1/8 buggy engine.

C hing,

U better think where will u play the buggy 1st, if in HK, I think better change to EP cos. more handy,less noise and less dirt.

but if u plan to race in China, u can check Alpha, Go tech, Argus for cheaper option.
OS, RB. Nova for top of the line.

engine price can be from 800 - 4xxx, hope can help!
