I bought a TT Pro 46 thinking I would get a LT-40 ARF to go with it for my first plane, especially since the LT-40 has a larger wing (more visible) for a 40 size plane. Turns out you can't find the ARFs anywhere, and SIG has no idea on when they will be offering any model of ARF kits again (per their email to me), and I'm not sure I want to build a regular LT-40 kit. So, just so I know all of my ARF options, will the TT Pro 46 work okay with a 60 sized trainer without being underpowered, or do I really need to stick to 40 sized trainers with this engine?
