Heliko this is an awesome thread. Thanks for being the guy to do this right and document it in a way that a newcomer like myself could also try to achieve these results. You might want to try the CNC Blade Grips. I like mine. Yes they do transfer the damage, but some of the crash energy is also absorbed and dampened in the process. What winds up breaking is the seesaw instead of the grips. This seems to happen after 2 or three shall we say "hard landings". Learning nose in on a failing stock battery can result in this.
