Hopefully they can refine the takeoff... I don't think it should be that difficult.

Crosswind add a challenge !

no 10 knot tailwinds then

Here is 300 hp WACO review

 

Here is some impressions of real Waco  take off. Definitely not what we have here. Carenado recommendation for control sensitivity doesn't change much

It's a windy day, the sort of weather I would rather not have for a first flight in a new tailwheel airplane. The Jacobs engine (call it Jake if you want to sound cool) responds instantly to power changes — no need to baby the throttle. Push the stick forward almost instantly after power up in preparation for raising the tail, which occurs after a few seconds of takeoff roll.

At 65 mph back-pressure can begin. My left toe is too far up the rudder pedal and I stab the left brake, swerving the aircraft left of the centerline briefly. After takeoff I lower the nose to reach V _Y, or 76 mph. Once in level cruise and headed for Three Rivers Municipal Airport a few miles west for landing practice, I set the power at 2,000 rpm for a 105-mph cruise speed.

I can't keep this straight when taking off, it starts to roll and and just before 40 knots it suddenly wants to turn left 90 degrees, rudder is very unresponsive, it seems to lag behind your input and when it finally reacts even the smallest pedal depression again wants to turn the plan 90 degrees in the direction pressed.  Another way to explain it is that rudder itself seems to ignore the first 10% of the pedal travel and once you hit 11% it treats it as if you pressed it down 100%.   Not sure if this behaviour is normal but I can't imagine, I tried to mitigate this by pushing the stick forward but makes little difference, it may appear that it doesn't do the hard left quite as badly (not convinced) but it still does and when trying to counter with the rudder it reacts again as described and I'm zig zagging all over the runway.

 

 

It is broken... and I hope they fix it. For me, the lack of a controlled takeoff totally kills it. You can guarantee there will be alot of unhappy new simmers that can't figure out what the heck is going on, as well as us who have been around awhile.

The new simmers will likely just give up and spawn in the air 😄

I will download it shortly and see how it goes on my system. it took me half a day to work out how to get the Azanti Bleriot consistently airborne - lets hope this one is easier 😄 I will report back.

Even if I do find the trick of taking off reliability it is still not correct. I suspect sd_flyer is correct about the CoG issues.

Yeah just spent more time trying to get this to stay straight when taking off and it's just impossible, it's between crashing and just avoiding crashing and if I manage to take off it's usually on a diagonal line between the runway and the taxiway.  Plane looks great, sounds great , it even flies just fine (as little as I have flown) and landing feels right to me as well but when those wheels are touching the ground still either in pre takeoff or post landing it seems to coincide with a reversal of the earth's magnetic fields.

I already posted above how to take off. It's not perfect but definitely doable. You gotta keep you tail down until airspeed come close to 50mph and gently raise your tail. Works with tail wind, head wind and cross wind 🙂

 

Ice does affect WACO!

That definitely is an improvement thank you, I pulled the stick all the way back, it still wanted to go left near 40 knots but I managed to just save it and the rudder seemed to be behaving better as well.

The icing bug is still present as well, even turning icing to visual only doesn't stop it from having an impact.

Thats what I wonder too... They may have to fix the CG (which should be easy...) Where do you find the documentation?

open flight_model.cfg file and decrease the first number in all station_loads by 2. This is my rule of thumb to tame my GA planes that skate around. Works just like real life: move the weight forward a couple feet. So anyone can edit the CG themselves in a minute in notepad once they find that file.

 

oops, my bad, the file is encrypted, cannot access it to edit....

I wish the overhead panel in MSFS had a station load slider to alter CG

OK guys my take off tips:

No wind!

1. Tail wheel locked (assign key for it there is  no click spot in waco)

2. Controls all way aft (to your belly! :))

3. Gradually apply power, slowly dance on rudder

4. At around 50 mph eas up stick to neutral (at this speed rudder become more or less efficient), gently apply rudder to compensate gyroscopic precession and tail lift.

5.  As tail lift slowly bring stick aft and you are airborne!

That works well.

OK you are definitely on t something with your CoG find, that was a good clue.  One trick seems to be to compensate with nose up using up trim rather than stick back. This allows you to take-off stick neutral which gives a few more options.  

Your method above is good, I found the following method also works and is easier for me.

1.  lock tail wheel as above

2. add 75 lbs rear baggage (see video)

3. set trim to FULL nose up to compensate for the excessively forward CoG

4. initiate take off roll at about 50% throttle

6. once airspeed live, apply 100% throttle and take-off relatively normally

7. trim immediately after take-off for for level flight

 

Example take-off:

 

 

Of course a downhill runway helps as well ...

And now the plane is a write-off after that belly landing.

And they’re going back to porting over the previous planes, which I am happy for, but they should have started here instead of the detour and subsequent delay.
