It was a bit of a gamble with this purchase as I had no idea how to mount this Motor due to its long length and mounting holes in-between the two motors...but I decided give it a try to have something different from jets, twins, flying boats etc. In end I installed it on my DZ500 using few 5mm spacers and long screws, it just installed in a flash actually and the power is immense I was glad I gave it a shot despite the low score reviews on the similar larger and smaller BL systems here but this was just right size for the DZ500 with 2 25amp esc, changed the props to 7*5 3 blades the escs hold up nicely and power is smooth
