Default Throttle Curves for 3500kv and 4400kv

I was wondering what are some good numbers to start out with my 450 I use a 3500kv sonic motor and a 2221-6 scorpion motor. Im using the 3500 now. Not a total noob but not a pro what would be good for some med stick banging and mild arial tricks.

Use the standard curves that are out there. Stuff like what is in the owners manual or finless video.

Normal 0-40-60-85-100
idle 1 100-92.5-85-92.5-100
idle 2 100-100-100-100-100

The thing to do really is to gear it according to the motor and headspeed you are looking for. For example the -6 may be geared with a 10 or 11 t pinion. The 3550 motor needs something like a 12 or 13tooth pinion. Lower pinion for milder flight...higher pinion for more aggresive stuff. Headspeed would still usually be in the 2600 range for the low end ...and then 3200 for the higher end of the spectrum.
