Well I got to run some more laps today with this buggy man it's so much fun to drive and super easy compared to my last buggy.
To the people having loose rear end are you maybe trying to over power the track? I dropped my current limiter down to 50% today and it was planted and hooked up. I still had plenty of punch to make the big jumps but it was so controlled.
As bottoming out I am running the stock springs with 45f and 40r and it feels fine to me.
I prefer the feel of softer springs and harder oil as it allows the buggy to find traction with a bit of roll.
Also run times improved as well got 20 mins out of a 5300mah
