Hello All,

Today I received my Nitro Hammer that I bought on ebay...so siked. Anyway i have a few question's ...Okay here it goes:

1). What kind of performance pipe can I upgrade the exhaust to and would it have to tune the engine ?
2). The prop has a small crack in it...would this cause some performance issues and also what kind is the best to upgrade?
3) Lastly...Is 30% nitro the highest I can go before there are problems ??? Also would it mean tuning also the Engine ?

Okay I think this is all . Please do not ask me to read the other Hammer thread...Although ver
good but, left some questions to be asked.

Okay Regards for now...

PS: I do want to acknowledge that my selection on a starter nitro boat has all to do with
the gents on this forum...whom with out their assistance I sure would be up a creek
Thanks to all!!! Keep it up!!!!
