I have nothing but the highest regard for Bushwheel products, I have 31"s and a Babybush on the Cub, and have a set of 29"s for the 180, would you still run the Babybush on a '79 with 3190lb. gross?

Do you really think you're putting that much load on the tail with the 1400# useful load? I'd venture to say that if you did the calculations you'd find the tail weight is much less than you think it is, otherwise the tailwheel would be putting a groove in the asphalt on a hot day.

StewartB said:Do I think it's that heavy? Yes I do. CG calculations are for in-flight loads, not 3-point.
Well, obviously; all of the cabin is behind the mains, so the load would *have* to be behind the mains. Regardless, what I said earlier is true, in order for 1400 lb to add 800 lb of load to the tailwheel, it would be necessary to load the entire 1400 lb *more* than 10 ft aft of the mains. It's simple math, weight and arms, no magic and nothing changes much because you're on the ground. The aft baggage compartment in a 185 (and I'm assuming a late model 180 is similar) is a little over 8 ft aft of the mains, so unless you have an extended baggage and the entire 1400 lb is lead ingots loaded in the extended baggage, you won't ever add 800 lb to the tailwheel load.StewartB said:Of my 1400# useful load virtually all of it is loaded beind the mains while in 3-point.
StewartB said:If my tail weight does only come out to 700#....that's still more than 500.
StewartB said:Is it reasonable to assume the tail weight at gross is at or below 500#? It sure doesn't seem likely, does it?
StewartB said:I'm done hypothesizing. I'm going to find out. I've got a few calls out looking for the scale. I figure I'll put 200# of fuel in the plane and borrow 20 sand bags for my little test, which I'm definitely intending to do. I'll let y'all know what I find. I'll start with the pilot seat, both front seats, add passengers, and finish with the balance in baggage until I'm at full gross and within CG.
I'm pretty sure what I'll find, but then I've unloaded my plane a few times to facilitate lifting the tail to change the tire. If I'm wrong, I'll fess up to that, too. Hypothesize, experiment, validate. I think that's called science. Everything else is just talk.
