Just watched this for the first time tonight and all I can say is I'm damn impressed. Really nice build and I love that you even power articulated the aircraft attach points.
@@TuomoMooneyFlying What are your 2.0 ideas. We are looking at building tugs for 3 club aircraft, Archer, Arrow, 172, and a Van's RV10 . We are hping to use one design and modify the grip arms
@glenellyn100 that’s a good question. I would definitely modify the grip arms. The current solution uses a cable to actuate them but it hasn’t proven to be very good solution. The linear motor instead of being on the side could go in the middle of the frame and push the fork out or pull in as needed with kind of a scissor like mechanism.
Very cool! I looked into building something like that but couldn’t figure out a planetary gear for it. Thanks for stopping by the channel! Love your Grumman!
Excellent video, thanks! I have a 69M20C and attempting to build your example tug. Just wondering if you have any dimensions available for this project? Thanks again.
The rough dimensions were explained in the video, unfortunately I don’t have a drawing available. The long sides are 24” and the width was 10”. If I was going to do this again, the pivoting fork needs to be beefed up, and the articulating attach arms mechanics need more refinement. Closes great, opens not so great. Thanks for the kind comment!
Could you discuss your fork design a little. it looks like it pivots. Any issues with jack knifing while backing the plane up? do you have something to limit the travel? can you lock it? I have built 2 similar to this except for RV-6 tail wheel and now designing a version for a nose wheel
I operate a C172 off of a grass strip, with grass transitioning to gravel going into an open hangar, with some humps and bumps. This design looks great! Do you think it would be adequate to operate on grass and gravel? Thanks
The sprocket had a different hole dia than the main drive. But I found one that was slightly larger, it had a notch and the main drive had a pin. And then just tighten it down with a nut.
Thanks! I had to change the motor sprocket to a #35. Was a real pain finding a sprocket that fit the motor since the motor had a non-standard size shaft. The one I got was slightly oversized but was able to use it anyway.
@@msabol01 thanks! The sprocket was the most difficult piece, I did not find one that was an easy bolt on because the motor axle was not standard. I took a sprocket and then modified it to fit the motor axle, it’s still not perfect but it works. The screws were metal screws, nothing special about them.

Thank You! It was a super fun project, I do have some 2.0 ideas if I ever need to redo this 😁

Great video Tuomo! I may build one myself!! Thanks for the inspiration!!!
Thanks Manny! It was definitely a fun project!
Nice work. I have a tug that uses wired drill which works fairly well.

How much torque that electric motor to move the aircraft? My i ask
Enough to push a Mooney with full fuel up a small slope. But the spec of the motor is listed on eBay, just follow the link in the video description.

Yeah, there’s stoppers on both side of the fork arm so it pivots perhaps 10 degrees but not enough to jack knife
Great project! What gauge wire did you use and what size terminals for the battery? Thanks!

Never tried it on grass but you could get some extra grip tire for? It could work!
Hello, is there any way I can connect a trailer hitch to my J5 Cub and tow a trailer with it?
How do you connect sprocket to main drive wheel ?
The sprocket had a different hole dia than the main drive. But I found one that was slightly larger, it had a notch and the main drive had a pin. And then just tighten it down with a nut.
Do you have the plans anywhere and the files for the 3D printing?
Sorry, unfortunately not anymore. But the measurements were pretty straight forward.
Nice Job!!! What sproket you ended up using on the motor?
Thanks! I had to change the motor sprocket to a #35. Was a real pain finding a sprocket that fit the motor since the motor had a non-standard size shaft. The one I got was slightly oversized but was able to use it anyway.
@@TuomoMooneyFlying great project, may follow suit. Can you link the motor sprocket you used and screws you used.
@@msabol01 thanks! The sprocket was the most difficult piece, I did not find one that was an easy bolt on because the motor axle was not standard.

The link to the motor no longer connects. Can u provide info or new link. Please.
Thanks for letting me know! I updated the link, it should now work.
