MPII 80/90Yup!! I'm using a MPII 80/90 on my OS 70 SZH.
All installed in an XL Fury, only just started to run the motor in but so far very impressed with both the motor and the heli.
I chose the MPII after talking to the OS 70 users and to Curtis himself about the exhasut choices for the OS 70 and most were using the MPII. The main thing people were saying is that the 60 size mufflers were choking the OS 70 causing running running problems but those who were running the MPII were saying it was a not a perfect match just as Ben-T-Spindle has mentioned but it was the best choice available.
Depending on how it performs once broke in i may just keep the MPII 80/90 fitting but i may change to the MPII 70 once it is released. I have spoke to Curtis about the development of the MPII 70 and he mentioned that because people are having very good success with the MPII 80/90 on the OS 70's that the development keeps getting pushed back to make way for the 30/50 MPII's.
I think go with the MPII 80/90, i am pleased as punch with mine!
