Just got off the phone with horizon and here is the low down
First up is the AR 12000. A 12 ch rx that will take dual battery set up through two servo type sockets . Much like the Jr 1221. Difference is its about half the price. Full retail is set at £179.99
Next up is the 12001 which is a 12ch version of the AR 9100. It has the dual battery inputs through heavy duty leads and connectors. Soft switch and high amp rated structure.
This one is set to retail at £199.99
I placed my orders there and then and was told delivery will be April some time.
Hope this helps. ( it certainly does for me )
