Well i called hpi and like always they are super cool about replacing stuff no hassle at all the only problem is is they do not have anymore of the tf45 tx and rx systems and she is sending me out a tf40 system which looks identical except for the yellow grip and what not but she said that this is a 2 channel i do not see where the tf40 has a 2 channel option the only other system thats a 2 channel is the tf20 what do you guys think was she just confused maybe?
