I am currently running the 36-55-1 on my recent build
I have 3s 2200 mAh packs, 4s 4000 mAh packs, and 6s 2600 mAh packs available at my disposal.
I have tried to fly with a 6.5 X 5 being the largest and my ESC hit it's high voltage cutoff. I have flown with as small as a 5.5 X 4.5 being the smallest which has given me the most power / speed. That prop was the one that I ran when I had the 133 mph run. I have flown with a few other props inbetween those 2 and didn't achieve the results that I was looking for.

Unfortunately, it seems as if you have found yourself with a BIG, strong motor capable of awesome power, but its kv is way too high for you to get much more speed out of it with a 5.5 inch prop. Is there any consideration of rethinking what was suggested previousely and getting the same size 2 turn, or the next size up 1 turn to LOWER your kv which will allow you to bring in a bigger prop and use your batts with more cells ??
Remember,
more cells = more power,
more power = more speed
