jetfool,
I have both kits, the Platt kit is by far more work, but very true to scale, the Holman, fiberglass fuse, and foam wings, plans are very limited as far as information, I'm going to try and fit PLatts wing(build up ) in lieu of the foam. they are very close in dimensions.

Fw190 Retracts
Guys,
If you decide on which FW190 to build, you may want to
contact Sierra Precision for the Scale Retracts. They are
coming out with Retracts for the 80" to 82" Size.
They will have the functional down lock and all the
proper angles.

Holman 190
Jet, I had the Holman 190 and it flew unbelievable, with a OS BGX it would shred the sky. If you build the tail light, it should not come over 22 lbs.

Not to further confuse things, but there is also the Vailly Aviation FW190 and the Don Smith FW 190 that are both around a 90" wingpan. Precision Cut Kits cuts the part for either, and Darrell at Sierra Precision makes a set of retracts.

tempest,Ithought about don smiths FW190 but haven,t seen his plans. I have the platt zero , it builds fine. Trying to decide what to build this winter that would do well in contests.

I too have the platt FW and it flew the first 60Hr.s of flight time with a Super Tigre S-2500. At best it was saverly underpowered, I never got it over 65mph in level flight. Two years ago I Turned the engine into a Moki 1.8 and now it tools very nicely, but I have a over heating problem. I had this problem before with the Super Tiger and I used a Onboard mixture to control that. But I think I'll take the winter to install some ducting and use the mixture as a last resort.
It fly's great! Does tend to over heat. Bought a holman FW D9 afew years ago and can't weight to build it.

Platt had to install ducting in his because of ST 2500 overheating. . RCM had a short article on it. Many Moons have passed. Vailly has the fan installed (non-geared version) to force air though his cowl. He uses a G-62 as I remember

cooling
The problem of heat can be solved with a baffle that directs all incoming air towards the cylinder, provided the you have 3 times the outlet. The fan also helps but I think is not indispensable. Have photos of the Holman 190 set up at http://photos.yahoo.com/jgwarbirds

Those who know the Platt Fw190A know that the intake area aprox. Equals the exit area. With the S-2500 the problem was not as pronounced because the engine was shorter and the top of head was closer to the cool air stream from the inlet. The moki 1.8 however has the buisnes part of the head conciderably higher than the S-2500 which is why I think ducting is needed. Also the S-2500 would start to ping noticably to remind me to richen up the mixture the moki just runs. I've never done this before so do I need to duct the air out the exits or just to the head?

JG, I thought about cutting a cheeter hole underneath, infact I moved the Muffler out of the engine compartment 13years ago and that made a Big difference with the S-2500s over heating. But I plan to attack this one step at a time. The first being ducting, then mixture control (I think I'll try a cline pump, to remove the head presure difference as the feul burns, thats what used to get the S-2500), then cheeter holes. I'll just be happy when I can fly it with the cowl on again!
My Focke Wulf 190 A-4 powered buy a Moki 1.8 has Platt retracts, flaps and Weights 13# (almost 15# after adding the 27oz of feul.

Paladin: A hole is nor very efficient and it ruins the scale looks. If you look at photos # 5 in http://photos.yahoo.com/jgwarbirds you can see a sort'a open cowl flap under the cowl that works pretty good, never overheating even in hot & humid So FL summer.
I'm starting another Holman this time with a Moki 2.1 using the same technic.

JGrc,
That was my next question, (Foam or build up) Do you think the Platt wing will fit the Holman fiber glass fuse?, and did you added any carbon strips over the wing spars? and one last, what landing gear did you use in your awesome model?
Regards,
Loucel

Holman 190
Loucel:
I had to modify the root ribs (1 to 4) in order to exactly fit the Holman fuse since the foam wing is slightly thicker . I used Spring Air retracts but in my next 190 I'll use Shindin gear that has the scale geometry. Better yet Sierra Prec. has now scale gear for this bird.

JGrc, I love it! I still have the original Platt Kit (enough of the wood was so heavy that) I bought the wood and used the kit as a template. Bin looking at building another in the future but before I do I need to work out the cooling and that loos great. I see a glow hole in the cowl in other picktures, what size engine?
I've been looking at a Gasser for the next one which I could mount inverted, Focke Wulf A's beg for a Gasser. Also the Platt tail is about 2in shorter than it should be (according to the three views I have, They all very so much) so with that change the gasser looks even better.
My pressent Platt FW is built to the plans and with the engine upright. That has caused alot of problems with cooling, but Im going to think about that and how to make it work.
Loucel,
I hate to build scale planes with foam wings. the foam always seams to get into the way when I'm trying to do something different, or change my mind about how to dosomething half way through the installation. What I do is find some one in the clubs I belong to with a foam cutting bow. Layout where the ribs and main spar will go on the foam core. Then get togeather with the bow guy and cut up one of the cores. First we cut the spars, then cut the core at each rib location. When we are done I have my rib templates (the heat from the bow makes a nice surface to sand just alittle then trace from.
To All,
I've herd about alot of retracts for FW's that even have the locking brace, any body know of a web site were I might be able to get some info. on them?

Hi paladin,
check this out, I talked with Darrel, and he has the 1/5 scale size,www.sierraprecision.com/products.html
also check
http://www.unitracts.co.uk/index.htm...racts.htm</a>,
I'm going to build up the wing, just like JGrc did,
