1) [from post #81] When I redo the ailerons I am going to indent about an inch from the tips of each instead of having the whole length an aileron, but I am also going to lengthen the ailerons about two inches each at the center of the wing. That will add about an inch to each aileron, that should not affect the flying of my Skylark should it?
2)[from post #94] Before I open the roll who thinks I should exchange the small checkerboards for the bigger checkerboard design??? - will it really be more desirable in the air?
3) [from post #94] I have a question regarding the method you described . . . "Good use for a woodpecker as mentioned earlier in the thread(other than covering ), is to use it on two pieces of wood that will be glued flush (face to face) to each other. The little holes increase the surface area for the glue to attach to. Makes a much stronger bond for things like . . . " MY QUESTION - - - Would that process work for attaching the fin to the stabilizer, and attaching the stabilizer to the fuselage??? Or does that only work for pieces that are face to face like you mentioned??
P.S: I am still looking for suggestions for a good, reasonably priced 4-channel radio for this plane, any suggestions?
ANOTHER EDIT (QUESTIONS) - 1] What do you do with the inside of engine compartment? Do you leave it bare wood with just fuel-proofing, do you use covering over the fuel-proofing, or paint the compartment with comparible paint? 2] How do you do the wing hold-down dowels? Do you cover them with film or just paint them? PLEASE HELP WITH THESE AND THE PREVIOUS QUESTIONS. Thank you.
Here's my (opinions only) in response to your questions...
1) Yes, it will affect it, but you may or may not notice it. In general, with more control surface area towards the center of the wing, your plane will be more reponsive to roll at LOW speed. Having less aileron at the tips may in fact tame the roll rate at higher speeds, but again, probably not enough to notice.
2) CCRC was right on with his advice - "use what YOU can see easily". If little checkers work for you at a distance, use 'em. My general "guidelines" are suggestions only based on my experience as to what has worked, and what has not worked for me and what others have said over about 15 years of "experimenting". I find that larger shapes are much easier to pick out at a distance, even with 20/20 vision(I still have young eyes). 
3) Woodpecker... It might, but it's just one of those "extra" little tricks that sometimes helps, sometimes not. Not worth spending the money on the tool just for that one task. More important is to ensure you have a good solid glue joint in that area. I bought one a few years ago with the intention of using it for covering, but really don't use it all that much, and keep thinking up other uses for it so I don't feel that money was wasted. (BTW, It makes a REALLY good back-scratcher  )
As far as the inside of the fuel tank/engine compt, it depends on the plane. Normally, I just use thinned epoxy to fuelproof, mainly due to lazyness. If it's scale or something where details matter, then I paint as appropriate. Usually covering over fuel-proofing isn't needed, and won't stick very well without much effort anyway. Better to just paint if you want it to look nice.
I don't paint or cover the wing dowels, they get a very thin layer of epoxy to keep the fuel out, and they get touched up about once a season or so. You can paint them, but they won't be visible, and the paint will wear off after some flights, no matter how secure the wing is. I don't recommend trying to cover them - too much of a PITA. Some people just leave them bare, but that's taking a chance in the long run, especially if the leading edge of the wing is anywhere close to the exhaust.
Radio - Spend the money on a 6 channel(or more) computer radio!!! If you have any plans to stick with it, you(and your planes) will "grow" into it, and they have great features that help even from the get-go. You can buy one for not much more than a four channel, and the benifits(and convienience) vastly outweigh the cost. Most have multiple model setup memories, so as you aquire more planes, you can continue to use the same radio without having to buy a new transmitter everytime(you'll still need servos, receiver, etc).
I like the Futaba 6x and 7c series personally... but that's a whole other can of worms.  All of them work as designed. A good way to choose is to look at what others in your area are using, and get one that's at least similar(same brand). That way, you have others that can help you with the setup(if needed), and buddy-boxing is a lot easier(if needed).
Hope some of this helps, but in the end it's your choice on all of this stuff.

RE: Beginner's Corner - building of my new Goldberg S... - 
hope I can start putting more serious efforts into building soon. Got the rest of the formers into the fuselage though and epoxied. Test-fitted the bottom
