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 *

By far and above the best 3D practice plane on the market. Flys very, very slow and easy to hover. I’d have to say this is my most favorite plane in the quiver. I bought the big Crack but this one IMO flys better.
Flies great but has build issues
After I got through the build issues (minor) I've flown it 30 to 40 times with not as much as a bad landing. It its 3D perfection. On high rates it rolls faster than anything else I ever had and yet I can take off straight up and it's so stable it can go for at least 5 seconds before I tough any of the controls.
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!
This Plane fly's like its on rails. On the maiden flight i was hovering doing rolling harriers and knife edge with no coupling love it.
Best "simulator" ever
Flies really well. Always ready to be flown wherever you can. Doesn't get any better. I have the mini and lite versions. This is a nice addition to the family for outdoor fun.
TH 39" EPP CRACK YAK-55 GREEN
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!
39" Crack Yak, fantastic!!
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. Thanks!
This is my go to
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 :-)
WOW! Love this airplane
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!!
One of the best overall Planes I own!
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!
