RE: Futaba 12 FG Dummies Guide
Since there already exists the Futaba 12FG FAQ and Hobbico's Futaba 12FG owner forum (Futaba Flyers' Club), it would seem to me that the 12FG owner forum may be a natural place to home any organized compendium of practical information for the 12FG (and 8FG) that might be linked from all the many scattered sources plus practical tutorials.
The problem with a printed book is the 12FG/8FG will change gradually as Futaba releases software updates. However, if any particular well-known technical author wanted to publish an electronic version of the "Futaba 12FG User Guide" not unlike the printed "Futaba 9C User Guide", I certainly would purchase a subscription to the web version.
Just my thoughts...
