Hi Cuban,

The Wild Card builds really easily. They're designed to fly not 'arrive', so any 'strengthening' will just add weight. Make the decision based on how good your landings generally are! Keep all slop out of the linkages as flutter on fun flys can rip off control surfaces. Avoid taxiing with full up elevator on long grass/rough fields, as it's easy to catch the elevator ends! With a good 46/53, use the APC 12.25 x 3.75 prop. Keep the undercarriage bent down as it needs some 'angle of attack' to get airborne smoothly.

I can look up my control throws/exponential settings if this is of help.
