hehe video….i might use the mini DV cams from school and upload it somehow……
Dave, i have almost finished your car, but i ran out of poly glue for the job (damn brother used it to fix ceiling console in his car) going to the LHS to get some tonight and this baby will be in the post 2morrow man. The servo has been tweaked and the bearings have been degreased for low mechanical resistance. Motor is done too. I am anticipating 36-42 km/h for yer car dave.
Specs:
6 cell 7.2v 750mAh NiMH soldered battery pack with deans 1/10 low loss connectors.
Tamiya 27t plasma dash motor with ball bearings, neodymium high power (Nd-Fe-B) magnets, copper magnet spacers (cheapest bang for buck mod) and massive heatsink with Deans 1/10 low loss connectors. The commutator has also been modded.
Internal 8×2 TURBO with heatsinks.
Lightened chassis (car weighs 240g, compared with stock 180g).
I am having a teeny bit of trouble with the ball diff at the moment, the monstrous torque being delivered through the GPM 13t Titanium pinion is enough to make a tight diff slip, which of course generates enough heat to make the aluminium diff plate thingies get quite hot.
The GPM titanium pinion is a necessity, as it does get hot, which would soften a plastic pinion and strip it.
Just when you though that wasn’t enough, i am going to rewind another TPD motor armature to 19t which should again double the power output. Bye bye batteries. This in theory should pass 100km/h.
I still have some work to do on this, i.e. perfecting gear mesh, re do the bearings and commutator, repair the diff.
I am hoping these few little fix ups will get me into the 80’s.
