which lipo?

[Serum]

that chassis hasn't got the kickup on the front bulks?!

If so; get the g-maxx...

for a 4S, you might as well consider using a 16160 instead of the 24160.

the maxamps seem to do okay, the FMA's are perfect, and so are the Orions, i heard Mike is racing them in 4S. they are a blast, their discharge is enormous.

I am making a lightweight maxx too, (allmost finished)

i use the g-maxx cf chassis. it's lighter than that xtremeracing.
