When you said "I will change with a 7 cell 3300 mah GP and see what happens"
I wasn't that clear in stating that upping by one cell to seven resolved the 'basic JJ starter motor' spool up problem for me and was confirmed by Gasper the FADEC designer regarding low voltage drop on run up. I missed the move to 8 cells though I also replaced the electric motor but have used the Chinese motors for Twister or Honey Bee Electric Helis are rated for 8.4 volts, and are a direct replacement. They can take 9.6v and cost as little £4 or $7 online.

If you want one FOC just PM your address over you might get it in Saturdays post. The higher revs on the starter motor are a real direct benefit. Combined with a 'ramp setting of 6' and other parameters suggested today get the JJ1400 up to idle quicker before ever hitting temps any where over 700C+ The dropping voltage on the pack will effect the start up success rate. The leaking fuel is going to effect running, as it will effect the CC pressure as there is also likely an air leak. Its strange for the factory to set up the FADEC parameters with the 'fuel ramp as low as 2' from whuich is where you first started from. Anyway the leaking fuel could well be the manifold problem but that then would be a warranty matter.

"Full throttle again and the max rpm still 130000. On all three runs the EGT was 720 Celcius which seems too high i think" Indicates the typical CC problems well known here that scuppered the JJ German importer for Europe.
