Status: offline 		I am kind of on my own here! What do you think of mounting the retract at this position. I could beef up the mount with plywood and dounble the former. Does the depth look right? What about position in relation to the plans? I could use the formers to hold the pull pull wires

Help!

Status: offline 		mistral, I used the Century Jet tailwheel, but the Robart will work just fine. Do you have any 3 view drawings of the Corsair? In the retracted position, the wheel should just about center F10B. You can make the cutout in F10B for the wheel. I actually removed F10B and made my lower section from F9B back out of fiberglass with tailwheel doors opened by the wheel. I'll get you some pics of my setup when I get the chance.

Status: offline 		Great I think the wheel comes down right over F10. I was working on the air cylinder placement lastPM and I think I am going to mount it on the bottom side of the cockpit deck. I was also thinking of mounting the air valve and servo there also. What do you think?

Status: offline 		I seriously thought about using a cylinder to actuate my tail wheel, to the point of buying the cylinder. I decided in the end to use a servo instead. I just thought that fewer air connections might limit the possibility of an air leak. I had my air valve and servo on the main servo tray, but moved it to the wing center, since I decided not to use the tail wheel cylinder. I was also going to mount the tail wheel cylinder @ the cockpit deck, and screw a 2-56 rod into the end of it to actuate the tail wheel. As for tail wheel steering, I just y'd a servo with the rudder servo, located it @ F8 and used 50 lb monofilament with clevises at the servo and tail wheel steering actuator. When the wheel is up, there is enough slack in the pull-pull cables to keep wheel from moving.

Status: offline 		No, I will be working on it for some time. I have the fuse almost skinned, have the tail feathers built and the wing is ready to skin. I checked out the retracts last night with the air system pumped up. I still have the engine to buy yet, as well as the glass, paint, etc. to finish it. I'm going to take my time and do panel lines, screws, weathering.

Status: offline 		Have you glassed a plane before. I can't decide between the .5 vs .75 oz cloth for the weight issue. I thinking about the super Tigre 90 for power.

Status: offline 		This will be my first time to glass. Aerospace Composite Products has .58 oz. fiberglass cloth. I think I will use that just for the weight issue. I plan on using an RCV 120SP for power and turn a big 3 blade prop.

Status: offline 		That is awsome work! You are going to blow me away. i too bought my glass from arespace. I plan to use their ez Lam expoxy. I have never glassed before either. I hope we do ok with glassing after all this work. I found a couple sites that may help.

Status: offline 		I sort of dread the glassing. I've read alot about it and the good thing about these builds is that it is hard to mess anything up so badly that it can't be fixed. I'm just going to take it slow and easy.

Status: offline 		Got the retract mounted. What do you think of placing the air cylinder of the former. Do you see a problem mounting the air valve on the cockpit deck? Do think a micro servo would work on the air valve?

Status: online 		Joe,
Glass work can be removed if its so bad you hate it. I bought a used corsair that was never finished that I later discovered had about 2 or 4 oz glass on the wings. I used a hot air gun (the one for covering) to heat up the glass and slowly pealed it off. Took a couple of hours. I know I lost several pounds doing that. It was a pain but I'm glad I did it. Something I'm going to try someday is polyurathan instead of resin. Water cleanup sure is appealing.

Status: offline 		mistral, your setup looks good to me. That's exactly where I was going to mount my tail wheel cylinder. You'll need 2 quick disconnects for the retracts and be sure to label them, LOL. I used a very old Futaba micro servo (physically much larger than today's micros but smaller than a standard). I think it has around 18 in-oz of torque. I also used a ball link on the servo arm just to make sure I didn't have any binding. Probably overkill.

Status: offline 		Hi all!! Really looks like Top-Flite's .60 Corsair is hard to die!
I'm building mine too, discovered this thread and... here I am to show my work progress and share some experiences.
At this time I have the wing completed, fuse almost finished (stab and fin still have to be glued): Tonight I will complete the installation of wing on the fuse and maybe start working on the belly-pan. This week-end I'll do some sanding... (just hate it!)

The corsair will be powered by a Saito FA125 side mounted, and my biggest headache was to install the tank at the same level fof the carb for reliable operation without pumps, glow-deivers or any other stuff that will add weight...
In addition I'm willing to shift weight as forward as I can since many .60 corsair owners refer that it is likely to be tail-heavy.
So my solution was a removable tank-tray so that I can locate it at the carb' level and access the throttle servo installed between formers F2 and F3 in case of need.

I posted this feature since all forums I surfed, very little info was given about this.

Hope this was useful

Marco
