Pretty much profile #3, I did change to Race Open (didn't touch timing) instead of Blinky, and cranked the BEC up. I've played with the throttle freq to no avail, and limited forward power to where I had trouble clearing jumps. Running a 14t pinion, which is much lower than anyone else. Ran a 16t but the VTX8 went into thermal in roughly 4 minutes. I usually saw about 185° on the esc, motor (HW 3656) close to 200°. Sorta weird as it would get that hot fairly early into a run, but never would get hotter. Unfortunately the heat has done it's damage to the motor, and it no longer would start from 0 rpm.
Either way, the VTX8 is now in my eBuggy and I'm really liking it. Much smoother than the RX8, and I have no temps problems. I need an esc and motor now for my sct, just looking at potentially trying something else. If a RX8 Gen2/pro4hd combo wasn't damn near $350.
have you tried another motor with the VTX8 on 2S? wondering if there is something specific to the motor that is causing heat issues you are seeing.
If you have a chance and a motor to try, bind one up in your e buggy since that is where the VTX8 is and set it up for 2S (love the profiles, makes it easy to switch). Give it a run and see how it goes. I seem to recall something about some motors causing issues.
I haven't had any heat issues with my HW 4000Kv combo at all with my VTX8. And since you are using it in E-buggy and it seems to work good there from the impression I am getting, I wonder if its the motor that caused the issue.
Outside of that, the HW combo you mentioned from what people are saying seems to work fine, though, i am not sure it will deliver the raw power you are used to with say an RX8 or VTX8. Probably along the lines of what my daughter sees with her current SP GT2.0 Pros I am thinking, maybe a bit more.
