Steve Oliver 1 Posted March 19, 2013 Share Posted March 19, 2013 Hi. Please help. I am new to this site, I have made a few requests for help but so far had no replies so I hope someone will reply to this one. I have installed a E-flite power 90 motor in a Wot 4 XL along with a hobbywing 100amp HV esc. I was wondering if anyone has a similar set up, and if so what timing setting was used on the esc. I bought the esc from Giant Shark and on their web page it says that the high setting must be used for some high power motors or the esc will burn out. The problem is they don't give any indication as to what is considered to be a high power motor. Some of you guys must have used esc in your models so I would appreciate any help you can offer. I will be running the motor on 8 cell but cant give any readings as I have not run the motor fearful that I might damage the esc. Steve.

Eamonn Fahey Posted March 20, 2013 Share Posted March 20, 2013 Hi Steve and welcome to the Forum. Sorry that I don't know too much about high voltage electrics but I'm sure someone else will be along soon with an answer. Quote Link to comment Share on other sites More sharing options...
FlyinBrian Posted March 20, 2013 Share Posted March 20, 2013 Does the data for the motor suggest max current draw and prop sizes for given cell counts? if so connect a Wattmeter or Ameter in circuit and check the current drawn as you run up the motor Edited By FlyinBrian on 20/03/2013 21:26:01 Quote Link to comment Share on other sites More sharing options...

Nev Haycox Posted March 21, 2013 Share Posted March 21, 2013 Hi Steve, Do you have the instructions for the ESC? If so do you have the options under timing for 0/3.75/7.5/11.25/15*/18.75/22.5/26.25 Deg. If you do, looking at this LINK shows that you should set the ESC to 22.5 deg for a Power 90 I hope this helps. Nev. Quote Link to comment Share on other sites More sharing options...
Steve Oliver 1 Posted March 22, 2013 Author Share Posted March 22, 2013 Thanks Nigel, that will help me. Hi Racing snake, the only options I have are low, med and high so it looks like high is going to be my bes option as med is upto 20 deg and high is for timing above 20deg. Thanks for the help, it might well have saved me from a burnt out ESC. Quote Link to comment Share on other sites More sharing options...
Steve Oliver 1 Posted March 22, 2013 Author Share Posted March 22, 2013 Nigel I have just compared the information on your link to the information given on other sites selling the e-flite power 90. On your link it shows this motor having 12 poles, others show it as having 14 poles. I wonder which is right. I will have to look inside the motor to double check this.

Steve Oliver 1 Posted March 24, 2013 Author Share Posted March 24, 2013 This site shows 14 poles. for the same model number! http://www.spektrumrc.com/Products/Default.aspx?ProdID=EFLM4090A Quote Link to comment Share on other sites More sharing options...
NigelH Posted March 24, 2013 Share Posted March 24, 2013 I was thinking that there could be different Kv ratings when I found the original link and looked again just now. I only see 325. My link was to the manufacturer's manual. Their site also says 14 poles. What does it say on the one that you have there ? Or check your motor.

Steve Oliver 1 Posted March 26, 2013 Author Share Posted March 26, 2013 Mine is 14 poles Quote Link to comment Share on other sites More sharing options...
Steve Oliver 1 Posted March 27, 2013 Author Share Posted March 27, 2013 I have been in contact with the site that states that this motor has having 12 poles and was told this. "We were told that this motor had 12 poles" They are now updating their site to show that this motor has 14 Poles. Quote Link to comment Share on other sites More sharing options...
