thank you for the reply. now to set aside the funds for this aircraft.

where can i get the manual for the h850 rtk. want to give it a good read before getting one.

6 more test flights were done on 8-27-22. on the first gen h520 with e90 camera. no issues with flights. older batteries were used 6 from 2017. lower flight times were had. but unit was stable.

just tested the new firmware on the h520e rtk. 7 back to back flights done with 2 payloads and no payload. with no payload at the location I was at the h520 rtk stayed connected and I had no control and or connection issues to the controller for the flight controls themselves. with pay loads...

here is some photos of the modification made to first gen h520 to see if the h920 motor blocks could be used to mount the h520e antennas. full battery test flights were done flight time was about the same when the first gen h520 had not been modified. the led covers has not been modified for the...

further flights done on 8-20 with the h520e rtk with the epoxy work done on the antennas still held up strong so thats one working method of repair. just tested second method of repair using the first gen h520 as a test bed. using h520e antennas mounted on h920 motor block that is held in place...

waited to basic testing was done with the first gen h520 modified with 2.4 ghz antennas attached on the arms. with new 2.4ghz antennas are those that are used on the h520e oem style using h920 motor blocks as the antenna mount points. there is a design flaw with the h520e 2.4 odfm antennas that...

just did some flights on 8-13 with the h520e rtk with diy repairs done to the antenna on the drone. repairs held up strong so far doing another set of flights at 31 mph as soon as the rain clears and the batteries charged fully. also when using a rtk base station the voltage usage goes up on the...

jb weld blue light activated glue used for antenna repair. reinforces the lens mount fine but needed to apply it to the antenna portion to the lens as well. after 1st 31.2mph flight the problem antenna came loose again. basically ended up coating the antenna to the lens with the jb weld. does...

just reinforced the rtk h520e antenna repair should hold up now. also reinforced the other side. did not apply it enough. started to come loose after first full 31 mph flight without payload.. while the h520e can handle 31.2mph flights the stress that the antennas endure can be problematic when...

so far vertigo drones is the only place I know where those repairs can be done. with luck I caught the rtk antenna issue in time to repair it myself. downside if any thing happens to that arm that whole arm must be replaced entirely. used jb weld light bonder on the antenna lens cover in three...

watch out for fine cracks in the antenna led lens cover to form over time.

as of recent those parts are not sold to the end user. I had to repair both my rtk and non rtk h520e with antenna lens coming off from the arms. had to send in both units to webster new york for repairs. for my case units were not in a crash. when unpacking the drones just bumped the antenna...

after heavy usage I have run across a potential defect at the antenna mounts on the arms. a hair line crack forms in the plastic led cover which will lead to the antenna to out right detach from arm of the aircraft if not delt with. symptoms are loose antenna that can be easy wiggled. also the...

got the h520e rtk backup in the air didi seven back to back flights non rtk mode. set the speed to max 31 mph and now can get total distance in air up to 51k feet from 35k feet. and about 20 min or a bit more per h520e oem battery and gifi 8000mah the h3 oems 19 to 19.5 min with lower distance...
