    Delivered on time and packed well. This is a great piece of kit to sort out your power train components, for best battery performance. Thrust measurement was consistent and current reading was within 50mA, when measured with high accuracy meter. I modified the carriage to take EDFs as well, Please see pictures. Very happy with purchase.

    excellent tool for rc brushless motors. very well built and intuitive. great it is machined out of aluminum stock rather than thermoformed plastic. would highly recommend unit. only drawback is chinese lettering for indicators. should send stickers on english to put over them so it will be less confusing.

    Dsd device makes a very good impression. The instructions are in Chinese and English. I could not try it yet.

    Grundsätzlich eine super Idee dieser Motorenprüfstand, aber leider hat die mechanische Fertigungsqualität Mängel: 1. Im Kugelumlauflager fehlen Kugeln, daher wackelt die Führung bzw. der ganze Schlitten! :( 2. Die Bohrungen zur Befestigung des Schlittens auf dem Axiallager sitzen falsch, dadurch sitzt das Axiallager nicht mittig unter dem Schlitten! :( Wenn ich dazu komme lade ich noch Fotos hoch! Anscheinend hat die Qualitätsprüfung geschlafen oder gar nicht stattgefunden - das geht besser!!! Die elektronischen Komponenten sind ok. English: Basically a great idea of this engine test bench, but unfortunately the mechanical manufacturing quality has deficiencies: 1. there are no balls in the recirculating ball bearing, so the guide or the whole carriage wobbles! :( 2. the bores for fixing the carriage on the axial bearing are wrong, therefore the axial bearing is not centered under the carriage! :( When I get to it I upload some photos! Apparently the quality check has slept or not taken place at all - this works better!!! The electronic components are ok.

    It isn't accurate enough for calculating thrust vs. known weight of a plane. However, it works just fine for comparative testing. i.e., different props and different batteries. The only criticism I have is the supplier should include a decal strip showing English description for the 3 buttons so the purchaser could just apply that over the Chinese characters.

    Very well made - really good craftmanship. Only one potential drawback: The user's head comes quite close to the propeller plane. For thrust readout: Can be circumvented by pressing the right button (Tare) during max. thrust. After motor stop, maximum thrust can be read out as corresponding 1:1 negative value. For electric data (voltage, current power): Better make a snapshot with a camera and read out data afterwards. Be carefulf and stay clear of the props ! !
