I have the following setup:
Swift
Z30A-1100
10t pinion
5S TP 3300's
NHP Razor Pro 530's
Have set the esc to govenor mode, but headspeed seems very low. I have not measured it.
Think it's something to do with the setup of the esc? Does anybody know how many poles the Z30 has?
The esc has 3 gov settings, for 3 different 'electrical rpm' limits which are for 2 pole motors and need to be divided for more poles. I may have the limit too low...

in z30 or 600+ = 8 poles.
usually in esc you have 2-3 gov mode = low and high, or low-medium-high. change your setup to medium or high and testing.
you can calculate maximum rpm =1100kv x 3,7v x 5cells x 10/96gear x 90% effect.motor = 1907 it too low!
f.e. my setup (soft 3d) pinin 10t, 600+, fp6s1p, cc80.

Ta, will go to the higher setting, change to 11t pinion and go from there.
I'm doing 8 mins of hovering/ff and only putting back 1500mAh....

for good powefull fly you need 2000-2100rpm at minimal works voltage (appr.3,3volt per cell). f.e. 2100rpm x 96t/5cell/3,3v/1100kv/90%=12,34 --- 12t pinin (all for governor mode).

hello !!!!
i fly my swift16 with 5s1p flightpower 5000ma and a tango 45-10 (1050 kv ) + 11 t pinion .
in iddle up , i put 90% .
i don't take the speed of the rotor but it fly very good ( little 3d / flip / looping ...) .
i fly 6 min for 4000 ma .(80% of my 5000 ma lipo ) .
for 100% in iddle up , i may have 2000 tr (swift tuning ) so , with 90% , i take only 1800 tr ?? :shock: .....
i would want to know if it's better to fly with 100% in iddle up or with 90% ??.
is the motor take more intensity with 100% ???in this case , i will lost time fly ??
or , is the motor prefer to turn on 100% and take less intensity then when it turn under 90%??
thank'you for your answer .
ps / i'm french so sorry for my bad english :oops: .
bye , have good fly ....bulldog :glasses2:

I'm fly in Swift one year (from 12.2005). It very nice model for me - I've sold all my nitro ang gas - now only electric!
I tried for Swift-tests different rpm's from 1700 up to 2500(!). My result - hovering 1800-1850 (stably and economically), 3d - 2000-2100 (good dynamics and control). At calculation of governer-mode I use such minimal voltage of LiPo-batteries:
3d: 3,3volt x 6cells x 1110kv x 10/96gear x 90ïfec. = 2060rpm
hovering: 2,9volt x 6cells x 1110kv x 10/96gear x 90ïfec. = 1810rpm
It is important - when in flight the battery falls, governer can not operate stably more and rpm go to "jumping". Then you to switch mode "hovering" and rpm are reduced and stabilized, and you can landing model w/o extrem autorotation.
Good fly!

hello ddgeli !!!
in order to understand , in your calculation , it's with iddle up = 100% .
tank you for your answer .
bye .

Thanks chaps, having a battle with my metal grips but hope to get the Swift in the air at weekend

it is not a =100% of throttle, it is not a curves - this is governor mode. (sorry for remind - governor is automaticly stabilized main rotor rpm's ) if you like to fly in throttle curves, i'm guess that with new-charged batteris (3,7volt per cell of LiPo) you can calculate maximal 2300rpm. i've tested 2500 - it so more.
for example your setup: 2300rpm x 96/1050kv/3,7v/5cells/90% = 12,63 tooth pinin, normally 13 or 12.
