I have a Ladybug(original kit version of the baby bee) which was originally powered by a Cox .020 and now wears a small outrunner b/l on its nose. It is very nimble for a rudder/elevator ship and can do some aerobatics I've not been able to replicate with other planes. It does have some handling quirks due to being so short coupled--ie, it tends to "tuck" at high speeds and gets VERY pitch sensitive at high speed, but it's very fun to fly. A good friend has had a few versions of the regular lazy bee in the past; he loves them and reports they fly similar to my ladybug.
