Well, you can take the heatsink off, but the cooler the speedo is, the more efficient it will run. It does not weight that much anyway, 8gr maybe....
Anyway, the system worked great at the nordics, no problems what so ever!
Top speed was 64 kmh (geared 11.25), that is really fast on a small carpet track
I wonder how fast it would have gone outdoors..... too much snow right now
The feeling both on and off power was really smooth and the brakes felt perfect!
5.8V/4A BEC is really good, cant ask for more than that!!
