Radio uses its own battery.

excellent.

same amount of drain on the tx, compared to transmitting and regular usage?

i have a 2500mah battery in it, just wondering what to expect

thank you!

I’ve heard that you should take the crystal out of the radio. It won’t generate the signal and you will use much less battery power.

If you are using a JR radio you don’t need to take it out. JR uses the DSC jack, which causes it not to broadcast the signal.

Instructor: Don’t you know anything? Newbie: I don’t even suspect anything!

I use the 8u with reflex too. I have a 600 mah battery, I have removed the module. I get well over 5 hrs of tx use on a single charge, seems to use allot less power without the module in.

A nice thing happens to me. My 8103 Tx's battery was very bad due to a long time out of hobby and was planning to replace then I bought Reflex and it last 3 hours per charge in the beginning.

After some full charges and full discharges at low current drain is now lasting at least 10 hours with a single charge. Very good also in real life.

I thought that the Futaba buddy lead switches off the transmitting stage aswell - it certainly does on my FF8 - does it it not do it on the newer transmitters?

If you use the right cable the RF (radio part) will stay off, saving much (90% or so I think) energy. You can run really long on the same battery.

I wouldn't believe it if I hadn't just taken it off the charger.

I have a Futaba 9C with a 2500mah pack I made. I've been using Reflex since it arrived on Monday. The TX shows an accrued time of 5 hours and 38 minutes. I figured the batteries must be getting pretty low even though it showed 10.2 volts. I just took it off the Triton at .5 amp charge rate. It took a whopping 432 mah!. Obviously battery draw is very low. At least with the 9C that is. Not sure about other TX's.

I can get at least 12 hours of flight with my 8103 and stock 600mah. The internal circuitry doesn't drain almost any current, the module does it all!!

If the cable that plugs into the back of the radio turns the radio on by itself, then it should NOT be turning on the RF section of the radio. If you have to hit the radio's main power switch after plugging in the cable to power up the radio, then your RF section is on.

I can't speak for most brands, but many/most of the Futaba radios use a jumper type of setup for this. All the plug does is jumper two pins together when you plug it in and that provides power the necessary parts of the radio without hitting the RF section. I would bet that most other brands of radios use the same or very similar system.

Good point Roamer. I don't have to turn on my power switch. As soon as I plug in the cord it turns on.

I was also thinking back and I had also done a 10 minute hover in the living room with the Blade CP on the same battery charge. That was with a Spectra module in the TX. We all know how much power they suck up! I'm inclined to believe the 12 hours in Helibras post. It's obvious that the sim isn't going to lead to any TX battery failures that's for sure.

9c radio
On my 9c, the transmit light does not come on when I plug it in, so no need to remove the module. I'm sure that's how it wou;ld work with most transmitters, since it would be essentially in trainer mode.
