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.

Brushless motors
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 …

Brushless motors
Hi Spitfire, Sorry NO! This is because the ESC needs feedback from the motor providing info on the position of the rotor and thus provide the correct phasing; either via a shaft position sensing system or by the back emf of the coils in the …

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
