Thanks for the great reply,
I wonder why accident rates were higher in the L-2's and L-3's, which called for them to be replaced by the piper L-4's ? I was always under the impression flying a L-2 vs L-4 are very very comparable ?
The previous designs for the cub (L-4) was all Taylor (of later Taylorcraft) and side by side comparison of the L-2 vs L-4, they look almost identical.
The L-2 has a semi symmetrical airfoil that is faster than either the L-3 or L-4 but is no good for short field work and it does not "telegraph" an impending stall as well as the L-3 and L-4. In addition it will spin more readily that either the L-3 or L-4.
The majority of the L-2 accidents happened while turning from base to final at minimum airspeed. A stall in a L-2 at minimum speed with any rudder or aileron deflection will result in a pretty quick and very nice spin. I loved that about my L-2A it spun better than any of my other L-Birds. You just cannot slow it down like you can an L-4 in order to get in to a short field. The spoilers on the L-2M did help a little as the aircraft could be flown faster up till short final then deployed to sink fast in to the short field. However the spoilers did not help the dismal take off and climb performance due to the weight and wing.
The L-2 best rate of climb comes 10 mph higher than a L-4 which means you are eating up available runway to an obstacle at a much greater rate than an L-4. L-2 aircraft are scarce as not many were ordered and a large number were destroyed in accidents.
One final note, the wings are all wood including the ailerons and when I parked mine at air shows if it rained and the wood ailerons absorbed a lot of moisture they would bind until dried out.
I did like the faster cruise 8 to 10 mph than the L-4 and the roomy cockpit.
The L-3 had a low accident rate but was too heavy compared to the L-4. The only Aeronca that compared in performance to the L-4 was the O-58A it is 50 to 75 lbs lighter than the later L-3B.
You just cannot beat a Cub for shortfield work, the L-2 and L-3 would not even come close.
