FW-190

I've liked the look of dz1sfb's popular warbird designs but the foam, motor and lipo weren't something which I normally use or can get hold of so I've scaled the Sketchup model up by 25%. This gives a wing area of 1.25 x 1.25 x 150 = 234 sq in. All the 0.2" tabs and thicknesses are now 0.25" and the span has increased to 37.4" so it's very suitable for 1/4" foam.

I've tweaked the servo cutouts to suit 9g servos from China and made provision for a 4mm carbon rod main wing spar and 3mm carbon tail spar, otherwise everything remains the same.

I'm predicting the need for about 150W of power from an 8" to 10" prop. My chosen setup is going to be:

Turnigy 2830-1050kV
Turnigy 20A-25A ESC
Turngigy 1300maH 3s lipo
9 x 6 APC style prop
6110 Spektrum RX
2 x 9g HXT servo

The photos show the framed up model from 6mm depron awaiting airbrush and paint. In this configuration with the RX, ESC and lipo also chucked on the scales its around 16oz RTF which seems reasonable compared to my other shockie design built from 6mm Depron. More photos after the festive season and airbrushing if santa got my wish list.

The Sketchup model is attached for anyone wanting to shuffle the parts around to suit different foam sheet sizes from around the globe. Mine are based on a Phlatprinter 3 running the stock 1/8" bit with 6mm Depron in the European size of 700mm x 1000mm giving a safe area of 26" x 35". If you use my CNC files, it's best to cut the fuselage parts first from a sheet, then cut off a couple of inches of scrap from either end. Use this taped to the second 'wing' sheet to provide 'tails' so that the larger 37.5" cut can be made without running off the end of the rollers.

Big thank-you to Ken for the original design.

Season's greetings

Made a bit more progress on the FW-190 over the holidays, just waiting for the UK winds to drop below 30mph for the maiden flight. Slightly concerned over the small tailplane area ..... fingers crossed!

Great work!

 

My favorite warbird! Nice work. My problem with warbirds or any plane for that matter, is my painting skills. Imagine a two year old with a loaded airbrush.

 

Thank-you for the kind remarks guys.

I found a brief gap in the weather to try it out at a local park despite drizzle in the air and gusting about 15mph wind. A few test flights were a non event until a broken prop stopped play and I had no spares with me which forced a return to warmer surroundings.

Performance is spirited without being ballistic and my concerns over tail area were not noticed at all. Camouflage works well with an overcast sky, slight mist caused by the drizzle and low passes in front of the trees! Dog walkers were entertained by my noises of a BMW engine and machine guns during the low strafing passes. The only improvement will be a tiny amount of side thrust to cancel a slight pull to the left and no rudder to cancel it out. Definitely one for regular trips to the flying club.


dhc8guru: Just dive in and have a go at the airbrushing. I think it's just another of the dozens of skills needed for the hobby. My efforts aren't brilliant but they look ok twenty yards away on a low pass. It's probably the chance to learn, improve and try to master all these skills that keeps us addicted to scratch building planes. If it was all instant perfection, I'd get bored very quickly.

 

I have tried many times. I limit myself to single and maybe two color paint work. I do need to get another airbrush, rattle cans are too expensive.
I know the limits of my talents in RC, I can do everything except paint. I need a teacher to show me proper techniques.
