Aircraft Sub-Kits

More flexibility and options for construction

Build Your Kits in Stages!

Sonex_ST_0788_Cut-Away_250.jpgSonex Aircraft is pleased to offer Sub-Kits! These Sub-Kits are designed to give Sonex Aircraft builders more flexibility and options for constructing the already industry-leading Sonex Aircraft kit values. If you’re looking for a way to spread the cost of building a Sonex Aircraft over-time, Sub-Kits are a great way to build without obtaining financing. Once this building path is selected, the builder may purchase Sub-Kits at their own pace of construction and spread out the project investment over the life of the project.

Note: Sub-Kits may be purchaed in any sequence for most aircraft models. Purchasing multiple Sub-Kits in one order will reduce crating and shipping costs for your project.
