Me and my dad have identical biplanes, one is electric and the other ys...

When its calm, my 4150gram electric biplane is amazing. Its powered my a neu inrunner (cant remmember the specs) and Iuse hobby king 5000batteries.

When it gets windier, my dads ys 175cdi powered biplane is a breeze to fly. Its alsovery goodwhen its calm.

So my conclusion is, is that ys is better, especially the new 175, which has 150 flights so far and is incredibly reliable. In calm conditions, the electric biplane is just 1% better. The elctric biplane was just an experiment, but when we make our composite biplane for next year I'll have mine run a ys.I'm missing the ys growl when I'm flying my electric...</p>
