RE: SkyShark FW-190A8 Construction Thread
Hello Mike,
Really looking good -------May I suggest two things ?
Use a separate 'mini'servo for each aileron: considerably less slop than one servo via bellranks for both ailerons and many high quality reasonably priced 'mini'servos on the market.
The second,if I may,concerns your filling/filleting technique-BEFORE 'smoothing large areas, give the balsa a coat of what ever finish/surfacing product that you use(I use epoxy finishing resin.) after which you mix Dave Brown phenellic micro balloons,which are brown in color and are MUCH finer than regular micro balloons. Now mix the pre mixed epoxie adding mixing/adding mixing, till you have a very thick and nearly dry mixture then "work the filler into the desired area:stab/fin fillet and using a fair amount of pressure spread the filler using a Bondo type spreader,which you can also trim to approximate curvature of your fillet. This method works great and is reasonably light when mixed as I suggested and further the "pre-coat" of epoxy finishing resin belps insure you do not sand away the balsa surrounding the area to be filled,contoured or filleted.
Mike this was lengthly and I guess opinionated but I think this advise will serve a master modeler as your self and other builders well.

I suppose this thread is dead. I noticed that no exhaust vents where incorporated into the plane. I've devised a way to add these. I have posted a seperate thread with the illistrations. if anyone is interested.
