RE: Which 30cc engine and airframe?
I am finishing my first 30cc gasser and decided on a wildhare babyedge 540.its set up for a dle30 but you could just as easily install a sysassa 30..these are the top 2 choices for 30cc.just a matter of your budget and preference.the plane is on a par with aeroworks 30cc .both are about 10 to 10.5 pounds and come complete.both are great quality.
I also looked long and hard at goldwing rc.price is good at 300.a friend bought the 50cc and it not only looked awesome flying was great.
