Noticed an increase in range

In suburban areas I get about 30-40% more range than the stock. 5 stars are for Covert drones and great customer service. They are my source for Autel products.

Excellent Product, Excellent Service

If you're considering a modified controller, my experience with both the controller and Covert Drones would suggest that you should stop reading this and click the Complete Purchase button now.

Autel EVO II 6K Plus On The Go Bundle
Clear and bright

So far I like the smart controller it's size size is nice compared to a cell phone the screen is very bright and and you definitely need to use the strap lose the strap to hang around your neck while controlling it it's pretty heavy.

Pre Modified DJI Mavic Pro/Pro Platinum Remote for Titan Drones Antenna System
Over 3000 ft

Live in a heavy populated city and would maybe get 1200 or so feet before chopping video. Bought the alientech antenna and have pushed it to over 3200 ft. Thumbs up, works.

Top Notch Customer Service!

The turnaround time is amazing! The only thing better than the turnaround time, was the customer service!

The owner took time to text me, a couple different times to work out some kinks due to me being a novice.
