RE: lt-40 prop
flycatch you bring up a pertinent point here, though in the specific case of the LT-40 with stock wheels and gear, it will accomodate an 11" and even 11½" blade without issue on grass or bitumen. If it's striking, the default gear just needs to be bent back into its original position occasionally, as it tends to spread with consecutive impact or heavy landing lowering prop clearance in continuous use.
