RE: Sig Astro Hog "Engine recomendations
The last Hog I built had an OS .91 4C in it and performed nicely. Just for fun I set it up the same way I set up pattern planes using wing mounted aileron servos as suggested. I also put an elevator servo in the back, pull-pull rudder and mechanical retracts. If you think a Hog looks good as a taildragger you should see it with the wheels up. Wow!! I do strongly reccomend cutting the dihedral in half. It looks better to me and will roll much better. Whatever you do it will be a good plane.
