tigerman Posted October 14, 2019 Share Posted October 14, 2019 I am flying a Freewing F 86 which has a 3530-1680 KV 12 blade outrunner with a 80amp speed controller EDF fitted .It fly OK but a little bit under powered in my opinion ,it only just get airborne and then you have to fly it on full throttle to keep it flying .Freewing have just brought out an upgraded version with a upgraded motor a 3658-1857 kv motor with a 100 amp speed controller .These number means nothing to my small brain .So in layman terms will the upgrade 3658-1857 inrunner motor with a 100 amp esc have more power then the old 3550-1680 with a 80 amp esc and make my take off and flying a lot better ????

Simon Chaddock Posted October 14, 2019 Share Posted October 14, 2019 Yes but the flight duration will be shorter in proportion to the increased amps. You really need to measure what the Amps actually are with a Watt meter to work out what the reduction in duration is likely to be. You don't get something for nothing.

Frank Skilbeck Posted October 14, 2019 Share Posted October 14, 2019 My reckoning is that it will be approx 20% more powerful, so will consume 20% mare amps at full throttle. Measuring amps and volts is a good idea as it maybe that your batteries can't maintain voltage at high amps and some better batteries would help also.

tigerman Posted October 14, 2019 Author Share Posted October 14, 2019 That makes sense .I have been told to try 60c rating Lipo for EDF but I have always believed that most c rating are wildly exarate and most 60c rated are normal around 30/40 c . Anyhow I have order the upgrade ,I let you know what the difference is when I get it Quote Link to comment Share on other sites More sharing options...
