i put the quickrun fusion pro in, easy peasy great motor, goes right in no problem, most of your list is the stuff in my list i have yet to order cause I'm lame lol
the rear link mounts have been my most broken part. like 3 of em maybe 4, but I'm rougher than normal on em.
i want a big ol reefs servo for it but $$$$
those hex extenders slip on easy peasy too. the front bumper kinda is a little long, it affects your entry angle so i cut mine down 10mm, but now you see the issue I'm havin with winch so oopsie lol
I'm not that guy that plugs his channel cause i didnt have one till i got into this hobby really, if you go to mine and type ecto ittl show you a LOT of videos on the ecto from a learners perspective and it climbing dumb stuff from its stock runs till literally yesterday lol.
this way i dont keep derailing your build bro
this was the old man pushing a tire lol i love it
