Product Description
Meet the PittsBull! Inspired by the full-scale Pitts Model 12, the 30-inch Hacker Models PittsBull was purpose-built for extreme 3D and freestyle performance rather than scale flight. Its lightweight biplane design combines exceptional maneuverability with the durability needed for regular indoor and outdoor aerobatic flying.
Large control surfaces, dual aileron servos, and a full-flying elevator with up to 90 degrees of movement provide outstanding control authority. The PittsBull excels at axial rolls, rolling circles, torque rolls, hovering, tumbles, and other aggressive aerobatics while remaining surprisingly controlled at slower speeds.

This plane is sick!
Took a little while to get together but wasn't too hard. A fun satisfying build. This plane flies amazing. It's phenomenal on high rates. Nearly 90 degree throws. It'll do whatever you want and stop on a dime. I was worried it would be twitchy and hard to control. Not at all. I started low rates then quickly realized high rates should be no worry. It's extremely maneuverable and precise. It's well capable beyond my skills and I don't foresee ever getting bored with it.

HM 30" EPP PITTSBULL 4.5 *
I personally am not a fan of EPP and much prefer depron for 3D/Freestyle indoor gymnasium flight. However I understand the move by almost all manufacturers to EPP. Its flexible and withstands more crashes then the average pilots skills usually has in a gym. Therefore he is happier with the product. That being said because EPP is flexible it usually does not fly as well as the stiffer lighter depron, although it is more crash resistant as noted above. In the quest to make EPP lighter, thinner 3/4 mm stock is being used as opposed to originally being built out of 6mm EPP stock. To stiffen the thinner 3MM EPP more carbon fiber rod supports are needed to keep the plane from being TOO flexible in flight. So this is the tradeoff. This plane is no exception. That being said for an EPP plane (especially a bi-plane) it flies very well. The Elevator build is slightly complicated but superior to other manufacturers end results. The plane flies well, this is a Freestyle tumbler, not a F3P flier. It wants to do axial rolls and rolling circles, it wants to torque roll without the pilot barely trying. What this adds up to is a very fun (mostly indoor) airplane that can take a little beating on the fuselage since its EPP, although you might be re-glueing some struts if you are of intermediate flying skills. All in all I really like this plane, its so much fun to fly. It likes to fly fast, but can fly slow when needed, thanks to the Elevator throws and relative low AUW weight. There are videobuild instructions on youtube, which I found very helpful. The manual pictures are black and white and too small, this is a slower, complex build but not overly complicated. I highly recommend this plane for average toadvanced 3D pilots.

HM 30" EPP PITTSBULL (IN-DOOR) RED
I have had over a dozen 3D profile foamies and flown many others. This little plane out performs all the rest. The massive control surfaces and high thrust of the little motor on 3S results in instant response to stick and throttle inputs. Tons of fun to fly!!!
