My entire fleet is dji with the
evo 2 the only autel i have for personal flying. In our CE region, the autel beats occusync, this being the main reason i use it. I get an easy 2.5 mile without boosters or extra antennas which is wayyyy more than i need for standard ops. I havent done full EVLOS or BVLOS yet but plan to in the next few weeks so will be able to test full capability.
Only the cost and lack of support here in australia stop me from transition all of the birds.
I dont have any of your connection issues in a range of environments. I dont know why you are getting such poor performance. If i was in your shoes I certainly wouldnt have invested in the smart controller when you already knew you where getting such poor results. You should prob stick to DJI as it seems your opertaional environment is bester suited.
