Ewwww don't go electric mate
. Personally if you want top notch and all the extras get the RC8B and sell the RC8. If your going to get the B then for sure get the Ghea 1.3mmx8 hole pistons (called 'Magic' as the holes are also drilled at a 45* angle). Another bit to invest in would be the Alloy Rear hubs from AE for adjustability and strength (though they are not totally needed). I personally wouldn't get the 1.1mmx10 hole pistons as the tracks over here (generally) are a little bit bumpy but might be worth a shout. Springs, either get the AE set or the HN/Jammin springs in Blue (for the front) and White (for the rear). Apart from than you're more than set to go!
