Hey LDM.

Yeah mate, post away!!!!

suffice to say that i have already reinforced the gear area but there is always something more to learn or a new/better way of doing things. I have been trying to get in contact with Lenny at Shindin but he is not responding to my emails anymore??? anyone else having troubles? I would really like to get my hands on the gear if i can because as you can see the fuse is almost complete and all i will have left will be the wing to complete.

thanks

Dave

Thanks Moelders,

Starting out with an out of scale ARF ties your hands behind your back a fair bit when it comes to being totally correct scale wise but i'll try and get the best representation of an Fw-190 i can out of her.

Maybe one day i'll have enought time to build a Vally Fw or something like that which is mouch closer to scale to start with. in the mean time the CMpro will do

thanks

ORIGINAL: LDM

great job , I have found an old artical on foam wing/retracts install upgarde if your interested let me know .
Great stuff that may cure this planes history of weak retracts installation .

I've tried several methods. sure would like to hear about a better way before redoing mine again. Broke retracts out again this last Sat.[:@]

have cut out the ailerons and i've linished the aileron so all i have to do is cap the foam after i've added some "meat" for the hinges...

thanks

What are you planning on doing about the split flaps?

Hey Evil Merlin,

I plan to do scale spilt flaps as well...

I was almost about to sheet the top on the flap cutout before i cut the aileron off, but the flaps will be of a scale size and they are bigger than the kit sized ones, so i will mark out and remove the "flap area" material before i sheet the top of the wing.

The flap skins themself's will be about 3-4 layers of carbon fiber.

thanks

Default RE: CMPro 71" Fw-190 kitbash

time to attack the last major shape issue i'm going to do on this kit bash, the blisters on the nose cowl.

Pic #1: firstly is start out like i have always done and i wish the kit manufactures would have done, and that is with full sized three views of the blisters, they do stick out a fair way so what the main goal will be is to size them correctly in terms of the side view and position them in their correct location. at this stage,i also covered the cowl with clear packing tape. this allows me to work on the cowl and not damage it. I taped directly above the blister as the cowl is symetrical and this would give me the correct curve without the blister being in the way. a blank canvas if you will.

pic#2: i transfered the correct shape and location of the blister to the tape on the cowl with a permanent marker. for this i jut cut out the blister from the printed side view after placing some clear tape on it firstly, so that the cutout edges would let the marker "ride" along them

pic#3: This techinque i use is an extension of the platt idea, the pink stuff is 2 part automotive body filler, or bog. this is generously placed in the correct location.

Pic#4: after 3-5mins the bog begins to firm up and you can carve it with your hobby knife. this whole process is very time sensitive and you cannot leave it once you start! in another 3-5mins it will become too hard to carve, but hopefully you have roughly the right shape, and you can begin to sand it. the longer you leave it the hard the product becomes. it's still very sandable once fully cured, but why work harder than what you have to

Pic#5: the bog will pop off the tape, but a good property is that it sucks up some of the permanent marker you placed on the tape. perfect way to trasfer the correct shape to the bog!!! I then carve to almost the right outline and then sand the item till i'm happy. in this pic i have finished sanding the blister and have placed it back onto the cowl. this time i CA'd it to the tape.

Pic#6: another great feature of bog, it that you can always ad some more it it's not the right shape, over carved, etc... in this case, i add more to blend the blister back into the cowl.

Pic#7: this is where it's at right now. i coated the finished blister with a release agent then i also polish it with canubra wax as well, and then used about 10 or so layers of glass over the top.

The plan is to use this as a female mold, and i will lay up 2-3 layers of 3-6oz glass for the cowl, and end up with a nice, smooth external surface. it will be setup in such a way so that i can just cut the kit blisters off the cowl using the panel lines as guides and glue my new blisters into place!!! this also makes it really easy if i have to replace them in the future, or if i kitbash another one!!!!

thanks

Dave

Hey EM,

I was wondering the same thing for a while till it dawned on me

It's a bit of backwards and forwarding, but i got there in the end,

pic#1: this is the female mold all cured. you can just make out in the pic that i have attached some plastic strips to the top and bottom of the mold. this is so the when i lay the glass into the mold, i will end up with a "step" in the final piece which should in practice, align with the cutout in the cowl and give me a large area to glue to the cowl and so make a very strong joint. I took measurements for thse and it was a bit of a calculated guess.

pic#2: I removed the original blister along the exsisting panel lines.

Pic#3: this is the new blister. you can see where i have marked the lines were it should sit on the cowl. the front and rear sides will be cut to their final lengths, the top and bottom sides are the set which will be glued to the cowl.

Pic#4, 5, 6: these are the new blister attached. i just need to fill the joint line and they will be done. i will also add a small amount of glass to the front of the blister.

Pic#7: this is a pic i quickly drew to visualy show what i was trying to explain about the "step" in the new blisters top and bottom edges.

The only problem with the new blister is that now i have to make another of the other side

thanks

Dave

Default RE: CMPro 71" Fw-190 kitbash

Thanks guys!

I have just ordered the engine, i'm going with an SPE 40cc. i decided to go with this motor because i flew it with 20cc and thought it was a little marginal, so a 26cc gasser wouldn't be too much better, and the 40cc is only 200g heavier.

so a big engine to get this girl around. part two of wanting a bigger engine was that so i could spin a big three blade prop. and i am just about to pay for a zinger 18x8 3 blade prop. scale size for this model would be 22" prop, so mine will be little off, but hopefully still look good.

and i have found a drop tank, that is almost perfect size wise, but i haven't seen it yet and i'll post some pic's when i get it with my recommendations

On holidays for the next week or so, so no progress for now.

thanks

dave

I've been doing some more work on her but no pic's so far. i'll take some in the next few days.

But so far i have finished the right cowl blister, and am in the process of high fill primer coating it to see how it came out.

The SPE 40CC has arrived together with an 18x10 and a 20x8 prop to see which one works best. The zinger 18" 3 blade prop also arrive, but the clear coat on the blade is pretty bad and they supplied me with the "normal" blades as opposed to the new "pro" shape i was after. I also now have some materials to start looking at the cockpit, but at this stage i am more interested in just cutting it out and install what would otherwise be a pain to do once the canopy is down.

I have also, Thanks a whole heap to LDM got back in contact with Lenny at shindin, and it looks like the retrats are not to far away from being finished. he is waiting on a new drive belt for his lathe.

Thanks

Dave

The FW's look miles better with the 3 bladed prop. Great decision.

I'm going to have to call Lenny myself. I need a set of gear for three planes and wanna see if he is up on giving a try to make a couple of sets for my MiG-3's.

You won't be disappointed with his work.

Hey EM & LDM,

Yeah, the whole motive behinfd the oversized engine choice was the 3 blade prop.

I can't wait to see the gear from Lenny also.. Here is the pic he sent me of the top of the retract unit he has ready so far. He waiting on a new drive belt for his lathe to turn up so he can finish the gear!!!!

Thanks

Dave

Ok, here are the progress pic's.

Pic #1 is the glass curing in the mold for the right hand side cowl blister.

Pic #2-4 are the cowl bilsters finally finished.

Pic #5-6 is the new SPE 40cc engine, and the 18x10 and 20x8 props they recommened

Pic #7 is the Zinger 3 blade prop sitting ontop of the SPE, make the engine look small. it's an 18x8

Pic #8 is the prop infront of the cowl.... Pretty close to scale, only about 2-3" smaller.

Pic #9-10 this is the problem with the zinger 3 blade props, the center hub is masive!!![] and is over 1/4" bigger than the inside of the skyshark spinner i have for this model. I have been in discussion with the Aero engineer at work, and i think i'm going to make up some new hub plates whcih will reduce the center hub diameter by the required amount. so effectively i've wasted my money on the zinger, but at least now i have seen it and know how they make them.

thanks

Dave

Those look just like the ones he made for my Jack Devine 1/5th scale FW 190A8.

He does awesome work. With a little bit of styrene pipe you can make very scale looking struts with very little work.
