RE: Road Runner Arf
I wrote a Product Review on it for R/C REPORT and it will be published later this year.
Negatives: 90" one piece wing, looks like an Ugly Stick, expensive, looks like an Ugly Stick
Positives: gentle flying or mildly aerobatic, very wide range of engine choices, quick assembly, everything fits.
It can be used as an engine or radio system test plane, drop candy, tow gliders, take the neighbor's cat for "part of a ride", etc
Cut the price about 75 bucks and make a 2 piece wing, and they'll have something there.
