Hey now,
I fly mine with a Himax 2025 4200 (equivelent size/weight as park 400), CC 25 amp esc, APC 12-6 slofly prop, and 3s 1500 Kokams. Sometimes if I'm short a charged pack I'll use a TP2100 3s pack. Don't worry about it, just go ahead and fly. I often get told I've got too much weight on mine, or that the drive setup is overkill. Then they see it fly... and whine about how under powered their model is. Also you won't be happy with the little can motor they provide, even they say it won't do 3D with it.
