Just finished an Astro Hog, yet to fly due to winter weather, and I enjoyed the build so much that I would like to build the Hog-Bipe next. Not a very easy kit to find to purchase and the price is all over the place. I have already purchased a Magnum 91 4 stroke for the Hog-Bipe, this size seems to be the choice. I have an st 61 in the Astro Hog and can't wait to go fly her. The Hog-Bipe will be a natural progression I would think. Would you agree?
