RE: MVVS 45 ignition bad?????
OK,
The ICU-L (for lite) is the same as MSR-L, and is the ignition on the latest engines. I just was not sure wether Horizon had the -L version or the -S version on the 26 and 35 engines.
These ignitions will cease to operate bolow 6.4V, that is why 2S LiPo or equivalent 6xNiMH voltage is needed.
