Top Flite Gold Editio F4U Corsair Build
 

I've been working on Top Flites Gold Edition F4U Corsair for several years and I'm getting there slowly but surely.I'm following RCGUY41 build and I ran into a question that I need an answer for,I tried messaging him but still no answer.I'm hoping someone here can help with the answer,I've attached a picture of what my question deals with.In the picture there's a red and a black plug(or connector)and I need to know what they are and where I can buy the.Any help that anyone can give me would be greatly appreciated.

They are air line connectors/couplers of some sort, though I do not recognize them. I assume those are the air lines for the retractable tail wheel unit. Robart Manufacturing, DreamWorks, and BVM Jets are just a few places that sell pneumatic retract accessories.

Replace the red and black with these instead. Use a red and black marker before separating them so that you can connect them back up quickly, especially if the lines are the same color. Those could be the fitting Century Jet had years back, but the only ones I know of, Sierra, and Robarts are the white ones.
