Morris has them for just under $400. But no muffler. The zenoah's are under $300 and include the muffler! Funny how the issue of weight will make you spend more! Afterall this is the ultra stick lite we are talking about! I guess i'm just spoiled with my DA's and 3w's being so lite. HUMMMM!!! D/a 50 on here? That would be kind of fun huh??? Ha. Ha. I have not recieved my plane yet so i have not been able to look at how easy the mods for moving the servos aft would be. I did not think it would be so terrible, Others have done it.
