ESC Hobbywing - headspeed with E7 ??

[Stefan22]

hello volks, just came from "running" in my brand new E7 - nice heli ...
just wondering, due to the fact, that I opened my installed HObbywing 130 Platinum ESC, with about 85% at my Transmitter, but the headspeed of the helicopter seems to be quite low .... The throttle curve is correctly learned.
About 1700 rpm.
I'm using a brand new lipo 12 - 5000mAH from gensace , the cells have enough power.
Could it be, that with the standard 12t pinion, the gear ratio is to high (about 10) - so it would be really necessary to go up to 13t pinion to even reach about 1900 headspeed ?
Hobbywing explicit suggests not to increas the esc throttle gain over 85% - to heave some air for control the headspeed.
How much headspeed do you get out of your E7 - with the 12t pinion and how wide open do you have your esc ?

Need more info to answer, what kv motor?

[Stefan22]

...it's a HK4525 - 520kv motor.

520kv and 12 pinion is a good match for 1850-2150 headspeed. Try redoing your gov settings. I'm running Xnova 4525 530 and 12t pinion using Ikon gov. My headspeeds are 1950 to 2150. Also have another E7 with Xnova 4530 480 with 13th pinon on hobbywing gov. Do believe throttle is at 78% for a 2100 headspeed.
Sounds like you need to double check your gov setting.

Maybe redo endpoints between tx and esc then redo them between fbl, tx and esc.
