I am a new Member to WattFlyer. I have been building and flying giant scale warbirds for years. I bought an ESM PC9 and decided to install an AXI 534514HD for power. I am controlling it with a Turnigy Superbrain 100A esc and two Gens 5300 18.5v battery packs. The Turnigy did not come with any instructions. I bought the programmer also. It has some instructions but not much. I have flown the smaller electrics but this programmer has alot more programming ability.

One thing that is messing me up is the programmer is asking for a parameter of either 8kw, 10kw, 12kw, or 14kw. I am at a loss with what it is asking.

Also I have the battery leads directly plugged into the batteries with no switch. I have to take the airplane apart everytime I want shut down the plane and to charge the batteries. What kind of switch would work to turn off the power to the esc?

Many Thanks

Default newbie questions

the 8 - 14 numbers refer to the pulse width (PW) at which the ESC is working. Most use either the factory default setting or 8. Going to a higher number gives more precise ESC response, but uses more power. Typically on competition pilots play with this number.

If you are using Lipos you should not charge them in the plane as a mistake could destroy it.

For saftey's sake most use an "arming plug." These go between the battery and the ESC, usually on the red lead. There are commercially available plugs or you can make your own using ths same style connector as on your batts and ESC. Basically an arming plug is a jumper that completes the circuit.

Hope this helps.
