SIG ARF Extra 300XS, any comments?
Three: Yes, the gear should be the same and it most definitely appears to be stiff but sure has some unexpected spring on the landings. Are you flying off a grass or paved runway? Also, as mentioned before... those wheels have GOT to go... ha, ha! Already replaced the tailwheel but still have to pick up some for the main. That foam is hardly a match for the pavement.
