It's done, and available in the swap pages.
As promised, it has retractable Landing gears, and moving trailing
edges.
I certainly am not a mixing expert, so I anxiously await
to see what the tweakers can produce.

The learning curve continues, so I'd like to thank some very smart
forum members for helping me finish this.
Inky of course, for sharing his retractable legs knowledge.
Rimmy the physics genius, What I could not solve in several days of tweaking he did it overnight.
And Opjose for his input in creating the model.


I will annotate the control surfaces on this thread later.

Awsome

Just downloaded The Best Looking Plane Ever !!!!!!
Thanks To Every One Who Made This Plane , You Guys Are Just Toooo Much !!!!
I Know It Has A Fue Bugs To Work Out But Im Just Amazed How You Guys Keep ,
Out Doin Youre Self.
Thanks For Keeping Flying Fun !!!! :D :D :D
 
Looks fantastic, but I can't get it to fly to save my life. It just oscillates wildly once in the air.
 
efink, you have the 3.5.044 dont you? i DL'd this B2 earlier, and it was AWESOME! thank you! when i downloaded 3.5.044 it wont fly now! :mad: :mad:

heres what i did phrank:
i switched the brakes over to elevator, only on when down elev is applied. this is how the jet guys do it at our field, works great.
made the rudder/v things on the side have same deflection on top and bottom, then got them on seperate channels. i did this, so they work like rudders, but when the knob is turned i get 60% of both of all 4 surfaces to act like flaps. orginally had 100, but it literally WOULD NOT land. so i cut down to 60% and made the thrust idle at .8lb.
also, i cut down on thrust bigtime for scaleness to 10lb.
 
Sorry to hear about the B2 misbehaving on some.
* Snapping wings: Model is fast, extreme elevator input at
high speed will stress the wings.
Possible solution: As in real life, throttle managemement is
the key, WOT on takeoff and straight flight, ease off on turns and
extreme maneuvers. Low rates is also helpful in taming the bird.
If this is not acceptable, then edit the model and increase the wing strength.
* Wild oscillation: Check very carefully for any orange warning messages
on the lower left of the screen when the model was imported. It's
possible your version of realflight substituted a component, this can
throw-off the model physics if so.
(I can't recreate this scenario)
* Won't fly after upgrade: Try completely deleting the model using
"Manage User Files" under Simulation menu tab. Re-install the
model.
(I can't recreate this scenario either)

By all means go ahead and tweak the model to your preference,
just like in the real flying fields, everyone has their own flying style, and
adjust their transmitters and control throws differently.

IF there are any tremendous bugs with the model itself, I will re-issue a new
version. Otherwise I believe Aircraft Variants will suffice. If you have something
you feel worthy of sharing I'd like to see it.

Looks good! I haven't got the time to fly it yet, however. How do you increase the wing strength?

shoot....ive already done modified it.
could i upload my version, delete it from the sim, then re-download my version for the same effect?
 
I've downgraded my Realflight to version 3.50.33. I did notice a degrade in Aileron control, but model was still very flyable. I then upgraded back to 3.50.44
but am unable to recreate the problems experienced by other forum members.
I'm not sure where to offer further tips past this.

On editing the model:
Choose "Aircraft" menu item and Select Edit right below "Select Aircaft" tab.
The wingtip seems a bit weak, so click on + until you see Wingtip selection
as the attached picture. Enter a value above 100.
If you still have snapping wings problem, increase strength of each wing
segment in sequence from Tip towards the fuselage until you are
confortable.
Save the model as different name from the original in the case you
make a mistake.

I hope that was helpful,
Frank...

Thanks! I've had several high-powered models that I need to do this to, and I didn't know how.
Thanks,
BladeCP02
 
Try the EP version.

For those with troubles with the turbine, try this Electric Power version variant
and let me know if you get a working model.

If this works then I'll replace the version on the swap pages with this one.


UPDATE::::
Nevermind, model has been removed from Swap Pages.
All my testing was done in Photofields and I did not notice the problem
until I switched over to Flightschool, problem was recreated at will.
Looks like some nasty turbulence in the trailing edges.

I would not have expected the physics model to behave differently
on a Photofield vs. 3D airport. :confused:
Knife Edge, what gives?

I will re-post when it fly's well.

I apologize for any inconvenience,
Frank...

As mentioned previously, the craft is shaking itself apart at high speeds.
The reason the wings are breaking apart shortly after taking off is because
I assigned each wing segment to the model's ~CS_LMW and ~CS_RMW.
When the wingtips break away, so does the entire wing of the model.

The following is not a solution, but it illustrates my assesment:
What you can do to fly the plane until I resolve the shaking is to
Edit the model and do not assign a component to
"Wing Wingtip", "Outermost Wing", "Middlemost Wing" and "Innermost Wing"
(See attached)

Wings will stay on, but you can see the violent shaking I am talking about.
As the next part of the wing breaks away you will loose some control
of the plane, but it will be somewhat flyable.

Alternatively you can assign these wing segments to parts of the plane
such as ~CS_LMA, ~CS_LMA1, etc to see the breakaway in action.

Now that I know what caused the original troubles, I'll figure out if changing
the airfoils will alleviate the symptoms.

Time to sleep....

That's not really the problem with the model.

As far as G3 sees it the fuselage is too short.

It wants to flip the model end over end but the plane is somewhat statically stable, but HIGHLY overpowered resulting in the characteristic flapping up and down when G3 doesn't know what to do with certain configurations...

I'm e-mailing you directly....
 
i was going to downgrade back to .033 but the helis just fly SO MUCH better :(
ill see if i can tweak it to get it to fly right....
 
It's back...

Thanks to opjose's insight, the model is flying properly now.
I've tested it in both Photofields and 3d Airport and it "feels" right now.

Before downloading this version, please completely remove the old model
through "manage user files" menu option in the Simulation tab.
If you've made any variants already it might be best to start over, otherwise
save your variants before removing the old model.
 
Just downloaded the new model, wonderful. The moving parts, detail, and overall finish is great. Flys just as well. Cant comment on how it use to fly as I did not get that model, but this one flys great. :)
