Last event :"FACTS" in Ghent wasn't good to Team RCC. Hannibalito wasn't happy, and did show it. First solid ali that did the job for 10 years Sheared off and new bolts lost their heads. After that de ESC went into safe mode, leaving us limping around as a dead, rheumatic snail. To finalise in a fight were weapon and drive failed in a distinct unspectacular way.
Perun, the one that always runs, lost the fuse, mechanicaly. And the fight after that, the link. To end up with 2 motor that replaced magnets with shards.
Kashei Besmertnye, the weapon stays a sore point. Needs a full rebuild.
Nebelwerfer 4 . A monster is born. 4mm grade 5 ti deforms undet the blows of the disk, the brushless drives are light, controlable and utterly powerfull. The disposable "ablative " hdpe armor took the worst blows. Untill the weaponmotor separated from the gearbox.
Some tweaking and 1 kg of improvements will show the true might of this Awakened One

We had anothern event. Utrecht was a repeat of FACTS.
Hannibalito 3 kept on being obnoxious, this time frying drives by the bucketload.
Probably sulking because Hannibalito 5 was trying to take the limelight.
Hannibalito5 , in sympathy and/or respect for the elder brother, fried the drive too....
Kashei, the weapon got some improvements, tested it to an inch of its life at home, seemed ok. First fight at the event, a gear that never failed, came lose... That is welded now. Next point of failure please.
Perun, charge battery, replace shredded wheels, ready. Untill the ESC failed mechanicaly.
Nebelwerfer 4... The show is on. This small monster is feared now in the Dutch/Belgian/German 6 kg class.

And that's what prompted a small rebuild.
The aluminium/titanium sandwich frame is replaced with a full welded titanium frame. The disk went from 800 grams of destruction to more than 1 kg.
And we went to far in the idea of an undercutter. Went undergroundcutter.
