Why not a Magister. A long thread here:

Maybe a BladeXL...? Small throws and it is as kind as a trainer. I have reviewed it, but you propably can`t read the text I think... Take a look at the pictures:

I fly both BladeXL and Magister with Hyperion 3025-10, on 3S LiPo it will work in the Magister but I run both on 4S4000... Then I use my Magister as a TUG!
