Why am I slow?

OK, then next test will be a longer run with the Hyperions and then I will also try the Flightmax 2200's and see what they can do. Thanks for the idea.

One other thing I am wondering...could the EZRUN 60A ESC be holding me back. I wonder if it would go faster with an MM in there...

i'm one of those people that says you can never go too high a limit on amps for an esc. with lower voltage (ie: 3-4S), there are so many voltage spikes, that i would opt for a higher rated esc.

is this limiting your top speed? many would say no, but i'm not entirely convinced especially with the capacity of these motors. typically, in escs like the mambas or tekins if it was exceeding your escs capacity it would likely reflect in esc temps or damage but not having the ez run i couldn't tell you for sure.
Here's an exapmle: one of my friends got an RX8. he saw an increase in top speed over his 150A ezrun. was that the lone factor or was it a near perfect speed run? he says it's the rx8. only a data logger could say for sure with all other variables equal.

The power of the motor is limited by the provided energy. I think everyone has experienced "good" or "excellent" lipos. a battery that performs better under load and thus provides more voltage ("punch") would be an option (4s). there is a lot of marketing, "paper doesn't blush". just a high c rating doen't always have to mean that the lipo has a great punch. for example on this (german) page that guy is testing various lipos. the conclusion of a 20/30c flighpower is, that it performs well up to 15c and is a good 15/20 c but NOT a 20/30c lipo, but permanent 20c is too much http://www.elektromodellflug.de/akku...htpowerevo.htm

just adding a new 3s lipo to get 5s might be a problem, when you're mixing batteries they should be in the same condition/age/capacity/manufacturer.

maybe the esc is also limiting the performance. I mean, going 70+ is not quite usual for that esc.
cool project! I like!
