Center burner test.

Got it masked tonight.

[Aros]

LOVE the afterburner! Can't wait to add that when I get mine...

[Boots Whirlygig]

Looks great Steve! Questions:
What masking tape are you using?
What paint, rattle can or airbrush, if airbrush what gun for large coverage?
Are you doing an overall primer coat first, if so, what?

[RCjetdude]

Hey Boots, I am using green and yellow frog tape. Green on the canopy and LED lenses. Yellow on any painted surface applied after sticking it to my shirt first. Next I will be giving it a light sanding with some 220 grit sandpaper and then wiping it with denatured alcohol. After that I will wipe it down with a Tac Cloth. I will then spray it with light coats of Rust-Oleum white primer until the original SEA camo is covered. Finally, I will airbrush it with Model Master's acrylics that are thinned as necessary with Createx reducer. The airbrush I have is a Master SB80 and works very well.

I like the trigger airbrush style much better then my traditional one...I will have to pick one up.

Me too. I would love to have a GREX but those things are spensive!

Thanks for the info, I may order that airbrush. Is the Rustoleum white primer a “filling or sandable” primer? I know the finish on my Freewing F-16 and A-4 are beautiful and wouldn’t require filling and sanding, but the finish on my FMS P-40B is not so nice, and I wondered if a primer could help smooth out the foam cells prior to a repaint?

Primer going on...finally getting to paint this bird. After a light sanding with 220 grit and a good wipe down with denatured alcohol followed by a tac cloth this is where it's at. I should have everything primed by the end of the day.

Has anybody done a good calc of wing area of this plane? I’’’ve done a quick and dirty run at it, but think the result (of area) is too low. I’m coming up with 485 sq in area; my AUW is right at 4240 grams (149.5 oz). 485 / 144 = 3.37 sf; 149.5 / 3.37 = 44.4 oz/sf. Pretty hefty, and considering how well everybody feels they fly, Alpha and Crew picked a mighty good wing profile.

I’m no expert at determining lifting body area contributions, hence my skepticism regarding accuracy of my calcs. Anybody else take a run at it?

[Dirty Dee]

Manual calls out 26 dm^2 (403 sq in) but measuring in CAD gives me 573 sq. in.

Rather than calculating standard wing loading, try cubic wing loading. It gives a better representation, as larger planes can handle weight better.

For those who are not subscribed to my youtube channel, here are a few videos showing the flight characteristics. This jet is easy to fly and fairly forgiving.

Primer is done. Painting tomorrow.

Second video.

I know it will be a masterpiece!

Looks great Steve...Remind me, what is the livery choice?

Thanks, Dee. Wasn’t aware the manual had that info....when all else fails, then....:Cool:

Two more sorties today on the 8S JF90 Phantom. I'm really digging the power on this setup!

[Sky Wolf]

Steve, that is going to be one AWESOME machine. Can't wait to see her in action!!
