Angelo, I bet he has thought of that, and included the corrected thrust in the motor mounts.

With everything else he has thought of, I'd say that is safe money.

Thanks,

The motors are at zero with the cord, then the wing sets with 2 degrees up incidents, that gives the motors there proper incidents.

Thanks, DAG

This should clear up your question. The motors have 1.5 degrees out thrust, or in depending on the way you look at a pushers. The trailing edge of the wing is still swept but not at the same angle as the motor firewall.

Thanks, Dag

She has been really slow this last 2 week getting the gear developed. But now I am back to the parts that are really fun, building on the airframe.

I am still not awake, I just got the tune in my head. LOL

I will still be wanting to look at a few of your locking pin things, can't remember what you called them, still waking up. Been working all 3 jobs hard lately, Family, work, B-36 .

Thanks, DAG

My word dag. Seeing the work involved in this project makes me want to hang my head in shame for ever thinking some ARF plane kits were tough.

IMHO you need to keep it in perspective, heck I have built ARF's I thought were tough because the were designed and built by someone else that expects you to understand (sometimes) bad directions with really bad photos of how parts fit. I also have spent over a two thirds of my life designing my own things. If you are the designer it goes a lot easier than you would think. I had a ARF once that all the directions were written in a language that I could not even read, and no photo's, when done I had a ton of parts left over, but she still flew great. I love to torture my self by pushing my design skills, but it is not anything anyone could do with enough time. I have been thinking about this plane since I was 12, at 15 I wanted a control line of this B-36. I am 46 soon and now building my dream, just hope she flies . I will tell you this, I am very surprised at how it has gotten so much attention, This thread is approaching 75k of views, that is something I never thought would have happened.

Also if anyone ever wants to ask anything about this project or designing, just ask, I try to answer all. And if I don't answer, ask again, I must have forgot to answer the first time.

Someone once asked for my 3D of my robart air tank, I still can't remember who that was and can't find the thread. Ask away!!!

Thanks, DAG

probably because they have a knack for copying designs...

especially strategic designs...
