Those of you interested in the Jack Devine Model line, here's a recently completed FW-190A. She took over a year to finish, only because of my never-ending "honey-do" list, though many, many extra's added to this project increased the building time tremendously.

For those familiar with JDM, they are foam planes, then finished with conventional methods. Flying characteristics claim to be outstanding.

Some specs:
Hermann Graf's version of Sept. 44
82" wingspan
Zenoah G-62 (she'll be a rocket ship!)
Robart gear
Painted with automotive basecoats and clearcoated with PPG Flex-N-Flat
Graphics handpainted or printed on decal paper
Flaps
All bombs drops independently.

here's the kicker---weight: 26 lbs. Yes 26. She took a full 2 lbs. of lead in the nose to balance. Normally this is not typical. Weight should be 22-24lbs.
I'm hoping with the washout and flaps, she will still fly and land well. That day is scheduled for this Thursday@ Markham Park, Florida.

Nick,
She looks great. I have been flying my JDM FW190 for about a year and have had great success with this model. Mine is about 24 lbs on a Fuji 50. I find it lands best with wheel landings and getting the flaps up right after touch down. That really makes it stick. In the air it grooves like a pattern ship. Good luck with the first flight.

Forest, I mentioned you at the other site.
I thank you on providing the much-needed answers to my many questions regarding the building of this model. I followed your building thread through it's beginning.
Hopefully those two extra pounds won't destroy it's docile flying characteristics.
Looking forward on flying with you at Mac Hodges place this June.

Thanks on the compliments guys. Only hope she's not that proverbial "lead-sled".

LDM... Flush rivets are burned with a 20 watt Weller soldering pencil, which has a 1/16" piece of brass tubing crimped onto the tip. These are applied after the top coat, then steel-wooled to remove excess flashing (or the mushrooming of primer/paint). Airbrush over will the color base. A 36" steel straight edge with tape looped and pressed 1/8" along the panel line ensures a straight row of rivets. One thing I despise is viewing a row of rivets which make you sea-sick.
Raised rivets - Pica's GLU-IT, right out of the bottle. I modified an old SIG primer bottle with a hypodermic tip.
Gun Hood - Evercoat lightweight filler. Built up the pattern with masking tape and apply this Bondo to desired thickness.
Gun Bulges - top's from my anti-perspirate containers.
Hatches - .015 plastic. and air-conditioning duct tape (aluminum type). I also use printer's lithoplate, like behind the cowling.
Aft cowl vents - .016 aluminum bent in a small vise.
Exhaust tips - K&S streamline tubing mounted in a block on wood and secured into the 1/2" firewall.

Nick............another professional job to go with the rest of your "Squadron"....really looks like you spent some time on this one..........I am looking forward to being out on thurday for the maiden flight............looks like we'll have a nice weather day with winds out of the east @ 10-15 knots............Bill........

Thanks Bill,
Yes, I've been monitoring the winds and they look favorable for tomorrow.

Just putting the finishing touches on her with balancing the prop and spinner/backplate, cycling batteries, securing clevis's, etc.
Charlie was over last night for the final CG balance, so I'm confident that is set per designer. Tonight I'll set all throws and load her in the vehicle for Thursday.

Hope to see you and Keith there.

She flys!!!!!!!! I only wish I could provide the video clip. It's on my 8mm, but I've got no way of presenting it to you fellow's.

Here's my story...

As planned, I went out to Markham Park, Fla. yesterday afternoon expecting the high winds to subside. They never did and to make matters worse, cross runway.

Not too be discouraged, I set the plane up alone and spent about an hour checking linkages, gear, batteries, fuel etc.

As 5:00PM approached, winds shifted down the runway and all my flight crew had arrived, so I was determined in get her airborne.

The G-62 start right up, idle set. Man... the spiral nosecone is mesmerizing at slow speeds! Pulling and holding elevator, I taxi out onto the runway. Now lined up, and in typical warbird fashion by holding elevator I gently accelerate the engine. I expected a good pull to the left, using the bigger engine and a 22 X10 Menz prop, and I got it. Nothing drastic though, as slight right rudder straightened the roll out. Still at 1/4 throttle and rolling for about 20 feet the tail became light and lifted. Now relaxing the elevator, I'm up on the mains and advancing the throttle - She's right on runway center and tracking like freight train! I'm already thinking this is going to be a sweet take-off. No pitching or deviation, though I still continue to hold slight right rudder. Now at full throttle, she's hauling butt-beautiful! I slightly bumped the elevator and away she goes, lifting up into a beautiful climb. Gear up immediately. Before I made that first turn, I had throttled back down to 1/2. The nose continued to point up, letting her climb for several seconds. First turn downwind and at a safe altitude, she required slight down elevator and slight right aileron trim. Jack and Steve - your initial surface deflections were dead on!

Now flying level, I'm beyond that stress point and relaxed flying begins.

I checked the CG in both upright and inverted attitudes. Upright and fully stalled, she simply drops her nose-no tip stall or snapping of any kind. Inverted, she requires a fair amount of up elevator to maintain level flight. Maybe too much nose weight? Anyways... I continue to fly for several minutes and then turn the transmitter over to my two veteran R/C friends, Paul Tirone and Mike Haspas. With a combined R/C experience of five decades, we concluded this is a very solid flying design. No surprises, agile, but yet, solid-on-the-sticks.

Mike reduces air speed and asks to drop 1/2 flaps, then full flaps. I say "yes", he does. At half flap, the nose drops more than usual. O.K., not bad. At full full, the plane goes into this hard left turn/spiral! I mean ugly! Immediately its shouted "pull the flaps". He does, and the plane levels out and he resumes flight. Thank goodness we had altitude. Upon retrieving the radio back, I notice additional right aileron trim is required- lots of it. I feed that in and decide to land.

Before dropping the gear, throttle is increased. Gear down-no significant pitching. I must land at 1/2 flap or no flap. Being at 26 lbs. I insist on utilizing flaps. At final, the plane is far away, but flying directly at me. With the nose pointed slighlty down, 1/2 flaps are deployed and throttle is massaged. She's looking good - beautiful rate of decent.

At about two feet from the deck, the nose raises and I over-compensate by feeding too much throttle. She's now about to land a bit faster than I would of liked. She touches down, but the nose then comes up and I inadvertently feed too much elevator , not relaxing it [], as instructed by Paul Tirone. The result was a bounce that fortunately, didn't damage the plane and/or gear. It wasn't pretty.

Once retrived, I notice the left flap hanging down. What's this! Evidently, the rod was not screwed enough into the Robart clevis. Even with a backing nut, she still pulled out. I had 1/4" of threads into her - not enough.

I quickly fixed that and once again, took to the air. Same run out, same take off manners. This flight was to be special though. Mike Haspas is an expert at programming the JR 8301 radio. Once airborne and me holding the transmitter, Mike accessed the menu's and corrected all the trims, mixing, and surfaces deflections. Guy's, this is the only way to solve flight problems quickly and accurately! Just assure your partner thoroughly understands what and how to perform any changes. Gotta love computer radio's!

So now, upon dropping 1/2 flap, full flap (40 degree), gear or whatever, the plane tracks beautifully with a slight nose down attitude.

Two additional landings were made that afternoon, both grease jobs.

Overall , I am extremely pleased with the JDM 190's flight characteristics, performance and overall behavior. Utilizing the G-62 engine, (IMHO), was the right choice. She's fast, but not that rocketship I expected. I imagine the airfoil will only allow a certain max airspeed -unlimited climb rate though. I feel she flies very similar to my Ziroli Zero - solid on the sticks, predictable. At 26lbs. it's certainly not a thrash-around model, but performs all the maneuvers I desire, including inverted flight and low, rudder circles. I may drill-out some of the lead shot within the nose, as she requires more up elevator to maintain level flight while inverted. No big deal though.

I highly recommend this design to anyone and certainly to the beginning or intermediate warbird pilot who desires an easy to fly warbird design. This, coupled with the manufacturer's support, is a win-win situation !

I thank everyone for all their support and providing that invaluable information that led to my success with the JDM 190.

Hope to see some of you at Joe Nall in 2 weeks. I will then be dropping bombs on some unexpected target !
