Finishing brushless LST, some problems I need help with

[Robl45]

Yes I have the Y cable. I think I may have solved the brake problem, when I moved the linkage, the way I had it connected was binding I believe against the servo case. I will know more when I can try it again. I shredded the spur gears so have to replace them tomorrow.

I soldered the esc wires directly to the bullets coming off the motor. The motor was used and the bullets were basically right at the can so I didn't want to disturb them. I just set it to the settings I thought it should be at. Not sure if there are optimum settings for the feigao.

http://www.bphobbies.com/view.asp?id...B3455156&img=l This is the esc I'm using and I"m using a pistix to make it work with the piston transmitter.

Settings are below. I am using the 6S cutoff as I"m running 6S on the feigao 11xl

No brake,

3 degree timing and 8khz setting.

1. Cell Type and Number of Cells
•— 1 Short + 1 Long NiMh/NiCD Auto Cell Count - 0.8V/Cell Cutoff Voltage
•— — 1 Short + 2 Long 4S Li-Po (14.8V) - 11.6V Cutoff Voltage
•— — — 1 Short + 3 Long 5S Li-Po (18.5V) - 14.5V Cutoff Voltage
•— — — — 1 Short + 4 Long 6S Li-Po (22.2V) - 17.4V Cutoff Voltage
•— — — — — 1 Short + 5 Long Do Not Use
2. Brake Setting
••— 2 Short + 1 Long No Brake
••— — 2 Short + 2 Long Soft Brake
••— — — 2 Short + 3 Long Medium Brake
••— — — — 2 Short + 4 Long Hard Brake
••— — — — — 2 Short + 5 Long Do Not Use
3. Timing Mode Setting
•••— 3 Short + 1 Long 3º - For 2-4 Pole Inrunner Motors
•••— — 3 Short + 2 Long 8º - For 6-8 Pole Motors
•••— — — 3 Short + 3 Long 15º - For 10-14 Pole Outrunner Motors
•••— — — — 3 Short + 4 Long 30º - For 10-14 Pole High-RPM Outrunner Motors
•••— — — — — 3 Short + 5 Long Do Not Use
4. Pulse Width Modulation (PWM) Setting
••••— 4 Short + 1 Long 8KHz – For low RPM and low pole count motors
••••— — 4 Short + 2 Long 16KHz – For most outrunner motors
••••— — — 4 Short + 3 Long 32KHz – For high RPM outrunner motors
••••— — — — 4 Short + 4 Long Do Not Use

Remove the brake linkage from the servo and verify that it is moving the same amount both ways without the load. If not check you radio settings, or try another servo.

Are you using connectors between the motor and esc? If so they may not be making good contact. I usually direct solder the motor and esc wires, once I have found the correct hookup for motor direction. That is sometimes the cause of stuttering during startup.

And a pic or two of your setup may help diagnosing the problems.
