I did some further investigating of my new score and found a Li-Po from my collection that fits perfectly.
I also found out that the servo included is a Hitec HS81MG.
Here's a pic under the lid......................................
My friend told me that he thought the included motor was brushless but it only has 2 wires so I suppose it's not.
The motor is a Team Orion Elite micro modified but I don't know anything else about the motor yet.
Edit: I found out it's coreless not brushless, that's an honest mistake.
My Tacon motor wont fit the hole pattern on the motor mount so I have to find myself another castle motor.
Or I could just put my Tacon 7800kv motor in my RC18 and use my 6800kv Tekin in this.
I mostly use my RC18T in large parking lots on a 3 cell Li-Po but since it's winter my temps might just stay low enough with the 7800kv anyways.
A kind member informed me that micro RS4 bodies will fit this car so I'll be shopping for a new body after Christmas.
