So the latest test for me will be my new [link=http://shop.rc-electronic.com/e-vendo.php?shop=k_emcotec_e&SessionId=&a=article&Pr odNr=A72005&t=11&c=764&p=764]Emcotec SPS[/link] (Safety Power Switch). Recently I had a tx shut off on the ground and the prop spin up while it was on the table so I decided to invest in some protection. I'm certain this gizmo has not seen a lot of use in the US, but I gather it is quite popular in Europe. So far the tests in my basement are very encouraging, seems to work like magic. The best part of all is that with my new redundant pwr system and Emcotec all in my E-Motion still weighs a mere 3729g (8 lbs 3.5 ozs)
