Default Hyperion 550's

Hyperion 5-fiddies rock! I know this is off topic (actually wrong forum as this is related to my mini cp, mcpx build is on hold for the moment) but I've seen several posts asking if a hp05s can be run on the 300mah cells. Yes but it's not optimal. I was getting 7 minute flights with 350mah 25c cells and am now getting the same 7 minute flights but my headspeed went from 8,150 to 8,640 rpm and thrust went from 200g mid stick to full - pitch, 120g continuous to 250g mid stick to full - pitch, 170g continuous. I can't wait to fly it tomorrow, it sounds so awesome. I need to put on a smaller pinion and possibly a larger main gear to drop the headspeed. 8,500 sounds wicked but does a lot of damage in a crash and also eats more battery than a saner rpm would.

14.7g before w/ jst & wire, 14.1g after w micro deans and no wire:

30 minutes at only 1c!!!

All up weight: (will lose around 5g soon)

The 7mm tail held before but with the new found power I don't think it'll have a chance. So:
