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.

Again I'm impressed by the detail-oriented design, the fit and finish of all parts. Went together as expected, looks sharp. I enforced the carbon gear struts against the lower wing by cutting and epoxying bamboo sticks in flight direction into the leading edge.
This is a durable easy to build plane. I live in Montana so right now I'm flying it indoors. I've always been partial to biplanes so for me this is a winner. I've been flying the Click for two seasons now and I'm guessing it will not get flown nearly as much now that I have the Pitts. Great job.
This was my 4th TH plane, and I am yet again very pleased with it. Great design, excellent material quality, good instructions, and easy build, and a great flying plane.
With a TH 1450KV motor, 600 mah 3S battery, and landing gear (with larger, ultralight wheels), mine came out to 8 oz even. I used a moderate amount of Welder glue on it, adding a little more for reinforcement where I though necessary. I did not attach the side force generators, because I don't fly only 3D, and they make any plane fly funky in regular flight, plus this plane does no need them at all. Knife edge flight requires virtually no rudder. Hovering is very stable, and almost effortless.
Unfortunately, I couldn't do my maiden flights in zero wind and evaluate the flight characteristics. Lightweight small foam planes do not like wind, and they fly pretty unpredictably in even 5 mph wind. They shine when the wind is dead calm, and I look forward to putting this plane through its paces if I can ever get that kind of weather. I find that this plane, along with every other similar plane (except for the TH F-22), "hunts" for a heading (in all 3 axes) in wind.
Control authority is excellent, and it does flies very slowly quite well.
Another winner, and TH planes are all I buy anymore.
This is my second order after having the crack yak-55 for a few years. Will be back for more.
The best in class Bi plane no better on the market awesome fit to all the parts.3d machine,this is my 3 from Rc Factory love this model
