Checking further (without taking a 'PRO apart to look at the fuse), I think the fuse is a FVT170F, which is rated at 1.7A. The radio takes up to 200mA, peaking rather higher when voice output is taking place, so for R9 to be OK, I would limit the current taken from the Futaba socket to around 1.2A....

The power connection on the Futaba port is basically battery voltage, but is switched via the power switch. However, the battery connects via a FUSE (FU1 type 170F), a current measuring resistor (R9 0.1ohm, 0.25W and a diode (D4 type SS34). The diode is rated at 3A. R9 measures the TOTAL current dr...

hi, Can I get the higher voltage and ampere by wiring modification on futaba port? I attached the 2.4Ghz 3000mW radio amplifier on my 9xr pro. the amplifier ask at least 5V /2A, support 5V~16V external power source. but I want to use futaba port of 9xr pro, as a power source of amplifier. how much v...
