I was told any brushed esc over 25amps by the guy from SH Grainger. Well, that's what he sold me to pair with the 850's he sold me at the International Model Boat Show at Warwick last year. I decided to go brushless after that, so, motors and esc's are sat in a box in the garage, so I don't have any practical knowledge, sorry. Just what I was told. Best wishes, Dave W
Hi Sonar, if you are running 2 motors, make sure you have good capacity in hand, these are powerful motors and need a good ESC to handle them, i used one with a chinese "50amp" esc and it produced magic smoke within a few minutes, changed to an Electronize and its run for 2 years now
I do believe the link is to ESCs similar to those Mark (jarvo) referred. I have a box here with about six that have been pulled from club member's models. They all appear to work (in a fashion) but exhibit a range of problems in the model from erratic running, stopping to smoking. Personally I would not use with any motor drawing more than 10 amps. Most of mine were used in fast models with big motors and seem to have lost the designed control spread resulting in little control from stop to full. It could be there was a bad batch and Mark, I and my fellow club members all bought from the same sources as we all live in the NW. The very max volt is 12 so it could be a fully charged SLA caused the problem Dave
in my S-Boot and PT boat both driving 3x motors ie MFA 850's and Graupner 600's those Blue or pink ones I had trouble with as with Not electronize but the other ones.They are car ones and you could probably get similar ones in the UK . They may be chinese amps but they handle 40amps plus no bother
Hi camyaj I have used similar and they do work well and I agree they can handle high currents. I do have one reservation as the web link show Tamiya connectors to the battery and I believe these are rated at 15 amp when new. The Tamiya site has a discussion on connectors https://www.tamiyaclub.com/forum/index.php?/topic/56075-tami... I replaced my connectors with Deans and have had no problems. Dave
