I wasn't happy with how the fin and rudder were turning out so I cut another top piece for the fin and shaped it. After some filler it will be nice.

I started the rudder today and should have it finished tomorrow. I'll upload pictures of the rudder when it is finished,

rwright142

Thanks for the lead! Bruce at Century Jet was on jury duty so he has not been available for awhile now. I'll check with shindin now.

For the most part, I'm much happier how the fin and rudder turned out this time. You can see a few 'mishaps' when cutting the lightening holes, but structural integrity is not affected.

The rudder needs some filler and weight up front in the balance tab but all is meshing together just fine.

I still need to add the fairings in the trailing edge of the fin too.

One thing I noticed is that the hinge point is inside the rudder brace. Was it a challenge to get the Robart hinge in there? Has anyone used more than 1 Robart hinge on the rudder?

I've also uploaded a picture of the tail wheel, I'm working on shaping the hook. I'll prime it and paint it 'steel'. Then I'll paint it with the alternating black/white stripes then weather the hook so it looks used.

rwright142

Forgot to mention it, but the tail wheel was made by Earl Aune, I'm just shaping the hook to make it look more scale-like.

Worked on horizontal stabilizer next. I discovered that there was a slight warp in the wood. So, after gluing it all together I placed weights on top of it. This reduced the bend to nearly unnoticeable but I will do it again when I glue the ribs onto the bottom side.

More work on the tail.

I want to start on the front of the fuselage next - the two large wing saddle pieces. I am having some difficulty understanding the bracing and connecting together of these 2 large parts. Can anyone share their pictures of this part of the build?

Thanks!

rwright142,

What is the wing span on that plane and how much do you think it will weigh when ready to fly? What engine are you putting in it?

Good luck,

Gibbs

It is the Brian Taylor 82" (1/6 scale). I have not yet decided on an engine so I cannot estimate the weight. The plans say approximately 14lbs but I have heard that Brian is an excellent designer/builder and that no one has achieved that weight (that I'm aware of). Most are aound 19-20lbs but I will likely be a little more than that because I am adding some 'stuff' that will add more weight.

Litho plate - what is this? On the plans it shows using it for gap seals, etc.

tubig

thin aluminum (approx. .005 thickness) used in printing process. from what i understand, the printing process hardens the aluminum making it a good source for panels, etc. usually the used pieces are free for the taking if you can find a local printer still using it.

rwright142

Thanks for the info. I will need to find a substitute. I would imagine some plastic sheeting would work too since the trim tabs won't be moving.

tubig

i've been using some aluminum flashing (gutter flashing) that i got from home depot. i think it's a little thicker than litho but it works fairly well. depending on what you're trying to simulate g-10, k&s soft aluminum, 1/64" ply and plastic sheet will work. for my gap seals, i use 1/64" ply. for trim tabs i use either the aluminum flashing or g-10 (easier to finish). fwiw.

rwright142

Nice tips! Thanks. I found some close-up detailed shots I took of an F4U-5 that shows the seals real nice so I now have a better idea of what to shoot for.

Anyone thinking of having folding wings? I have a friend that is working on a mechanism for me. I didn't want to go air so we are tinkering with a small electric motor (lightweight) using a lead screw. Depending on the outcome of the testing I'll let you all know more. If it works well enough I would like to use them for the retracts too. I know everyone and their uncle uses air, but I think it is worth looking into. I will need extra weight in the nose anyway so I could place batteries up there, etc. Plus the motors would be light-weight, controlled via circuits accessible from the belly, etc. Just some ideas I have been thinking about.

Merry Christmas!

Here are the wheels and the retracts I am getting. I think they look very scale-like.

I have made some progress on the wing folding. I'll try to get some video and upload soon.

I'll search, but does anyone know of the most common engine placed in this size Corsair?

those retract look perfect! where did you get them? does the air ram hit the spar?
i have built a wing folding setup as well using a quarter scale sail arm servo with a
servo slow from E.M.S/Jomar this is adjustable from normal speed to a 15 second transit
time, highly recommended.

They are being made by Earl Aune. The ones pictured were made by him. I do not have them yet so I cannot answer any other questions about mounting them, sorry.

Your wing fold sounds interesting. Can you provide more info? Email me if you can share drawings, ect.

sorry about the double post im a cyber idiot.i tried for 3 hours to post pics of my wing folding ......no luck even the email pics i sent you failed ....

power plant, i started with a Super Tiger 3250,it fits inside the cowel,sort of, but splurged on a Laser 300V twin instead

rwright142

I received the pictures you emailed, so keep them coming. If you still have problems uploading here let me know and I will do it for you.

yes go for it....... I feel I must warn you that Scale wing folding on a Corsair is an EXTENSIVE undertaking. you must be very patient and commited to take on this modification and get it right. its taken me 2 years (off and on) to get it right and there are still a lot of problems to work out. It took Earl Aune 7years to build the the finest corsair ive ever seen. So if you want to go to that level ,as i want to ,then by all means nesessary do it

rwright142

I am finding that out but like you I am willing to make the sacrifice.

rwright142

Pappy, your wing fold design is awesome! For those interested, here are some pictures he emailed me.

WOW

pappy 883 has a video of his wings folding here:

Pappy's folding wing is really impressive. Did he say how much extra weight the components added??

Keep up the good work on your build,
Pete

Hi, i havent weighed the components seperately but, heres where its at so far.
With engine (Laser 300v), all avionics (2 batteries),wing fold, retracts, wheels, cowl, pilot, it weighs in @17lbs.
Thats without any sheeting /fiberglass/paint,or scale details. I am hoping to be under 25lbs. balanced.
