RE: 88" EF yak or 86" QQ yak?
I owned the Aeroworks Yak and flew 200 flights. Good airplane with good flight characteristics. I now own the 88" EF Yak and it is not a "good" airplane. It is a "SUPERB" airplane! I have 200 flight on the EF. It is significantly bigger and flies much lighter. I am now finishing up the 110" EF Yak. Should fly that this week and expect it to be even better. I don't see how you can go wrong with either the QQ Yak or the EF Yak. I will say, the EF Yak looks great and the huge cowl absolutely swallows the DA50 with no cowl cutting. Love it!
