I made the signal converter myself using ATtiny2313. Then we can use a regular brushless ESC and brushless motor on the main.

On that tail side, as the 2416V uses a 0.5ms cycle, to convert it to a regular ESC/servo signal the cycle time is 20ms. Hence we are lossing quite a bit of responsiveness across the conversion. Not sure if it would be a problem.

We also use a proprietary cycle at the tail, like the 3.3ms cycle time in the 2433, but we would need special servo to handle the much shorten cycle.

That won't be too much work on the ATtiny2313, we just have to use 2 seperate counters.

The 2416V also requires a power check input of around 2V. If you don't use the stock "ESC", don't forget to do that, otherwise it would keep the motor outputs off.

Have fun.
Can you say that in english now????
