Absolutely I would take the 1100kv motor. 35/47 gearing. The 800kv motor really shines on 10s and running it on 8s is not a enough for that KV. Plus you need at least a 40t pinion with the 47t spur. The 800kv is also harder on your batteries because of the necessity of a bigger pinion and your battery life is also less. And the 1100kv motor just gets to top speed faster than the 800kv motor. The problem is that the 1100kv Castle motor is hard to find. It took a while but I found one. You can also try the Max 5 and 1100kv 5687 motor with 35/47 gearing. Some of people say that motor runs hot on the K8S. I'm not sure about the O8S. I run the Max 5 and 1100kv 5687 motor with 25/35 gearing on my X-Maxx trucks and it works great for that set up.Can I ask, if you could do it again would you go with the same motor or the 800kv option. I'm still on the edge because I'm not familiar with either. Thanks
