An animated explanation of glider polar curves and how they relate to performance airspeeds.

Text-only version By Chris Fouquet cfouquet@pilotsguide.com { Wet Layup 'Glass Skins | Bagging Wood Veneer Skins | Bagging Supplies and Materials } The technique of vacuum bagging is used to construct foam core wings, either with a wet layup of fiberglass cloth and resin or to apply a wood veneer skin. Both practices use the same principal: enclose the wing in an airtight bag , then remove the ...

What do Thermals Look Like by Wayne Angevine This is an article that I posted to this list and rec.models.rc last June. It seems appropriate to post it again, since there are a lot of new people on the list and the topic seems to have come up again.

I don't pretend it's the only way, but it works for me - I don't pour molten lead directly into the ...

Performance Analysis of a Family of R/C Thermal Sailplanes by Blaine Beron-Rawdon Email: evdesign@cox.net Web: http://members.cox.net/evdesign Concept A theoretical study was made to evaluate the effect of minimum sink rate, span, and aspect ratio on the performance of a family of conventional radio controlled thermal sailplanes. The idea is to develop data which permits the designer to choose a ...
