Well i ordered a 1717 the other day when this was posted and just received it..Now i know why these 1717s where in the corner of the warehouse... I got a 1717/17 1580kv with a 6mm shaft and closed endbell. which is odd because the heli version has 6mm shaft and open endbell... I'm kinda frustated at this point..
IIRC, the first batch of the car version was mistakenly made with the 6mm shaft.
