Not happy with Brushless Jato :( -

Well, converted my Jato to brushless last night in a few hours.
For the innitial attempt I used:
-Mamba Max speed controller
-Mamba Max 7700Kv motor
-17t pinion
-55t spur
-Venom 7.2v 3300mAh pack
All of the above was brand new..
Anyways, I got everything setup and ready to rock, calibrated the ESC... Went for the first test spin around the shop, first thing I noticed was the motor sounded very weak and was obviously not getting anywhere near the RPM that my 18th scale Mamba's were getting.
Continued driving, still not impressed. I was probably getting 25-30mph top speed, if that.
After a total of about 30 seconds of driving, the truck stopped dead. No response at all......
After some looking into the problem, the BRAND NEW, 30 seconds of use speed controller is completely DEAD! :mad:1
I fired off an email to Castle Creations in regards to warranty. I am expecting it to be replaced no charge!
Anyways, I'm hoping someone can re-assure me that this thing WILL be faster than the 25-30mph I saw during the innitial test drive... I'm really hoping the bunk ESC was severely limiting performance, and that I didn't waste $300 on a slow ass setup..:031:
In all reality, I only make changes if I expect them to make the truck/car faster... I'm really hoping for this thing to be faster than my Jato 3.3 was.
Also, just reading Castle's website last night, the 7700Kv motor will not do 3s lipo, which was my plan. The 7.2v pack was really just for testing purpose untill I can spend $200 on a phenominal lipo pack...
In all reality, I am aiming for a minimum of 70MPH with the BL setup... I my 3.3 did 110km/h or roughly 65mph being chased down a highway in a car...
If I can't run 3S lipo on the 7700, what other motor can I upgrade to to get me to my minimum of 70mph goal on 3S lipo?
