As you can see the test yesterday (dipoles - unboosted) was disappointing.
So for tests sake, I took it to the same flight path this morning, weather was the same, A little less cloudy. But on the DBS controller I hooked the boosters back up. I got a good signal for most of the way out, bars dropping a couple times due to antenna aiming. Took it out to 27,000+ feet turned around at 50%. On the return home my signal wasn't as great,The Wi-Fi signal would go up and down every two seconds causing the screen to display "safe to fly GPS" & then "no signal" it switched back-and-forth between the two so fast that I never lost satellite view and was able to fly that way but my camera view was in and out every other second.this happened for most of the way back which would've been concerning had I not had my satellite view to fly with. I was also getting a "strong interference"message during that time! So I don't know if the strong interference was causing the signal loss or if it was the dipoles. Either way big difference between the 12,000 foot unboosted & and the 27,000 foot boosted flight. By the way my signal was strong I only turned around because of the battery percentage. But I've done that flightpath several times on this windy days, stock bird with boosted DBS, and got 30+ thousand feet with a lot less signal issues. Eventually I may have to just go back to stock bird with boosted DBSView attachment 49894 View attachment 49895
Were you flying it with your battery mod? I think in your 40'K flight you had more battery left (56%) than in this one, you got to 27' and had 50%.
Do you use batt mod on every flight?
