I have ikon2 BT, and TBS Tracer Nano Receiver.
Questions:
1.) are these compatible with each other?
2.) If its possible how do I connect rx to ikon2 or wiring it?
3.) Would it be safe for helicopter up to 700 size's?
Yes, as with all TBS receivers also with the tracker nano, the output serial signal can be programmed with PPM or S.Bus protocols that are among the input protocols selectable in the six models of Brain2/iKon2 flight controllers.
As always, after selecting in the Brain2/iKon2 flight controller configuration software the communication protocol used by the receiver in panel 3 of the Wizard (PPM or S.Bus), the next panel 4 of the Wizard will show the correct connection scheme to be used with that protocol type.
Regarding the range of the receiver, the manufacturer of the receiver (TBS) should answer.
The RX manufacturer claims a range of 25Km, which is far greater than the maximum distance at which you can still see the orientation of a 700 or 800 class model.
However, it is always very important that the antennas are not shielded from the carbon frame of the model in any orientation.
