After watching it's performance in Powers of Three, I wasn't too happy with Cold Front's performance. So I sort of updated it to fix a few of the flaws it had.
Besides the new skin, It now has a new drive system where it drives about as fast with 2WD powered by NPCF's opposed to 4WD with TWMR3's which gave me weight for the stronger armor to last a little longer in battle. I also fixed the Explosion acrobatics issue with a beater bar on the flipper. Only flaw I can't fix though is that it can't drive straight for some reason. I'm not really competitive when it comes to tournaments, but I felt it kind of needed the update. Did you like the old version though?
Also I made a similar designed HW:
I feel pretty good about how it turned out.
