Corsair, coming along

Corsair, coming along
Lot's of rough edges, but on this re-build I'm putting up with them. Full scale F4U wasn't exactly smooth either.
Needing a level surface to paint the firewall with epoxy, I used the furniture.
Lot's of plumbing there dictated by the vertical central mounted fuel tank that needed sealing. I filled it with balsa scraps and skimmed with filler and painted with epoxy. The whole thing will be over-sprayed with Insignia blue.
The local Hobby Town closed, my source for Aero gloss sanding sealer, and ebay stuff is $7.00 + $7.00 shipping for a 3.5 oz. bottle so I bought a qt. at Lowes for the same price. Water based it goes on nice and dries to a sandpaper finish in one hour. I will knock that down and apply a second coat then primer and cover coat. I painted a sacrificial piece of balsa to ensure compatibility with Lustrekote before painting the Corsair.
Straws come in handy.
I had the whole thing assembled only to tear it all down again.

PS - My son flew this Me-109 model this past weekend and smacked it in. No landing gear and the right wing caught and snapped on a diagonal mid-way, an easy almost invisible repair. Will fly again.
Eventually I will crash it and remove the radio (extremely light) and put in this Camel along with a Cox .010 or .020.

Re: Corsair, coming along
Bob, thanks for doing the sanding sealer test. So, sanding sealer is sanding sealer, soaks in and seals,as long as the finish coat is compatible. Good to know. I hope to get that far in a build someday!

Re: Corsair, coming along
So far, so good Rene. I don't know about being fuel proof or not, but it will be surfaced with Lustrekote.
First S/S coat soaked in well. I knocked it down with 400 grit after an hour, hit it with compressed air and added the second coat which dried nice and smooth, but I sanded it anyway. Primer and color goes on tomorrow, then Monokote on the wing.

Re: Corsair, coming along
Hi Bob,
What does the sanding sealer smell like? Any chance you can test compatibility between the Mineax SS and some old school dope?
I'd love to think we may have a cheaper alternative to dope SS.
Thanks,

Re: Corsair, coming along
Hey Bob. You're getting a LOT accomplished with building/finishing.. and it's really inspiring for a guy like me. I haven't done a whole lot of experimenting with finishes. There's so many variables as far as compatibility is concerned. I've NEVER been a "finish-man". If my finish was reasonably fuel-proof.. it was always "good enough". Since becoming a member "here".. I'm paying more attention to what people "like you".. are doing, to achieve good results.
I wasn't aware of the "Minwax" sanding-sealer product prior to your posting. I've used.. and still have some Aero-Gloss sanding-sealer. I always top-coated it with Aero-gloss dope.. and had decent lasting finishes. I also still have some Aero-Gloss fuel-proofer. I used to use that mostly around the engine-mount areas. Aero-Gloss always did well by me.. but now you're lucky to find it anywhere.. in a condition that's still "useable".. as you know...
Today's polyurethane-based products.. especially the "water-based" ones.. seem promising.. and much less "noxious" than the solvent-based finishes.
My CEF "Engine of the Month" entry was painted with Pactra "Furmula-U" rattle-can International-Orange twenty-five years ago.. and still has a tough-gloss finish that hasn't chipped/faded. It saw plenty of flights.. and was the first airplane that I was able to "stunt" with. I was particularly thrilled.. because it was my own 1/2A design.
The Pactra "Formula-U" was an early poly-urethane coating. I have two other rattle-can colors.. but God knows if they'd spray now.
I'm not opposed to "brushing-on" a compatible pigmented-color; top-coated with a tough fuel-proof poly clear-coat.. but I don't have much experience with that yet. My Rare Bear Speed-model was my first to receive a Top-Flight "Lustre-Coat" rattle-can finish. (TOPR7501-Crystal Clear) It was primed with rattle-can satin Rust-Oleum white.. (7791) The model hasn't had enough exposure to fuel/exhaust-oil wastes to tell. I've always been one to spray and wipe-down my models after an engine-run; with "cheap" (blue) w/s washer fluid. I pour it into a quart-size trigger-sprayer that I keep in my field-box. I keep a cloth rag that I throw over the engine.. before spraying the model. I like to keep a remnant-role of "Bounty" paper-towels with my field-gear, to wipe the model down. The w/s washer fluid cuts the oil.. and cleans nicely. Any metal parts should be wiped with an oil-dampened rag to retard oxidation while in storage.

This time of year I'm pretty stuffed up, but nothing out of the ordinary that I could detect. Can says, "use with adequate ventilation" but I considered my dining room was ventilated enough, and it's warm. It's water based. I applied it with a 1.5" cheap brush that bubbled, but going over it several times smoothed it right out. Dry time is an hour or less. I don't anticipate any interaction with the Lustrekote, but will spray that sacrificial piece of balsa first and wait five minutes or so before spraying the model.
Walmart bags, ya gotta love 'em.
Just received these five micro servos from China. $10.80 with free shipping. Price went up from $1.61 apiece. I've grown to love them. Tough with lots of torque and they are compatible with most of my radios. I'm thinking of using them in that Camel if Mark doesn't relinquish the Me-109. Just two channels, rudder and elevator and build it super light, tissue only.
Bob

Re: Corsair, coming along
Love your flaps plane roddie. You did a piece on it awhile ago, but I forget how you rigged the flaps and elevator????? I bought a spray can of Lustrekote at the local mom and pop that had been sitting for ages, got it home and it was dead on arrival. Hope you have better luck with that Pacta.
