Good pinionTo be used in 1:8 models. Very good.I'm so glad HK finally has a nice selection of M1 sized pinions. I'm using this 11T pinion on my Turnigy Trooper with a trackstar 4 pole 4250kv motor. It's a monster. I actually wish Hk had a smaller pinion than this one so I could gear it down a little more, as the speed is really excessive for an indoor track. Besides being too fast (is there such a thing?), it's a pretty standard gear at a fantastic price. No real complaints.
