I like it, but ima wait until they actually have mavic return ability. With the way this hobby advances Iâm sure that will be in a year or less.
I want to build a like a long range quad with a gimball that i can still fly some acro and fly fast as possible to do amazing filming of action sports subjects like freestyle motorcross and moto gp style racing, also some drifting. i was thinking a lumineer qav500 frame. Or the smallest a 7″ but i dont think it will carry a 3 axis true 360 pan gimball. I want to build this myself going at this from a freestyle building perspective. I just want the dji goodness so my girlfriend can fly it. Or the loiter for set up shots and time lapses and return to home and land would be awesome. but What fc and electronics (fc, esc,pdb,motors, props, gps unit, barometer, as much info input as possible to complete my goal. Would maybe kiss fc and a better gps unit like a pixihawk. Or a dji n3 or a3. I dont know if it will allow the extreme flying and the stupid geofencing. I want to go fast as possible and mildly fly acro to keep up with the action sports subjects. My phantom 4 will not keep up. I also want to fly far as possible and use 6 or 8s battery for max flight times. So how do i do long range fpv and long range control? What do you think of crossfire and open tx radio that will accept it like the jump t12
You are a gift to this hobby. I’m about to affiliate link my ass off.
my get gps command does not include ” gps_rescue_min_dth = 100″ How can I change DTH without this command? I am using BF 3.5 and 1/15/2019 firmware release. Perhaps the distance is now fixed? Other default modifications to gps worked fine.
My GPS arrived and I’m going to put another quad. But for me it seems safer not to use rescue-mode in failsafe, since the video signal may be lost before.
What data source is used by GPS_RESCUE_INITIAL_ALTITUDE, GAlt from GPS or Alt from barometer? Because both not showing the same value. Its very very different.
Hi Joshua, I bought two of these! thanx for the ti of swapping the rx and tx.. I am always ending up plugging rx to rx and tx to tx đ
Barwell, congratulations on your excellent work. All your videos are very well maintained, practical, objective and useful. About the material regarding GPS Rescue Mode, I had a question and would like to know if you can help me.
You say at some point that it should be configured for UBlox. I have a GPS that does not allow changing to UBlox and its default is NMEA. I’ve done some testing a while ago and remember that Betalfight can read the coordinates and display on the OSD even with the GPS with NMEA. I would like to know if to work with Rescue Mode I will need to have a GPS with UBlox. Thank you for your help.
Trying to set this up on a JB F4 UART 4 GPS and when I save reboot both ports get kicked out. Any Idea. Yes Im getting the flashing blue light indicator on the GPS. Your help would be greatly appreciated.
In betaflight 3.5.x I’m not seeing gps_rescue_min_dth in the cli?
Thank you again! đ Needed a refreshment course. haha
Just to let everyone know. I spend quite some time trying to figure out why BETA 3.5 did not have “gps_rescue_min_dth”. Come to find out JB told me that only BETA 4.0 has the cli option to change your DTH.
Planning to start testing gps rescue. My question is if there will be any problems taking over control or arming of the quad after fail safe and/or gps rescue activation with a switch, if my transmitter is set up to have a two stage arming switch. Thx
