...when i am using my simple aa batteries the module is getting little hotter , is it normal , using turngy 9x
Hi Vineet, I experienced the same thing with my E-sky. The AA batteries do make the Tx hot. If continued using for a longer period they might even damage the Tx. (which is what happened with my E-sky
)
I would suggest you to use the recommended batteries. Even though the rechargeable packs are costly, they are a good investment as they last long and you don't have to worry about your radio getting hot!
