hi i wanted to know if there is a downside to using an N2 recone on a ufo btl, because i have a friend with 2 recones and have no use for them and i needed recone. would they work? 

no one?

Doubtful. The N2's have different motors, well different magnets all together than the ufo's.

they'll drop in..but the set up height is way off the coil will not be centered

i figured they would dropped in because the baskets are the same as, but was unsure of what happens in the gap. but thanks for the response.
