H9 33% Pawnee Tug Conversion

I gotta ask, if the tow point behind the canopy has worked for hundreds of tows, why do you feel the need to do a bridle? I had I don't know how many tows on mine, Marc Simmons another who knows how many hundreds, and all the ones that Horizon has been using.

Looking at your last picture above, I would put a 3/8" basswood stick across the fuselage at the intersection of the former and stringer under the door. Then add plywood triangles between the basswood stick and the stringer aft of the former. Tow release would be located just in front of the basswood stick. Forces created by the pull on the tow line should be countered by this added structure...IMHO. 😎

Enough full size stuff on here... back to business. Making some progress on the newest Pawnee. Wings are 99% complete, landing gear reinforcements are done. Waiting on some more packages to arrive in the mail to really make some more progress on it.

Going with Jim's plan to put the release closer to the CG, mounted on either side and using a bridle to connect it to the tow line. Still not totally sure how to go about reinforcing the spot for the release. Any thoughts?

I like the shout out to Horizon Hobby with the N number also! 👍

Doing some work on the Pawnee, thought I would post pictures. Also wanted to show the new realistic pilot I got. Steve K

Congrats, Pete!

We test flew the Pawnee that I assembled for a friend Saturday. It flew great, what an easy flying model, zero trim changes needed on the test flight...or subsequent flights. With the DA100 it took off at less than half throttle and at full throttle attained a steady climb angle. No elevator compensation needed with flaps deployed. Can't wait to tow with it!!

Look at you two!!!!!
Hard to believe only 3 years ago you just got serious about aerotowing. Very cool.

Way to go guys!

Took the Pawnee for Maiden. Flew well and towed Kevin's 233 at Harris Hill. Cool.

Well, here it is. Done! Not really, need to balance, set throws, and do a littl programming. Thanks to all that guided me through this.

Got the tailwheel mounted and connected. Went with the Whiterose Engineering Tailwheel.

Thanks guys! It's not mine...I built it for someone else I may try your top wing strut fitting idea, when I do the final balance after we get the spinner and a pilot!

Hi Pete,

She really looks great. Nice job. We Balanced ours by picking up on the top wing strut fitting. Flew the first couple of times and then moved the CG back a little further. We also added 1/4 inch more up elevator travel from book specs. The Sullivan 7 inch wheels are heavy but worth it. Am going to pick up a new tail wheel as that's the only thing I'm still not real happy with. I think a 1/3rd Scott 3200 from Ohio Superstar will be coming home from Toledo.

Have fun and don't worry. She fly's super easy and is great fun. We look forward to seeing you with that new toy.
