Hey guys how is the racing going?? I am only posting to show you all the results of my latest Mamba Testing. I bought a GPS off Ebay and it arrived last night. I strapped it down today experimented for a couple of minutes with some gearing and settings and this is the result. 57.3mph This was using 19/86 gearing. I think that there is still more left in it but I ran out of room on my street. I also measured my normal bashing gearing with the 3s lipo and got a top speed reading of 48mph. I am going to go out and measure speeds on my IB4200 pack later today or tomorrow. I am still shaking from that last run!! Here is a little pic for some proof.
