that is a duall plettenberg bigmaxx with 36 cells..
This is a movie of my savage with one of those motors on 16 cells.
It really is quick from 0.. not the lightest savage around though. I am going to do a new lighter 20 cell project.
about the plettenberg; The 7XL however is smoother, a tad stronger and much cheaper. (i sold my schulze/bigmaxx setup and bought a 7XL/9920)Welcome to the forum bytheway.
If you have got any question about converting the savage or any related question, feel free to ask!
