Box 975, Olalla WA 98359All rights reservedIn the AirThe RCSoaringDigest Yahoo! group celebrated amilestone on August 21, shortly after the Septemberissue was put on-line, when an RCSD reader in Francebecame member number 1500. Membership in thisgroup is, of course, just a fraction of the total RCSDreadership. And yes, readership continues to grow.A recent issue of another popular RC aircraft magazinereviewed the Great Planes ElectriFly L-39 Albatross.This molded foam fun-scale model is rather small(the wingspan is just 25 inches) and is designed forelectric ducted fan. The $99 package includes theHyperFlow ducted fan and an Ammo brushless motor,but that doesn't mean you have to build and fly it withthose components installed. If any RCSD readersare contemplating a conversion of this cool lookingmodel from EDF to PSS, we'd very much appreciate anillustrated article on the process and the result.We're looking for someone to reestablish "The ToolRoom" as at least a somewhat regular column. Dremel'sMulti-Max Oscillating Tool System, scheduled tobe available in October, would make an excellent firstsubject. If reviewing newly introduced and/or lesscommon tools sounds like something you'd like to do, weencourage you to contact us.Time to build another sailplane!October 2008 3
