Hi there,
The question is related to how I can check and charge a LiPo pack connected to the Digi Switch and not to the technical limitations of the device. I think and that the digi switch can cope with my servo configuration in terms of current load and supply. The electronic parts of the switch can cope to up to 12A load, however for optimal operation the manufacturer suggests 3A max load. May be during a snap it will reach 3-4 A load, for the rest of the pattern manouvers I doubt it. It is not a large 3D gas plane, but a pattern plane that will fly nice and smooth (hopefully

) with no big loads.
Just for your info it is not the first time I use a regulator which means that I know some basics, I have used SmartFly (Super Regulator and Single the yellow one), Jaccio and one custom made by a professional electrical engineer incorporating the Micrel linear regulator chipset. All of them are linear have been used succesfully and tested under stress with LiPo and LiIon packs from planes from 90 size to 2m F3A and 3D 50cc gas with no issues. I sincerely doubt that the Powerbox digi switch will not cope to the current loads of an F3A plane. Thanks for the info about the Fromeco switch and the 123 cells I don't know much about 123 to be honest.
Looking forward to other experiences with the Digit regulator/switch and setups.
