Savox 1256TG servo
65C Stick Pack LiPo
Ideas, suggestions etc. I have always had good success with the MMP in my Ve8 running the T8 1900KV in sensored mode so that is why I was looking at one for this truck. Is the RX8 that much better? The RX8 just seems hard to find in stock.
Thanks in advance as I am sure I will have plenty more questions.
I personally think the MMP is the best bang for the buck but the RX8 is a very good ESC as well. Pick your poison.
I am extremely happy with the Pro4 4K in this truck. The 4600 is overkill in this lighter 4x.
You do not need the torque of the Savox 1256. The 1258 has plenty of torque, is faster, and draws less power. If you decide to go with the MMP, you need to be selective on your servo choice. The internal BEC cannot keep up with high torque servos such as the 1256. I run torque limiting in the MMP to try and keep the internal BEC happy. Even the guys that run the RX8 I know run current limiting.
Any good lipo at 50C or better will be just fine. If you are racing you may want to think about inline saddle lipos. Truck is more balanced and less likely to traction roll.
