Wow, thanks Monkey.
Some good information in there:
"I noticed the ball races were fairly well packed with grease, so I put all the cars ball races in some motor spray for de-greasing and oiled them with some trinity royal oil. This frees things up greatly and would help the standard motor propel the car."
Haha, and the motor revs at 38,000 rpm.
The upgraded motor sounds great:
"With the car rebuilt and Tekin Mini Rage installed and working nicely, I wanted to test the cars speed and see how it handled the Tekin system. I took the Frog to work and gave it a quick blast around the office with the 5.4kv motor and 13t pinion, the slipper worked hard and the car was super quick – I certainly couldn’t apply full throttle. I then took it to the carpark (parking lot for those of you in the USA) around the back of the offices.
Awesome is all I could say about the speed, the motor felt under geared with the 13t pinion (smallest metal one I had) but speed was still very good.
Rather than just change pinions, since this was just a quick test, I stuck in the 8kv motor and 15t pinion. On the first few seconds of driving this I thought it was no faster than the 5.4 motor- until I realized the tyres were just spinning!
When I managed to control my throttle finger to set off under control (this is REALLY powerful) the top speed was nothing short of awesome, I’d guess similar to my B4 with a 9-10 turn in it or that's how it felt, it was wild."
