The fairings for the other RV models run $375 for the mains and $140 for the nose so just over $500 in total. They look to be pretty similar in design so it seems this would be a reasonable guesstimate for the cost- I am betting on something around $600!
The wheel pants kit is now available for $685 + shipping.
If you have a flying -12 you can order them now. If you can wait a little while please let the guys that are flying / very near painting have the 1st crack at them until the back log is filled.
