TimD, looking forward for a flight report. Thank you for created this thread.

TimD,
Thats really cool! What is your configuration for the sliding canopy? Are you using a linear servo?

Now looking to set up the gear doors with sequencing servos. I see the hardware in the manual photos for mounting the servos is not in the hardware bags.

I have the UMS 7yylinder 90cc radial in mine. I have a couple of bigger radials if I need to change it up. I added 2lbs of lead on standoffs as far forward as I could get it. I mounted an APS fuel pump to the inside of the firewall along with the batteries. Trying to keep the excess weight as far forward as possible so I would need less ballast. I will get a couple of pics of that next.

I use Hitec servos so here is what I came up with. Using the double arm , I cut one side off leaving one hole available. That hole goes to the short control rod. On the other side I went to the second hole out and connected the longer rod to it.

Thanks Tim!
it looks like you had more of the aluminum L mounts for the door servos.
i have kit #49 and it only had enough mounting hardware for the aileron and flap servos.
looks like I’ll have to make my own brackets.

What did you do for the canopy?

Scott

Mine did not come with them. I guess they figured we would come up with some or they did not calculate the hardware pack correctly. I made mine from 3/4" aluminum L-Stock. I cut 1/4" pieces. I bought the metal from Home depot years ago just for this purpose. Bob Violet made them out of a resin fiber for his models, that's where the concept came from. This is pretty much the same thing just a bit more work on our end.

Ok, after my final attempt at Balancing . I added another 20oz to the front totaling 4 1/4lbs of dead weight lead and it still needs more. I am speculating another 4lbs or so.
I plan to do an engine change and install a Moki 180 it needs the weight period!

I do like the plane and feel it is in comparison to the CARF at half the price.

TimD,
You have some great looking nomenclature added to your Corsair. Did you print it yourself, or did you find it from another supplier.
Scott

Hello,

Nice build thread!

I am currently assembling this plane with a Saito 90r3. Do you have any photos of how you attached the tail wheel steering? I can't seem to find any photos of how others have it set up.

Thanks,

Hi Tim, If you are planning to install a Moki 180 radial I have a set of exhaust pipes specially made for the Moki 180 ( see photos) Unfortunately I lost my Meister Corsair on a midair and as you can see one of the pipes has small bend. I am can sale them for $140.00 Custom Pipes Rc sales them for about $230.00.
If yo are interested you can email me at [email protected]

Has anyone been able to change the programer to Mode B? This is what I have tried: Press Setting to get to the Group I want to change. Press Setting to get to the right side of the group. light is blue at this point. Press Setting to change blue to green (Mode Set). Press the + button to change Mode. Light blinks. Then press Setting for 3 sec. to reset. Cycle gear a few times. But no change. Still in Mode A. Any ideas?

Same tiller as the rudder. Use a more inside hole to attach the wire as the tailwheel steering is more sensitive.

Try pressing the setting button until you get a blue A light then pess and hold settings for 3 secs to exit or just unplug the power. I have noticed that unless I cycle all the way through after a change in setting it won't hold the change .

What is the diameter of the main wheels?

Also

What is the extended strut length?

Thx in advance for any input

From strut base to axle centerline is 8"
The wheels are 5"

Did the OP ever fly this bird?

just completing my F4U. did get a flight on yours ?

so I'm curious what engine you went with and how much nose weight you had to add?

i used DLE 120 with small 6mm plugs. I made small blister on the cowl to cover plug caps. did not balance it yet

I’m just now getting back to working on mine . I had to take a break and get a new hip installed . Getting the FG 90 setup and the cowl fitted this weekend , I hope !

Cowl mounting to get the best cooling with an FG90R3 .

I used this method on my TopRC Zero also . It removes the restrictive cowl ring from the cowl air exit area .

Hi all,
will the moke 180 fits into the cowl nicely?

If I recall the Moki 180 radial has an outer diameter of about 250mm . The Corsair cowl inner diameter give or take a few for location is about 260mm so it will be a very close fit once you figure in thrust offset and cowl centering .

So no one has tried it? Will the rocker arms hit the cowl or it will be fit.

I know that in Germany there is one with a moki 180 see the german Forum http://www.rc-network.de/threads/top...rpunkt.782725/

I flew my new TopRCModel Corsair today. At 40lbs it actually flies great! Barely needed any trim. No aileron trim required and just 2 clicks of down. Take off was simple, barely needed rudder inputs. My CG is .5" forward from the manual and I might actually be nose heavy as I required a bit of elevator hold at slower speed and much more with full flaps. With that much elevator hold during landing, I basically did not have enough elevator to prevent it from bouncing so many times that the left wings center section broke. Anyways it is repairable and I am encourage to fix it since it flew extremely well.

Another note, I think this wing could be a little weak in the gull wing area for its weight, but I have to admit, it was a pretty bouncy landing and that is my fault entirely.

fw190 , Sorry to hear about your mishap on landing . I'm glad it's repairable . I have wondered a little about the center sections strength . I have seen mine flex slightly while handling it during assembly . I was at one time curious about whether the wing joiners could remain removable from the center section . Once I discovered the flex I decided it's best to go ahead and bond the joiners permanently to the center section.
I do hope the repairs go well and you get it back in the air soon .

From what I have looked at the only substantial spar is actually where the wing joiner is and near retract area. I am gonna take some pics

FW190,
I’m glad someone has flown this plane. Sorry about your landing. what engine did you go with and how much nose weight did you add?

Well here are the pictures

I flew it with a BME100, put around 4lbs on the nose. People admired how well it flew, however not my landing...

I also notice the flex when we flip it over after bolting the wings on. I would say no pilon racing with this thing.. just easy warbird flying.

I was expecting (hoping) to see a better internal structure . It looks like they took too much material out of the spars ,if you can call them spars , in an attempt to lighten an area that shouldn't be sacrificed for shedding weight . It also looks like the bonding agent doesn't hold well to the skin and pulled loose easily . I hope we all don't experience a similar failure

I agree on all what you mentioned. What scares me is the flex, if the skin was well glued to the structure you should have no flex, this wing is pretty thick.

Well repair is underway...

1 hour later this is what we have...

https://cimg0.ibsrv.net/gimg/www.rcu...9cf7ef5310.jpg

I thought it was kinda weak in this area of the gear cutout so I put some carbon fiber tow for added strength... Well it held up right!?!

The fuselage in perfect condition...


https://cimg4.ibsrv.net/gimg/www.rcu...28fe3ca9e6.jpg

I think I'm going to do some re-engineering and add some tow and some glass in as many areas as I can reasonably access

There is really no access to crucial areas unless you make some access. Here are some areas I think you can make without weakening the structure.
1 - Center top of the wing just below the fuselage, where my airlines come out can be cut out big enough so you can add the carbon tow to the main spar. In some Corsair plans they actually do not even sheet this area of the wing, but of course they have a good spar system.
2 - Cutting out a larger servo access panel for the inner flap servo access, I did not mount my flap servos to the hatches so I can easily do that.

These two areas will allow you to at least add strength to the spar.

BTW if you think that wing skin is any kind of support, it is not! But you probably already know.

I think I'll look into opening the oil coolers to get some access into the area that looks weakest from your photos. It looks like the coolers popped loose on yours so maybe it won't be that big a deal to do . I will probably saturate the spars with thinned Nitrate that will penetrate the wood and will add some plasticity and durability to it. I've used this method on many lightly built planes with great success . It adds tremedous tortional and shear strength without adding weight .

I would not cut out the front cooling intake its too much work to smooth it out again.

Anyways I have cut out the access area I needed
