The Hummer video was on 3 cells. We used a TP 1320 PL and an APC 4.75x5.5 with an AUW of 9.4oz's. The speed was measured in level flight on the 297' pylon course. Watch the video again (in my gallery) and the last pass was from a 400' dive! That pass was 163mph
My 24" Bandit goes 90+ mph with an APC 5x5
Not bad for a foamie!
With an APC 6x5.5 it has unlimited vertical and will do 70mph loops
I've attached a couple shots of my Bandit.
Were you using a 1320 Gen II pack or a Prolite? Your specs seemed a little soft? I get 17,400 rpm's on 17 amos and 175 watts. Confirm your battery for me please.
