So I just recently purchased one of these and am looking forward to getting it on the track. The only thing slowing me down so far was the lipo battery straps/holder was not in the kit. Currently i'm waiting on it so I can finish assembly. I'm going to be using a Spectrum dx2s with a Spectrum S6070 low profile servo. I will be using a mamba max pro with the castle creations 4 pole 4600kv motor. I'm curious where you guys would start gearing wise on a medium length asphalt course (using the stock 48 pitch spur)?
