I have an 88 FC w/ TO4B and FMIC. I plan on going to 3rotor when the current S5 motor goes bad.

So should I get the LTX12 and will it be compatible w/ current setup?

How much more does the 12 cost? It sounds like there are options on the coils too. What's the best route to go?

 

If you get the 12 you can use it on your 13b and your 20b with only cyl number changes (asuming you are using the 13b cas on the 20b)

PM me for pricing.,
