    Default Traxxas blast upgrade

    Hey all. A friend of mine had a Traxxas blast he wants me to try and upgrade to make faster. I want to make it brushless and upgrade the driveshaft with the octura shaft ose sells. Thinking a 3200kv motor on 2s. Anyone ever upgrade a blast? I also wanna install turn fins and trim tabs to stabilize it for higher speeds. Any advice is appreciated.

    I had one long ago. 3500kv on 2S. I didn?t do turn fins or trim tabs, but should have. Wasn?t the most stable boat without that hardware with the extra speed.

    The plastic u-joint doesn?t hold up well to brushless. Consider a metal u-joint.

    Yeah, I was going to do a steel ujoint, OSE sells one but recommends no more than 20k rpm. I'm looking for a more sturdy one. Do you think the trim tabs and turn fins would help? What speed did you get out of the 3500kv motor? I don't want crazy speeds but somewhere around 30mph would be good.
