Ok guys I'm new to the RC car scene, was heavily involved many years ago then it dropped out, now after joining the military I'm back, I've purchased a Merv and I'm loving it, however, recently I picked up a few 3s lipos and a venom pro charger, car ran great, to great, a tire actually flew off because of the torque (the nut holding it on, not the tire from the rim) so after many days of waiting for parts (didn't have any other nuts), I thought I got the car up and running again, took it out for a run with just the stock NiMH's and am getting a horrible grinding sound, can't exactly pinpoint where on the chassis it's coming from, but the car will run, just don't want to destroy it. Also, I'm a basher/hobby racer, don't have any tracks around me so I just drive it on base. Looking to upgrade it so it has less of a Vance of breaking, any advice on upgrades to shocks etc? Also, going to be getting rid of the 3s's, might buy 2's but doubt they will make much difference over the stock NiMH in series.
Video of my issue, it's much more noticeable when it's outside and I can actually put power into it, also I'm not looking to replace whatever is broken with stock parts, as said before I wana upgrade it all.
