years ago I tackled the HE-111 and JU-88 and it was 1/64th which was as big as one could get.
I had to do a lot of work but I loved the simplicity and they looked pretty good once I finished.
NOW my son is in the hobby and to get him started I had him build the remaining HE-111's and JU-88's as well as a 1/72nd HE-100 . It helped him get the confidence he needed to get going and I got them for just a couple $'s so no heart attacks if he messed up
