Great weapon on Viper!

- 26th August 2018

My son coupled this weapon with a viper kit. Very effective, took second place in his very first contest. See the blade working successfully here:

Powerful but unreliable

I've used this kit on two separate bots now, both of which were 2wd undercutters. The main issue is that the hub mounts directly to the motor shaft. While this does allow for a VERY powerful weapon, it results in the motor shaft becoming a critical weak point in the weapon system. I've sheared four motor shafts using this kit.
[FTR: The Viper and its add-ons are ripe for upgrading once you've broken them in! Some builders have replaced the stock motor shafts with hardened dowel pins to solve that particular issue.]

I had the opportunity to see at least two Viper kits using the spinner add-on at Robothon 2015 earlier this year. Both bots lost their spinners in both matches each of them competed in. The one that competed in the antweight rumble also lost its spinner there. The blade itself is quite good(as Cyclone from NERC has showcased), but the system as is admittedly has proven to be less than impressive. [FTR: Blade Hub is already being redesigned away from setscrew to clamp mount!]

I entered the robot with a spinner and got 1st place
