Gear Door Mod

[aldoradave]

I am looking at an alternate 73 P337 and the seller is touting that his has the gear door mod ( I think that means removed doors) and Horton leading edge STOL.

My guess is that the door mod might reduce cruise speed some and have no idea about the Horton STOL.

Could someone comment on these and their relative worth?

Thanks a bunch,
