After I iron the SLC, I brush two coats of dope and put the silkspan on the usual way, and spray two coats of dope and thinner 50/50. It melts the dope previously brushed on and the silkspan sticks to the SLC very nicely, and it takes much less dope to fill in the silkspan. On open Bays it's great because the dope doesn't leak to the inside, like when you are covering wings and the dope drips to the inside, it doesn't happen.
It's really good and adds no weight at all...Marcus
Well, it's not zero added weight, but it is minimal as long as you don't use TOO much.
Don't you love all the little detail work that goes into finishing a plane? You're doing great with it.
Glenn/Charles
Thanks a lot!
Done a fillet.
I use 30 min epoxi+microballoons. I tape around the wing-fuselage joint line and apply the epoxi mixture evenly.
Then, I soak my little finger with alcohol and run it over the joint, always from the TE to the LE, pressing the epoxi.
You get a smooth and even finish end wipe off all epoxi excess.
Marcus
Hi Marcus...good looking fillet there. You mentioned that you always go from the TE to the LE....whats your reasoning? Just curious. H^^
I've decided on white as base and red and blue marks to match the colors on the sticker.
Marcus,
What sticker? Did I miss something?
Charles
I guess by tomorrow I'll be done working on the wings.
Those fillets are almost done... S?P
Marcus
Looking GOOD Marcus. Keep it going and you should have a great flyer #^.
Later,

Marcus,......
I make mine with Polyester resin and micro-balloons. I've only used Epoxy two part glue. I gotta branch out. n~
I don't use tape as you have. I use my fingers. Different fingers give me a different radius. Wink, wink. :o
You're progressing!
Hey! How come you never get nasty replies like I do? H^^ LL~
Charles
The stab fillets... i'm way behind schedule with this ship... :P
Marcus
Thank you Charles
What I meant is that sometimes one can't do as much as it was planned.
I'm building 2 ships only... LL~
Work has been killing me, but it's never say die, right?
Today I'm going to have some free time and try to advance a little more both ships.
Marcus
It's OK. It needs a little work to be 100%, but it flies great!!Try to make the venturi a little longer. On some engines, the velocity of the incoming air bounces off when the crankshaft closes and lets fuel and air "backdraft". If you elongate the path, the momentum doesn't come back, it actually pressurizes the inlet at the crank when it opens again. Don't do smaller dia.!!!
I've got to decrease de venturi dia. 'cause it's slurping fuel and I can't get enough flight time.

A few adjustments in the engine cowl and that's it.
The pics requested...
Marcus
But FWIW, I had this friend who used to own a paint shop, and he was specialized in hi-end models, like mercedes benz and bmw's?
He Always said exactly what Robert says, finishing is sanding, the paint will only show what's underneath with colors...
Marcus
Robert is precisly correct, as is your friend,, However, just like practicing flying,, simply sanding (or practicing flying) does not insure success,, more QUALITY sanding ( or flying) makes the difference,,
so sand with a plan,, direction and discernement,, not willy - nilly,,
Mark,
Do willy and nilly always hang out together? Does nilly sometimes go it alone?
Mark,actually, Willy and Nilly are interrelated,( please note proper capitalization of the names,, these omissions tend to make Nilly rather upset,, Willy could care less, just give him beer and a lawn chair and he is good), much as Jekyll and Hyde,,

First coat of dope is on...
Marcus
So the Superfil has arrived! Congrats to Brodak for making it come so fast.
Have read the label and run a search here, anyway any tips I could use to get it nice?
I think making a template tool helps a lot, like the radius is smooth and even from the pics I've seen...
Let's see what I get.
Marcus
Derek thanks a lot!!
Ty, what you see is the adjustable rudder loose, not conected to the horn, that's why you see it with all that angle...
Now, I've put on 3 coats of raw dope, sanding each one, only the third was sanded with 600 and the plane seems sealed and ready for primer.
I ain't covering the balsa, so you guys think I should go with some more dope before primer?
I really don't want to screw up with this finishing...
Marcus
Remember not to back stroke with the brush as you put the carbon fiber down.
Ok.
I've got some 3 yards of CV.
And some silkspan too.
What would be better? I know I cannot cover the whole model with the CV I got, so, where should I cover with CV and where with silkspan? I figure the flaps should have the CV....
Any advice?
Thanks
Marcus
Tip of spinner to end of rudder is 47".Hmmm, if either of my cars was built around the Magnum, it would fit inside. I think it'll work. Thanks, Jim
I have put the Magnum in a Subaru Outback with the rear seats folded down. It takes up a lot of real estate, but there is still room for a flight box and other stuff. Just don't put anything heavy behind it, in case you have to stand on the brake at some point.
Wow Marcus, that really looks great!
Not sure why, but there is something about the look of the nose and spinner that make me think a WWII British paint job would really go well on this ship.
Thanks for sharing your build!
