I have a ZDZ 50 on mine. I love it !! The ZDZ has great throttle rsponse. The DA wich my freind has the same plane with the DA runs well also just doesnt have the throttle reponse of the ZDZ.

If i was to do over again i would defentaly buy another ZDZ. The biggest thing i would say is watch your wieght. The plane will get heavy fast and it doesnt harrier very well if it is heavy.

As stated above in that magazine article harrier was better with the moki but even the guy in the article said he would rather have the gas cause it provided more power !
