Some glow powered trainers with UK availability. I do not know if this is a good dealer; I saw refereence to them years ago and saved the bookmark

Some of these are available in the USA, some are not. Even though RCU has members worldwide, the majority of posts I see come from the US so info about some of these models will have to come from other sources.

One reason there's not a lot of info about which trainer is 'best' is because it is so subjective. Many people think the trainer they learned with is best even if they have flown lots of others since then.

Since you already have some flying experience, I would choose;
any trainer with semi-symmetrical airfoil, or a sport plane such as
ARF http://www.sussex-model-centre.co.uk...d.asp?id=25446 or the 40 size if available
ARF http://www.sussex-model-centre.co.uk...xd.asp?id=2216
KIT http://www.sussex-model-centre.co.uk...d.asp?id=21604 or the 60 size

With an instructor to help you I think any of these would work well to get you flying again.
