Thanks for the replies and answers guys.........firstly.......the glitch u speak of POSSIBLE could have been cause by sum power wires that were pretty near by when i was hovering......i'm testing today in a more isolated area to troubleshoot.....i'm goin to turn the gain down until i seem the tail wag disappear......i've actually been on this site for alittle while now and have tried to learn as much as possible before i actually got the Blade CX2.....i made sure to get a bunch of spare parts and i've fused the motors to try and protect the 4 in 1 as much as possible.....will be doin the cooling mod as soon as I get sum more batteries and will be doin more sustained flights......the issue regarding the status light turning from green to red....it happens once i go full or almost full throttle and stays that way until i back off the throttle.....jus wanted to kno if this happened to anyone else and wasn't a defect in my 4 in 1.
