oh I forgot to add, I hoping I guessed the spring rate correctly, as you can see a 1" bar is enough to cause travel without lifting the chassis, but the whole thing takes my entire weight too when I stand on it (roughly 85kg's)
currently all the springs are the same type, I can adjust the pre-load by adding large diameter flat washers to bring the top of the spring closer to the bottom of the spring when the suspension is at rest, I also might need to change to a stiffer spring for front and rear bogies because they will take more stress from the track wrap On Jan 11, 9:50 pm, Modena <b...@holnet.net> wrote: > its a Tiger, and its now rolling!
