I just finished my long awaited Astro Hog, I have wanted one since the early 80s. I built it as a tricycle gear and if I had it to do over I would have gone tail dragger. I also took half of the dihedral out of it and went with dual aileron servos as I just dont like the torque tubes.I am running a Saito 80 on my Astro and it is just the right amount of power although a .91 4 stroke would be fun also. I could see where 2 degrees right thrust would be nice but the down thrust is not needed. I really love flying my Astro Hog!!!! it is just a joy all the way around and it was a fun build as well. I didnt use the supplied turtle deck and opted to carve one out of Balsa as I didnt want to find matching paint for it. I hope you enjoy building and flying your Hog as much as I have!!!
