I would use it cause it should fit into any BEC fitted RX box/receiver. I use them all the time cause if you don't it might fry your ESC. I had a Duratrax ESC and I fried that one cause my RX did not have BEC. So since then I'm using RX receivers with built in BEC. Since the Tamiya stock ESC has no BEC so You do need a receiver with BEC. I only use 2.4 systems with my brushless set up since all my brushless ESC's have the built in BEC.
