the lrp will %^$# on all of them engines...
put a buku power pipe with that lrp... youll be having wheelie issues its like a MMM in a 1/10 buggy...
also those hpi engines are expensive for what they are... LRP are like... the "Racing engine" for a monster truck. soo much power + speed too.

you'll love the lrp even more if its a savage with 3 speed.
