Hi all
Rod was Asking what type of setup would power his F-18 Blue Angels EDF Plug-n-Fly RC Jet from hobby king as it was a bit sluggish on maiden but improved with 40 c rhino 2250ma 11.1v battery.
It appears that the motor in the f-18 is similar to Jetiger stock but 4300kv and as i experienced it did not like 4s lipo as i burn't stock motor out after about 6 flights even with throttle management.
Here is my Jetiger Specs that i currently using, 4 min max flight running 4s lipo and running motor over stated current i think as it does not specify max current and it seems to be holding strong after many flights, ( full throttle management being used )
But Flys fast and well at about half throttle which i reckon is about 40 amps
JETIGER - 571 GRAMS WEIGHT PLUS 220 GRAMS FOR LIPO BATTERY TOTAL WEIGHT 791 GRAMS
BATTERY - 14.8 V 1800MA 40C LIGHTMAX
SPEED CONTROLLER - TURNIGY 80 AMP
DUCTED FAN - 64MM 7 BLADE DESIGN HIGH STRENGTH HOBBY KING.
MOTOR SPECS -
Model : D2830-4000
Airplane Class : 740-1060g
KV (rpm/v) : 4000
Voltage (v) : 11.1-14.8
No Load Current (A): 2.6±0.2 @ 11.1v
No Load Speed (rpm) : 43500±5%
Load Current (A) : 28.0@11.1v
40.0@14.8v
Load Speed (rpm) : 39300@11.1v | 49900@14.8v
Recommended ESC : Turborix Advance 60A ESC
EDF : 64mm
Pull (g) : 740-1060g
Weight : ~77.0g
Packaging Weight : 115g

Actual tests with wattmeter and thrust test after 15 sec on full throttle -
14.8volts ###67 amps###1013 watts###830 grams thrust
11.1 volts ###52 amps###592 watts###630grams thrust Which i haven't yet test flown with 3s as more power on 4s is
The edf that i am using with 7 blades is strong unit but seems to up the amps quite a bit and i think a 6 blade version would be more efficient but finding a strong edf as the stock 64mm unit was too flimsy.

What Do You Mean Theres a Throttle Curve ?, Its Either all the way up or all the way down
