# How to use an ESC

I'm new to RC related modules. Today I got my Hobbywing's Skywalker 20A brushless esc. Manual is here.

I also have a brushless outrunner motor (HL3512)

I don't have any device to program the esc's (even the seller hasn't mentioned about such requirement).

The manual talks about programming by listening to the beep patterns. But for that it seems that the esc should be connected to a flight controller (it talks about throttle positions etc...). But I don't have any flight controller.

Can some one tell me how to use the esc with what I have? (I have 2200mAh LiPo and arduino mega too)

• @CodenamedSC thanks. I couldn't find any helpful article regarding the matter on the internet. Hope this is achievable.. – David Oct 2 '12 at 18:09
• For many of these, you may need a convenient way to adjust the pulse width (comparable to moving a transmitter joystick) in order to navigate their setup programs, which consist of a series of audio cues made from the motor windings which you react to with the transmitter stick. This lets you program limits, braking, soft start, reverse modes (if present), etc. – Chris Stratton Oct 2 '12 at 20:52
• I know you asked for testing with what you have. But if you're willing to spend a couple dollars more you can get a simple servo tester with which you can play with the combo. Most hobby stores sell these. The servo tester is usually used to test servos with, but it can drive an ESC (+ motor) just fine.

• Thanks a lot @Casper ! never knew about such module. I'll order this module.. – Anubis Oct 11 '12 at 3:32
