After you fly a good profile such as the mojo you will forget all about that twist!

I agree they are a good bang for the buck, and prolly an excellant sport flyer but are not a serious 3D plane. There is a lot more to 3D than just haging on the prop you know!
I am sure the 625's will be ok in the mojo. They are overkill but so are the 605's! At some point I am going to build another Mojo, just for a back up. They are so easy to build I figre why not?? [8D]
