scorpion 4020-1320

this is the 3rd 4020-1320 motor I've bought. The first 2 were for my Synergy 516's. I bought this for my mini version XL Power Nimbus 550. I wanted to build it as a light weight 550. This motor has plenty of power on my 516's, even as stretched 550's, so I imagine it will keep up just fine on the nimbus 550! I've also used this 4020-1320 on my oxy 5 with mini servo's, it was very responsive also.
