Are you talking about the Falcon 40 V2? If so, I hate to say it, but there is not much you can do to upgrade those. I would suggest looking into getting something like the mcpx bl or the Align 150 DFC if you are wanting more performance. ,
No it is the Raptor G2 V2 Exceed RC G2 Replacement Parts but if you look at the parts list the brushed motor sucks i already went through 3 of them and the Brushless has been out of stock for the last three years. so im wanting to get something different. i would also like to try and use a 3s 2200 mAh 30C lipo sice i have a bunch of them already
