Another advantage I can see to this build is, with the fan-stick-fan bike it's almost impossible to get it perfectly straight. Mine always seem to veer off slightly, whereas with this triangular design I imagine it mitigates the drift?
I highly recommend [](this video), to help with building a straight one. Bit of a pain, but I can fly in a straight line while looking at my phone now!
Thanks, I'll give it a watch! My current 'best' attempt lists badly to the left haha. Oh, it seems there's no link, did something go awry with your formatting?
