Well, the cheap aloi shocks is currently second hand shocks. You can find in this forum, and other, some b4 shocks for less than 35€ (well, I'm a french, so euro's speaking

)
The good point is YOU choose the shocks you want. I wanted Losi shocks, I bough Losi shocks...
The bearing ball set is very cheap at rcbearings, as said by well advice battle-axe. In my position as euro's buyer, I do some good deal...
About the esc, I bough a ezrun 60A combo with a 8.5T motor at ebay. Very good price, very good esc and motor !
I'll do some competiton too, ad I'm not afraid about the Rat...
