Like my 130 motor magnets, I can get any magnet any shape size, of neodymium...
however you should all know that the silver (its realy nickle) coated magnets inside the bit char G (the real ones) are ALREADY rare earth, neodymium... but I can still get a stronger grade if its required... and I can likely go a higher grade than my motor magnets cuz this is a non-heat build up location, so I dont need any heat tolerances at all.

The greyish black ones people are putting in are actualy WEAKER then neodymium high grade magnets can be... although I guess its possible its just a cheap ol ferrite with nickle plating too... but its pretty strong for a ferrite.
I could probly get one twice as strong... maybe even 3x as strong.. but unlikely, it would have to be bigger/thicker.. maybe I could get a THINNER magnet, cut some plastic away on that thing for a further tie rod stroke, and we can make a tighter steering mod
David (TinyRC) has already asked me to see if I can get some.. I have yet to send in the request for a quote... I will likely have to buy some were in the 10,000 range! so a Pre-Order, or david also helping with the initial fees might be required... although I could talk them down to a quarter of that if buyers dont mind paying more.....
so I now ask what are they worth to you if they are only 1.5 to 2x as strong as the ones in the car already?
If this was someting that required 3 or 4 per car... it would be more efficient to sell, but selling just 1 lil ol magnet to a buyer is kinda silly... I would do it in a flash if I could put a 10 magnet minimum per purchase... I guess they could make good toys

cuz they are VERY adictive finger toy.. while reading chat etc..

-- and this is a more universal shape (micro cylinder) so I could just bulk them off on ebay.... they DO sell good on ebay lots of Neodymium there, but not the exact right size yet... and along comes another idea, what if I got them a bit bigger diameter.. so we have to open the hole bigger, so its all that much stronger? naw.. probly too hard for newbies

although if your going in after the magnet your likely not a newbie

.
These magnets could probly be put on the motor to up the torque a bit too... might lose top end though...
Since they are Neo, I guess we can call this the "Neo Navigation Mod"
