Racerstar BR2208 1400kv


Got me another budget motor from Banggood ..
Wont bother with a link since no one is interested in anyway ...

The only prop I had on hand to try was a 8045 ( 8 x 4.5 ) Electric Prop ..

2s Battery ( 2200mAh )

7100 RPM @ 9.6 amp

3s Battery ( 2200mAh )

9150 RPM @ 15.5 amp


Even though there was not a huge RPM difference between the 2s and 3s , one really could feel the thrust difference . I cant help but feel that this motor would wind out some once the motor was in a plane and moving forward . On the 2s battery the motor remained completely cool to the touch and on the 3s battery it became lukewarm . So the motor did notice the load under the 3s battery , but not overly so . Especially considering that the recommended prop is a 8 x 4 on 3s .

I would say that this motor would be very happy on a 2s battery and a 8045 prop ( I like the peak current draw ) . I would be very tempted to even try a 9x4 prop with a 2s battery to see how the motor handles it .

Soldering Day :

Lots of things needed soldering , and with the wind blowing rather hard outside the soldering iron got a work out .
The R4 needs a Rx , so I had to solder the pins to one of the FS2A Rx I keep handy . Also needed to do a battery lead .
Also have several projects that need doing ..

GT Power Tachometer

Goodness me ! I love and hate these !
I love that they do multi blades , the Tach is relatively cheap .
Butt! , I really hate the button batteries .
These tacho's have parasitic drain . And the batteries are always flat when I need the tacho .
So I will be doing a AAA mod shortly and run it on some rechargeable AAA batteries in a external cradle .
Might have to do a thing on the mod !
