Hello, I am interested in a cowl as well if one is available. I have 2 new corsairs and the first is about finished​​​​​​. The other will be glassed and painted. Never hurts to have spare parts.

Moments from tragedy:

I went to an event on Saturday and as usual when I'm setting up the Hog to fly I get a lot of questions.

I put her together, flipped it over on to the gear and after a while pushed it out to the flight line to fly.

As I was hitting the radial with a starter the wing dropped right out of the saddle. I thought because I was talking I forgot the damn wing bolts, but they weren't in my tx box and after 8 of us walking around in the grass for a while I disconnected the wing and put it on a stand and flipped it over to find the wing bolts screwed into the blind nuts. The bolt heads had completely pulled through the wing! HOLY CRAP!!

If they would have held just enough to get the engine started and get into the air the results would have been catastrophic or worse. I don't fly at the flight line so doubtful it would have hit anything but the dirt but you never know.

The bolts have a narrow head to clear the tube into the wing, I would normally prefer flange bolts or big washers. My buddy is cracking it open from the area behind the wing but covered by the fuse and installing a G10 plate.

I gave everything a pretty good inspection when I did the radio change over to Powerbox a few weeks back but I guess a more detailed inspection was in order

Hi
Is the Hangar 9 Corsair 60cc still being manufactured as I thought it had been discontinued
Thx

It's long been discontinued and any thoughts of it coming back in its current form are nil because the factory that made it closed.

Hi All, I have a corsair that I have flown 4 times. It has a Saito 84 in it but i am thinking of taking everything out and sell it (or i can leave the servos - all JR- as I mainly fly turbines and honestly, don't like it. Is anyone interested in the airframe and landing gears only? I had a minor ground damage to the leading edge of outer left wing that has been perfectly fixed.

Thanks, Behzad

I know this is an old thread, but I'll ask anyway. I bought one of these, Hanger 9 60cc size Corsair, from the family of a modeler who died. The plane looks in good shape and appears to have flow very little if at all. It has a DLE 85 and air retracts. I assume Robart. I'm going through the plane and making a few changes to suit myself such as re-plumbing the gas tank and converting to a three line system. What size three blade prop would work? Also, does any one have the control throws. I can't find a copy of the manual. I have read that the throws recommended in the manual work well.

RBean

Never mind. I found the manual on line. It has the control throws.

RBean

I've been working on the Corsair. First was sorting out the wiring. Finally got that done, radio installed and all servos checked out. Then the retracts. These are Robart air retracts. Would not hold pressure. spent a day and a half chasing leaks. Found filler valve leaking. Replaced valve and valve core. Then found control valve leaking. Not the O rings. Leaking where the nipple is pressed in. Replaced the control valve. Then found leaks at main gear air cylinder nipples. The leaks at a T fitting in center section. Held air for several hours and still operated gear. Fortunately there were no leaks at the air bottles. That is good because the previous owner installed two smaller bottles that are not easily removed. The fuel tank had a bunch of black sludge in it. Had to use carb clearer to get out. I figure the carb is contaminated and will probably require engine removal and carb over haul. But thought I would try. Fuel up and hit with electric starter. It fired, so pumping fuel. After several more attempts it started and ran. I was shocked. Carb linkage needs adjusting. Adjusted linkage. Ran again. The DLE 85 idles at 1,580 rpm. Top is 6,200 rpm with 25x10 two blade Xoar prop. I would like to install a three blade prop for scale looks. I think a 22x10 is recommended. Any information on this?

I purchased a 23x10 3 blade from zy hobbies for somewhere around $40 for my dj72cc engine. I’m at 5000+ feet though. An 85cc could most likely do bigger.

bob violet models sells some lubricant for air retracts that keep the o-rings operable. I rebuild my systems every 5 years unless I have an issue.

it sounds like you got the fuel system cleaned out and going. A carb kit is $5 from China on eBay. It takes about an hour to do. Several good videos on YouTube if you need it. If your not able to tune the engine start there. Best of luck. My build is turning into a marathon with everything in life right now, but getting close.

I flew the Corsair today. It went well. Take off ok. Just needed a little aileron trim to right. Went will. Never got over 75% power. Gear down ok, flaps down. Had a bouncy landing but no damage. Then noticed canopy had departed. Look for canopy but could find it. Didn't know it came off until after landed. It had a crack in it that had been taped over, maybe it came apart. Don't know if this was the cause or not. Can't find a replacement. Any information on a canopy that will fit?

RBean

I flew the Corsair again. This time, takeoff was ok, gear up ok, then on downwind the engine just quit. Was able to get the gear down and do a 180 to landing on the runway. Then, back in the pit the engine starts with a few flips and runs good? I'm new to the DLE 85. Looked up instruction and calls for 1/8" id fuel line. Also was using a Walbro 125-527 in tank filter. I discover it is only rated to 30cc. Maybe engine was fuel starved when I went near full power??? Got larger fuel line, also large size Pro Flex for inside the tank, larger Walbro 532 filter. Just barely fit into tank. Received new canopy. Masked and painted and installed. I think every thing is ready. Go to the field, engine hard to start, won't idle. Reduce to mid throttle and engine slows and dies. I think the low end needle and/or jets are stopped up. Finally removed engine and carb. Took carb apart and found brown slug or gum. Not much, but does not take much to stop up small passage ways. Carb kit on order.

After taking engine off, I weighted the lead. 4.5 lbs.

Found out from one who knew the now deceased owner that plane had not run for 10 years. So does not surprise me the carb needs cleaning and a carb kit. Also installed larger tank, had to reposition the throttle servo to make room for the tank and re-route the choke lever. In my two brief flights I find the plane flies good.

Sounds great, what did you end up doing for the canopy? And where is your CG? I got one ready to fly but we flew it a couple of years ago and I did not keep great records on the CG range.

RBean

I found the canopy on ebay for 60cc sized Corsair. If you need, I can look up the seller. I received the carb kit and got it installed today. It was what I thought, the low speed/idle jet was stopped up. I hope to do a test run at home tomorrow and maybe fly it Wednesday, weather permitting. The cg is right in the middle of what the instructions call for, but I don't remember the numbers.

RBean

I test ran the engine yesterday. Once the needles were reset it ran fine with 25/10/2 prop. Idle about 1,600 rpm and top about 6,250 rpm with good transition. Other events intervened so no flight yet.

RBean

I finally got to fly the Corsair again today. No problems and uneventful. Take off good. Gear up ok. Only it was running rich. Loop, roll, cuban eight. Slowed and flaps down. It was rolling a little to the right I think with flaps down. Landed ok on the mains. The needles are hard to get to with the shock mount for the engine, but leaned some. Refueled, aired up gear. Take off ok. Engine still rich but better. Loops, Rolls, reverse cuban 8s. Leaned out on the up line so getting close to proper needle setting. So leaned out slightly more on high needle. Getting too hot and humid so headed in to AC. Here are some pictures. Prior owner did it in Navy Reserve scheme for Miami Naval Reserve Air Base. Here are some pictures at the field.

Looks great! We need to fly ours together someitme!

RBean

Flying together would be great. Flew the Corsair today. Hot and humid. First flight ok. Engine still rich but better. Manuvors ok, landing ok except still rolling left some with flaps down. Adjusted flaps. 1/8th more turn lean on high needle. Take off good, engine running better almost there. Manuvors ok, then when time to land gear would not come down. Finally landed in high grass. Damage were the bomb pylons and broken prop. Cause was ring nut mounting air valve had come off. Servo was not moving valve. Reinstalled and used locktite. Of course nut couldn't come off before retracting gear only afterwards. Refueled, added air to gear. Replaced prop with 22/10/3. Started ok, take off ok.Engine running good. Manuvors ok. There was not enough loss of thrust with the 3 blade to notice. Here are pictures at home with the three blade prop.

RBean

I thought I had this plane sorted out. Several non-evenful flights. Checked gear system for leaks. Aired up and left over night. Held air over night so no leaks. At field, assembled plane, fueled up, aired up gear. Started ok. Take off was good, gear up ok, manuvors ok. Then gear would not come down. Finally landed in grass near runway. Broke my three blade prop but no other damage. Gear system had no air. Finally figured it out. It had a digital servo running the air control valve. It was chattering. Anytime the valve is not at the end, it is leaking air. Replaced with analog servo. Several flights since with no problem. I have never seen this before.

Not sure if I posted this before, the canopy details really help sell it

RBean

Matt, the detail is something else. Are there pictures of the rest of the interior?

mr_matt

My Feedback: (10)

I still got to finish but they never seem to get finished

The consoles pop in and out on magnets, easier to see here.

I am very pleased with the mirrors, it really adds something.

That's just SICK! Wow!

spitfire66

That looks amazing. Are the panels something you 3d printed or something available for purchase? The magnet idea is brilliant! Nice job painting as well.

mr_matt

My Feedback: (10)

No I make it all myself, I usually use the factory drawings. Everything except the front windscreen is removable with magnets. I was worried that the vibration and such would wreck the parts or shake all the magnets loose but it works great.



I use factory drawings as canvases to design the parts. I have access to virtually all of the drawings. Straight from the design office in the 1940s!

There was enough detail to design most of the canopy parts with this one assembly drawing, but if I needed to I could pull up any of the detailed drawings.
