Hacker 9-cell motor with 7 cells...what prop?

Hi,
Seeing how fast plane Tuomas has I have to do something to keep up with him So I'm sure someone has already tried a 9-cell motor (I have Hacker 6L) with 7 GP3000's. Limiting factor most likely is the controller 70-pylon but I might change it to 105. So would CAM 5,2x5,2 be OK with the older 70-pylon controller which I believe can handle 85A max? The problem is that I'm busy studying and next chance to fly is in the competition so the setup should be proved to work

I fly the aluminium 6L with 7x GP 3000 and APC 5x5 prop ( I also tested the 5,5x4,5, but it gives less speed ) it is not as fast as the 9 cells carbon setup in the firsts laps, but a lot faster on the 2 or 3 last laps ... thz controller is my old kontronik 3SL...

Thanks Sebastien! I knew that 5x5 would be ok but I'm not sure about 5,2x5,2 which has actually 5,5 pitch. Have you ran your batteries hot like 60 centigrade? Low tempereture will slow you down in first lap. Is that 3SL a 70 amp controller?

Yes I run on hot batteries ( 70 ) the controller is the old 3SL pylon , and I get around 135 seconds of full throttle with the APC 5x5 wich is too much...
