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 *

    This is the second foam plane I've built to try to learn 3D flying. All I can say is WOW!! I wish I'd started with this one (the other was not from TH). I enjoyed the build and flew it for the first time today - AWESOME!! I had high expectations and I'd say it met or exceeded them all. Excellent in every way! Take your time to build it straight & true and you will love this airplane - mine didn't even need one click of trim - perfect - makes me look way better at 3D than I know I am. I just want to fly all the time now!

    Love this plane. I am an old guy and just getting into 3D. This airplane makes it seem easier than it really is. No more falling out of hovers and slow post stall flight like my other 3D planes. I can see improvement in my capabilities every day thanks to it.
    I bought the power package and is perfectly matched. Seems to need a little more aileron throw than the stock arms provide. I can only get 35 degrees with my radio endpoints maxed out.
    First flight was a breeze and my grandson flew it with ease.
