Better go read your post again Chris,ya told him to bend the hanger,but nothing about which way to bend it.
Try flipping the White motor magnet upside down,and grind the notch at the front of the shoe deeper,helps get the front end down.
If your running old stock G+ chassis's drill the pick-up shoe tit's with a small bit and insert a piece of .015" piano wire into the hole,helps stiffen up the old G+'s weak shoe tit's that are prone to breakage.
Run a Tyco rear axle,the smaller diameter Tyco axle helps free up the G abit,might be wise to drill the chassis for axle retention if you do this,as the smaller axle tends to pop outta the chassis easier.
Depending on track length,try running a 7/22 or 7/21 gear ratio.
Another trick i used to do was strip an old arm down till all that was left was the com and shaft,take the wire and arm blanks completely off,insert this into the brushes when your tweaking them,with everything off an old arm,you can actually see the brushes sitting on the com,and it helps when your tweaking them.
BTW,the modified endbells i listed above aren't really for a stock arm,more suited to the higher end Polymer and Neo magnet cars with custom arms.
If you don't have a guass meter,an old bolt and some washers makes an okay magnet matcher,just keep stacking washers till the magnet won't lift the bolt,and use this to compare and match your magnets.
I'm assuming you knew all this anyways Deane, :wave:
