RE: new castle creation neu 1406 4 pole 35/50 motors
were did you get 1410 for the the sidewinder 3800 sct motor, mine is 53 mm long, the 1409 is 57 mm long so it would be strange if castle named them that way, the 1406 lists as 49mm long, so maybe the sw sct 3800 is a 1407 or 1408 LOL. Its so hard to tell a motors true power in the snowy crappy weather and sandy streets so my 3800 has only seen 2s and 8 cells so far.
LOL on the lead, some guys use stick on wheel weights for speed runs but we have found its much easier to just use a zip tie and some washers around the front bumper or shock tower, that way when your done you can just snip the tie. One local who is a proud redneck showed up with duct tape and quarters to hold the nose on e jato conversion down.
