Default Scratch Built Avro Arrow

HI everyone I am new to this forum so this is my first post, I am looking for some advice/ideas as to why my scratch built pusher Avro Arrow would immediately bank to the left and into the ground. This was on my maiden flight, I managed to come out of this crash with slight damage to the left wing. I am using a Turnigy1450KV motor with a 8x4 prop and a 1000mAh battery 3 cell. I am guessing that it torqued into the ground, but would love to hear some of your opinions. I am considering putting in a 2700KV motor with a 6x4 or 5x5 prop as an alternative.

Thanks in advance

Is your scratchbuilt from plans or your own design. I have one that I built from dollar tree foam board from some plans I found. It has the same tendency as what you describe. Leading cause of this is hand launching with too much throttle. I launch mine at 50% till it is moving nicely then open her up.
I run mine on 3s with a power up 400 zoom 2200kv spinning a 5x5.
Also make sure that your wings are perfectly flat without twisting as that can also cause your symptoms.

Thanks for the reply Wrongway-Feldman, yes I did as well find my plans online except the guy that made the plans used a Gearbox motor, dont know alot about these so I am trial and erroring my motors. I will try the 50% throttle on the next round, I think I am still going to ditch my 1450 KV motor for the 2700KV that should help reduce the torque if that was the problem. I would post some pic but at the moment I am still trying to figure things out on this forum, so it may take some time. I also have a very short video of my maiden flight, maybe I will upload soon.

Here's a link to the plans for the one I built.
http://www.rcpowers.com/community/th...e-plans.14626/
Easy build and looks great in the air.
For a simple way to post video here just upload to YouTube and attach the link to your post.
Look forward to seeing yours.

Thanks for link to the plans, if things don't work out with my avro
after I try a new motor I will retry a build with those plans.
As far as pictures go I have tried three times to upload them
but get an error message.
