MBX5 T brushless

thanks,
no video at the time, will do soon.
The battery tray is there, just a little cleaning on the truck and i'll post the pics
Yes the 1521 is great but is a little hard with my lipo: about 120°F with a 5000mah evo25 after about 15min, what do tou think about it? is it to much?
I just bought 2 dewalt packs to see if a123's handles it better...
