john stones 1 - Moderator Posted April 29, 2014 Share Posted April 29, 2014 Hello all Have been using Turnigy Plush E.S.C's up to now, I was told they where good problem is they never have any, name me a brand I can rely on please 50 amp size Thanks John Quote Link to comment Share on other sites More sharing options...
Depron Daz Posted April 29, 2014 Share Posted April 29, 2014 I've never had any problems with the Giant Cod/Shark ones. Think they're called Pentium or similar. I've had all sizes up to 80amp. Quote Link to comment Share on other sites More sharing options...
Pete B Posted April 29, 2014 Share Posted April 29, 2014 Hobbywing Pentium, Fentium or Flyfun are all the same ESC as the Plush and can be found at many outlets, such as Modelaccessories. The Pentium is my ESC of choice for reliability. Pete Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted April 29, 2014 Author Share Posted April 29, 2014 Thanks Daz Also how do I work out what size ESC. for a given motor, its not always stated. What is it in the specs that ables me to work it out ? Thanks John Quote Link to comment Share on other sites More sharing options...
Pete B Posted April 29, 2014 Share Posted April 29, 2014 Sorry this will be a rather stilted answer but I'm on the Hudl.. It comes down to the number of amps you expect to draw, John. Say you want reasonable performance from a sport model, you'd be looking at around 100w/lb. If the AUW of the model is 3lb, you'd be wanting about 300 watts. You then decide how many cells in the flight pack. In this instance 3S should be fine. Take a nominal voltage of 10v for simplicity, 300w/10v = 30A. Give yourself a bit of headroom to not overstress the ESC and you'd be looking for a 40A ESC. A 5lb model,for the same performance would need 500 watts. On 3S, that would draw 50A, which is getting onto ground where the motor might complain, not to mention the wiring and connectors. In that case, you could use a 4S pack, nominally 14v, so 500w/14v = 35.7A, much kinder on the system...... You'll see that most motors will have a recommended voltage range and a maximum amperage. By perming the volts/watts and amps, you should be able to come up with an acceptable combination.
