Chunkloading transport drones and chunkloading express transport drones don't seem to load chunks and get stuck on the loaded chunk boundary. This was tested on the 1.7.10 HBM NTM version 1.0.27_X5193, although I remember having issues with them loading chunks since they were added. This was also tested with no other mods installed, including Optifine. I haven't tested this on an HBM-only server.
