Honestly, both options are great, either one will work, I have been flying YS for 15 years and I can't love it more, I also started flying F3A with an electric and it works very well, but I still like the sound, the smoke and the low end torque of my YS engines.

So saying the IC engines will disappear is a very bold statement as it just undermines what other people think or like, I personally do not plan to quit flying YS no matter what, the electric is missing something for me still.
