elcome back! This is my favorite time of the year for flying—the days are cooler, with more pow- er for the engines and better lift under the wings, the sky seems to be cleaner and bluer and the winds calmer. What’s not to like? I hope you are having favorable weather and flying in your neck of the woods. I’ve been spending much more time in the office rather than flying, but have some good information for you this time around. I’ve posted photos of my Super Sniper
90XL. Now Rick Paquin has gotten his into the air and has found that it is a very stable airplane—even when trying to set up for a nice slow photo pass. His is also 10S 5000 mAh powered, and the weight savings of his

them both together! Rick’s Super Sniper in a photo pass (above right) at low speed during his verycomfortable maiden flight. Two 5S 5000 mAh Gens Ace packs power the airplane nicely even at their 6950-foot field elevation.
Gens Ace packs is significant over my packs. Me thinks, I might need to try some differ- ent batteries!
While on the topic of batteries, I was told about a “Real World Testing” thread on RC- Groups/The E Zone edf forum. It has brought back lots of memories of the series of tests that Ivan Munninghoff and I did eons ago. All I had available at the time were 2000 mAh Ni-Cd packs that were not really happy over 50 amps, got really hot and took forever to both cool, and charge. I could only meas- ure thrust (on a test stand) max amps and max volts.
My how things have changed! Joe Gia- mona (MSCGUY is his nom-de-plume in the forum) works with some sort of electrical/ servo/testing systems as his day job, so he
brings that knowledge and ability to both engineer the data collection and instrumen- tation, and also to record, tabulate and graph it as well. This thread has been roughly a year in its various forms of testing and there has been a huge amount of data presented, some at some ridiculously high current levels. The data has shown several brands to avoid, and several that have performed very well, and all at far less expense than several of the most highly regarded “name” brands. This is a very informed/informing thread (currently 57 pages long) that is very worth your time to read and can be found at: www.rcgroups. com/forums/
showthread.php?t=1767093. To me the most valuable part of the testing is that it is being performed in an airframe

PHOTO: ED VALLS
Seen at the Greater Southwest Jet Rally in September, Ed Valls’ 88-inch long A4 fuselage (at left) is massive! That is a six-inch diameter Byron fan, with room to spare. Ed built this airplane to test both a five- inch Dynamax and the six-inch Byron fans. Ready for its maiden flight (above), Ed’s A4 sits at the right ground angle for a Scooterwith a takeoff weight of 21.2 pounds. Constructed primarily of 9mm Depron foam and Dow’s blue insulation foam, this was a learning experience for Ed since he (like many of us) has primarily built with balsa, ply and fiberglass. With approximately 1260 square inches of wing area, the wing loading is about 39 ounces/square foot.
