I have had four brownouts recently. Recovered from three of them, the fourth resulted in a vertical dive straight into the ground with me fighting it all the way. Mind you, this is four using microservos in a multiplex gemini. They all scare the &^$%& out of me

Buy this plane............it only broke a strut and was flying the next day when the fourth and last brownout occurred.

The esc is a new 40a e-flite (V2), power 10 motor, 1500mah lipo. I am going to switch speed controllers back to the old one......an eflite40a (V2) also as it never had this problem and was the only thing that changed in the setup.

As i am getting into bigger electrics, a ubec seems reasonable and i have but one question. Does using a ubec disable the low voltage warning that is get from my esc. Ii use scorpion esc's in my bigger planes that pulse when they get low,and i love them. If it does, do they have their own low voltage warning?
