Restoring a Corsair for a friend.

Not sure, I know that's the one in the PT-19 and F-15. I haven't seen the Corsair yet.

Per this:

The fuel tank is part of the lower cowling, is that correct?

Travis, yes... if you watch this vid, (scroll to 03:00) you'll see what the tank/lower cowling looks like.

The one Bernie sells isn't the one. Maybe he can mount a 1/3 or 1/2 oz. wedge tank in there somehow? ...or just make a tank from a plastic 35mm film canister... looks like it would be close to the size... maybe a little too tall though. It only needs a supply fitting on the bottom and a vent on the top.

Non-pressure bladder. Stuff a balloon with a piece of brass tubing in and push fuel in. Super easy.

Many options on this one at least, if this is a runner and not a shelf queen. Wedge tanks and similar are easy too. Pressure bladders are not out either.

Or one of those round bottle type clunk tanks could probably fit in there and work well too. Either Sullivan or Dubro make the heat moldable plastic tanks like that in a 1 ounce size.

or... one could try a clear-plastic vending machine "toy capsule"... not sure how fuel proof they'd be... but since they pop apart into 2 pcs., it would be easy to install the feed/vent lines. Drill out top/bottom for short length silicone fuel tubing "seals"... and insert brass tubing through the seals for a no-leak/no glue compression fit.

Permanently assemble the 2 halves afterward with the appropriate glue; depending on the type of plastic. I believe the "clear" plastic is styrene; in which case, plastic model cement would work.

Even if eventually the tank didn't hold up to the fuel... the lines/seals could be pulled out and put in another capsule. Maybe a coat of clear polyurethane on the capsule halves... inside and out before assembly, would fuel-proof it?

Ok the fuel tank is all there except the bottom nipple is broke off. Any idea on how to fix it? I'd like to get it running for him.

Brass or aluminum tube pressed and glued in with epoxy or silicone.

Or screw a muffler pressure nipple into it.

I was thinking both ideas... I'll have to see what the hobby shop has...

I like that idea. I will try to remember it for later.

Any one have a red small rubber spinner and a LH spring/round cam (not hex)? These are the only parts he is missing so far.

See my want ad:

Thanks all for the suggestions.  I got it running last night.



I'm till looking for a red rubber spinner for it, if anyone has a spare.

Advise that you ask your friend if he intends to fly the plane and if he has any experience doing so.

It would be a shame to go to invest the time,work and expense of restoration only to have it crashed and quite possibly destroyed by an inexperiened CL pilot.

Better to learn to fly CL with a simple profile "slab wing profile" than and valueable Cox plastic Corsair and risk further damage.

BTW: Be sure any adhesives used are FUEL-PROOF.  

He says he has flown them when he was a kid. I told him he can do whatever he wants, I'm just the mechanic

Travis:

A "kid" and now are two different realities.

You might a least caution him per above. That's what friends are for.

SD

I know Dave  

Travis:

I can think of lots of things I did as "kid" that I can no longer do. Strange how that works isn't it?

SD

That would be the one Kim! Let me know how much I owe ya.

NICE JOB Travis!!!!  Thanks for posting the vid! Does that Corsair use a standard 5 x 3 prop?

Uses a Left Hand 3-blade prop, which turns in the opposite direction as standard.
