Good to have you on board. We have some very nice L-2 (equivalent to the old Jetex 50) and L-1 type motors at the moment (have a read through this thread) suitable for a variety of built up (think old 'Flying Scale') and profile (all sheet like the Veron Quickys). So it all depends on what you want to make. What 'non-scale' models are you wanting to build? I'm sure there is a suitable modern motor for it as long as it's not too large!
One question: Where do you live? We can post motors within the UK but not to, say, the USA.
Do have a look at our 'FAQs' (and some of my old blogs and at the Jetex Store) and come back with further questions.
but whether these Rapier L-2 motors are suitable for you depends on the model ... we have only L-2's of lowish power. The TSP L-2 motors are quite powerful and can be 'bored out' to lower the thrust and increase the duration.
