Title: which Brushless Motor for 70mm EDF ? Post by: RC_DUDE on March 24, 2012, 06:04:31 PM I am planning on building my first rc plane , it would be an EDF plane with 70mm edf unit , the amount of thrust I want from it should be between 800g - 1200g ( could be more but then i hv to use 5s-6s lipos dont wanna do that ).
I need to know what would be the right motor for it a 1400kv , 2800kv , 3300kv or something else ?? Estimated plane weight near about 650g-700g i dont want to use more than 4s lipo on it , can someone help me the EDF UNIT: http://www.hobbyking.com/hobbyking/store/__11164__EDF_Ducted_Fan_Unit_6Blade_2_75inch_70mm.html my plane design would be similar to the attached pic ( similar not exact , just reference ) Title: Re: which Brushless Motor for 70mm EDF ? Post by: Sahevaan on March 24, 2012, 06:29:38 PM A first plane should be more of a high wing trainer rather than an EDF jet . EDF's are very tricky to fly , I suggest you try building a trainer model instead .

Post by: RC_DUDE on March 24, 2012, 06:39:29 PM no no im not gonna fly it i just want to build it , i hv a friend he is an excellent flyer he will fly it , he has many trainer planes ( bought from Art-Tech ) , currently i m flying his slowstick , im just a rookie at flying :D
i just want my plane to be crash proof ( seen many ppl break there propellers on landing ) , in EDF the roter and propeller is on safe side as it is covered . Title: Re: which Brushless Motor for 70mm EDF ? Post by: kplkum on March 24, 2012, 06:48:01 PM i have edf motor 4600kv from hobbyking.
