Default Maiden Trex 700 DFC Pro RCA MD500

Flew the maiden on my First Scale Project. Here are the specs
Rc Aerodyne Hughes MD500 700 size Fuselage
Trex 700 DFC Pro stock 112 main gear 12 pinion 520kv Align Motor
12s 5000mah batteries total weight with batteries 15lbs 4 ozs
Castle 120HV ESC with Ikon FBL Controller Ikon Gov at 1600rpms ESC at approx 70% throttle
Flight time seven minutes 10 seconds with 52% left in batteries
To be honest CG is perfect when I pick it up on the button I cannot tell whether the front or the back skids liftoff first

Extremely pleased with setup except for heat inside the fuse , motor ,esc and battery's were very hot after first flight.

DFC was rock solid and very stable with Ikon, alot of comments that said DFC head was to sensitive take a look at the video you be the judge.

The only thing I am worried about is heat I need to throttle up the esc from 70% up to 90% but I dont want 1900rpms. If I go to a 10s setup that would put my esc at 90% at1700 rpms or so. Would that help or hurt the heat problem and would I loose any power on climb out or manuvering
