I recently did some indoor flying with an indoor rev and was thinking now about buying an indoor but, I have a Zen and did not try it indoors. Would the Zen work for me indoors? Would I have to remove the bridle from it? Why is there no bridle on the indoor revs? It is my understanding that years past before I was a flyer most would fly 1.5's indoors that they modified a bit to make lighter. That was all there was.This may have came up before but i cant seem to find it......thanks
