RE: redudant rx setup problem
<span lang="EN">
Well let’s look at it mathematically. Lets say you draw 50 ma per flight and we have equal draw from both controllers (25 each). Keep in mind we are not drawing direct from the packs, but via the controller outputs. If each controller is indeed set at 6 volts, one half of the 50 ma need is pulled from each controller.</p>
So after one flight we have drawn 25 ma from each pack (theoretically). The 1,000 ma pack would (theoretically) now be showing 97.5% capacity remaining (975 / 1000). The 800 ma pack will be at 96.9% remaining (775 / 800). So in “Yepe”s case the numbers don’t add up if both controllers are set to a 6 volt output.</p>
The reality is this all just theory, I use dual Tech Aero controllers with dual TP 350 ma’s. Both controllers are set to 6 volts output. After several flights, I always put more back into one pack versus the other. We are dealing with $40 controllers, not $4,000.</p>
Silent-AV8T said it best. You should never, ever go by the percentage left on a volt meter. It just isn’t accurate enough. You should fly several flights and see how much you put back into each pack.</p>
The important issue here is we are not pulling direct from the packs. In this type of redundant set up (voltage the same), each pack will see equal current draw. The packs are not paralleled, rather the controllers.</p></span>
