Default Visionaire Motor

Does anyone know where to find the specs for the E-Flite BL10 motor used in the Visionaire?

I am really curious what is so special about it. I have looked at specs on many 10-sized electric brush less, and none of them are even close to being able power the Visionaire 3D plane. Non even list a 12 inch prop to be used. I just cannot see how this 10 sized motor can generate enough thrust to meet or exceed a 1:1 thrust to weight ration.

FWIW the Visionaire gross take off weight is 44 ounces. Based in that alone tells me the smallest motor that can be used is a 15 size motor capable of 450 watt input @ 3S.

Here you go: http://www.hobbyking.com/hobbyking/s...er_1200kv.html

As usual with Hobbyking the specs dont make sense as they say 51A max at 11.1v which according to my math = 566W, yet the power limit they quote as 375W

Then to further confuse they list a 11x5.5 prop which they say draws 53A at 11.1v (588W) A 12x4 should pull about the same amps.

That's Hobbyking specs for you, but from personal experience you would be perfectly ok with a 1200Kv 140g motor on 3s and with a 10", or even a very fine pitch 12" prop... In fact I built just such a set up last weekend for a flying buddy using this motor: http://www.hobbyking.com/hobbyking/s...ner_Motor.html With a 10x7 APC and a 3s battery it pulled 54A and 600W... enough to send the model it was attached to (Flyzone Sensei trainer) like a scalded cat vertically up for ever! A 10x5" prop was a better match for the model to be honest.

If you wanted to go with a 12x6 then a lower Kv would be in order: http://www.hobbyking.com/hobbyking/s...er_1100kv.html
