ecx boost tranny issue
I went up to my local track last weekend to practice I ended up coming home with an ecx boost it was cheap and handled surprisingly good well needless to say I got bored of going slow and put mamba side winder3 in it on a 2s and now it's ridiculous but the tranny doesn't seem like its going to hold up and the driveshafts look weak anybody ever build one looking for some advice on how to beef it up
