Change from RV-12 to RV-12iS During Build

I have an RV-12 tail kit that is mostly done and an RV-12 wing kit that is still in boxes. What might be involved in upgrading these kits to RV-12iS and finishing the build as an RV-12iS?
 
You’re asking at the right point in the build. There are no differences in the wings and just a modification to the tail cone. I had to make this modification myself because even though I started with the iS kit, Van’s was still working through the older tail cone inventory so us earlier builders had to modify it ourselves. This opening allows access to the fuel drain below the fuel pumps.

Ditto what Bob Y said. I have an older tail kit and the factory told me it would be fine to use with an iS fuselage.
 
old tail kit

add me to that list as well- my tail is from 2009 and will be finished as an RV-12iS
 
The RV-12 tail and wing kits are compatible with the RV-12iS fuselage and finish kits. They are actually the same kits. There have been a few relatively smaller changes to the tail and wing kits over the years, so depending on when your parts were originally made there may be some minor differences, but that should not affect ability to use for a 12iS.

Our tech support team can, of course, answer specific questions.
 
Call Van's and ask them what has been added to this kit between the time it shipped and today. Include those additions in your build. Van's only offers the RV-12iS wing kit as this kit is the same for 12s and iSs.
