I got the vlx 4x4. I am thinking of upgrading to a castle creations motor. I ran those with good luck before I got out of the hobby. I am looking at getting either the 2400kv or the 3800kv. Which would be a better set up? Im not going to race and use it as a basher only. Can go with either 2s or 3s lipos. Only plan on going about 40 to 45 mph with this one. The next one I build for speed with be a slash with the mamba monster. I forgot how much of a money pit these can be but oh so worth it.
