Wow thats a fast fielder. Awesome.
If I continue to get bad operation out of my mato lower under my Jumbo, I will transfer my hull over to a taigen chassis. I have way too much work into the jumbo to give it up over a problematic lower.
all I would have to do is build a new differential cover for a taigen.
let us know how the firefly performs. May you find many Tigers in your sights.
