While we're on the subject of twins, I wanted to get your thoughts on what I've gleaned from various posts. Here 'tis:

1. I've been told a shottky diode in the red wire of each ESC throttle channel connection prevents them from "talking" to each other and the problems associated with that.<span style="color: #ff0000">No idea. </span>Allows the ESCs to both supply power for the radio. I flew a P-38 with a pair of Astro 020s and ESCs just simply y'd together at the Rx and never had a problem. I'm still wondering about that. <span style="color: #ff0000">If an astro 20 is a brushed motor, you can run two of them on one ESC. Brushless motors don't generally work well sharing an ESC.</span>

2. Many twins require the batteries to be a great distance from the motors in order to get the CG. This requires lengthening some wires. The consensus seems to be that one should keep the battery to ESC wires as short as possible, and use long leads out to the motors. I'm told that voltage spikes happen if you do it differently and that the big caps in the ESC overheat and die. I asked my primary ESC supplier (Flightpower) about this, and they more or less don't really care, but yeah, long wires between ESC and motor is OK. <span style="color: #ff0000">I have no experience around this that I can share.</span>

Thanks in advance for your thoughts on this.

I've got three E power conversions I've done recently. PM me if you'd like the details and the results.

Cheers
