The yellow one is the one I purchased. Followed the instructions posted here and IT WORKS! Now I need to decide if I want to mount it into an old K&O outboard or make an airboat/camera boat. But at least now it works. Thanks to all of you for the help.
If this yellow one is yours, it has a 5v 2A BEC, so you should be able to pug it in to the throttle channel of your ESC. Takes max 3s LiPo. If you are using a LiPo, you will need to set it to the LiPo setting. Should work on the set-up instructions .
Looking at your ESC pic there is no red wire as there is no BEC. Designed to plug into a drone multi controller it is possible that that unit provides the rx power, and will have a common earth (neg). The ESC requires a black neg wire and a white signal wire. If you are using a battery there is no common connection between the ESC battery and the rx battery neg. It may be built into the ESC wiring but this might be your problem.
I've printed out the firs page and will attempt to set the ESC tomorrow sometime. Your help (as always - is appreciated). It seems brushed motors (except for RFI issues) are a lot simpler to set up. Thanks again, and I let you know what happens.
