The stuff I use is designed for applying lettering, fleet numbers, DOT numbers, etc to trucks and buses so it may just be a different type of process with different materials. I do have to be careful with it when peeling off the transfer paper as it pulls hard on the covering. It's stronger than I'd like when covering over a balsa structure, but as long as I'm careful it works well.
The fuselage and tail lettering was cut and prepped this morning, so the vinyl is done and ready to install. The plan is to finish the construction by Friday night, and then start covering on Saturday. The electronics also need a little work still, such as installing a battery voltage sensor, setting up a BEC for the receiver, etc. A battery tray needs to be installed and magnetic latches for the battery access door need to be fabricated. A little trim work is also needed, windscreens should be added for a proper look, etc.
All small projects that can be done fairly quickly, and some stuff will probably wait until after the maiden.
The only big project left is making the cowl. I've got some ideas on how I want to do it, but will hold off on it for now unless the weather is bad this weekend, then I may just get it done instead of going flying.
