Anyone with one got some advice? How they fly, durability, service.

Status: offline 		Just recently purchased a FW_190. I built it over the course of a few weeks. It took me no more than 10 hours of actual building time. I was pretty impressed with the overall turnout. It is exactly what they said: not pretty, but good enough. I haven't flown it yet, but I will try to reply afterwards and give an update. I need to rebalance slightly.

The Corsair is a bit slower than most Scale Combat planes while the Fw-190 with a good .25 is a real screamer.

My personal favorites are their Zero and P-47:

All of my cowls are PETG pop-bottles pulled over my own home-made wood molds with a heatgun. That humungous Jug cowl's mold barely fits in a 3ltr bottle.

Status: offline 		Larry,

Thanks for the compliment!

My JKA planes were all built as per the JKA instructions (including all of the Strapping Tape and dowel-spar reinforcments), with one exception:

I use EconoKote or TowerKote covering instead of the recomended Packing Tape for covering. Then that is scuffed with 000 Steel Wool and painted.

The Zero pictured is painted entirely with gloss Rustolium paints(Dark Hunter Green, Smoke Gray and Black). The Rustolium colors are fuel proof and can be used as-is with no clear coat.

Rustolium metalic colors, flats and satins are NOT fuel proof! Only the gloss colors are.

The P-47 was originally painted with 21st Century Olive Drab topsides with Rustolium gray primer undersides and Yellow Rustolium tail with a coat of Krylon Acylic Satin Clear. Most of the 21st Century Olive Drab on the wing chipped off in numerous midairs. So, those areas were repainted with Testors SAC Olive Drab and cleared with the Krylon Acrylic again.

Not all Krylon clears are fuel proof - ONLY their Acrylic Gloss and Satin clears are. They also have Enamel and Laquer clears that ARE NOT fuel proof.

Hope this helps,
D

Status: offline 		Yes, I spray on a light coat of 3M77 (NON-Acetone Formula) and let it dry for at least an hour before ironing on the covering.

Also forgot to mention 2 things:

1) I always fibergalss the center 6" of the wing with 3/4 oz. cloth and epoxy. Sparying 3M77 on, then laying the 'glass cloth on that and squeegeeing the epoxy on with an old credit card really makes for a neat and hassle free job.

2) All of the trim and markings are/were done with "Sign Vinyl". This stuff is identical to "Trim Sheet" but costs only about $13 for a 30' (yes, 30 FEET) x 15" roll.

Here's my JKA P-51D. Its the only one I built using the Coro doublers for the cowl (and it does work great this way!).


21st Century Aluminum this time with 21st Century Olive Drab anti-galre panel with Sign Vinyl trim and markings. The 21st Century paint dries hard as a rock (TOO hard) and that leads to chipping. But hey, Tower had it on sale for $2.95 a can...

Status: offline 		I have two J.K.A. models. One is a the Coursair the other is the FW 190. Both very nice fliers with the Norvel 25. I would recomend the fw190 for combat since it is lighter and faster. I used tape originaly on both models but after an hour or two the tape seems top allow fuel to leak and the tape began to delaminate. I would spar the wings and use a ultracoat type covering from the start and save yourself the hassle of recovering later. In the future I will also spare the tail at least.
A few weeks ago we had a combat meet and the only two planes remaining were my FW 190 and a friend of mine who had an all couroplast plane. The other built up planes were either totaled or disabled enough to not be able to fly for the rest of the meet.
Happy Flying
Doug
