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.
coming from balsa models this was a joy to build and fly. Will not go to the field with out it, now what's next :-)
I purchased the YAK 55 39 inch with all of the power combo pack and recommended accessories by Twisted Hobbys. I have to say that I don't care for the control arms for the elevator and rudder and the clevis hook ups. So I went outside the box and made my own which was much easier and just as effective. I flew the Yak for the first time yesterday. Wow, what a great flyer!! Immediately was doing prolonged hovers and torque rolls. Love this airplane. It was a moderately windy day but the wind didn't seem to be much of a factor. I highly recommend this winner!!
This is my go to plane to fly because it can fly in all conditions from windy to calm. With the stock combo the power is perfect. I also get 7 minutes with a 800 mah 3 cell battery. Hover to snaps this is my fun go to plane!
Always quality first with Twisted Hobbies,The quality ,price and service is unbelievable.I love this model fly's flawlessly.As always more than Satisfied. One note if u use the wooden motor mount I always pre soak it in thin super glue makes it solid
I find that the motor mount wood seperates after a few flights, The landing gear mounting is not designed for grass fields, one must put a plate on the top # using long #2 machine screw fasted the landing gear to that.
Other wise I am delighted.
Super fun model. Perfect size for outdoors and battling the winds out here.
