Too Powerful Brushless ?
By the way the Araldite is very good glue but is brittle and as you have found cracks off with vibration. The other glues mentioned all have flexibility so will absorb any vibration.

Too Powerful Brushless ?
Hi traiderman I am no expert. dont forget, as pmdent highlights, you you multiply the KV by the volts of the supply to get the RPM of the prop. so you can play with the volts supplied or the Kv of the motor or both. regarding the vibration, …

Not thick at all, you only learn if you ask questions. ESC = Electronic Speed Control. BEC = Battery Eliminator Circuit. As to the rest I'm sure another member will put you right, try RNmunich he is well up on electrics. Cheers Colin.

Hi Spitfire Yes you need to isolate one of the BEC supplies from the ESC (red wire). You can cut the wire but I prefer to remove the connector from the plug, you will find a small tab holds the connector in place and if you carefully lift t …

3 x Brushless Motor control?
Exactly it's the control / operating principle which counts. You just need the appropriate ESCs for the type of motor you are using. I agree that TX mixing often has limitations. Maybe because they are designed for aircraft!? Doug

3 x Brushless Motor control?
at the risk of upsetting some apple carts get a taranis system then you can mix to your hearts content just plug each ESC. into its own RX channel and do your mixing on the TX.

3 x Brushless Motor control?
Hi Dave, I think that was the end of it anyway. At least from my side. it was more a comment on the operational principle than the motor type. Cheers Doug

3 x Brushless Motor control?
I agree Tom, Much easier. That's the principle I will be using on my destroyer refit. I have a combined twin-ESC and mixer module from Action Electronics and will have speed and steering both on the right stick. Greetings Doug
