marcus4hire Posted May 21, 2015 Posted May 21, 2015 (edited) Greetings All: So my Dora is coming along nicely. However, I have one issue I am trying to get to the bottom of and that is turning the plane while taxiing via left/right brakes. Does anybody else experience trouble getting it to turn to one side or the other, seemingly at random? I am GUESSING (still doing some tests) that it has to do with the weight and fuel contents. If I have it anywhere over 50% or so full it seems almost impossible to get it to turn cleanly. Is this normal? If I have a belly tank I notice that I have to really gun the throttle to get it to turn. Taxiing can take several minutes and the most I can get is a fraction of a turn. Let's say I am turning 90 degrees with a moderate fuel load. I have to darn near push the throttle all of the way and inch it into the turn. Throttle up, moving, turn, stop, get moving again, turn, stop, etc. But when the plane is light I can drive it around just like a car. Is all of this just from extra fuel load? I haven't even tried it with 100% fuel. I think, so far, I haven't had anymore than 70%. Any thoughts are appreciated. I'm gonna go fool with it some more and report back. ETA: Nope. I just taxied all over the place with no real trouble at 100% fuel. Maybe a hair more throttle but that was all. Had some problems right at the end but after a turn or two it went away. Do the brakes get hot?? Are they just 'iffy' at times (assuming you have random failures on)? I have read that planes of the era didn't have the best brakes. Is this what is being modeled at, seemingly, random? Edited May 21, 2015 by marcus4hire

Is this what is being modeled at, seemingly, random? I know that the manual talks about getting the tail wheel sometimes getting stuck and needing to unlock it. When taxiing, first unlock the tail wheel, otherwise it will be impossible to make turns. In order to do so push flight stick forward by approximately 3cm. In case the tail wheel does not unlock, it shall be tried to unlock by alternating brake application and simultaneous forward pushing of the flight stick. I'm assuming here that you are already aware of the basic tailwheel locking behavior. I'm not sure if the above notes from the manual are actually modeled in some way, or if they are just taken from a translation of something original.

I knew the bit about pushing forward to unlock it but guess I read over the part about it getting stuck. That should answer it as I recall I will alternate between the two brakes just to see if I can get some type of response. This must unlock the tail wheel and get her turning. I very much appreciate your taking the time to quote that. Back to the manual for me!
MarkP Posted June 10, 2015 Posted June 10, 2015 To lock the tailwheel you have to pull the stick back all the way. It will unlock if you release the stick. So to taxi: give it a bit throttle, not too much, otherwise your brakes arent strong enought to "counter" the torque of the propeller. Then to turn, release the tailwheel by keeping the stick to the middle and turn with the brakes. If you are facing the desired way you want to go, brake the other wheel to drive straight and then lock the tailwheel by pulling the stick all the way to your crouch. Thing is, you cant lock the tailwheel while hard cornering, the tailwheel must be straight at first, thats why you brake the opposite direction. Then to drive straight, you keep the stick pulled back.

Grundar Posted June 13, 2015 Posted June 13, 2015 I find the easiest way to avoid the Dora's tailwheel locking and unlocking and the brake dancing you can get caught in is to simply lock it from the ramp. I just keep back pressure on the stick and use the brakes in small taps to orient the Dora as required. Usually when I hit the runway I will unlock it advance a bit, lock it, make sure I am straight then power into a take off. I am using the twist throttle on my stick though I can't justify (to the minister of finance) rudder pedals...

I thought the twist rudder crowd had it bad ... minister of finance needs to give you an allowance or a one time grant for some new sim equipment lol.
