I'm getting a BME 30% Yak in a few weeks. What engine should I use? I was thinking DA50 or MVVS 45cc.
I've heard that the DA50 "burbles"?? I 've heard the engine and I must agree that it seems to make a missing sound or a burble sometimes. But I also hear that they (Desert Aircraft) has the best service. But i can't find any in stock. DA says 3 to 4 week wait.

I've also heard of nothing but good things about the Mvvs. Powerful, reliable, light weight. In stock available for immediate shipment.

I need sojme advice from people that have experience with these engines.

Thanks in advance
Mike
