Magnuts!!...or Ground control to Major Tom
Posted: Wed Mar 29, 2017 10:35 amHi Gang, I don't often build magnet cars.....I don't like them, but, nor do I bash them.....lots of folks at the shop I help out at love them, and as you can imagine, magnet racers end up buying lots of parts.......so, they are good for business ;)
Anyway, I was contacted and asked to build a car for a class that had only one rule......you could only use 2 slot-it magnets!!......everything else is open ........ I can see the parts flying now!! :scared-eek:
So, as weight is the sworn enemy in magnet racing, and power is king, I had 2 objectives.....light/lots of grunt!!
I did build a car like this many moons ago,...it worked well, so with a few changes, I built its successor.
The complete chassis (as you see it) weighs 55gms, and it is powered by a much modified Pro Slot Euro Mk I motor,...... mods included, a drill blank motor shaft, upgraded comm, 80T x 30 wind, balanced, honed magnets, gold dust motor brushes etc. etc. and as a result should turn in the 50/60K range with lots of torque.
As you can see, the chassis incorporates a Slot-it pod......this pod was actually lighter than any brass/wire system I could create, so, as light is good, it was used.
It will be covered by a Lexan Ferrari 712 CanAm body, which will only add a gram or two at most.....the bare chassis has done a few test laps ......ridiculous!!! :laughing-rolling: :laughing-rolling:
It will now be sent to its new owner for atmosphere re-entry simulations :D
Cheers
Chris Walker
PS Since these shots were taken, the motor shafts have been trimmed, a center ground rear axle installed, and the front axle tube has had its top take off.....should save another gram!! ;)
