Biplane
I'm going along with the last 2 posts. The Hog Bipe is a great flyer and forgiving.
Now, for a given engine size, the buipe will be a smaller plane, wingspanwise, and look smaller in the sky. Also, you will not want to try to stretch it out in case of a dead stick. With a bipe in this case, you will put in some down to keep your speed up to avoid a snap.
Overall, the Hog Bipe is a good plane to have in your stable - been flying one about 4 years now - stuck a Magnum .91 4-stroke in the nose and has plenty of power. The newer 4-stroke 70's should do well also, from what I have seen lately at the field.
Take care and I hope that this info is of some help.
