Upgrade Orders

Upgrades For Previous Customers

These products are offered ONLY to previous customers who purchased products (such as plans) in the past and wish to upgrade their previous purchase to a more complete version (such as semi-kits and kits). 

Important: In order for these purchases to be honored Mud Duck Aviation must verify that you did, in fact, purchase the required item from us before we will honor these sales.  If you placed your order and paid through The Mud Duck Store (this website), the records will be available immediately as long as you are placing this order under the same account, therefore you shouldn't need to provide any additional information.  If you purchased your original product from MDA via email or a mailed letter/payment please provide additional information including (if available): forward a copy of an original email with your correspondence with us, the date you placed the order (or the closest estimate), and the name/address it was sold to/shipped to.  We apologize for the extra hoops to jump through but this is an exercise to prevent unauthorized copying of MDA plans which is a violation  intellectual property and copyright laws.  MDA reserves the right to decline any orders to customers not providing proof that they properly purchased original products from MDA.
