Well, I guess that's why the Sentilon is $100 and the HV-110 is $270. The WOT speed makes no sense IMO. Have you tried setting the EPA to something above 100% after calibration?

You can actually get the HV-110 for $200, if you use Tower and their coupon code things. I got mine for $229.99-$30 back in July of last year.

As a little update on the sentilon esc, itd be fine for a speed machine, but i've figured out the delay thing

If there's always a bit of throttle happening, its got great punch. if you back off completely then try to accelerate again, you get a delay (As a result of this soft spool up thing). Basically it means if your ever going to or want to jump it, drift it, or race it, its very bad. You can't balance the vehicle in a slide or in the air because of this stupid delay. I mean, you can, but its not instant response like we're used to - you can kind of counter it buy taking the delay into account but it just wouldn't work properly. Looks like I'm gunna start saving my pennies for the mmm release (which I was doing anyway lol)...
