Castle Creations Programming?
I have the short course edition.
Most of the settings are pretty straight forward. What exactly does the timing do for my motor? I was told that increasing the timing is kind of like downsizing pinion. It will give me more punch to get over large jumps. I know that the Tekin setup has 2 timing settings based on info from Tekin users. One timing setting is for low end punch and the other is for top end. Does the Castle system have the same effect? My top end is fine because I can keep up with others. But, when it comes to , lets say coming out of a corner and hitting a jump, that's were my setup seems to fall short compared to others. |
Here is timing advance explained by Pdelcast (Castle President) on RC-Monster:
Timing Advance -- Let's see. Timing advance is just like the timing on a 1:1 car -- In an internal combustion engine, it takes some finite amount of time for the flame front to burn through the gasoline/air mixture in the combustion chamber, so the spark plug is fired early -- to make sure that by the time the piston is at top dead center, the fuel is mostly burned, and cylinder pressure is near maximum -- making the most power. In an electric motor, there is an effect called inductance -- inductance is a resistance to change in current in a circuit -- so current ramps up and down, and doesn't change instantaneously. At low timing, the controller is actually centering the current ramp on the switch of coils, so that the efficiency of the motor is highest. But-- it is also possible to advance the timing even more, which increases the amount of current drawn by the motor (and therefore torque) -- however, this also increases (significantly) the amount of current drawn by the motor when the rotor is in a position where it doesn't generate torque efficiently, lowering efficiency. So timing is a trade-off of torque generation (power) and efficiency. Above a certain amount of timing advance, and the rotor actually starts generating REVERSE torque for a short period, and then efficiency drops very quickly. |
That was a great explanation simplechamp, but I will try to make it a bit more clear for the average user.
Increasing timing will increase high RPM power, at the expense of heat and runtime. Sometimes on a slippery track a high timing setting can also be used to tone down the acceleration. Lowering timing will increase torque, lower temps, and increase runtime. Of course there is a limit to how far you can go before negative effects take place. In a sense, increasing timing appears to have a very similar effect as increasing pinion size, but on a smaller scale. None of these rules are set in stone and each motor/ESC/Car/Truck/etc, can react slightly differently, so always monitor motor/ESC temperature when you change something. Keep your electronics at safe operating temperatures and you will not do any harm by playing with the settings to find what works for you. |
Thanks for the info!
I had the punch control set at default or "0" I bumped it up to 25%. That's the beauty of bring the laptop to the track. Quick changes. So will bumping it up to 25% help me achieve what I'm trying to accomplish? |
If the punch control (or Torque Control) settings don't help with the acceleration curve, it might be your batteries. I had similar issues with my
TC running a SideWinder. As soon as I got better rated batteries - the acceleration out of corners got better. |
