TH 39 CY G


The 39" Crack Yak-55 is finally here... the long awaited bigger brother to our well known Crack Yak-55 model. New wing core with tapered tips is one of the new features creating a much larger flight envelope for strong wind capabilities. Other items include added T-Canalizer and new SFG placement for amazing KE stability at any alpha. This is a fresh new ground up re-design. Chris Jewett's original world renowned 32" Crack Yak-55 has been our go to foamie and it is now crafted into a larger size for an even more intense flight envelope.

Those that are familiar with the previous 39” models will appreciate the new hardware and construction methods with adjustable push rod assemblies EPP bracing techniques for easy assembly. While creating a new ground up air-frame the duel aileron servos were re-located to create a plush/clean look. The over all flight envelope has increased greatly giving a sense of unreal control authority and increased roll rate was also achieved with the addition of outer counter balance tabs. This model was designed for the pilot wanting to learn the “next step” and also those who choose a balsa 3d model alternative.  * Spinner not included *

    Great first 3D plane

    I love this plane! It is my first 3D plane and I got it to try and learn this type of flying before I try to fly some bigger more expensive models! The only reason I didn’t give it 5 stars is due to the build instructions aren’t as clear as they could be and it would have been nice if it came with the instructions rather than finding the pdf online. The plane itself is great! My first time with this type of plane and have not had any crashes yet!
