Status: offline 		Hello everyone,

I figured I would start off this build thread for the new KMP/YT FW-190. This is my first KMP plane and I can see already it
will not be my last. This thing is built fantastic. There has been alot of people unhappy with the scale features of this plane and
I personally love it. There are some things that are off but that didnt stop me from buying it. I encourage every one to please post
their pictures and comments about their build with this plane on this thread. I would love to see other peoples builds and mods to
this plane with my own. I will try to keep this thread updated with my latest progress. Currently I have only managed to mock it up
to look at it overall and started with the wing by epoxying the control surfaces to the wing. I will wait to see how the KMP retracts look
if I am not happy when I receive them I will get some made by Sierra. I plan to put a gasser in this plane but have not decided
on which one yet. Plans also include a semi scale cockpit, scale guns, and relocate the tail gear to the scale location. I will post a side
view for those that are dying to see it.

Later,
Curt

Status: offline 		Okay,
I've started on the wings by epoxing the ailerons and flaps to the hinges and then to the wing sections,
and I have started installing some of the wing servos. Hopefully I will receive my retracts soon so I
can get the wing finished up and move onto the fuselage.
I'll get some pics posted soon of the wing progress as well as some close up shots of the rest of the plane.

Does anyone have any recommendations for a gasser in this plane. I would like it completely enclosed in the cowl.
The G-20 would fit but I dont think it has the power I'm looking for, and I'm afraid the G26 will stick out. Any other
suggestions for a gasser with electronic ignition and experiences would be appreciated.

The carb would a little but I am more worried about the top of the head, especially the spark plug.

Status: offline 		I have just started mine also. I wasn't happy with the location of the hinges (my flaps and ailerons were all about 2-3mm more outboard than they should have been) so have fixed that first.
Also, one of the gear doors did not fit the wing properly. I compared both wings and both doors and it seemed like it was the wing that was at fault. This was easily fixed with a little trimming with a knife.
My kit was delivered with the retracts, oleos and aluminum wheels. (bought in Australia from my LHS) They seem to be OK from my limited testing, but do seem to have a little more play than you would have from a premium set. This would be fairly easy to fix with a little machine work. The long legs magnify the situation, so you get about 3/8" of movement in each direction at the wheel.

Overall, I am really impressed with the quality of this kit. There are some really innovative techniques used in the construction, particularly the fiberglass backed up with a thin hard foam layer on the wings.

Mine will be powered by a Saito 170 radial, which I hope to have delivered in the next week or two.

Status: offline 		I too had a small problem with the ailerons, but the flaps went together great. I did finally get the ailerons
to fit Ok with the recommended throws.

The Saito 170 would be a great combo with this plane,
however I just cant handle the glow mess anymore
hence I want to try and get a gasser to fit.
But if you could get a scale Keleo exaust built for your engine
that would look sweet.

Status: offline 		I'm quite handy with a TIG welder (if I do say so myself ) so I will make my own exhaust for the Saito. I am trying to decide whether to exit the exhaust in the scale location (4 each side I think ???) or out the bottom of the cowl. I'm not so much worried about the mess the side exits will make, but I am concerned they would block off too much airflow from escaping the cowl. I am reluctant to progress too far with the build untill I get the engine. I plan to do the basics (fit control surfaces, retracts, join the wing etc...) then mount the engine and see how much I will need to move the radio gear around to get the C/G right.

One thing I am thinking of doing is removing some material from the wooden block on the fuse where the rudder hinges attach. It seems to be made of a fairly hard (and I assume heavy) piece of wood, and there would be no harm in removing some material there. This should help a little with getting the balance right.

What do you think about the hinges? mine has big ones for the ailerons, but smaller ones elswhere. I was thinking of stepping up the size of the small ones to some robarts (at least for rudder and elev.) My kit didn't come with the blocks shown in the instructions to support the hinges either.

I am also concerned about the friction of the fiberglass pushrods for the elevators. Might change it to solid carbon tubes, and get rid of the guide tubes. That reminds me, I got all the hardware for the rudder pull/pull, except the cable. Did yours come with the kit? Good excuse to upgrade to kevlar anyway I suppose....

Status: offline 		Your right about the exaust exiting 4 on each side. I would think you would be able to make it fit and have enough airflow.
There seem so be quite about of area for exiting air. But the size of your pipe would definately be a factor.

As far as the hinges go I aggree with you I think that the flaps ar OK but I am thinking of stepping up a size for the Rudder
and Elevator. My kit didnt come with the half moon blocks pictured either but in reality I dont know how I would make
them work anyway. So far all control surfaces have butted right up againts the wing or really close and I have my servos
hooked up to all wing surfaces and I have exactly the amount of throws the manual states, 20mm for ailerons and 30mm for flaps.
but with the hinges fully seated the way the wing is designed I cant get anymore out of them if I needed it though.

To the fiberglass pushrods I cant say for sure I havent got that far yet. But I do know that my kit did come with the cable.

I really would like to get my gear I would like to see if they are up to my satisfaction. If not I will most likely order a set from Sierra.
I need fairly sturdy landing gear from the area I fly off of.

After more thought I think I will incorporate the fuel tank as well with some sort of release mechanism I will have to find some actual pics
to see how it is done on the full scale version.

I really want to install a scale tailwheel as well but as of right now I havent figured out the best way to do that yet.
I'll try to post some pics of my progress soon. I have to many things going right now and only get to work on this plane about an hour a night.

Status: offline 		Hey dvs1, when you drilled the holes for the horns, was there enough meat there to attach them with self tapping screws? I know it's probably not a good idea, but I was thinking of not having the plate on the top surface of the wing for aesthetic reasons.
It would look much better without them, but obviously the result of the horn coming loose could look a lot worse.....

edit: it is only applicable to the ailerons, as the split flap hides the plate.
