Annmarie,
Thank you for taking the time out of your busy schedule to comment on our posts. I would certainly like to have some hard facts, as to why this plane is designed this way. Please do not get me wrong, as i am not bad rapping GP, i think you folks have done a fantastic job on this airplane, as i have commented in my earlier posts, there is "no way" I could have built and covered this airplane for the price I paid for it.
I think my biggest gripe was before i flew the plane, i noticed the huge amount of "upthrust" in the firewall, so I did notify you folks, and was told that it was designed with that much upthrust.
So when i made the first flight, unexpectedly, the plane pitched up nose high on take off, and i nearly lost it! I had to put 28 clicks of digital trim in it to get it to fly level. So i started experimenting with the thrust angle, I even had the engine at 3-1/2 Degrees of down thrust. this did not cure the problem, as i still had to put down elevator trim in the plane. So this told me that i also had an incidence problem, which i corrected by dropping the front edge of the wing.1/2 degree. I put the engine thrust angle at 1-1/2 deg. down thrust. The plane now flies very respectable.( Weight and balance were checked numerous times, and are to specs.) I believe the plane has two problems, thrust and incidence, as i had to change both on my plane.
When checking all the posts on the web, i find out that it is not an isolated problem with just my plane! Like i said, earlier, i know of 5 of these planes that i have seen personally ,with my own eyes, that have the same problem.
Like you just stated yourself, you believe it is a wing/incidence problem too. It is good to know that you are making your R/D guys aware of this problem, I hope you post a reply as to what they find out, is causing the plane to require lots of down elevator trim.
Ann, I do apologize for making the statement that you guys were " dead wrong", that is not accurate, as you stated. but i guess by making that statement, i got Great Planes attention. As for my emails, not being answered, you could be right about it being an innocent mistake.
Again, thanks for taking the time to answer our posts, and also my thanks to RC Universe, for such and outstanding job they have accomplished with this website!
sincerely, Paul
