Hi Adrian. James uses the DX3 (steerwheel spektrum) but it has similar features to the AR receiver regarding failsafes, although really easy to drive with. We sell the BR receivers, and ordering a batch of them shortly. If anyone else is interested in a DX6 or receiver then please let me know as they take between 2-3weeks to order in. Your batteries should be pretty much sorted now youve used them for a weekend. As ewan said, charge them slow at home, around 0.3/0.4A.
