Hi zac dady, I received a Tango 40 for Christmas and like you I am thinking about going electric with my first 40 sized plane. Have you flown yours yet? Was the E-flite Power 46 BL Outrunner sufficient for this size plane? Did you use the recommended 13x6.5E prop? I agree, the batteries cost way too much, but what can you do. I have a couple of 40-52 sized gassers laying around that I could use, but want to try the bigger sized electrics. The thread on RC Universe has me concerned that it may not be that great of a plane though. Several negative comments about how it flies. How well did yours fly --- gem5tigers
