The new Crack Pitts evolved from a very extensive design effort which started with the same formula and design concepts that created Chris Jewett's renowned Crack Yak. It then added RC Factory's extensive experience with F3P biplane design and production, and topped it off with Twisted Hobbys team member and design engineer Cody Wojcik refining the flight envelope and fine tuning the air-frame to achieve an incredibly precise yet extremely capable aircraft that we are positive is the absolute best small EPP biplane on the planet! In the Crack lineup, the Crack Pitts is the smooth, calm and stable aerobatic master to the Crack Yak's high functioning insanity, with the Extra Slick offering a feeling more similar to a smaller balsa 3D airplane. In comparing the Crack Pitts to the Crack Yak many have said the Pitts can feel like a Crack Yak in slow motion.
Designed from the outset to enhance preciseness, the enormous ailerons of the Crack Pitts provide a brisk roll rate when you want it. The generous side area in the air frame means that directional stability is enhanced and KE flight requires very little rudder. Knife edge loops are extremely tight and coupling is zero! In addition to its exceptional flight qualities it will become a legend in learning tool durability and fly-it-anywhere usability. The Crack Pitts is truly at home anywhere from the gym, to the front yard and all the way to the flying club!
Keeping true to Twisted Hobbys exceptional level of prefabrication, you will find all control surfaces are pre-hinged, with laser cut control horns, high quality printing, unique rigid yet light weight EPP construction design, adjustable end links for ease of fine tuning and all hardware needed to construct each model. In addition to what you have come to expect from Twisted Hobbys quality, you will find new construction methods for biplane rigidity resulting in an extremely clean looking final aircraft without any need for external bracing and vastly improved durability over other EPP biplanes.

I'm not a 3d pilot, I'm not really even any good at level flight, but on its maiden, I was able to (poorly) execute a few 3d moves. It flies into a hover almost effortlessly, and although I cannot yet keep it there, I can barely believe it. It flies smoothly and has plenty of control surface(s). I know that I'll really be able to sharpen some 3d skills flying it, even more so than with the Durafly Hyperbipe I am replacing with this model. I'm a happy customer!
This was my first TH plane and still my fav even though I dropped a star. The fuse to rudder joint was not cut right yielding ~7 degree angle on this joint and one of the SFGs had an extra cutout in it for some reason. I have not seen this in any of my other TH kits so I'm calling it a defective kit that I didn't catch before starting the build.
This is my favorite TH plane even though it has some asymmetry in the yaw coupling (rudder joint?). It is very predictable in the air and is an absolute tank of a plane. I've beat the crap out of this plane and it still flies just like new. On one flight I hit a light pole, bounced off and kept flying. Once landed it had torn wings (to the spar!), chipped prop and a cracked fuse - but it still flew just fine! If you want to learn 3D this plane is an excellent choice!
TH digital power combo
Batt: 2s 950mah nano Tech (10-15 min flights so I can learn)
note: This batt is only 8gr heaver than a 450mah regular lipo
The Crack Pitts ( along with the Crack Camel ) are two of my favorite planes to fly. I purchased this Crack Pitts as a replacement for my current identical Crack Pitts because I have flown the original so much ( multiple seasons) that it is getting somewhat tired and sun faded and I do not wish to be without one. Excellent flight characteristics and very enjoyable to fly. No bad habits! An excellent way to practice your 3D.
This is my 2nd one. First one is going strong, thought I'd get another airframe to replace it with when it eventually gives out. Fantastic plane for flying around the front yard area. Slows up really nice, and great 3D. Very durable EPP, only design complaint is the landing gear mounting to the fuselage is a bit weak on a crash, it can tear the EPP foam out of the lower fuselage where the gear attaches. Easy to fix with Welders to glue the foam chunk back in. The other option is to not crash, but this thing is so much fun to push your flight envelope past where you're used to! On the next build, might try to reinforce the area with a few square inches of thin plywood on both sides. My current power combo is a HK2612 S-line 1900kV with a 8040 prop, using a 2S 800mAh battery. Great flight times, and good power, with >13 oz thrust (measured, static). Plane is a little over 8 oz. Might try a 9x5 prop and see if it gets a bit more 'pop' accelerating up from vertical hover, and more propwash over the control surfaces for manuevers
Built this a few months ago - went cheap and fitted it with servos, 55g Hextronik 25D-28 brushless outrunner, Hyperion 20A ESC, Orange receiver, Grish 9 x 6 sport propeller and E-Flite 1300mAh 3S batteries, all from the junk box - ended up weighing nearly 400g all up (twice the specification!). Forecast to fly like brick but does not - am new to 3D but can hover and harrier land with little effort, nice vertical climb at full throttle, all on "sport" rates - weak spot just forward of aileron servo needed reinforcing with tape and had to fit wire tail skid to stop rudder hitting the ground - otherwise no complaints - now my favourite plane!
By far one of the best small 3D planes on the market! Flies incredibly slow, and is so light it would make a great trainer as well. Because of the low mass, most crashes have little or no damage. Some say there a little pricy, but the engineering and unique stiffer EPP foam make it worth while.
Good kit, good instructions, good build
Welders glue worked well.
I gave this a 4 stars since i've never built or flown a EPP model before. Instructions were good though I wasn't sure which glue to use so i used welders over beacon, next time i will use beacon glue. Flight times are shorter then i hoped. Enjoy the way it looks in the air, thinking of getting the smaller size next.
