The fun of Tamiya WWII rc tanks is TBU battling: Underdog Sherman vs all the Axis tanks.
Abrams (plus M60/48), Challenger, Merkava, Leclerc and of course the existing Leopard vs T-90, T-80, T-64, T-72, T-62, T-55/54: Any 2 opposites, past the Leopard, would make a fine start for a new 1/16 scale rc main battle tank product line. Plus there would be the opportunity to model the MBTs in the colors of numerous nations.
Similar Abrams tank content was posted at "rc tank hq" back in January and the rumor is that the Abrams is a Tamiya management favorite. Over the last few years a Marine Corp. Abrams has been a star demonstration display at TamiyaCon and a real Tamiya favorite.
