Had a spectrum about a year ago. As I recall the weakness in the LG are not the blocks in the wing, but the lite ply plate that is used to simulate a retract mount with the included fixed gear. My fix was to just put real retracts in. Many hard landings and I never ripped them out. If you don't want retracts, just lock them down and run as fixed gear. At $20 for the hobbico's, it is probably as cheap as converting the fuse to fixed. Not exactly what you were asking, but it might work. HTH, Chuck
