you could also go with a larger plane such as the Sig Kadet Senior. It flys very nice on a powerful .46
and is very large 80" wingspan. I have flown a few different trainers and this is the one I like the best.
Very easy to see and possibly one of the best trainers ever made.

But I have to say it also, some help would increase the chances of success
