Weird control
« on: June 02, 2024, 05:39:23 pm »

Today I noticed an issue with the set up in my 1/72 Leander. Individual esc one red wire removed  left motor on its stick is fine but if I try using right stick, at low revs both props turn with left direction being reversed. Once stic is pushed to higher revs both motors settle down. Esc are mtoronik
So help please %%

Can you provide a photo or drawing of how they are connected?

Apart from the minor detail of a red wire removed from a servo plug, or two with a receiver pack, Rob indicated several boats wired as in the diagram.
Many people do so without a care and some loose escs as a result.
So far he's down two escs.
I've been cautioning in person for as long as I remember. The diagram is a version of one I posted on a forum about fifteen years ago. What prevents a catastrophe  is higher servo lead resistance to that of the black wires to the junction. This connection induces electrical noise on top of the pwm signal from Rx to esc and the current can be enough to fuse a track within the esc.

I'm  a little confused. If you want to run two motors on two separate  channels  with their own escs, so that one  could go forward while the other was in reverse if you so wanted, how should you do it?

Does the transmitter have a mixer function enabled?
