I have been sitting in the background daring to mention the HM7000 chips. I have one fitted in a Dapol 08 that is usable by battery or track power. I brought a kit of a guy called Phil Downs via Ebay. They are very underrated chips it's just a shame they don't do a higher output option for them. I think this may have some bearing as to why Dapol are planning to fit 2 decoders to their Class 66 when it eventually arrives. It must be a lot cheaper for a start.Dare I mention Hornby HM7000? I'm interested to know if this is a viable option for wireless control. I'm tempted to try it, but my phone appears to be on the incompatibility list.
