That is very interesting Gomer. Will you get the additional 300 pounds lift capacity that the L4 has over the L3, effectively?
Then, if you really wanna go hog-wild, there is also apparently a Service Instruction to turn both an L-1 and L-3 into an L-4 (BHT-206-SI-2052) with a 4450 internal gross weight
I believe this conversion is so expensive that it makes no economic sense to convert to an L4. Does anyone know of a conversion that has happened and the costs to the operator?
