I have the HL Abrams converted to USMC M1A1. I have the DBRC4 and Benedini. Between the 2 the Tamiya just seems of higher quality overall (torsion suspension, metal arms, bearings, excellent recoil, awesome gearbox etc.) The HL has some issues also. The DBRC4 is very picky when it comes to power. I have a new battery in it even with this it has started to shut itself down after a few minutes of running. If I battle the HL I will need to add the back up battery pack for the board. Up side is DBRC4 plays the Marine Corps Hymn LOL. Overall the Tamy is just better.
