Lucien,
Painting the spinner spirals on the plastic scale models is very different than painting the spinners on the larger RC aircraft.
For the RC aircraft spinners I start out with a white spinner and lightly sand it to give the paint something to grip, then I use special thin masking tape and mask off the area to remain white. Black paint is then lightly sprayed on the spinner until the whole thing is covered, I wait a few minutes and then spray it with normal paint flow from the airbrush. (The reason I start with the light mist coats with the black paint is to avoid paint from bleeding under the masking tape)
After the painting is done remove the masking tape even before the paint is dry, if you wait until the paint is dry and THEN remove the tape sometimes the paint has a ragged edge to it and will wear off quickly. The final step is a good flat coat to protect the paint job.(Flat clear works best because the starter cone gets a better grip on the spinner when starting the engine)
Painting the spinners on the plastic scale models is not so easy since it requires a steady hand and some skill to get it right.
Some spinner spirals on the full size Luftwaffe aircraft were hand painted, a few years ago a Fw 190 D was recovered from a lake in Germany in very good condition with the paint job intact and you can clearly see the spinner was hand painted. In one of my books there is a picture of a Luftwaffe ground crew hand painting a spiral on a Bf 109 spinner.
So I would not worry very much about trying to do a ''perfect'' spiral on your spinners.
The spirals were ordered to be painted on all Luftwaffe fighters in 1944 for safety reasons AND to serve as a distraction to the gunners on the bombers.
When the Luftwaffe was forced to use foilage for camouflage to protect its fighters from possible air attacks a few ground crew were killed by getting hit by propellers because of the noise of several aircraft being parked so close together in their forest hideouts the ground crew needed a way to quickly see which planes were running and which were not. The spinner spiral was very eye catching and gave easy visual warning and probably saved a number of lives of the ground crew.
Later it was discovered the spirals could possibly help the pilots while attacking the bombers by distracting them at critical times during combat.
Years ago I read some combat reports written by B-17 gunners about fighting the Luftwaffe over Germany and I remember some gunners did notice the spinners but no mention was made of any effect it had on throwing off their aim.
Later I will post some pics of one of my RC planes with the painted spinner on it.
Karl,
Your Ta 183 looks like its off to a great start!
Did you have any trouble fitting the Fw 190 cockpit parts into the fuselage?
My Amtech Ta 183 is already broken without really starting on it yet, while attempting to get rid of the warp in the bottom wing half the wing snapped in two. I can fix it but this should not have happened, for the price of that kit you would expect straight unwarped parts.
