RE: 140+ mph H9 Sundowner 50 Arf
Someone flew a Sundowner today with a Jett .90 LX he tried 11x8 and 10x10 and man I can tell you the YS 91 heli engine blows it out the water. I really wanted to try that combo but after seeing that plane fly man it was a dog. Even the YS1.10 warbirds where passing that thing. The engine sounds really good but i guess i was expecting much more.
