I also have both the T1d and T1s and have found the video is slightly better with the bluetooth completely off using the T!s. Plus there is less interference from other BT devices. The drawback is the wire. :)
Everything seems to be working as expected with my Note 9. Thanks again for all your hard work! REC feature purchased! It's amazing all the features you have brought out of the Tello! You rock!
You could try cleaning the VPS camera. Probably change the other 2 motors also. Check the 2 new motors for bent shafts after the ceiling hit. Ugggh, sorry ur having trouble,
