As far as legal is consirned having weighed a bunch of Super Cubs over the years , all rigged up in their Alaskan dress clothes with heavy gear , big tires , and borer prop, most of them actually weighed around 1170- 1225............. on certified digital scales; 95% of the owners always had an amended weight and balance, that showed something in the thousand pound area............... of course many Cubs now have the 2000lb GW increase done on them nowadays; to grab the extra 250lbs, for 135 operations, So I guess if you are still calling the GW 1750, then you got about a 550 useful , so legally you could carry two 250lb people and 50 lbs of gas.. what do the really carry ????
One of our strips we guided off for years on the Chilchitna Stream, off the Mulchatna River, was on a ridge and had about 700ft to where the tundra was too rough to use, We used to call a "good load" for a 150hp everyday SC, One complete Bull Moose , thats all four quarters , the antlers tied on the wing struts , and the headskin thrown in on top of the meat............. try it off a 700ft strip sometime, when you feel, like your getting really catty with your airplane. Our strip dropped off about a 100 ft into the alders; so there was no aborting the takeoff it was all or none.
I have always figured the cub is "the airplane" for hauling huge loads out of super small places, the wing has fantastic lift at slow airspeeds, that is really not debatable. Could I haul a whole moose off that same strip , with a 7/8 GCBC ???
Rigged up the same way as the Cub, with big tires and long flat prop, vgs, yes you can , would it take off in the exact same spot , probably NOT, is it possible I might have to leave the cape or horns , yes it is possible, But like I have said many times here, it is not a Super Cub , but its a hell of a lot closer than lots of folks think it is! After both airplanes break ground; would it climb with the 18? yes it will and then some, is it more comfortable to fly all day? , yes it is , will it pass it in the air like it is tied? , yes it will, which one would I prefer to fly a thousand miles a day? , no comparison. So everything is a compromise in flying , if the Only thing you want to talk about is; who is going to take off the shortest, that answer is always going to be the same ..................... Huges 500D model,it will easily whip any Cub I ever saw.................
