Default RE: SK3 F3A motor-same as Hacker F3A, but 29% of cost ..?



ORIGINAL: apereira
if you can not see the Turnigy Aerodrive XP SK6364-230 not being a copy of the AXI 5330 F3A, then
Hello Apereira, I have looked at these two motors.
The Turnigy Aerodrive-Xp SK 63-64 looks NOTHING like the AXI 5330/F3A. There is NO resemblance whatsoever.

http://www.electricwingman.com/model...-5330/f3a.aspx



And also the SPECS ARE COMPLETELY DIFFERENT for these 2 motors:
(The Aerodrive-Xp SK 63-64 was an "N" series motor made by the XYH factory - http://en.xingyaohua.com/html/play/430.html; its weight on the XYH website is given as 706g; -This motor has not been sold by HobbyKing for ~2 years ... )



Turnigy Aerodrive-Xp SK 63-64: 690g, Kv 230, diam 63.4mm, length 67.4mm, Shaft diam 10mm, 9 turn; Cell count 8-10S Li-Po; Glow Equivalent 1.60; Suggested Prop: 22x12 to 24x10; -"For 30% scale warbirds or 3D planes up to 100inch and anything requiring a 45cc gas engine"



AXI 5330/F3A GOLD LINE: 652g, Kv 235, diam 63mm, length 64 mm, Shaft diam 8 mm; No. of cells 10s Li-Po; Glow Equivalent 1.40; Recommended for propeller 20"x13"

It is impossible that the Turnigy Aerodrive-Xp SK 63-64 is a copy of the AXI 5330/F3A. The Turnigy motoris 40g heavier, 4mm longer, has a 10mm shaft, uses a 2" larger prop, and was NEVER intended for F3A planes (-it is much too heavy at 690g ...)
These two motors are not even close ...
