When subscribing to or renewing the paper version of the Ampeer, please make the check payable to Ken Myers. We do not have a DBA for the Ampeer or EFO. Thanks, Ken The article is an excerpted from my article "One Way of Selecting a Brushless Outrunner Electric Motor for a Radio Controlled (RC or R/C) Sport Plane or Sport Scale Plane Using ANR26650M1 (A123 Systems NanophospateTM lithium ion) 2300mAh Cells" which can be found at M1-outrunners.htm. Use that link to read the article, as it will always be the most current iteration of the information. The February EFO Meeting The February meeting of the EFO had been postponed a week because of the poor weather conditions on February 7. The postponed meeting was absolutely excellent. Thank you Mr. Bill Brown for your great hospitality and wonderful ambiance for a meeting room. His basement is full of current and "historical" projects, and it has to be seen to be believed! Jim Young started off the official part of the meeting by asking if anyone had any idea how he could mount the specially made retracts (by Robart) into the nacelle of his DH-88 Comet. This 300 sq.in., great flying twin can be seen at www.tnjmodels.rchomepage.com/tnjdh88.php.

Unfortunately, we didn't come up with any possible working solution for him, but we did admire the retracts! They will be a very nice addition to this model and make getting it into the air a bit easier and safer. Ken Myers shared the changes he made from the original Fred Reese "Swallow" to create his own version, which he has named "Son of Swallow". Ken will give complete details about this model in an upcoming Ampeer. The basics are: Wing Area: ~415 sq.in.
Ken pointing out some techniques used on the SOS Jim Maughan shared his beta build of the Radical RC Das Mini Low Stick. You can check out some of Jim's build notes in this thread on RC Groups. Jim's still thinking about finishing up with some stars and bars and possibly some invasion stripes and a canopy.

Roger Wilfong had his 2-Cutie. It is a modified version of the SR Batteries Cutie, which now has been converted to a biplane. The top wing was shortened by a bay per panel and the lower wing by 2 bays per panel. He's planning on doing the initial flight with a 120 watt in power system, and will up the power if he feels that it is necessary. For even more on this mod, see RogerŐs thread on RC Groups at www.rcgroups.com/forums/showthread.php?t=809371. Bill Brown shared several of his current projects. He has a Hangar 9 Sopwith Camel 60 ARF in the finishing stages. He has the ANR26650M1 A123 Systems, Inc. cells nestled around the AXI 4120/xx motor. The reason for the xx after the motor, is he, like Ken, has a motor that does not match any known specifications for this series of motor. 
Cells as far forward as possible
Bill has a version of a wing type model that first flew with a glow motor and galloping ghost type RC system. He had tried to convert it to electric power several years ago using a brushed motor and Ni-Cads. It flew, but not "correctly." It would fly very well up wind, but it would become almost uncontrollable when going downwind. He asked for ideas about how to make it "behave" while flying. He knew that it would fly, as he had flown using glow power. Several ideas were given, so Bill should once again have this very interesting model flying.
It was an excellent night with a lot of sharing of ideas and suggestions and a lot of "plane" talk. Dang, these meetings are fun! Thanks a ton Bill for hosting!
The March meeting will be held at Rick Sawicki's house on Thursday, March 13. Please note the date. It is the second Thursday of the month, NOT the first! The meeting will start at 7:30, so hope to see you there. This is the same place that we've met many times for the previous two years. You can find Rick's address and phone number in the header of this issue. Hope to see you there with your latest projects!
