I have an EzUHF that I'm going to be using on my Spektrum DX8. Since my DX8 only has a 2S 4000mAh 7.4V battery, and the EzUHF requires 9-12V, can I use a step-up power regulator to supply 12V??? I'm thinking about using one because I do not want to have to add another lipo to the back of the Tx. It's already heavy enough with the EzUHF. Looking at this step-up regulator.... http://www.readymaderc.com/store/ind...roducts_id=316
Would this be a good idea?????
