Default RE: Pattern wings


ORIGINAL: speedracerntrixie

I have seen several discussions about wings as of late. Composite vs. Foam core, some failures of composite wings, top hinged Vs. center hinged, strength, weight, ect.... The last contest was at there were two composite wing failures over the weekend. Thank god no crashes resulted. This got me to thinking. I have been a scratch builder for 3 decades and have always cut my own foam cores and have a process for strait, strong and light wings. Seems to me that there may be a need for custom pattern wings. So my big question is: If you could order a set of wings with whatever airfoil, planform, aileron size, wing tube placement and were delivered where all you would have to do is final fitting, cover, glue in hinges and mount servo. Would this service be of use? Pictured is a wing off my own scratch built pattern plane. While they are a tad on the heavy side, there was no lightening done to the core, no hand selecting of wood. and a full size servo and heavy linkage. This wing could have easily have been built at 15 oz.



Speedracer,

I think guys are getting much lower weight than 15 ozs for their typical 400 square inch wing panel. Not unusual to be down around 12 ozs (foam w/ balsa sheeting, ultracoated) with servo RTF on electrics.

How large is the panel at 15 ozs?

Good luck with your service but beware. Hope it goes well for you
