    Question Brushless Conversion Spring Question

    So, just about done completely converting my 3903 to the 3908 brushless version...got the wheelie bar, tires, hexes, servos, and of course the brushless system w/ mount.

    The only other difference I see between the two models are the springs.

    Are there any benefits switching the stock ones out for the progressive ones that come on the 3908? What would be the difference in handling, etc?

    Thanks in advance...

    big difference in handling. The stock "Red" springs are linear compression springs and the progressive are....welll....progressive, meaning the compression weight increases as the springs compress

    Let the arguements begin...........

    I see. Sounds like more of a preference thing. Not a clear cut winner...

    I have used both and I believe the res springs are just not up to the Maxx task - brushed or brushless. Lots of folks run aftermarket springs but I have noticed a definate difference in the Linear vs progressive

    I dont know about Traxxas spring rates. the general consensus is that no traxxas spring is good. Many people buy RC Raven dual rate (similar to progressive rate). Also, Associated springs are very popular.

    I went to my local Ace Hardeware, and found a huge selection of springs, I experimented and now run with 35wt oil, half ACE shocks and half stockers.
