RE: Extreme Flight 110" 100cc Yak 54 Build!
It's crazy how big of a difference a prop can make. I'm surprised but at this point I like a 25x12s Three blade the best on my Yak. It doesn't have the blast out from a hover that the 28x10 does. I've been very comfortable with the three blade 3Ding and it slows down very good. It just has a smooth, locked in feeling.
I would be interested to hear how your plane does with a Mej 27x10. I would think that ZDZ 100 should be able to swing it.
