thanks for the comments.. I'll still get another heli, looks like the 450 cde, and i'll still use lipos but boy do i respect them now! I'll be takin it out of the heli to charge, and chargin it on concrete in the garage in future! smoke detector is a good idea but just in case, it cant set concrete on fire. I might not be able to fly too good but i'm expert on heli fires now
