I think I'm going to get the Turnigy i6. It has everything I need and a little bit of telemetry. Thanks Everyone!
The supplied iA6 only provides RX battery telemetry. There is a
mod that lets you get the main battery voltage instead. Haven't done it. Just FYI.
The iA6B provides RX battery telemetry and supports the C series telemetry sensors. Really on the the
voltage sensor is useful since you can get main battery voltage with that. I doubt will care about temperature and RPM unless you have gas planes. The iA6B also supports PPM output which is good for reducing the wiring with multi-rotors.
You can only set a warning on the RX battery voltage which is a bit stupid but hey. Not sure doing the mod on the iA6 helps here because the warning range is limited.
The only problem I have come across with these radios apart from out of date firmware is that two people have reported broken gimbal springs. They did not ask FrySky for replacements so I can't tell how easy it is to get them. Replacement springs are not readily available elsewhere. I checked because I want to make the gimbals both self centering for robot use. It seems possible to make the springs from music wire which I may look into.
There are three optional cables...
They are hard to find on the HK site and people often seem confused over which is which so just letting you know where they are.
the
data cable for firmware updates. You may not need this immediately but the last two I bought had slightly old firmware with the model name bug so I recommend getting one. If you have an aduino you can use that instead but you would need to research it. I haven't tried updating yet.
the
simulator cable I discussed above.
the
trainer cable which you won't need unless you have a friend with an i6.
If you get a FlySky i6 it may come with a data cable depending where you get it You can get a Flysky i6 with an iA6B as a package from
Banggood. Seems the
data cable is not included. Banggood has the other cables too. I have not ordered from Banggood. Just FYI.
