Oh...I can see the real improvement Keith... Congrats Mate.

Now the next step at your modelling is to use a masking tape for all strips, bands and other elements ( cockpit conopies) painting.

Thanks Wojtek

Trying it on the Dora Taped the complete canopy apart from the edge that requires painting

Or keith, you can save the "leg shaking" by trying to get the tape right nad just paint your canopy with acrylics then use a toothpick to scrape off any excess that goes outside the lines. I used this technique on my p61, I think it came out rather well... Also, if you get a plastic "gap" from manufacturer error (Canopy doesnt touch the frame of the cockpit and such), you use elmers school glue (PVA) and brush it into the crack then wipe away the excess and let dry then paint, also did this on the p61 canopy as there were many gaps.

..Um, me again Keith... I asked Wojtek (Wurger) if he could confirm or deny what I said about those doors -I'm wrong again!!!
In all my photos the doors appear as mentioned - all A-3 and 4 retracted, A-6 open, so I presumed (always dangerous...) that this was the norm. Wojtek mentioned however that they were able to be set to either position according to will, regardless of variant...

Sorry for putting you crook once again!

looking good.. but i see what you missed to paint..the exshaust cover..that is always in a differnt colour as its heatresistant steel
but you are doing great i love the A3 been working one one for many years but that is a few scale bigger than yours

keep up the good work and always nice to see a black 3 ( ours is also black 3 )

Great pic Mr.G! Looking forward to seeing that bird finished!

[Junkers88A1]

it will be done by january ( we hope.) as that is the schedule for it to go on display

I am not up to all this lingo.All i can tell you is a plane is a plane ops

Trim tabs. Not a dumb question. When the aileron goes down that increases the lift of that wing. It flies up because of the added lift. The opposite aileron goes up spoiling the lift on that wing so it goes down. The ailerons are set up so they deflect differentially. In other words, it doesn't take as much down aileron to make a wing fly up as it does up aileron to make the wing fly down. So, they deflect with differing throws that is set into the linkage. The ailerons control the airplane around the roll axis which is an imaginary line drawn through the longitudinal axis of the fuselage nose-to-tail. If the pilot is in level flight and takes his hands off the joystick the airplane may roll left or right. No airplane is perfectly stable around it's yaw, roll and pitches axis. So, to counter this instability trim tabs are hinged to the ailerons and connected to a cable and drum system. The drum is usually in the cockpit with a handle attached for the pilot to move. The trim tabs do exactly the same function as the ailerons. Move the trim tab down, the aileron goes up because the area of airflow over the aileron and trim tab is changed with trim tab deflection that increases lift in that area of airflow. Unlike the aileron/wing differential of lift to drag components, the trim tab increases aileron lift in either direction of throw. This allows the pilot to set his ailerons, using the trim tabs, to trim the airplane for wings-level flight. Otherwise, without trim tabs he would have to maintain constant hands-on pressure on the joystick either left or right to maintain wings-level flight. Trim tabs allow a hands-off trimming of the airplane to maintain stable flight characteristics. In formation flying this is essential. The elevator controls movement around the pitch axis which is an imaginary line drawn through the wings from tip to tip at the center of gravity, which is at or near the center of lift. The rudder controls the movement around the yaw axis which is an imaginary line drawn vertically through the fuselage at the center of gravity. The elevator and rudder are also equipped with trim tabs for the same reason as the ailerons are.

Last: Control tabs. These are similar to trim tabs but they are there to assist the pilot over-come control loads on the feathers (ailerons, elevators and rudder) at high speeds. With high speed comes high pressures on the feathers and that translates to heavy joystick loading on the pilot. Control tabs are rigged to deflect the opposite direction of movement on each of the feathers, but typically just the ailerons and elevators. This adds an aerodynamic lift component that assists the pilot in moving the joystick in the direction he wants to move it to. Later on hydraulically boosted feathers came into being and are common-place on high performance airplanes or very large airplanes where the pilots would no way be able to move them with normal human strength.

Thanks guys

Mods can you delete this please messed it up

Thank you

No fair...Guttorm....you get to play with all the best toys!!!

Great additional work Keith, that extra work has improved your model big time, good on you for taking the extra step mate!...well done.

[ellis995]

Thanks Wayne

It's down to you guys on here

Looking really nice Keith. Good job.
