I love having telemetry in all of my airplanes. The capacity consumed feature of this receiver is just really good. It’s like having a gas gauge,and the accuracy is really good too. The only gripe I really have is that this receiver uses the power box option on your spektrum transmitter. This means you have to listen to 2 call outs of capacity consume and voltage. This is an issue with the spektrum transmitter software, because the power box option used 2 batteries instead of one and you are unable to shut this option off. It’s not a big issue, just a small little gripe. If you wanted to add telemetry just using the spektrum receiver’s, you would pay a heck of a lot more
