I've have this model, managed to get it airborne only once and had the firewall, fail on the maiden flight.
I would say that it appears to be a good flyer, but it has weaknesses eg firewall. Has a high propensity to nose over at the recommended balance point taxiing on grass, and on take-off .
If using factory mechanical retracts, they cannot be fixed all the way forward on the mounts, otherwise the wheels don't fully fit retracted into the wheel wells, and also interfere with the retract servo. Result, an even higher propensity to nose over.
I prefer electric, but not many choices for a model this size.
