Solved Do i need to synchronize multiple motors on an electric RC plane?

[SirLearnalot]

Hello i am building a replica Ilyushin IL-18 which has 4 propellers. I was just going to use brushless motors to build this project but i keep seeing things about syncronising the motors and i am very confused, do I need to do this? I am using 4 separate ESCs.

Many thanks

If you calibrate all your motors properly using your radio or the flight controller if you have one it should be alright.

You will need to calibrate the ESC's once you have all the electronics put together and bound. With the props off, turn on your transmitter and set the throttle to full. Plug in the battery and wait till the beeps stop, then put the throttle to minimum. When the beeps stop again, you are calibrated

The only thing I would add is to do just one at a time so you don't have 4 esc's beeping at you all at the same time. They don't always initialize at the same speed so you may miss one.

Also be sure to use 4 identical ESC’s and motors to get the best chance of equal performance.

As stated above you need to calibrating the ESC’s (synchronize), you are showing the ESC what high and low throttle looks like. The goal, have all the motors start at the same time and operate at basically the same speed.

Thanks mate

One question for people who might have built a 4 engine- did you use counter rotation and if so how was it set up?

Someone here built a C-130 in the Blue Angels "Fat Albert" livery (I forget who - speak up and tell us!), and used counter rotating props on each side to correct torque. From what I saw, the thing flew great in the vids!
