Designed as per the prevailing industry standards, it scores high on the aspect of utility. The quality material used in its construction makes it durable.

Review: Straightforward transaction. Please with the product.
Review: I had a FlyZone 2000mW (or just 2 Watts) and for some reason it just was getting too hot. Eventually the voltage regulator finally went out. This one has a good and a smaller fan but I've added another along with a larger metal heatsink and so far it is doing great. Just remember the more power the more heat will be generated so you have to compensate for that in some way.

## Questions & Answers

**Q: Is the audio input expecting a dc or ac signal from a microphone?**
A: everything on your audio video tx is DC. Most AV Tx operate on 12V. Most  FPV cameras  operate on 12V while a few operate on a range of voltages from 4.6V to 24V. The only thing on an RC system that produces AC  is the electronic speed controller, the output to the motor is AC

**Q: What is the green nc wire for?**
A: Dear James McCabe ,
Thanks for your kind asking.
Sorry for the late reply because we were on CNY long holiday.
The green nc wire for PPM function of the RC radio of the drone.
Hope thie can help you.

**Q: Where can I get a wiring harness for this transmitter?**
A: What do you mean?

The item includes several wires to meet the needs of the user.

The published images depict the meaning of each wire/color

**Q: What battery should I use with this? I want to get about ~35 minutes of use, only using a single camera.**
A: It pulls 1 amp at 12v, so that means you would want 3s 1000 mah,  in 35 mins you would pull about 600mah/60% of the change out the pack. Lipos do best with using 80 to 85% max of the packs compacity so that would be idea. If you ran a 6s 1000mah you could safely get 80 to 85 mins burning 85% of the pack.  Remember a 2w transmitter is gonna make mad amounts of heat and moving air is a must, this unit in a static environment at 2 watts/2000mw is gonna be a issue evenc with the built in fan. If you use will be in a static environment then you will deff want to place a fan blowing on it or you will no doubt have heat problems. I would simply run a 3s 2200mah pack and know that up to 100 minutes of so is absolutely gonna be safe on the pack.

Theres all kinds of warning to make sure antenna is installed before powering up. Well it didn't matter with this one. With antenna installed I powered unit on and the channel display showed (--) so I pressed the channel select button and display went blank. Then came the unmistakable burnt electronics smell. Giving the benefit of doubt I still tried it and sure enough no signal was being broadcast. I say look elsewhere for TX, hope this helps
