Could you record a take-off trial and post it?

Could you record a take-off trial and post it?

I work on it. The last one was pretty obvious there (not correcting strong enough in the middle), I will try to get one with the really erratic behavior.

100% "Rollhilfe" (Roll or taxi assistance) had been activated by default... does that have any effect?

 

[Fabri91]

A video would be better, I think. I don't know if without the module we'd be able to play back a track.

Regarding Rollhilfe...no idea. It might have interfered somehow...

 

[Urwumpe]

I think it should work, since we also have the AI plane versions there.

So far, just watching the starts myself from third-person perspective is pretty helpful. First of all, being really aligned with the runway does not seem to be that easy, I am always pretty far off compared to take-offs with the A-10C.

Next: Without roll-assistance, the plane is more likely to roll because of yaw inputs, but also the problematic behavior now starts more reliable. It looks like plain oversteering at higher speeds, I ran off the runway on one wheel in the two attempts in the last playback and crash as soon as I leave the runway.

Conclusions:

No opinion on "Rollhilfe", it doesn't seem to be the direct cause, but it feels like it is hiding bad parameters from me until it is too late to compensate.

As already expected, the higher the rolling speed, the more careful you should be on the rudder inputs. Engine torque does not seem to be any factor, the RPM had been constant for seconds when the plane gets out of control. But without Rollhilfe, you feel the torque at least. Maybe better during the experiments to keep it disabled.

Primary goal is now trying to stay centerlined as long as possible... the youtube video about the take-off implies using the rudder already from 50 km/h on, I believe thats too low to have any control, even with the prop wash.

EDIT: But the claim that the Fw 190 is tame during taxi can be confirmed. The tailwheel is a bit surprising at first, but once you are used to its behavior and stay at low speed, the Fw 190 rolls very well and can be controlled without problems.

Next try, clearly oversteering.

I'm not so sure about that...sure, it's no metal fighter, but I've seen towplanes, with bicycle landing gear, lift their tail on a stand still using only the propwash.
It's a very significant contribution, especially if you then add the 50 or so km/h you're travelling at.
Try it in the A-10: even locking the nosewheel, some sort of yaw control is already possible way before the speed indicator on the hud starts reading speeds over 50 knots, and due to gear configuration it's a much harder plane to yaw in such a situation.

Possible that you are right there. I also noticed at 2 AM last night in the video, that the plane got out of control, when I accidentally applied right wheel brake with right rudder at about 150 km/h.

Controlling the direction just with rudder seems to work, but you need quite some deflection early to stay on track. Also, you really need to look at the turn indicator during rolling, just observing the runway does not warn you early enough of the problems.

And I really recommend disabling "Rollhilfe" in the options. It really only made things worse IMHO. Its now already earlier harder to stay on track, but the problems don't appear so surprisingly.

Ok, thanks to ED's bonus system and my full-price purchase of the A-10C beta waaaay back in time I'll be able to join you in your take-off difficulties.

:rofl: I'll maybe do the same with the F-86F towards the end of the month, should my financial situation stay relaxed.

 

[Fabri91]

For the Sabre I'll most likely wait for a sale...I'm not particularly interested in the type, but should it be available for 10 or so €...on the other hand some reserves are needed should the F/A-18 debut unexptectedly.

I am not sure about the F/A-18 there... while carrier operations would sure be very cool, my interest in modern aircraft is currently well-satisfied by the A-10C.

Also, in case of the F/A-18, it really depends on the version... C/D? Forget it, I don't want to be refuelling every five minutes. :lol:

The Sabre would be interesting because it is one of a different era... carrier Ops with the F-8 Crusader would also be more interesting than the F/A-18 (Sadly, there is no module for a Crusader in development).

 

[Fabri91]

it's difficult to take-off.

3 pilots dead, with 4 destroyed aircraft...I never botched a take-off in the Mustang, engine management issues aside.

So, it is not just my digital high-torque double bass feet causing the problems. :rofl:

 

[Fabri91]

Reasonable success! First flight accomplished, but both take-off and landing would have required a change of underwear.

Video is being uploaded, should take 3.5 hours :/

My 8 minute video of the failure last night is also 600 MB large, because of using 1080p resolution... took my laptop also a while to render, despite me usually playing DCS in that resolution.

 

[Fabri91]

Meanwhile, at Batumi:

For taking off I found Wags' tutorial video especially helpful in one point: notice the amount of right roll that is kept more or less constant. With that, take-off was almost straight.

 

[Urwumpe]

Meanwhile, at Batumi:

We Germans call that [ame="http://de.wikipedia.org/wiki/Fliegerdenkmal"]"Fliegerdenkmal"[/ame] (pilot memorial) for a reason. :lol:

 

[Fabri91]

And finally: my graceful first flight!

720p version should be available shortly.

 

[Quick_Nick]

Is the difficulty a bug or a feature?
Wikipedia has a bunch of anecdotes comparing Fw 190 to other aircraft and it sounds like takeoff and landing are stable and easy. If the simulation is accurate, I sure as hell don't want to try a Bf 109 which is supposed to be a death trap by comparison.

 

[Fabri91]

Well, the Fw 190 is relatively easy to fly...compared to other contemporary aircraft.

That is, a bicycle geared aircraft with a relatively big spinning mass at the front (the propeller) and a long nose that makes it impossible to see where you're going during take-off and landing will inherently be a difficult plane to fly in those conditions.

Other aspects however make it an extremely user-friendly aircraft:

• Fuel gauges placed where they can be seen (i.e. not behind the seat!)
• Single-lever engine control
• Extremely easy start procedure (never failed once, for now)
• Very simple flaps and gear controls

For example I've found it much easier to manage the engine temperature, where in the Mustang I've managed to seize it countless times.

Both aircraft have their pro and cons.

 

[Urwumpe]

And of course: A display for the available ammo... Very simple communication system...

And did somebody already notice the indicator for the flap angle?

Getting better... again crashed the take-off, but this time all went fine until my rudder pedals slipped. Right roll is really important, but you should reduce it with increasing speed, I think... 170 second repair pause, before trying again.

---------- Post added at 07:35 PM ---------- Previous post was at 07:19 PM ----------

OK, crashed again... using right roll is really making the take-off better, I just need more feeling with the rudder. All went pretty well, but at a point I applied too much rudder and then lost the fight over the next 5-10 seconds of take-off.
