Hi guys, I know this is late but I have had a lot of experience with the BR thrusters and mounting them on steerable mounts. (See the old thread on Azimuth Mounts). I have broken many Servos, BEC’s and T200’s because of the steering.
Firstly, turning the T200 whilst under load or high RPM creates a fit bit of centrifugal force on the Stator tube. Due to the design, the magnets create the rotating mass. It is like spinning a bike wheel and trying to rotate it just by the axel, it is difficult. I can report that the T200’s are now up to the task. I have been providing feedback to Rusty and the boys and they have improved the strength of the Stator tube to handle the extra load put on them.
Servos. Well I have killed my fair share of them. Forget the hitec WP units, they aren’t up to the task. Once again, stationary with no rpm, they turn fine. Under load the force required is greatly increased. I now use Some of the higher rated Savox servos (30kg+) to do the job. Then that causes another issue…
BEC. I use the Castle Creations 20A BEC. The BEC in the ESC can’t handle the current required. I found this out early on when doing a few turns, it would stop responding to turns. Stopping the boat gave me back my steering after a few seconds. Once again, the torque required to turn the motors at speed creates great load, maxing out the Servos and then the BEC.
Yes, I have gone overkill on the BEC & Servos but that is better than waiting for the wind to blow it home.
