KDA 20-40 15

Nov 14, 2007

Runs...



I tested it with the Hextronik 018 ESC, 2s Lipo (7,4V) and a Graupner Cam Prop with 4,7 x 2,4.



Before i run it, I opened it up. Yes, this is possible, just screw two M2,5 screws into the front motor shield and turn.



The motor has only one large magnet, the filling degree of the coppercoils is good. Be shure the motor is clean inside. I had some tiny glue crumbs between the coils and the magnet. Not much, the motor will work aswell with the crumbs.



The motor pulls about 10A and have about 30.000 rpm. It gets warm, about 40 to 50 C



For the german native speakers:



Ich habe den Motor mit einer Graupner Cam Prop Klapplatte 4,7 x 2,4 getestet. hierbei lief der Motor mit 2S Konion und einem Hextronikregler 018 mit ca. 30.000 u/min bei 10A



Aufgemacht habe ich ihn auch, das geht, indem man in das vordere Lagerschild zwei M2,5 Schrauben reindreht und dann das ganze Schild runterholt. Der Fllgrad der Kupferspulen ist gut. Der Magnet ist einteilig.



Subern sollte man ihn von innen auch, ich hatte ein paar kleine Krmel Kleber zwischen Spulen und Magneten. Er funktioniert auch mit den Krmeln



Der Motor wird warm, so ca. 40 - 50C, egal, ob nun mit oder ohne LSR.

2040-15L

Nov 14, 2007

Hi all



I use this motor in a little home made styro racer on a 2s 1300mah lipo pack (also UH) turning a 4.75x4.5 APC-E prop. Plane weight is about 400grams. Motor pulls 20A peak and 18.5A continious. Performace is stunning. The plane is lighter then with a speed 400 and 7 cells and power is a lot more.



Great motor for that price. When they are out of backorder I order another 3

KDA 20-40 15L - Easy Star MPX

Nov 14, 2007

I installed this model on my EasyStar MULTIPLEX in place of the original PERMAX 400".

It is great. In combination with a 1300 mA Lipo 2 cells, it become possible to climb very fast.

The combination of superior performance and a competitive price makes these motor a great value.

I'll put another one (16L) on my easy glider Multiplex. Best to buy !
