in a slot that is 'takeoff from runway' or hot start.
Art-J Posted July 26, 2024 Posted July 26, 2024 Can you post a replay track where you encounter an issue? This will help to fully understand what the issue actually is, 'cause I don't think I've ever encountered it in 109. Unlocked tailwheel not reacting to diff braking that is (If I understand somewhat muddy description correctly). Does it happen in one of campaigns (Jagdflieger one, as in OP's case), default missions or your own ones?

cazub Posted July 26, 2024 Posted July 26, 2024 (edited) i have not tried MP or in Campaign , this is single player usually placed in my own mission as client - ground start , meaning NOT at a ramp location. I made a couple videos i'll link when i get home. The start location for me is on the runway , i have another on the tarmac (same issue) but again NOT in an assigned 'parking spot'. **EDIT** - i retried with cold and hot from the ramp (parking assigned) and same result, cold start problem, hot start no problem. I did also note that the cold start, if i lock the tailwheel before i try to move , i don't move AT ALL. If i unlock then relock - the spin occurs. Obviously if i unlock the spin also occurs. Attached is the Track file for the cold start case from parking. twstuckbf109.trk Edited July 26, 2024 by cazub I love to party

The tailwheel starts centered, but seems to just turn 90 degrees by itself. 1:35 - are you sure you have tailwheel locked, and toe brakes released? Some modules default to brakes pressed in when starting, so maybe try tapping both toe brakes lightly before applying power to reset them? If it's not a bug, then it looks like your front wheels are locked up, check axis bindings, etc. Edited July 27, 2024 by PawlaczGMD
cazub Posted July 27, 2024 Posted July 27, 2024 Yup i checked the toe brakes and bindings for the reverse , i check for them being mapped to something other than the pedals and everything looks right. The weird part is it is like ONE of the front wheels locks out and you just spin around on it, but it isn't locked , at least not by controls. I've never figured out a fix so all BF109 missions i just put them hot started. If i'm feeling sassy i can shut it down and start it up again myself and i'm ok.

I see, tail wheel is locked but aircraft behaves like it's unlocked. The stuck tail wheel, well I believe I never came across that problem, I don't know what it might be related to, but yeah, it's not operable when like that. Besides, I see there a problem with exhaust flames, perhaps your graphics drivers aren't up to date? or you didn't delete your FXO and Metashaders2 folders in Saved games/DCS folder? Don't know but that's not looking right. Perhaps @NineLine and/or @BIGNEWY want to take a look at that, even though it'd be probably a thing for a new report since the "old one" was just a mishandling. You might need to upload your logs and all on top of the video. Edited July 27, 2024 by Ala13_ManOWar "I went into the British Army believing that if you want peace you must prepare for war.

Art-J Posted July 28, 2024 Posted July 28, 2024 Cazub, thanks for the track. Couldn't play it as it uses Afghanistan map which I don't own, so I tried to replicate the issue on Caucasus map. I never used "takeoff from ground" option, so I thought maybe that one was causing some issues and that's why I never experienced such a problem myself. That still doesn't seem to be that case, however. During my quick test with cold start from ground at Batumi, using autostart sequence and without any controllers plugged in (just throttling up and down a little using mouse) - with or without lock enabled, tailwheel behaved normally. That brings other questions then: a) does it happen on other maps than Afghanistan? b) does it happen if you test without your controllers plugged in? 1 i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.
cazub Posted September 6, 2024 Posted September 6, 2024 Art-J: Hey I had to take a work induced break from DCS , I'll see if i can reproduce on another 'freebie' map. I remember the issue being present on Marianas, i want to say taking off from ramp in Saipan. I have a little time this weekend I'll try and redo it. A) -- YES B) i have not tried, i have a hotas and rudder pedals , nothing on the Axis assign page shows brakes , rudders , control surfaces etc. , doing anything other than what i am commanding. The first thing i checked was this page looking for differential toe braking or the usual "I just plugged in my controller, now DCS auto mapped throttle and roll to my rudder pedal" issues. How do you recommend i do this, just unplug all and go with keyboard/mouse only?
