I'm sure this has been asked before , but I'm looking for help concerning the covering of solid flaps and , recessing of "barrel type" hinges and the order of Assembly .
Is it proper to cover them with silkspan (afraid of warps) ?
Should I notch the leading edge of the flap to reduce the gap between the trailing edge of the wing and the leading edge of the flap ?
I'm just looking for a trouble free operatin and a good looking flap/wing assembly .

Thanks 

Rob,
Notched leading edge of elevator half shown. 
Added Magnum Stab and Elev. with the notch again in the leading edge of the elevator. Make sure you bevel the leading edge of the elevator and the leading edge of the flaps. Then do a dry run with all the hinges in place and move the flap and/or the elevator up and down through it's travel to make sure all the hinges are working and that there is no hitting or binding thru the hinge line and you are getting the travel you wanted. After you paint or monocoat or whatever, epoxy the hinges in place doing one side at a time. I like to put all the hinges in the wing first and when it's dry I add the flaps. Same with the stab. The reason I do this is the wing gives you a nice straight edge to line all the hinges up to. Be carefull not to push the hinges all the way in until the barrel hits the wing as this will cause binding. Leave a small gap between the wing and the hinge barrel. Approx. 1/64. I put all the hinges in the stab first and line them up and when its dry I install the elevators. I like to rough up the hinges with sandpaper so the epoxy will get a good grip. I also put a small drop of 3 in 1 oil on the end of the hinge pin. Then I work the hinge back and forth and the capillary action of the oil will have it traveling the full length of the pin without making a mess on the outside. This helps prevent epoxy from getting in the hinge. I then push epoxy into the wing hinge slot and then I push the hinge into the wing about 80% of the way, then I use a Q-tip dampened in alcohol to wipe off the excess epoxy. After wiping one or two hinges  throw the Q-tip away and grab another so that you always have a clean one. I then push the hinge in to the location I want all the while making sure that all the hinges are even and square to the trailing edge. I know it sounds like a lot but once you get in the habit it goes pretty fast. I am not saying this is the only way, it's just the way I do it....Grins

Thanks Men !

Nice clear and concise 
It'll be a cakewalk (I hope) .

I'm kinda in agreement with Winfred...silkspan shrinks and puts the wood into compression....greatly adding strength.
"Black Death"...carbon matt, has little strength other than tensile....if you are prone to dropping objects onto your flaps, use it.....t sure is easy... But if you want to add some structural strength, silkspan is the way to go.
As to using nitrate...great, if you are a World Class builder like Bill....but if you build like I do, you are likely to sand through to the nitrate prior to finish....and that's un-good.

Thanks again !

More info to fill my "grey matter" 

I have always used silkspan but I find that I need to pay attention to trying to do both sides at the same time to prevent warps do to the shrinkage. I guess anytime you use dope it's always a possibility. How about you
