TH 39" EPP Crack Yak-55 HCG

13 reviews Write a Review


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 *

    My Crack Yak-55 39" Is the best fun flying than anything I have.

    Purchased 39" Crack Yak it was great 3D Fun, Fun, FUN ! Then I flew straight into a iron wind vain. Bad crash at full throttle damage to front was Total. But new pieces of foam from another plane junk yard and a lots of TLC I was back in the air. But I realized I had to get a new one because this poor plane looked like Frankenstein. Building new beauty now. I think this model is almost indestructible.
