    Default Flysky It4s with telemetry now in my UL-19

    I installed a new radio with telemetry. I couldn’t pass it up for $85new on eBay. That’s after a 15% discount through eBay. Normally about $100-125.

    I really wanted to be able to see the running temps and voltage under load. Now I can. I have not had a chance to try it yet.

    I zip tied the temp sensor to the motor and the voltage sensor leads could with be plugged directly in a balance connector on a battery to read cell voltage or tied into the total voltage. I installed them like an IV needle into the Y connector. They are sharp enough to pierce the wires insulation. I zip tied them in place and will seal the area with high temp black silicone/rtv.

    I really wish it had a brushless rpm sensor, the optical and magnetic sensors are pretty much worthless on a boat. Maybe that will be something available in the future.

    I might try to splice a cheap bl rpm sensor into the optical or magnetic module in place of the optical or magnet sensor. It’s three wires. Volts,ground, sensor rpm signal. I imagine it’s just a square wave pulse (on/off). I might get a reading on the transmitter, but I’m sure it won’t be accurate without having the abilities to modify the settings in the transmitter programming. Could still be a fun expiriment.

    I forgot to mention. It does,come with a communication bus module. But it really isn’t needed. You can daisy chain as many sensors you want in a line and plug it into the receiver.

    I’ll probably get a second temp sensor for the esc. I would for the batts, but I’m to lazy to mess with a temp sensor every time I have the batteries In and out.
