Default Questions on Hacker MasterSpin Pro 99, JR 12X, SpinBox

I am totally new to Spin ESC and SpinBox setup.
I've been using Castle until about a week ago, but found out the brand new Castle 85HV wasn't holding the rpm consistently, so swapped with MasterSpin Pro 99.
By the way, it is with Hacker A60-7S with APC 21x13.5E, and JR 12X.

Right now, I have prop ripping, so will have to change the prop before next flight. Probably will try 22x12 or something similar.

Technical data for A60-7S V2

Technical Data:

Powerrange max. 2400W (15 sec.)
Idle Current at 8,4V 1,2A
Resistance 0,026 Ohm
RPM / Volt 215 U/min-1
Weight 595g
Diameter 60 mm
Length 62 mm
Type 28-Pole
recommended Timing: 25°
Switching Frequency 8 kHz
recommended Prop APC-E 22x12 ~73A at 10S Lipo


Usually I setup idle using throttle trim. I have throttle cut enabled with value of 0. When I move the throttle trim to start motor, initial starting power is way too much (motor starts spinning and about 50% of trim) that the plane can't stay put even on tall grass. So, I have to back the trim back to about 25%.
Is there a way to start motor at same point where I want it to idle?


Current setting shown from the ESC are as below.

Temp Protection: 100 degrees Celcius

[b]Brake: Soft 30/100/1.5s

Switch throttle cut on. ESC should arm.

Will the brake is now active?

Jog throttle stick and return to idle
Fine tune the idle. You just do this once, it should be good forever after that.

For flight with brake throttle cut must be turned off ( Switch throttle cut off) ?

Viktor.

Turn on procedure:
Connect 10s pack.
Turn on transmitter at low throttle and not in throttle cut.
Turn on receiver. ESC should not arm.
Check all other controls
Switch throttle cut on. ESC should arm.
Switch throttle cut off

When you get around to using the brake we can talk about that.

OK Jim, I setup my throttle IAW your instructions. Much better than what I had! Now how about brake setup instructions?

Sorry, I haven't been following this thread. What you need to do to turn the brake on is have a switch to create an idle down. Most competition transmitters have an idle up or down function built in but in any case you need to switch the idle at low throttle stick position which was slightly over 1.1 msecs to something below 1.1 msecs. You can turn this on right after takeoff and have it on for the whole flight or switch it on and off as desired. The motor will not stop as long as you have some airspeed but could stop in spin entries and landings so be careful.

As far as the ESC brake settings you need to play around but I find 50% at max acceptable and I don't waste anytime delaying it.

Hope this helps.

Victor, for flight the throttle cut must be turned off or you have no throttle control. Therefore you need an idle down switch in addition to the throttle cut if you want to turn the brake on and off and have an idle.
