I'm a little late to the game now adding the Arrma Typhon 6S BLX to my stable of cars, but I have put a new spin on the smaller Arrma 1/8th scale sibling. Here's a few items on a budget to add to your Typhon to make it look better and perform much better.
Here's a list of items I used for the BUdget Upgrade series:
Pro-Line Trifecta Wing:
/
Pro-Line Split Six Wheels:
/
Pro-Line Blockades M3:
/
Team Orion Neon8 System:
Futaba BLS371SV:
Airtronics MT-4:
