What is the difference,bravo 1 upper and bravo x (not a xr or xz) thanks.

x gears are heat treated differently, has removeable steel tower and retainer is new style( thats the easy answer)

Thanks. I have another ? The x upper has 1.5 ratio and I have a imco lower with 1.35 ratio can I use them together and would the ratio be 1.35.

sorry for the dumb ?'s I only know how too brake drives.

GOODT

the way im reading it if you have 15/19 tooth count in lower you ratio will be 1.5-1

I dont know the tooth count will have to check,I do know they are 1.35 they where hooked up to a imco xr upper. I was told that all xr uppers are 1.5 ratio. I was also told "if you take a lower off of an xr with 1.35 ratio and put it on the x upper with 1.5 ratio it would be a final ratio at the prop shaft of 1.35."
