DO NOT USE THE TRAILING LINK NOSE GEAR if you fly off grass.. my buddy and i both had the nose gear fail on a mild bounce on our planes .. on grass it tears the crap out if the nose when the strap that holds pivot link fails. I ran some numbers on the link that failed and it is way undersized in aluminum.. it should be made of steel at its current dimensions..

pic attached... i have two more that my buddy broke that look exactly the same.. my plane fared better.. when it fails on grass it digs in and stops the plane instantly ripping a nice hole in the plane as the gear and bulkhead pull out.. Maybe it would slide on asphalt? i tried to get a replacement from behotec via ultimate jets and they couldnt get one from behotec.. I went back and forth for a year and gave up... one of these days I will make a replacement nose strut link from some good steel and use parts i have from three failed struts..

I never used the trailing link on the nose only the mains. Too bad to hear that.
Looks like a few of us have had different problems with gear on this one.

Thanks everybody for the inputs......
I have received an email from Thomas this morning and he confirmed that he has the trailing legs in stock (I'm attaching .pdf document with info and pricing). I just need to send him a picture or my wheels and brakes in order to make sure that I can install them without any additional adjustments. I will also be buying additional strut and wheel pins since these are those that fail the most. They are extremely soft and they tend to bend easily.
It’s a shame that such a nice plane has a such a bad landing gear solution. Behotec’s are good products, but for sure they are not the correct size and they are not able to handle the weight or lateral forces.
I fly from a paved runway so trailing legs shouldn’t be a problem. Actually, In my Marchetti they work wonderfully……. I guess that this also should help with the tendency of this plane of skating back and forth down the runway from side to side.
Regarding the new wheel being offered by CARF….. I’m in agreement that they are ugly. I wouldn’t even install them in a IMAC plane.

all I am reading about the strut problem is so sad. After 5 years I finally sold my Tutor which I loved. A beautiful flying plane.
I replaced several nose struts and several main struts. It wasn't as if I couldn't land ( I made some beautiful landings with it) The struts were to soft and the tires were like rocks.
It got to the point that I became gun shy to fly it . The struts are about 100 dollars a piece and a pain to get.
Obviously I am not the only one to experience this.
I loved flying it, and I miss it.

The behotec trailing link nose gear is the issue. if they get the pics back up you can see where the link failed. i have a couple matching ones. When the link fails the plane drops on the strut and the wheel flops along in trail..on grass it is catastrophic to the nose gear mount/former. There just isnt enough material to handle the loads the way the strut is designed.. i would rather change 100 bent pins than have to piece humpty dumpty back together..

Thinking about converting my Tutor to electric behotec set using straight nose strut.
Do the trailing link main gear help prevent some of the bounce back up in the air when flying off grass?
Are the retract units based on the C50 unit so they would be drop ins?
Thanks

converting my CARF tutor to trailing link gear, because of nose gear failures had a machinist make me a custom reinforced collar so I can use nose gear trailing link that came with behotec electric set. If people are interested in purchasing replacement aftermarket collar you can PM me and I can try to put you in touch with the machinist.

My new project is showing up Tuesday so i got a fire lit under me to fix my Tutor. I dug a scrap of steel up and made a new link today. It was too cold to go to the shop and use the mill so the drill press, the belt sander, and a couple files took care of it. Some rustoleum chrome paint and you cant tell its not aluminum.

Great machining job. Thanks for posting the information.

Anybody using the electric version of the Behotec C-50 for the Tutor ? Experience ? Is the upgrade worthy ?
Trying to avoid the typical bending of the original landing gear.

Behotec c50 gear
using the C50 gear and nose wheel without any problems given the original set fro Air tech is so soft its like cheese.
Still using air and no problems so far. Using c40 on CARF Viper jet with top end brake and door controller which works very well. So I conclude that the electric version for the C 50 would be god as well

Skywarrior. Do you have any pictures of your tutor with the C-50’s fitted ? Just want to see how the plane looks with this landing gear. Thanks for sharing your experience.

Hi Gonzalo
I have used the electric C 50's on trailing link as well and I think they work very well. At this point I have C-50's on an A-10 and Prolinks on an Elan. Other than doors I am almost finished with air on retracts. They have more torque. The air cylinder on most jet aircraft I have had other then BV have all been undersized.
Good luck
