Low and Slows stats are perfect ,This motor is great with a tractor prop .but the armature only has a fiber insulating washer as a thurst bearing .so as a pusher (ZAGI) it burns up the washer and shorts out the arm.so if you get it for 29.99 what the heck .these opinions have been formulated under extensive testing as the picture of all my burnt supers shows... though by tripleing the phenolic washer or installing a thrust bearing i have quit toasting these little cheap powerhouses.
