At a decent altitude(below 3000ft!) The DA turns A 22x10 or 24x8 with authority. On a 16-17lb plane you can expect to hover in the 35-50% range. I was hovering my 19# edge at just over 1/2 with the DA and it still was'nt broken in yet. The DA and 16-17# plane is a perfect combo. Extreme Flight is making this the perfect match on his planes. All are 85-87", 16-17#.
Most 50cc motors will do here. The BME and 3W are also excellent choices. I personally dont care for the ZDZ brand. Their twins are lacking. I guess most go for the ZDZ because of price and they do run good but...
The DA is about a pound lighter than the ZDZ. Another reason to go DA is servicability. Desert Aircraft is the best at customer service( when you can get thru...the phone is always busy ).
