Good, some new members posting bots. Mr. Weedy's been the only one for too long. I'd suggest upgrading the weapon motor on Magmax (you have the weight to spare) which will enable you to give it a heavier shell.
Mr. Cuddles is a cool design, even though it's a SHW. Two 250 cm blades is nothing to shake a stick at. They seem a bit high though. You could give it smaller skis, so it would tip forward and the blades would hit more stuff.
