After the battery is then arrived, I found out quickly that he:
1. Easy in the "Revell Control Atomium" fits, even if it is slightly longer, it can be so far stuck in the cage that he does not disturb the balance.
2. That the battery summoned was delivered, and so the first own charging process was shortened
The first test flight I noticed no appreciable difference handling (except that I could do something to correct the forward flight by's Trimming), also it seemed to me as if I now had a minute or more flight time than the 300mAh-standard battery with the "Revell Control Atomium" came with.
Thus, this is 380 mAh battery 1. sinvoll for use with the "Revell Control Atomium" and holds 2. seemingly longer than the lighter by standard battery.
